Title: Surplus amps
Post by: akyatbundok on Aug 17, 2003 at 08:01 PM
I was at the port area this weekend to help a friend shop for a good integrated amp.   He was planning to setup a 2ch system because the wifey wasn't gonna let him spend double digits on a 5ch HT.  So he went AWOL that day and dragged me along, since i had a bit of experience buying surplus stuff.  The plan was to buy a surplus integrated amp & a bnew speaker for less than 9k.  With that budget, he doesnt have too many choices for speakers.  I recommended that he get a wharfedale diamond 8.1.

For the amp, he had alot more to choose from.  In one of my recent scouting trips, i listed down the brands/models of amps that are still in good condition so that i could get more info from the net when i get back to the office.  There was a Sony ES, a few of Onkyo Integras, and alot of silver Pioneers & Technics.  There were also obscure brands like Trio & Lo-D, which turned out to be Kenwood & Hitachi respectively.  Anyway, since he didn't have the speakers yet, I ended up comparing these 3 brands at home.

1) Onkyo Integra A-819RS (1983) and A-817XX (1987) - 105W x 2
(http://203.131.66.146:8080/onkyo1.jpg)

The amp that i'm currently using to power my fronts is an Onkyo Integra w/c i bought for 3.5k.  It sounds more detailed and more powerful than my 5ch Denon receiver, w/c i bought bnew for 21k.  This is an "RS" model which came out in 1983.  The ones we saw at the pier were "XX" models which went out at around 1987 but had a lower model number (A-817).  One thing you will notice at the pier is that the power ratings for all the amps are measured in power consumption, not power output.  So the higher the consumption, the higher the price.  The Onkyos consume 210W so that would place the output to somewhere around 105W per ch.  These amps are HEAVY, with a huge power supply and 2 large caps.

2) Sony TA-F333ESX (1986) - 105W x 2
(http://www.niji.or.jp/home/k-nisi/ta-f333esx-h.jpg)

There were 4 Sony 333ES amps in different conditions that were selling for around 4-5k.  The one in best condition still had the wood side panel and was selling for 5.5k.  We were able to haggle down to 4.9k.  The ES product line from Sony is their high-end stuff, w/c is similar to Onkyo's Integra and Pioneer's Elite.  I knew that the 333ES was going to be good because i saw it in a list of top-rated amps from a Japanese site.  This is even bigger and heavier than the Onkyo, with a bigger power supply and 4 large caps hidden under the heatsink.  My friend said he almost had a slipped disk carrying the thing (19kg).  The sound was hard to distinguish from the Onkyo; both amps were clean & detailed.  The Sony "probably" sounded warmer, with slightly more bass, but I have to confirm that with a second listen.

3) Luxman LV-103 (1984) - 60W x 2, hybrid tube + solid state
(http://203.131.66.146:8080/luxman2.jpg)

And finally, I couldn't resist buying on the spot the Luxman amp even though i wasn't really shopping for an amp.  The 2 tubes peeking out from a small window was what caught my attention.  I couldn't hide my excitement w/c was a bad mistake on my part bcoz the storeowner decided to ask 4.5k for it even though this wasn't as powerful as the other amps.  We were able to haggle down to 4k.  I assume its a hybrid amp with a tubed pre-amp stage, or at least it may be a line buffer similar to the Musical Fidelity X10-D.  Either way, it made my CD player sound like an X10-D was connected.  This amp sounded better than the Onkyo or Sony on vocal & acoustic music at moderate levels.  The highs were tamed and there was definitely more "body" in the bass as if an equalizer was used.  Unfortunately, it doesn't sound as good when you turn up the volume.  Too bad it doesn't have pre-outs, I think its only weakness is the power output stage.  You can tell that from its small power supply and small capacitors.  In fairness, i was auditioning it on 3-way floorstanders with 10-inch woofers.  I'll do a 2nd round of listening test with a small 2-way bookshelf and see how they compare.  But i have a feeling that this is the amp that i will put permanently in my planned bedroom audio system.

I went there just to accompany a friend buy an Onkyo because he liked mine.  I went home with 2 additional amps.  Geez... when will i ever stop.  he he

sir how much ung sony es amps dun?mas ok cguro if i buy exactly 3 stereo amps,and connect it to my dvd player..1 for the fronts,1 for the surrounds,and one for the center and a passive sub..? maganda kaya tong idea ko ;D ;D,it will look really nice kasi..iba iba contols for the fronts,center,sub,and surround..meron din ako active sub na nakakabit ngayon sa player..kaso i would like to add one more 10 inch passive one...

johndoe, dalawang klase ng sony ES ang nandun... yung 333ESX saka 222ESJ.  di ko natanong yung price ng 222ES pero yung 333ES ay nasa 4k ang price pagkatapos ng tawad.  naisip ko na rin gawin yung 3-amps dahil mukhang weak link ang receiver ko, pero mukhang inconvenient dahil wala kang master volume control.  mahirap parati mag adjust manually ng tatlong amps.  tsaka todas ka sa electric bills pre, 650W total nung tatlong amps hehe.

rare find yata yung luxman pre, dahil madalas ako dun sa pier pero first time ako nakakita ng tubo doon.  last week lang wala yun dun eh.  dalawang brands ang mahirap hanapin - luxman & accuphase.  kung makakita ako nun bili agad, approve without thinking.  ang impression ko kasi sa luxman at accuphase ay ka-level niya ang nakamichi.  yung mga amps nila ay usually isang dangkal ang taas dahil super laki ng power supply.  medyo exception nga lang yung nabili ko dahil mahina.  pero sa sound quality patok.

actually accuphase is of a higher level than nakamichi, the luxman amps sound a little bit better as well, especially if you can find the champagne colored ones with wood side panels  ;) The tube hybrid you got is a bargain maybe changing the tubes will improve the sound, especially at higher volumes...baka luma na yung tubes inside and near the end of its lifespan. or maybe just a little cleaning if the insides and checking of any loose solder should do the trick.

Those integras and sony es's you saw are those that are released only in japan and are the top of the line at the time, you are right in your opinion that these amps sound much better than the amps on entry level receivers. Plus they are heavy too due to the large trannies and caps inside. ;D

Post by: akyatbundok on Aug 18, 2003 at 11:54 AM
meron akong listahan ng amps na "approve without thinking" w/c is a result of my research before going to pier.  share ko na lang para mabili agad ng iba, otherwise mauubusan nanaman ako ng pera kung makita ko ito:

kenwood L-series: L-01A, L-02A, etc.
these were kenwood's top-of-the-line muscle amps in the late 70's and 80's.  some of them were priced at half a million yen, and that was before inflation.

sansui au-907x
this is one of the best amps built by sansui.  manufactured in the mid-70's during the company's prime, before quality went down in the mid-80's.  there are a few 3rd generation 607F that can be found at the pier but the 607 is not as good as the 907.
(see the internals and be amazed: http://www.niji.or.jp/home/k-nisi/au-d907x-h.jpg (http://www.niji.or.jp/home/k-nisi/au-d907x-h.jpg))

pioneer sa-9900
also from the mid-70's the top-of-the-line model during pioneer's "silver age".  lower models can be found at the pier but ill reserve my purchasing until i found one of these.  distinguishing features are the handles at the back, and the speaker/RCA connections at the sides.
(internals: http://www.classic-audio.com/pioneer/pics/fxfthumb/i_sa9900.jpg.jpg (http://www.classic-audio.com/pioneer/pics/fxfthumb/i_sa9900.jpg.jpg))

pioneer a-717, a-838, a-636
these are pioneer's dual mono designs from the 80's during the "black age".  my friend and i saw a 636 at the pier selling for 4k but unfortunately one of the knobs was broken.  nevertheless it was sold when i came back to check.  neither one of us was able to carry it alone.  they weigh between 20kg to 30kg.
(internals:http://www.niji.or.jp/home/k-nisi/a-717-in2.jpg (http://www.niji.or.jp/home/k-nisi/a-717-in2.jpg))

kenwood trio ka-9900, ka-9300, ka-8300 & ka-7300
these amps have similar dual mono design.  separate power supplies and caps for both channels.  they look very outdated so u may be able to get them cheap for 2.5k.  very rare to find dual toroidal power supplies in an integrated amp.
(internals: http://www.niji.or.jp/home/k-nisi/ka-9300-in.jpg (http://www.niji.or.jp/home/k-nisi/ka-9300-in.jpg))

any luxman & accuphase amp
just an observation while i was working there.  luxman & accuphase were always very visible whenever a recommended list was published in the stereo mags, and always in the hi-end bracket.

akyatbundok,

how about those onkyo and yamaha sa pier? wala ka bang reviews sa mga ito? may mga models din ba silang maganda ang reviews?
Title: Re:Surplus amps
Post by: akyatbundok on Aug 18, 2003 at 01:13 PM
45mm, these are the onkyo & yamaha models i would be interested in:

Onkyo Integra A-817XX, A-819RS, A-820GT
Most integras at the pier are in this category.  They basically have the same 205W - 210W power consumption so their output power is probably 100wpc and above.  The 820GT is rated 110W/ch.  Model numbers that i've seen are 817 and 819.  The last 2 letters indicate the year of manufacture, where "XX" are the latest models (1987).

Onkyo Integra A-2001
This is a black 1987 model rated at 150W/ch.  It can deliver 490W per channel on 2 ohms.  It also has built-in DACs so you can connect your CD/DVD player thru optical or coax digital cable.  Definitely, approve without thinking.

Yamaha A-8, A-9 & AX-2000A
By all means get the 1990 model AX-2000A rated at 150W/ch RMS.  It delivers 600W per channel on a 1 ohm load.  The A-8 and A-9 are 1979-1981 models that are rated 120W-150W/ch.  Very high SN ratio at 120db.

akyat,

Congratulations on your new found gems above ;D.

Your findings and reviews are very helpful.

I hope you can share more listening experience with your amps.

More power to your hunting expedition.

In due time, I will also explore the jungles of Pier for those GEMS.

i didnt see too many marantz amps there except for one that's hidden at the back of tatang's shop.  he said its defective so i didnt insist.  but i did notice it was one of those thick amps with gold plated jacks.  i wasnt able to list down the model number.

but this one would be a good buy if u can find it: marantz pm-94.

Post by: akyatbundok on Aug 20, 2003 at 09:15 PM
I did more listening tests on the 3 amps, this time in my bedroom using small detailed bookshelf speakers (mordaunt short ms-902).

The onkyo integra is more suited to speakers with a laid back tweeter.  I remember hearing improved definition when i still had my AE speakers.  One of the problems i had with the Aegis One was the rolled off high frequency.  They did not match too well on my Denon receiver w/c was warm sounding.  The result was that it sounded dull on movies (though magnificent on music).  But on onkyo the AE speakers had better detail.  When i switched to the brighter mordaunt speakers, the HT experience improved on the Denon receiver.  But on the onkyo there was a bit more sibilance than usual and the midrange became laid back.

The sony ES seems to have better balance on these speakers, with less sibilance and more voice.  Bass is about the same as onkyo.  On the onkyo, i turn the volume knob up to 10 o'clock only.  With the sony, its 11 o'clock.  I dunno if this is an indication of power reserve, but if it is, it would seem that onkyo can go louder.

The luxman had more defined midrange & midbass.  This is my preferred amp for vocal & acoustic music because it sounds more natural as long as you dont turn up the volume too much.  I fried one of the tweeters while testing the luxman on hard rock at loud volume.  Dunno if its the amp's fault or the speaker's fault.  Good thing the speaker is still under warranty, it shoudnt have conked at that volume.

More listening tests:

Back to my floorstanders in the living room.  I tested the luxman for a while, and im convinced it will stay in my private audio setup.  I wanted to hear how it sounds with an X10-D connected to my DVD player, and found some over-emphasis on the midrange & midbass.  Seems it doesnt like any help on the signal, except maybe for music that sounds thin.

Its now a contest between the Onkyo Integra & Sony ES to power my floorstanders (ms-908), since the luxman couldnt drive them at loud volume.  The onkyo is better balanced this time, with less of the sibilance i heard on the bookshelf speakers.  The problem now is i couldnt tell which amp is better.  Everytime i switch to the other amp, i tell myself "this sounds better".  Is there such a thing as an amp switch for A/B testing 2 amps on 1 set of speakers?

sori bro, there are no dd/dts receivers at the pier, only pro-logic or stereo integrated amps.  they're useful only if you intend to setup a really cheap dedicated audio system that sounds really good for its price.  most of them are in bad condition, but once in a while a real gem turns up.   i usually dont expect to buy anything when i pass by the pier, but i bring my usual budget just in case.  like BuLLet said, patience is a virtue.

after buying a wharfedale diamond 8.1 yesterday, my friend's system is now complete.  he spent a total of 8.8k for the amp & speakers.  he also finally admitted to his wife where the money went.. he he.

latest sighting:

http://www.niji.or.jp/home/k-nisi/ax-z911.htm (http://www.niji.or.jp/home/k-nisi/ax-z911.htm)

found this integrated amp selling for 4.5k but i didnt buy it (hav enough trouble choosing between my amps).  its a 1987 model rated 110W + 110W at 6ohms, 0.0035% THD.  like the onkyo a-2001 posted above, it has a built-in D/A converter but its only the usual 16-bit 4x oversampling.  if your cheap dvd player sounds awful on cd playback, the manufacturer probably skimped on the quality of the DAC.  if thats the case you may want to check this out.

The pre- main amplifier where Victor sells in 1987. Victor first D/with A converter built-in amplifier, simple
It was the labored work which throws the amplifier technology and digital technology of the Victor tradition in future design. Especially, the D/A converter

Victor AX - Z921
DIGITAL BASIC INTEGRATED AMPLIFIER
XXYEN 99 and 800
The pre- main amplifier where Victor sells in 1988. AX which is sold in the preceding year - it strengthened Z911 substantially, was complete
It was the D/A converter built-in type amplifier which has contents. Especially, the D/A converter section focusing on strengthening is assured,
It increased.

As for the largest modification point, input section clogging to immediately before the D of the digital data which is sent from outside/A converter
It was in loading the "K2 interface".At the time of waveform transmission of the digital signal, jitter (the differential time strain) and

It increased. To adopt those of 8 time over sampling to the digital filter, in the D/A converter, subordinate position
The bit was separated, the superior bit and electric current 18 bits L which are added R independent combination 4DAC was loaded.

john5479, thanks for the japoks english translation.. hehe  ;D

its hard to decipher the babelfish translation but it seems to have these neat features:
- virtual class A operation at high 120wpc thru signal prediction
- short 0.5m signal path from digital signal to speakers
- digital & analog circuits are completely isolated from each other

if i understand it correctly, it simulates class A mode at 120wpc by predicting the signal at the D/A converter and then switching to class A (???) when needed.  anyway, the japanese just dig high-tech stuff thats why their marketing materials always contain technical info.
Title: Re:Surplus amps
Post by: john5479 on Aug 23, 2003 at 11:41 PM
How does this amp work ?

to put it simply...you connect your cd via digital out (optical) to the digital in of the amp (optical) and then it converts the signal to analog then gets amplified  ;) I doubt the class A thing though, but still wonder how these amps perform.
Title: Re:Surplus amps
Post by: akyatbundok on Aug 25, 2003 at 01:20 PM
onga sir, sabi sa literature "pure class A" at 120wpc. that sounds too good to be true.  i guess in a way they're like the speaker cable companies using technical jargon for marketing.  di ba jofkevski?  ;) nga pala bro, how about a review of ur A10 amp, that one is also a keeper.

to be safe, i would just think of the victor ax-z911 as simply an amp w/ a built-in DAC.  my friend was planning to use his pioneer 535 dvd player for music playback thats why i became interested in this amp.  he bought that player from me.  i remember when i first heard the older 525 play music cd's -- i regretted selling my cd player.  so before he kicks my butt i would tip him on getting an amp w/ DAC.  ;D ;D ;D

Hi guys,

I own a used (but in mint condition) Yamaha MX-1 power amp. Got it for a hefty P45k. No I do not have lots of bucks but that is how much I yearn for this amp so talagang pinag-ipunan ko!

I came to know this guy in one of the hi-fi net forums who happens to be married to a Filipina. He was once a sales manager in one of a high end hi-fi store in New York City and was able to own several highly priced esoteric amps until he got to hear the MX-1 and he never changed amp since then. He was the one who persuaded me to buy the amp and I am glad I did.

The Yamaha MX-1 is a legend like the NS1000 speaker as these units were made only in limited quantities. Just to give you an idea on how beautiful this amp sounds – read on:

1. The MX-1 can easily pump 1000W into 1ohm other well-known hi-end brands will be choking at this point. Most other brands would not even recommend a load of 2ohms.

2. MX-1 employs C-Core twin 700VA(1.5Kva total) transformers. It is dual mono design and in pure Class A operation.

3. The MX-1 has 4 massive capacitors totaling 10000 Pico farads of capacitance and ten audiophile grade MOSFET (not bi-polar) transistors per channel.

4. The MX-1 has two 700VA transformers, which form the major portion its weight at 24 kg!

5. The MX-1 has a distortion figure of .008% THD at 1KHz, and an SNR of 125dB. With super fast slew rate and a high damping factor of over 350, you get an exceptionally fast, high resolution amplifier which makes complicated things like guitar strings come alive. Most amplifiers, even the so-called audiophile ones fail in this litmus test.

6. Maximum power consumption is at 1,950 watts (patay kang bata ka pag dating ng Meralco bill).
 
All these boil down to one thing – a sweet natural sounding amplifier with enough reserve power to handle even the most demanding musical load.

Those who may or have stumbled upon this particular unit might want to audition it and then get back at me to disprove what I have written here!

Listen to it – and if you like what you hear do not hesitate to buy it, it is a treadure!

Hi guys!  I have a Nikko 9095 amp given to me by my uncle in the states in 1993.  I think it pumps out around 90W/ch.  Silver yung front finish niya pero wooden na yung nakapalibot.  I tried surfing the net pero I can't seem to find specs and reviews of this receiver.  All I know is that it was circa 1979.  

My amp very closely resembles the one found in the link below except that mine has a mic input with sliding volume/level control.  Medyo baliktad din yung location ng ibang knobs.  Other than that medyo pareho na talaga.

Balak ko kasi siya gamitin for a budget stereo setup.  I might buy a surplus CD player and use wharfedale diamond 8.1s.  Okay kaya itong amp na ito?

Are those surplus amps at the pier rated at 100 VAC?  If so, do they come with step-down transformers commensurate to the amp's power consumption requirement?  Thanks.
Title: Re:Surplus amps
Post by: jofkevski on Sep 05, 2003 at 11:19 AM
They do if you want, siyempre at addl price (normally 500). As to your previous question, some amp in pier has jumper at the back for pre-out/main-in. Tis means you can use them as separate amps. One of the amp still in pier is one of the famous marantz quartet-A technology - PM-74D model (about P4000) which is similar to Yamaha MX-1 in low-impedance capability. Di ko na kinuha because I like the NEC-A10II.
Title: Re:Surplus amps
Post by: akyatbundok on Sep 05, 2003 at 01:29 PM
eto ba yun jofkevski?  the NEC A-10II weighs a back-breaking 24kg!  this is due to its dual mono power amp section.  separate transformer and 4 large capacitors for each channel.  the original A-10 weighs 20kg.  a few years onwards and the A-10X weighs 31kg!  how does it sound sir?

Yes. I think I already shared this to you when I first published the URL of those amps you are now describing/sharing to other pinoydvd members sa YAMAHA thread.

The A-10II which employed FET components sounds big at it looks. very crisp highs on my 8.3, very brute bass, and like in every instrument sound - there seems to be a background of pure silence. I mean - parang individualized detail ang bawat sound. No hum and no hiss and pure silence when there is no passage of signal.

60wpc sa 8ohms, 80wpc on my 8.3 (6ohms). gets hot at 9 oclock but already sounds loud. If i switched separate, the sound is lower (in volume) dahil bypass na niya ang pre-amp (as if I inputted my source to MAIN-IN jack sa likod).

It is currently my music amp sa haybol ko. will not buy for now sa pier because A-10II is so good, unless I can see the model that I am waiting for (he he he). the XIIII kung lalabas man siya.

Only 200 A-10II were produced in japan, and was a sought after amp that time. Thanks for John5479 for a good lead to understand japongo. This gave me a lot of time to waste to understand fully my amp and its history.

Siyangapala, the behemoth XI is out in pier when I bought the A-10II. the fastest, sweet-sounding amp that ever came out of Japan - so they say, selling 7,500. So fast to its disadvantage, that it will oscillate at the drop of a hat - so they say again. The trick? power it on with headphone or speaker connected, or else, you will have a pop corn transistor inside the amp. he he he

Title: Re:Surplus amps
Post by: akyatbundok on Sep 07, 2003 at 04:13 PM
johndoe, i use REC-OUT to connect my sub, but better if your amp has PRE-OUTs so you have one master volume control.  since i sold my 5.1ch receiver and waiting for my new 6.1ch, i've been watching movies in glorious 2.1 channels.  i only miss rear effects but the sound is just as dynamic.  makes me wonder why we're adding more channels and reducing watts per channel rather than the other way around.

i got my 2nd luxman amp from isak0411 last friday.  bought it as soon as i saw it in the buy/sell section... it got sold in 2 hrs.  btw isak, nice cd collection bro.

it sounds just like my lower model luxman, but with more headroom in the power section.  i clobbered my older luxman during testing -- now it won't switch on!!  sayang... mukhang nagtampo sabi ni julsp.  that's the trade-off with buying surplus stuff; you take a risk because you don't really know its current condition; there's no warranty and you don't know how it really sounds until you bring it home.  that's also why they're priced so cheap!!  as long as the risk/price isn't too high, i'm game hehe.  i've had the onkyo for about 8 months now with no problem whatever i throw at it.

as for the sound of the luxman hybrids, i would describe them as sweet/natural, very detailed and slightly laid back.  it turns out my initial impression about the bass was wrong: its actually leaner compared to the much bigger onkyo & sony.  its a very good amp for intimate listening though.  with its detail/resolution at moderate volume it kills my other amps.  but i feel it wont do very well if i want to rock the house.  too revealing of bad recordings, w/c is 95% of what i have.

Post by: akyatbundok on Sep 09, 2003 at 02:45 PM
hi av_phile, i still switch amps the hard way -- disconnect everything, then reconnect everything.

its the sound that fascinates me, how different amps have different characteristics.  i have this habit of gobbling things up when it becomes my flavor of the month.  at one point it was banana plugs -- i was trying everything i could get my hands on (that i could afford).  i was really looking for The One banana plug to use in all my speakers.  its kinda expensive to choose gear thru this "collect & select" method, so luckily i didnt try this with $$peaker$$.

i guess the same thing happened with amps.  didnt really plan on collecting, my original plan was to buy a bnew entry-level integrated amp with a budget of 15k.  but things changed when i got hold of my first surplus amp.  i didnt expect it to sound that good.  with 3.5k off my budget i still had money left to play with.  so while accompanying my friend jojo at the pier, i thought: with the money i had left, why not spend the rest of it on several amps, choose "The Ultimate One", and then sell off the rest to recover my cost.  so thats what i did... only problem is, i like 'em all, so i didnt get to do the last part... maybe someday.   ;D ;D ;D

in the process i learned alot about what kind of sound i like best.  for instance, one of my favorite vocal tracks gets presented 4 different ways, and i go back and forth trying to find out why they sounded different, and why i prefer one amp's presentation to another.  one instrument isnt too evident in one amp, yet it stands out in another.  bass quality is also different; one is well extended, but another is tighter.  they also seem to have different optimum volume level.  in a way im teaching my ears so that when im ready to spend a big amount of hard-earned moolah i would know how to choose.

johnlen, i think you're already in the big league with the MX-1... while i'm still fiddling in the 100wpc integrated range, you're already in the dual mono 200wpc separates range.  while i'm doing trial & error risking my 4k on a possible lemon, you went straight to The Ultimate One.

ingat lang tsong sa pagbili: everytime you buy surplus units you risk your money.  kailangan lang gamitan ng matinding pagtimbang ng iyong desisyon.  kahit i-test mo dun sa pier, hindi maganda ang tunog dahil sira-sira gamit nilang speakers.  maririnig mo lang talaga kung maganda o pangit pag nasa bahay ka na at nakapag bayad ka na.  dun sa apat na nabili ko, yung isa bumigay na ang relay switch, peborit ko pa naman tunog nun.

yup!  meron doon stereo amps worth 2.5k.  pero ito yung mga low-powered silver retro look na pang 70's.  nag test kami nung technics sa7700 against onkyo integra and luxman pero masyadong bright ang tunog, halos walang bass.  medyo madumi pa yung knobs kaya may malakas na static sound pag adjust mo ng tone control.  if you can spend an extra 1k, this would be a better bet: Denon PMA-390.  i've had 2 of these already.

this model was my very first amp, bought in japan in 1993.  there's still one selling at the pier for 3.5k.  the specs doesnt say much about its power at 50wpc but it can go loud & clean... 70wpc in 6ohmz, 100wpc in 4ohms.  i once attached a 4ohm cerwin vega 12" passive car sub in the left channel.  stupid me, i attached it in parrallel to my speakers, so the amp was probably carrying a 3ohm load all that time... a few months later the relay switch stopped working.  anyway, when it was still working, it was pretty darn loud & clean.  my favorite track then was the chesky drum test.  you could feel the pounding of the drums in your chest.  its got Denon's trademark laid back & warm sound as i realized 6yrs later when i got a Denon receiver.  this model is still in production in japan as the remote-controlled pma-390IV.  price & specs would put it in the same market as nad c320 or rotel 931.

be careful when buying there... make sure its not a lemon.  ;)

di ako sure eh, pero mukhang parehas ang loob... nakakita ka ba doon sa pier?  usually sinusulat nila sa harap around 370W ang power consumption nyan, pero ang rms rating ay 160W + 160W, 8ohms.

adriane,

yung lv-103 na nabili ko sa pier, nakatambak lang sa kuwarto... di ko pa napapaayos eh, nasira yung relay switch.  sa ngayon naka standby lang siya as spare parts in case masira yung isa.  may pila na nga dun eh kahit sira hehe.

yung lv-105 nabili ko yun kay isak dito sa pinoydvd, pero nakuha din niya sa pier.  pareho yata tunog nila except lang yung 10'oclock volume level sa 103 ay 9'oclock ang equivalent sa 105.  kung sa appearance mas malinis ang condition ng 103 esp. the tubes kitang-kita thru the glass window.  sa 105 hazy yung glass so hindi makita yung tubes.

bro akyat, san ba parte sa pier yung mga surplus amps na mganda? sorry wala na kasi akong time scroll yung pages eh, saka dati nagpunta na ako dun nagtanong ako ng amps ang price 4000, eh ang brand new nasa 4500 na eh. tapos depende pa daw sa wattage ang price. yung pinuntahan ko is yung mga malapit sa nagbebenta ng aircon na surplus.
Title: Re:Surplus amps
Post by: akyatbundok on Sep 24, 2003 at 05:09 PM
maraming aircon nasa labas yan ng mga tindahan ng tv right?  sa bandang kanan...  sa dulo nun mayroon gap na canteen.  i think may ATM pa yata.  then lampas pa nun may tindahan ulit ng mga tv.  sa dulo nito may store na maraming big speakers na patong-patong.  yun ang first store na may maraming amps, cd players & vhs players.  then lampas pa nun may gap ulit, tapos may maliliit na stores ng tv and amps.  pagtawid mo sa kabila ng street, may stores ulit ng amps, cd players & speakers.

ang price depende sa power consumption dahil di nila alam ang totoong RMS power rating, so assume na lang na pag 2-channel, power rating is a little less than half the power consumption.  dats why i always go for 200W and above para at least malapit sa 100watts per channel RMS rating.

Title: Re:Surplus amps
Post by: nerveblocker on Sep 25, 2003 at 04:26 PM
I suggest that when buying stereo amps bring your speakers along so you'll have an idea how it would sound in your set up.  Remember that speaker-amp matching are more important than good amp reviews.  Even if an amp has good reviews, it might not sound good on the speakers that you pair it with.

In my little experience with jap surplus amplifiers, the best sounding i've heard so far are the Luxman or Alpine/Luxman amps.  

Just my 2 cents. ;)

good idea nirvblakr!

pero pag bulok rin siguro ang speaker mo (katulad ko ;D), eh huwag mo nalang dalhin.

mga sir, balak kong bumili ng bagong lumang amp. pinag-pipilian ko eh;

Trio KA-7300 (Left and right independence separate power source adoption 2 power transformers 4 block capacitors -Effective output 65W + 65W)
P 2,800

Sansui AU-D607F Extra (circa 1981, 200+W )
P 3,000

Sansui AU-D707X (circa 1984, 200+W)
P 4,200

Denon  PMA 701 (175W)
P 3,000


i'm buying the amp for my turntable setup, so i don't need digital amps. maganda yung Sansui kasi may MM or MC selector siya. maganda yung gimmick ng Trio kasi independent yung Left and Right channels, kaso nga lang ang speaker eh (off, A, B) walang (A+B).

kailangan ko tulong niyo dito. hirap na ako. hehe



Title: Re:Surplus amps
Post by: akyatbundok on Sep 25, 2003 at 08:49 PM
nako hirap pumili dyan sa choices mo ser, ganyan din ako dati kaya naparami eh hehe.  tama si doc nirvblakr pag may dala kang speaker mas madali ma narrow down ang choices.  kung ang gagamitin mong pang demo ay yung mga refrigerator-size speakers dun, ibang-iba ang tunog.

during demo try to turn the volume & tone control knobs.  if its really dirty/rusty you'll hear static in the speakers.

kung pang turntable etong onkyo 5 options sa cartridge:

(http://203.131.66.146:8080/integra1.jpg)

characteristic nito is bright and powerful/aggressive, so it goes better with my friend's laid back wharf diamond than my bright mordaunts.

i have a sony 333ES, the sound characteristic is: tight bass & laid back treble so its a good match if your speakers are too bright.. but not a good match if you have a laid back tweeter like wharf diamond.

Another word of advise:

Do not be deceived by looks na kung makinis eh maganda tumunog.  Sometimes yung mukhang bulok eh yun pa ang maganda tumunog.

fakelondongenius-  I have not auditioned the Trio that you've mentioned but I had a Denon jap surplus stereo amp before and warm and "mataba" tumunog.  A very good and powerful amp.   ;D

bata pa ako nung nag start ako maging vinyl junkie, mga grade six siguro. tambayan namin ng kuya ko sa MCS and Quiapo, dun kami bumibili ng plaka.

set up namin nun eh Pioneer SA-V700 135W na amp, Kenwood GE-100IIB equalizer and Pioneer PL-512 turntable. lahat yan eh bili sa pier except our Micro Speakers, hehe. wala pang nasisira diyan mula noon.

ngayun yung amp and eq eh ginagamit ko na para sa home theater, the speakers were replace with mordaunt- shorts. panalo na ako sa 2 channels. tutal may gimmick ako sa speakers eh, kwento ko sayo next time.

tapos naka arbor ako ng isa pang turntable, BSR 20BP. lusaw na yung belt kaya bibili pa ako sa raon (thanks to Hyperaudio).

yes! i'll be glad to try your amps pero huwag muna ngayun. baka mabago ang budget eh, mapabili pa ako ng Integra okaya yung ES. patay tayo diyan! ;D

Title: Re:Surplus amps
Post by: akyatbundok on Sep 27, 2003 at 09:07 PM
good luck bro, test mo mabuti para wag masayang ang pera.  i bought my sony ES from the same store.  the exterior of the amp was in good condition as you can see in the pic.  they even brushed it with some kind of tire black to make it shine.

as doc nirvblakr said, don't just look at the exterior.

(http://203.131.66.146:8080/sony0.jpg)

problems i encountered with this unit:

1)  the interior was very dirty.  when i got it home and opened it, it was so dang dirty... ubo ubo!... the dust was so thick i couldn't see the parts.  im amazed it was even working, but with so much dust i got worried it could short circuit so i cleaned it with a brush.  the pic below is the result.  the transformer cover is so badly corroded that i couldn't take off the yellowish discoloration.  anyway, i thought whoever owned it or kept it didn't take good care of it.

2)  the input selector fell off after a few days... bummer, i was using that to A/B test my X10-D.  since i had 2 audio outs in my dvd player, i can connect the X10-D to the CD in and then directly connect the player to AUX.  switching between CD and AUX inputs allowed me to easily gauge the effect of the X10-D.  luckily, i had the right size allen wrench to screw it back on.  took me a while to figure it out though.

3)  the headphone jack is so rusty i couldn't use my headphones with it (unlike the onkyo).  all i hear is static.  gotta get me a contact cleaner soon.

(http://203.131.66.146:8080/sony1.jpg)

the good part:

1)  ...is that it seems to have all the parts intact.  i've seen a picture of its interior, so the first thing i checked was the transformer and the 4 capacitors.  the capacitors are labelled "nichicon negative black" just like the onkyo integra.  its covered by some kind of fiber glass panel that is held by thick cylindrical rubber.  beats the heck out of me why sony did that.

2)  i also checked the mosfets and counted 8 medium sized and 4 small ones, for a total of 12.  the onkyo had 4 large ones labelled with the "sanken" brand.  FETs are usually attached to the heat sink with some kind of thermal compound that leaves a white residue around it.

(http://203.131.66.146:8080/sony2.jpg)

3)  it produces loads of tight basssss... at 11pm a few days ago i got a call from the guard in our building -- the people who live one floor above my unit complained of the "noise".  they shouldn't be hearing anything coz the floors are all cement & marble.

4)  it also sounds very refined for such a big amp.  the treble is exactly the opposite of the onkyo, kinda rolled off at the extreme highs, making metal tweeters sound less harsh.

5)  BUT.... this is not an amp for warm sounding speakers -- it will sound very dull!  wharf diamond & AE owners stay away from this amp.  they make my mordaunt declaration speakers sound a bit like a wharfedale diamond by rolling off the highs.  this is not a bad thing, since a lot of people prefer the sound of a wharf to a mordaunt.  but do take this into consideration: "warm" by itself is truly satisfying, but warm + warm = dull.

While I await for the coming of my tube amp, i decided to get an amplifier in pier yesterday to complete my audio set-up in the mean time. I got a Marantz PM-54D 120watts. Price: P 3,100.00 (w/ transformer).

They do if you want, siyempre at addl price (normally 500). As to your previous question, some amp in pier has jumper at the back for pre-out/main-in. Tis means you can use them as separate amps. One of the amp still in pier is one of the famous marantz quartet-A technology - PM-74D model (about P4000) which is similar to Yamaha MX-1 in low-impedance capability. Di ko na kinuha because I like the NEC-A10II.

i was asking for NEC amp but the store didnt have one. Instead I saw a marantz PM54D and bought it. I didnt see this post and the post of akyatbundok regarding some stores selling amps and players. I thought the first store with lots of speakers is the only amp store that exists in pier. Had i known of these posts, i would have scouted for more and would have gotten the PM74D instead. The PM54D sounds great too. Anyway, I didnt need much power as it drives a pair of 93db klipsch speakers.

pwede pabuksan pre. the pics i posted are not the actual pictures of the marantz amp. I just got those pics in the internet. some units are really dirty but some are not.

i got mine a lot less dirty compared to other units. :)

i went back to the store where i got my amp and had it replaced. i encountered unbalanced power output and distortion problem with the marantz pm-54d. no replacement can be had so i got the PM-54 version which is of higher wattage (200W). I got the later unit for 4.5k including transformer. Aside from having ridded the issues in the defective unit, the  amp i got has better sound (warmer) and i was really amazed with its wide soundstage. the bass is impressively tight. ;D

oh boy! i hope my "tube amp to be" can out shine this gem that i got.  ;D
Title: Re:Surplus amps
Post by: akyatbundok on Oct 05, 2003 at 11:30 AM
julsp168, congrats!  kasama pa transformer.  been looking for a marantz too but they dont seem to stay too long in the shelves.  mukhang ok yan pm-x4 series ng marantz, they have auto-class A operation w/c is very unique among the integrated amps out there.  ;D

i noticed sa buy&sell newspaper someone's selling luxman "tube" amps daw for 15k.  i called up the guy and found its not really a pure tube amp, but the same hybrid LV-103 i got for 4k at the pier.  sold out na daw siya he sold 3 units already with more to come.  isip ko tuloy ang laki naman magpatong ni manong.  in fairness sabi naman niya its not surplus but somebody's bringing it home for him straight from japan.  personally if that were my budget why go surplus?  you can get a NAD 320bee may remote pa, pre-outs/main-ins and best of all its bnew.

i got to talk to one of the sellers at the pier; sabi niya all the surplus stuff comes in one huge container and there are people who pick off the good units ala bidding.  anybody has a contact there so those interested could participate in the bidding and probably get better units & bargains?  at least yun wala na patong.
Title: Re:Surplus amps
Post by: Audioboy on Oct 06, 2003 at 10:26 AM
thanks akyat.

the Marantz PM-54 has an automatic voltage shift power supply (AVSS) circuit that increases the supply on the output transistors during brief high-level transients and restores the normal operating voltage when the extra power is no longer needed. It has a rated power of 60 RMS watts per channel @ 8 ohms, 0.015 % distortion. The back of the amp indicates a 200 watts of power, thus an indication that the amp has enough reserve power when called upon to pump higher levels.

Post by: akyatbundok on Oct 06, 2003 at 03:30 PM
oks nga yung PM-74D according to the review mga sir.  ang nakita ko pala sa pier dati ay PM-75, yung modelo na hindi class-A.

i was able to audition the PM-80 yesterday in makati but this one was not a surplus unit so it costs twice (8k) but the exterior is smooth walang scratches.  it sounds awesome, mataba tumunog yet detailed.  guess what, i compared it to the 30-yr old accuphase E-202 and for our taste the marantz was slightly better.  hmmm... didn't expect that at all, maybe the accuphase needed cleanup?

i think the PM-x4 line is even better because of the automatic switching.  the PM-80 has a manual switch to toggle between class-A and class-AB but i suspect it has no automatic switching.  i noticed that while class-A mode is very sweet, class-AB seems to be more dynamic (or just louder? i cant tell).  so with automatic switching you get the best of both worlds.

but i came home empty-handed because the last we auditioned was a custom tube preamp + hafler power amp combo that sounded even better than the PM-80.  had to defer any buying decision coz i have to think this through.  of course logic sets in, and my practical side takes over... now i'm thinking: it better sound good the combo costs 28k combined and its not even bnew.  is the hybrid separates worth 20k more than the class-A marantz?  the marantz came pretty close in terms of sonics.  is the pre-owned marantz worth 4k more than the surplus marantz?  hmm... gotta think... gotta think.  best buy pa rin yung surplus PM-74D if its still working flawlessly.

if the amp is in good condition, budget and performance wise, this is the best option. ;D

to the guys who bought these amps, have you considered rewinding the power transformer to our local voltage? i am refering to those amps that are 100volts ac and do not have a facility for changing the input voltage? reason i asked is that i am afraid of "murphy's law" which could very well be at work here....
Title: Re:Surplus amps
Post by: akyatbundok on Oct 11, 2003 at 06:21 PM
sir joan2, pwede pala gawin yun?  akala ko noon pinapalitan nila ang transformer at ibang parts para maging 220v.  kung pina-rewind magbabago ba ang performance ng amp?  sa ngayon kasi im using a stepdown transformer kaya sinasabihan ko mga tao wag basta mag insert sa wall socket.

nga pala, matanong ko na rin... dun kasi sa sira kong amp, ayaw mag-click nung delay switch.  ibig sabihin ba nun ang may sira lang ay yung delay switch?  meron pa kayang pwedeng maging sira sa parts nun?  meron siyang diagnostic LED sa loob for left & right channels.  yung sa left channel nagbli-blink.  pansin ko bago masira yun may scratching sound sa left channel.  ano po kaya cause nun?
Title: Re:Surplus amps
Post by: joan2 on Oct 11, 2003 at 09:38 PM
rewinding the power transformer should not in anyway change the performance of your amp. what it 'l do is to ensure that you don't get into accidental plugging to the wall without the transformer, it should even improve performance because you are getting rid of a device that on its own introduces losses too..
with regards to your relay question, that may very well mean that you have a large dc offset at your output terminals that can fry your speaker in an instant...the relay was there to protect your speaker from dc current and from turn-on and turn-off thumps that may occur had the relay not been there!!! a blown out output transistor could be the culprit...

i turned on my integrated amp to warm up the tubes in my luxman.  im so clumsy, i forgot that i had previously removed the speaker cables from my speaker.  i was just putting down the phone when i saw the speaker cable on the floor, with the banana terminals touching each other!!

"anything that can go wrong will go wrong" -- i lost the right channel.. hu hu hu  :-[

ive always been careless about these things bcoz of the circuit protection in newer amps.  its the 2nd luxman hybrid in a row that ive clobbered.  i felt so bad, i only had one thing in mind: in my next trip to my favorite shopping mall ("The Pier")... i'll get me one of those big killer amps.

Post by: akyatbundok on Oct 13, 2003 at 12:33 PM
iceman, i got the sansui AU-alpha707.  pang palubag loob dahil nakasira nanaman ako nung luxman.  i'm very happy with this amp; i took pictures of it last night, will post later.

based on the sansui.us website, you should avoid models made in the early 80's because that's when the company had labor and currency exchange problems.  true enough, those models na may suffix na F at G ay naiipon lang sa pier.  i got one of the alpha series which was the company's attempt at regaining market share to make up for the poor models.  the website said that the X and alpha models were manufactured at a loss.  you will immediately notice the difference in quality of the parts.

i got this in the store with the stacked speakers.  before we tested the unit, i asked them to open up the casing.  this one has the biggest EI transformer and capacitors that ive ever seen.  bigger than the sony ES i got from the same store.  the 2 caps were almost the size of beer cans!!  :o  i checked the AU-707X model in another store.  that one had a huge toroidal transformer and 4 smaller caps.  but unfortunately it was defective (i never buy without auditioning it).

the sound has a very good balance -- slightly weightier bass than the sony ES/kenwood THX and some shades of the refinement of the Luxman hybrid.  the luxman is my favorite amp because the background is so quiet and the sound is so clean/clear.  the sansui approaches the luxman's clarity but adds the bass weight that's missing in the luxman.  this is just my initial impression, so it could still change after i do more listening.  i always get excited when i get something new.

akyat,

balak ko ngang kunin yan 3 weeks ago eh kasi it is about 130Wpc (8ohms) and 160Wpc (6 ohms), pero nagpigil na lang muna ako. Kung dalawa yang 707 na yan noon, could have purchased both, kasi meron yang main-in (parang separate amp baga), saka kundi ako nagkakamali, may XLR input pa yata yan eh.

OK yang amp na yan Bro, pero tyagain kong hintayin ang 907 series, o kaya X111 series, o kaya yung mga reference series. Magkano mo naiskor?
Title: Re:Surplus amps
Post by: akyatbundok on Oct 13, 2003 at 12:47 PM
pre, you're right it has XLR balanced inputs for the power amp.  the build quality is first rate.  onga, if you see the AU-alpha907 go for it!  pero this one cost me dearly: 5.5k... hu hu hu  :-[  mahal siya, but still cheaper than my luxman lv-105... asking price was 6.8k.  sabi nung store, they once had 3 of these.  but gotta avoid the F and the G, they're starting to accumulate in pier.

jofkevski, a friend of mine has a similar idea as yours.  he wants to build his HT using only a dvd player w/ built-in DD/DTS decoder, and then 2 surplus amps plus a sub.  he's gonna phantom the center (we got the idea from av_phile - thanks bro!) with his diamond 8.1 for a very cheap but kick-major-booty 4.1 system.

just wanted to share that this is currently how my HT is set-up:

integrated amp driving the fronts (phantomed center)
sub-woofer connected via speaker line-in (fronts)
aiwa mini-component as surrounds

dvd settings:

amp connected to FL-FR out of my Kebao 3089
center speaker - OFF
sub-woofer - OFF
mini-compo connected to SL-SR out of my Kebao 3089

i cannot find any HTIB's that will match this set-up kaya I'm interested in getting a surplus amp and another pair of speakers so i can get rid of my mini-compo (nakaka sira ng japorms)  ;D

Title: Re:Surplus amps
Post by: jofkevski on Oct 13, 2003 at 02:47 PM
actually I have different intention. I need amp that has main-in (bypass pre-amp) sa surplus amp. I initially looked with the guy that has A-10III (similar to my A-10II) except his has 240VA trans x2 while mine has 190VA trans x 2, while all others are the same (hirap ngang kausap yung tao). Thus this amp will be functioning like separates.

Then I will keep my Yamaha RX-V630 and will use its pre-out (L, R, surrounds no center). 8.1 are all my surrounds.

Am currently using alpha607 of sansui to drive my 2-coil 12-inch DIY subwoofer, each coil has each L/R channel of the sansui 607. I used the SW pre-out of RX-v630  to feed to this 607. so each coil may receive 100Wpc, for a total of 200W for my SW driver.

Having 707 or 907 (alpha series) will maintain the looks of all the amps (piano finish). Presto, I will then have HT build on good separates, that will cost thousands of dollars using brand new gears.

jofkevski ,
if you are planning that route, i suggest that you use the same model power amps, reason is that with the same amps, the gain of the amps will be identical, so that balancing will be easier than using dissimilar ones...just my 2 cents...

Thanks for the reminder. This is the reason why I have to tag 2 identical integrateds (which can function as a separte) to buy in pier - to maintain gain and amp signature on sound.

yes, that is why gainclones are becoming popular, you can rig up a five channel amp on the same chassis....

joan2, added a discussion above re supertweaking of amps like sakura.  care to share some thoughts on how to go about it? salamat!
Title: Re:Surplus amps
Post by: joan2 on Oct 15, 2003 at 06:34 AM
any amplifier for that matter can be tweaked this way:
1. electrolytic caps in the signal path can be replaced by teflon, polypropylene or polycarbonate caps, in that order, mylars(polyethelyne) are a no-no.
2. bypass electrolylitic caps may can be shunted by films as i have mentioned in 1.
3. mica/creamic caps can be replaced with polystyrene caps..
4. caps used in the power supply can be made bigger, ie, a 4700uf changed to 10000, lower esr can be achieved by parralelling smaller caps than by just a single big cap. these caps can also be shunted by caps i mentioned in 1
5. the power transformer can be changed to one with a higher va rating, but of the same voltages..
6. power supply rectifiers can be changed to fast rectifiers or even schottky ones....
these are just starters, there are more....

those owning units with 100volts ac, this is the opportunity to change your transformers to higher va rating and with 220volts primary....

subwoofers with cut-off frequency below 120 hz is non-directional, kung hinde kalakihan ang listening room mo, you can do with just one, placement is also non-critical, you can make a center table out of your sub-woofer...subwoofers require a lot more power than mid and highs, so you can bridge one amp to make it a subwoofer amp and another amp for the mid/highs...be sure to get identical amps to get your balancing easy and avoid guesswork....

kung pang turntable etong onkyo 5 options sa cartridge:

(http://203.131.66.146:8080/integra1.jpg)

characteristic nito is bright and powerful/aggressive, so it goes better with my friend's laid back wharf diamond than my bright mordaunts.

i have a sony 333ES, the sound characteristic is: tight bass & laid back treble so its a good match if your speakers are too bright.. but not a good match if you have a laid back tweeter like wharf diamond.

akyatbundok,

sir, i found an onkyo integra A-819GTR for sale here in our place and would like to know if you consider this a good amp if i wanted a separate setup for my audio? plan to buy monitor audio B2s as my speakers. thanks!

Title: Re:Surplus amps
Post by: akyatbundok on Oct 20, 2003 at 04:09 PM
cousin skeeter, this is a breakdown of the Onkyo Integra releases:

GT --> GTR('82) --> RS --> RX('84) --> XX --> EX('88) --> XD('89)

the GTR was released in 1982, the RS was released immediately after, probably in 1983.  i dunno how the GTR performs but im familiar with the RS.

my impressions of the RS... extended high highs & low lows but a bit lean on the mids.  with a metal tweeter like MA and MS, it could sound aggressive with poor recordings.  when i turn on the "softness", the sound smoothens without changing the tonal balance.  i found this to be a good match with a rolled off tweeter like my previous AE speakers, but with a bright speaker.. i dunno.

i think its best if you listen to it yourself.  pm me for audition pre, saan loc mo?  im in ortigas.  im also curious about the B2 for an audio setup, how about a deal -- if you have a friend who has a B2, bring it over and let's check if it's a good match.  you can also listen to a sony ES and a sansui for comparison... deal?   ;D   ;D

Title: Re:Surplus amps
Post by: akyatbundok on Oct 20, 2003 at 04:54 PM
ahh... magkano benta sa inyo?  siguro sa pier it would be around 4k... i think the B2 may have similar characteristics in the treble as my MS-908.  matagal ko na hinde nagamit yung onkyo A-819RS eh so baka nakalimutan ko na tunog nun.  pakinggan ko nga ulit and i'll post my impressions tomorrow.  it was my first surplus amp that changed my plans bcoz i was so satisfied with it driving my previous speakers.  for the price i got it (3.5k), i can't complain.  original plan was just to use it as headphone amp but eventually it became my main amp pushing aside my receiver for audio use.
Title: Re:Surplus amps

Post by: akyatbundok on Oct 20, 2003 at 06:13 PM
hmmm... same price i got for the sansui.  pwede pa siguro tawaran.  alam mo tawag nila sa surplus?
"ji-ya-n-ku" --> junk.  hehe... wait till you hear what they call a "stewardess".

original bnew price in japan gives you an idea where it is positioned in the market, whether budget/mid/hi-end.  entry-level amps go for 40k yen... the onkyo is 105watts per channel at 80k yen.  the sansui is 130wpc and went for 128k yen.  top models can cost from 200k to 450k yen when bnew.

Note: current exchange rate... 1 peso = 2 yen.
Title: Re:Surplus amps
Post by: akyatbundok on Oct 21, 2003 at 11:27 AM
cousin skeeter,

I connected the onkyo integra and listened to it all night.  I even watched bulletproof monk with it in my continuing "movies on 2ch" experiment.  Its hard to describe how something sounds, because everything is relative to what we're familiar with.  I hope this helps but i've listed down the relative tonal balance of all the amps i've used, using my mordaunt-short speakers, based on my short recollection of using it.

HIGHS
(Darker) sony -> sansui -> luxman/HT -> onkyo (Brighter)

MIDS
(Lighter) onkyo -> luxman/HT -> sansui/sony (Heavier)

BASS
(Lighter) luxman -> sony/HT -> onkyo/sansui (Heavier)

As you can see, the onkyo has strong highs & lows but slightly recessed mids.  The big surprise is that with different speakers (wharfedale diamond 8.1), the mids aren't recessed at all.  The diamonds have kick-ass mids at the expense of some treble detail so its a good match.  In fact the onkyo+wharfedale combo sounds like sony+mordaunt.  I guess that proves how important component matching could be.

Gear used:
---------------------------------------
luxman - LV-103, LV-105
onkyo - Integra A-819RS
sansui - AU-alpha707
sony - TA-F333ESX
HT - marantz SR-7300 + kenwood KM-X1000

the japanese dump their home grown amps in favor of stateside amps, like mark levinsons, krell's, jeff rowlands and the likes....no such amps  from japan selling at your favorite mall?

and i thought it is only us pinoys that have the touch of colonial mentality....

hey, i did my research on k405/j115, these are toshiba parts, if not available in raon we've got problems....

sir joan2, i haven't seen levinsons or rowlands there yet, but guess what?  i did see a Bose amp (yup, an amp) with a very high asking price.

thanks for the info on the power transistors..  i'll look them up at raon.  i was wondering if its possible to replace the power amp section of the luxman with say the one inside the sony ES?  or maybe pull out the tubed preamp section and then place it in another amp?  that will make it a Frankenstein amp.

pinsan skeeter, i'm not very familiar with the sound of the B2, but i do know it has a metal tweeter like my MS.  i'm curious how it sounds.. does it have strong mids?  i think a speaker with good mids would match the onkyo, but a bright speaker would not match very well.

im planning to get a speaker for my bedroom for pure audio use.. actually ive decided on getting the yamaha ns-1000x mini-refrigerator size speakers, but unfortunately somebody beat me to it.  those are classic speakers that would have been the start of a "surplus speaker" thread (sayang!).  but since i cannot get hold of them, i might consider the MA B2+stands or MS-914.  meron pa bang ibang alternatives for 15k?

my dream is to have a big speaker like this diatone (http://www.niji.or.jp/home/k-nisi/ds-10000.htm) or this yamaha (http://k-nisi.hp.infoseek.co.jp/nsx-10000.html)

im game for the frankenstein amp idea... i'll look for the mosfets this weekend, and if i can't find them, i'll bring it for surgery.  ;D

i read up on the leach amp; seems like a bullseye matchup.  looking at the luxman's internal parts, it would seem that the power supply isn't as hefty & powerful as the other amps, which may account for the lackluster bass performance.  but its strength is in clarity, refinement & detail.  if i can keep this refinement and add the sony's tight/muscular bass, i would be very happy with this amp.

will post internal pics so you can formulate a strategy.  thanks sensei!
Title: Re:Surplus amp internals
Post by: akyatbundok on Oct 21, 2003 at 06:57 PM
joan2, these are the internal pics of the luxman & sony amps.

1. tube preamp - the tubes are contained in a removable housing
(http://203.131.66.146:8080/frank1.jpg)

2. luxman internal pic - Behind the tube housing is a small circuit board with wires connecting all over the place.  Circuit boards appear to be easily removable.  Beside the main power transformer are 2 smaller ones that are probably used by the preamp.  You can see the mosfets screwed to the back of the heatsink - 1 black and 1 green per channel.
(http://203.131.66.146:8080/frank2.jpg)

3. sony internal pic - There seem to be enough space around the power transformer to place the tube preamp section of the luxman.  I wonder if this is possible?  Nothing definite yet, just thinking of the possibilities.  I'm starting to feel hesitant about sacrificing the sony to get the luxman to work.  Best case is still to find the right mosfets and get the luxman working like new.  I found somebody who is in the same predicament with the same luxman model; he may be my best chance of finding the mosfets.

joan2, the tubes on the luxman are marked with:

Alpine/Luxman
6FQ7 6CG7 USA
(http://203.131.66.146:8080/tube1.jpg)

the 2 filter caps are labelled "ELNA 71V 10,000uF".

on the sony there are 4 caps labelled "Nichicon negative black" - 2 are smaller then the other 2.  i wasn't able to write down the specs but in the niji website it says the Class A step has a total of 13,400uF and the power step has a total of 25,000uF.

I took out the tube housing on the luxman to confirm if they did separate the tube preamp section.  No they didn't - the tubes are directly wired to the main board.  I guess when they mean "integrated amp", they really mean it.  The small PCB's behind the tube housing are just for the tone controls and the pre-heating.  You're right about the compromises that manufacturers have to make - not all design decisions are based on optimizing the layout.  The tubes may have been placed on the faceplate just so that users can see them.  Long cables connect the pins to the mainboard, so they might as well could have just placed the tube socket on the mainboard.

tryaudio, yeah me too thanks!  right now its still doing a good job as my current headphone amp.

Akyat,

Just became curious reading that word "ELNA" from your post.
Is that a manufacturer of components for amps?

Because I read from a new line of Receiver from a Certain Brand saying "equipped with ELNA CHEMICAL CONDENSER" what's that about?
Title: Re:Surplus amps
Post by: joan2 on Oct 23, 2003 at 02:30 PM
"ELNA" ,Rubycon, Nichicon, Omats, Panasonic, are brand names of electrolytic capacitors used with ss amps....

akyat,
yes, the tubes are medium mu twin triodes, we'll know for sure what they are there for when i got a chance to look at it.....

as promised, here is a simple tweak for those surplus amps rated for 100volts ac, just wire in an MOV (metal oxide varistors) rated for 120 volts ac accross the ac line, right after the fuse, and before the power on switch
so that in the event the unit is plugged into the 220volt outlet without the stepdown transformer, the fuse will blow, even beofre you turn on the unit. it will be much easier to replace fuses than have your unit repaired, as we all know, replacement parts for those units are hard to come by as many of them are no longer in production. as a bonus, the mov's will also act as hash and transient spikes suppressor since they can absord short duration line garbage!!! these mov's are no bigger that a 25centavo coin and comes with two leads...haven't checked availability at raon, cause i ussually get mine from surplus equipment.....

How can i safely use my 110-120vac wall outlet to power a future surplus amp rated at 100v only? Thanks.

depends on your japanese unit, the rails go up as the ac line voltage go up, i will be bold  use it but only after i have examined the insides of the amps and find out how much the capacitors can withstand a higher voltage, 110 volts should be fine but at 120, you are on the brink already....

I just came from the pier shopping mall.. nothing much to excite the SARS syndrome, except.. something that i've been contemplating for a long time - surplus speakers!!  Ive always wanted to have an all-junk setup, but the weak link has always been the speakers.  There are some really bad sounding speakers over there.  When i read about 45mm's Yamaha ns-1000, i realized that its possible for an all-junk audio setup to beat the pants out of an all-new audio setup.  So im thinking of putting up a combo that will beat my very own MS Declaration flagship speakers.  Is it possible?  We'll see... i saw a couple of paper-coned 70's mini-refs.  Nahhh... they sound awful.  There's a couple of Victor speakers that look nice.  Victor (JVC) has a pretty good history in Japan.  If i find one with the word "Spirit" etched on the front baffle, i would get excited.  But not today... there were only entry level stuff.  Then i saw an Onkyo in pretty bad condition.  The word "Scepter" would have been the equivalent magic word for the Onkyo brand, but i haven't seen one yet.  Oh well... no fish today.

hey sir joan2, thanks for the tip.  i was also at raon yesterday looking for the K405/J115 mosfets.  i did find the replacement you mentioned.  the IRF640 costs only P40... its a good sign for my luxman.  ;D  ;D

i have a question.  this probably belongs to the ss thread, but it concerns surplus amps too.

do amplifier parts degrade over time?  if yes, does it affect the sound?

akyat,
over time, dust accumulates on our amps, so this makes our amps a bit hotter, then the capacitors dry up, so this has an effect, loss of volume.....replacing them can restore an ailing amp back to health....cleaning also helps....you have to find the irf9640, its a p-channel type...irf640 can be used to make zen amps.....
Title: Re:Surplus amps
Post by: akyatbundok on Oct 27, 2003 at 05:02 PM
sir joan2, ok i'll go look for the irf9640... the supplier that had the irf640 did not have it.

i also got confirmation from my friend's supplier that the luxman's 2SK405 and 2SJ115 are already discontinued.  the replacement products are the 2SK1529 and the 2SJ200 also from Toshiba.  he sent me the spec sheets in PDF format.

the only problem is: i dont think my friend could order just the 8 pcs i need for 2 amps.. when they order parts, they order in the million pcs (its a manufacturing plant).

Post by: joan2 on Oct 27, 2003 at 06:45 PM
akyat,
can you post the link for the replacements, i want to look at the specs...if available, better that we use this...can he ask for samples? onsemi, ti and national have sample programs, maybe toshiba has too.....
Title: Re:Surplus amps
Post by: akyatbundok on Oct 27, 2003 at 07:08 PM
joan2, here are the spec sheets:

>> 2SK1529.pdf (http://203.131.66.146:8080/2SK1529.pdf)

>> 2SJ200.pdf (http://203.131.66.146:8080/2SJ200.pdf)

thought so... the 2SK405/2SJ115 power mosfets are used in both the luxman hybrids and the sansui MOS limited/premium models.

joan2, according to my friend, toshiba is a bit strict when it comes to their sample program -- too many questions... i assume his contact works in toshiba japan coz his email address is @toshiba.co.jp... but we did get contact info on 2 of their distributors here in manila.

i'll email you the contact info tomorrow.  call you later.

Re: Mini-ref type speakers

Ano ba ang usual characteristic ng sound ng speakers na ganito?   Used to have a pair in my very small bedroom (from 1993 to 2000) Pioneer ang brand paired with my nikko 9095 amp.  Medyo dark-sounding ang speakers na ito.  I used to turn up the treble control (sagad) just to be able to make the sound more balanced.   Sa bass department naman, wala talaga akong masabi sa combination ng amp and speakers, deep and strong ang bass.  In music mode with my current HT setup (w/ subwoofer on),  di nya maipalabas yung ibang lower frequencies sa mga cd tracks/songs na pinapakinggan ko dati.   One such song is "A Whole New World" from the Aladdin Soundtrack.  Also listened a lot to heavy metal and alternative cds.  I listened a lot to songs of groups such as Metallica, Skid Row, Tesla, Dream Theater, Pearl Jam, Stone Temple Pilots, Saigon Kick, Trixter, etc.  Medyo rocker talaga ako dati dahil mahilig din ako mag-gitara ;D  I'm not saying that my current setup is a slouch, I mean its really great for HT.  Pero iba pa rin yata talaga kung meron kang dedicated na 2-channel/stereo setup. :D

OT: I went back to "the mall" to buy a pair of kenwood mini-ref speakers that i saw last week, only to find that it was sold already... curses, foiled again!

Unlike most speakers at the pier, that one looked like it was "pre-owned" rather than uhh thrown away as junk.  But the downside was they also priced it way above normal.. 5.5k would you believe?  I could get a Diamond 8.x with that.  Anyway, i thought it was too expensive, but (again) got curious when i saw it at yahoo auctions selling for 68k yen.  Sure its cheaper than the yamaha's 80k, but 68k yen that's about 30k pesos.  Plus it looks just like my very first speaker, a bookshelf kenwood the size of a B&W602 with the same familiar metal tweeter and cross-weaved carbon fiber woofer.  The only difference i think is that the midrange is a large metal dome just like the yamaha, and its 3x bigger than my bookshelf.  So i thought why not check it out... armed with my audio CD's and 5.5k, i went home empty-handed.  Which i guess... is ok!   ;D  ;D

sighted several weeks ago... but i dunno if still der...

click here --> Denon PMA-780D (http://www.niji.or.jp/home/k-nisi/pma-780d.htm)

- 8ohms: 110w + 110w continuous
- 6ohms: 130w + 130w continuous
- 2ohms: 350w + 350w dynamic
- DAC S/N: 105db

this unit has built-in DACs... 3 coaxial inputs at the back.  we tested it with 2 pairs of mini-ref speakers coz one pair had busted woofers and the other pair had busted tweeters.  so it was like we were bi-wiring a single speaker.  sound was earth-shaking loud at 9'oclock volume.  the woofer speaker had 12 inchers so i could feel the slam in my chest.  sorry guys, i was contemplating on this so i didnt post it right away.  but now that i'm broke, i stopped contemplating... ;D  ;D

its hidden inside the store.  i specifically asked "manong" to keep it in his internal stash of amps coz i might get back to it later, but that was weeks ago.

yung napagusapan natin ha, ang style ng pagbili dun ay wag agad babanggitin ang brand at modelo na hanap niyo.  baka tumaas presyo eh.  mawawala ang element of surprise hehe.  binabasa din nila ang kilos natin.  minsan tinataasan yung price kung di mo na maitago na kukunin mo na.  kelangan medyo pa-kyeme muna, "sige tingin lang ako sa kabila".  malas mo lang kung pagbalik mo paalis na ko dala-dala ko na hehehe.

Don't show your enthusiasm when buying one at baka maisip ng mga sellers na atat tayo at baka magkataasan ng price.
Don't also tell them about PinoyDVD. Mahirap na. At baka iyong P4k na price maging 10k or higher pag natunugan nila na patok ang Surplus.

These Surplus Amps are really a steal considering price and performance. Sugal nga lang. Pray na it will not conk out kaagad.

click the pic!

(http://203.131.66.146:8080/sansui.jpg)
 (http://www.pbase.com/akyatbundok/sansui)

things i like:
- glossy finish
- huge transformer
- beer can size capacitors
- isolation of pre/power/terminal sections
- power amp direct/main-inputs
- XLR balanced inputs
- gold plated RCA jacks
- big binding posts
- the big & warm sound!

its been a month since i got the sansui.  i started to write my impressions when i posted the pics last month, but i changed my mind coz i wanted to keep it to myself, lie low muna until i spot the newer & higher model alpha-907i.  baka tumaas ang demand eh, di ko na makuha.

Good decision.  I had a pre-owned  Sansui AUD11 as my first serious integrated amp way back in 1987.  Among the prevalent brands in components locally avaialble in the 70s and 80s like Kenwoods and Pioneers, I much preferred the Sansui both in looks and sounds.  Just wish I had kept it together with other stuff like turntables and LPs.

Oh dont despair now! It is just 120watts/channel. THD 0.005%
weighs 17.5kg, 600watts power consumption, 150W damping factor into 8 ohms. freq response DC-300khZ 0,-3dB.

You can buy it again!!! . . . . . what???

Yes, you can buy it again.

AU-D11 is the international release of japanese AU-D907F (circa 1980). So get one for yourself in pier - PHP 5,500.

j_albert22, pictures of the different models can be found in the sansui.us website.  i saw the rear pics of the alpha507i and d707g there... it seems they dont have power amp direct inputs so you cannot use them as a power amp for your receiver.  but if your intent is for a separate stereo amp for music, the specs will be your guide.  the alpha507i is kinda lightweight at 7.4kg.  i couldnt find specs but i would estimate it to be between 60-80watts/ch.  the 707's are usually 100watts/ch and above, which is my preferred power output.

Here we go again...

Can you please explain to me why buying 3 surplus unwarranted amplifiers (even if it is highly rated) would be better off than buying a spanking brand new 6.1 receiver with all the latest technology and warranty to boot.

I can understand it if you have 3 amps lying around and you are just making do with the situation.  But to spend the same amount of money that can buy you a brand new one seems incredulous.  I'm stumped.  But hey, I'm open minded.  I'm willing to listen.  I might have missed something here.

No offense meant.  But I hope the newbies discern when they are being taken for a ride. >:(

well, take it from me, i've tried it (partially anyway)... adjusting the volume is a pain!!  say for example i'm in the middle of a movie and my sister asks me a question.  i turn down the volume of the fronts first, and only the front effects go away, so the dialogue is still interfering with our conversation.  then i turn down the center.  now i hear all bass from the subwoofer.  i tell myself forget the bass... what were you asking?  - do you want meat lover's or super supreme? ... arrrgggh!!  now i have to run the speaker setup again...  how many interruptions happen in one movie?  5x = PAIN...

but if you already have a receiver and your intent is to give your front 2 channels additional muscle by using the power amp section of your integrated amp (assuming it has power amp inputs), then a surplus is an economical way of doing it.  just be aware that this is JUNK were talking about.  as long as you understand what it is... you get it as-is so you can either choose to make a gamble, or save up for a bnew unit.

I was just thinking out loud.  I figured the surplus price is so cheap, getting three wouldn't hurt that bad.  The cheapest Rotel 6-ch amp cost 30T with only 60 watts RMS per  sharing one toroid . Those 3 surplus integrateds might cost only around 16T altogether.  I would then have 3 separate power supplies powering 6 chanels.

And besides, if ever, i will bypass all their preamps via the pre-main jack at the back, as I already have a Rotel pre/pro to control the signals.  Actually, what I am interested in are surplus power amps.  But integrateds with bypassable preamps will do if dirt cheap.  

Then again, still thinking out loud.

Hi Voj,

Pls see my response to Levi.  

Just to reiterate, I am interested in surplus power amps.  In earlier inquiring posts, apparently there are none. Only integrateds.   But integrateds where I can bypass that preamp section will do if dirt cheap.  Am into separates. Not interested in receivers.   But i don't mind getting bargains when they present themselves.

Taking people for a ride???  I don't recall advising anyone to take this route.  It's a complex route.  This is only me taking the ride if at all. I just reacted from a response that said such an integrated as I had in the past is available at the pier.  I said with the price of 5T or so, i'd take three anytime.  But I'd appreciate if you can suggest a 100 watt/ch 6-channel power amp for about 16T or 17T.  Thanks.

well, take it from me, i've tried it (partially anyway)... adjusting the volume is a pain!!  say for example i'm in the middle of a movie and my sister asks me a question.  i turn down the volume of the fronts first, and only the front effects go away, so the dialogue is still interfering with our conversation.  then i turn down the center.  now i hear all bass from the subwoofer.  i tell myself forget the bass... what were you asking?  - do you want meat lover's or super supreme? ... arrrgggh!!  now i have to run the speaker setup again...  how many interruptions happen in one movie?  5x = PAIN...

but if you already have a receiver and your intent is to give your front 2 channels additional muscle by using the power amp section of your integrated amp (assuming it has power amp inputs), then a surplus is an economical way of doing it.  just be aware that this is JUNK were talking about.  as long as you understand what it is... you get it as-is so you can either choose to make a gamble, or save up for a bnew unit.

Yup, I realize the risk.  But like I said, am just thinking out loud.  The possibliities out there are many.  Surplus integrated or amps are an option for me.  Have yet to visit the piers if such amps are inded available as mentioned here.  And if i do get some nasty junks, I'd fall back to what little electrojics I know, confident that there are people in this forum I can rely on for needed assitance if i need some.

Yes, I agree. It takes a little creativity to overcome what seems to be a challenge. If I will build a cheap but using good branded amplifier, this I will do

purchase a generic DVD player like kebao that has DTS (3,200)
purchase 3 japanese branded amplifier in pier (say Sansui alpha507i at 2,500 each)
purchase a subwoofer amplifier (say sansui alpha 607i at 4,000)

The first amp will have my front and rear left channels
The second amp will have my front and rear right channels
The third amp will have my center channel
the fourth amp (607i) to have the SW input

Since they are identical amplifier, the gain is identical for all of them. So, I adjust all of them at 12 o'clock position. The subwoofer control maybe at different setting. Volume control of everybody will be from DVD player.

Your equivalent AVR is only 7,500. This is a highend system, even though they are surplus. And can compete head-on with any system below 30k in sonic performance.

pssst j_albert22, test niyo yan ha... siguraduhin niyo hindi yan kamatis!  mura yan sa 2.5k pag amp ang mabili mo pero kung kamatis yan napakamahal na gulay yan!  ;D  ;D

eto checklist ko pag test ng kamatis este amp:

1) open the casing - check for evidence of replaced parts & excessive dirt
2) sound check 1 - set tone controls off then listen... if you dont like the sound don't buy it!
3) sound check 2 - turn it up loud... does it clip or distort?
4) left/right channel - both speakers working?
5) balance check - left and right are same tone & volume?
6) rust check - turn the knobs.. do static come out of the speakers?
7) power cord - is it cut or deformed?  i've had both.. fire hazard!

JOhn,

I am sorry, I can not follow on the description above.

I have a Kebao connected to a surplus amplifier - Yamaha AVR1000. I have a specification of the amplifier somehow, and I noted the sensitivity it needs is much smaller than Kebao output. So I have to somehow lower the output from my kebao DVD. I have a very good and clean sound. Before I bought this surplus amp, I really checked that everything looks and sound alright.

The volume control of Kebao and Nextbase is digital - and as such, it has no output stage (analog stage) which makes up the volume control. The RCA out of these DVDs are not pre-out - it is still the line out at around 40K+ impedance. Connecting this to MAIN input of an amp will really yield a bad sound because it is not enough to feed the power amplifier.

Going back to DVD volume control, I tested this is digital - not analog stage. Connect an AVR to the DVD via optical, play a CD (this will be PCM-2 channel), make volume change on your DVD, your AVR will be able to decode the digital signal as lowering the volume.

Another test I made, if my memory does not fail me, is to test DD and DTS signal via optical connection - reduce volume on the DVD - the AVR will decode this as lowering of volume. I have to re-confirm this tomorrow after I test it tonight.

Based on this experimentation, I think what I posted can still be done with good sound - but it might just be me - but listening to it will still be your final judgment though.
Title: Re:Surplus amps
Post by: john5479 on Nov 14, 2003 at 03:35 PM
I am perfectly aware that the volume control of the dvd player is digital, not analog. still the digital sound info will still be converted to analog through the dacs of the dvd player, which then goes out to the analog outs.

With that being said, when i tried to use the digital volume control of the dvd player the volume increase can be from very faint to loud and i found the sound coming from the analog outs of the dvd player too harsh for my liking.

Its all about preferences, i even tried using just one integrated amplifier and downmixed the channels to stereo, so the digital volume control will not be my volume control but instead control it through the integrated amp....still harsh for my liking. If it sounds ok to you then by all means enjoy your setup :)

when i did this, lowering the volume on my kebao remote does not lower the volume when connected to my avr via digital connections

the kebao 3089 can only send out either analog (via 5.1 rca) or digital (optical or co-ax). selecting either of the two disables the other...

the other day i happened to pass by a shop here in Lagro, QC selling 2nd hand and several brand new korean TVs, vcds and some amps with speakers.

i tested one of the 2nd hand amp for sale--- its a 50 w x 2 DAEWOO and the name of the speakers hooked is lofte... its 70 w each--idont know these brands but it sounded very pleasant to my ears, lalong-lalo na ung speakers, ok at very clear and mids at sa highs nya at ang lakas sin ng bass nya--and it costs only P2500 for the whole set of amp and speakers. Got no money at that time so went back nlang yesterday, pero sayang nakuha na pag-alis ko that day --  :'(

sinabi ko sa manager ihanap ulit ako ng same combination, sana i will happen to see a pair of these again..

Post by: ArnieSwarzie on Nov 21, 2003 at 06:40 PM
I have not retested it on a Kebao because my unit is still out with somebody.

With Nextbase, the setting should be as follows:
  under spdif setting, choose spdif/pcm

with avr connected via optical or coaxial digital, make changes in DVD volume and the AVR will make a corresponding volume change. this mode is PCM in the AVR - digital format - not via the analog out of the DVD.

Also, you can make equalizer changes by selecting pre-set equalization, and also you can have bass boost (2 types) whichever you like.


For the analog outs, the digital implementation is also kinda clean. The DD analog out can be altered by your chosen equalization, and bass boost mode. I think all 5 channels will be altered - and I think digitally as well.


For the Kebao, I will have my unit tonight so I can give you the config for you to test the feature in digital format I mean.
Title: Re:Surplus amps
Post by: ArnieSwarzie on Nov 22, 2003 at 09:54 AM
In Kebao, the AUDIO output should have setting to SPDIF PCM. This is similar to Nextbase. Setting to SPDIF/RAW means you want your AVR to select which coded material to play (DD, DTS, PCM).

For Kebao, with only optical connection to AVR, you can change volume, alter equalization by using preset, or make your own equalization. It has no bass boost like Nextbase - but you can do this via equalization. And this is in PCM implementation - fully digital - not analog - which your AVR can decode.

I have not tested the analog output - but remember tried it before, the equalization is effected on each channel even in DD/DTS decoding. Will feedback if I will be able to do this tonite.

i was at the pier yesterday... saw the 1st multi-ch power amp i've seen at the pier.  the brand/model is NEC AVA-606 -- its a 6-ch power amp with total power consumption of 210W.  i guess that makes it rather low-powered per channel, maybe about 35W/ch.  but all channels can be bridged so it can be configured for 3ch, 4ch, 5ch and 6ch.  i suppose in 3ch mode the power rating would be around 70W/ch.  the casing is aluminum with some very visible scratches in the front panel.

one possible application is bi-amping with 4 channels.  use one 35W channel for the tweeter, then bridge two channels for 70W for the woofer.

or maybe a cheapo setup as described in the previous posts?  i wouldn't know... me, i want my junk to be high-end.  seemed kinda expensive for me at the asking price of 5k.

Nakow! Newest addition to the family ng amps ni Aykat pag nagkataon... ;D

di ko nakita pre, kaya iba nauwi ko... pina-replace ko yung CD player na nabili ko last month ng kenwood surplus speaker.  medyo di pa ka-level ito nung yamaha ns1000 or diatone mini-ref speakers pero for the price ok na rin.

(http://203.131.66.146:8080/kw1.jpg)

first impression... bright... unnatural vocals... needs tone controls or equalizer to correct the timbre.  though it has nice tight bass, it doesn't go very loud.  push the volume and the cabinet resonates.  but once the treble is toned down and the midbass turned up slightly, it gets closer to the right timbre.  after listening to it all night, i found it likes R&B and disco.  in the morning, i played it again and realized that it actually sounds pretty good on vocals too.  very detailed and lively.  then i listened to my b&w again and whoa... now the b&w started to sound dull.  i realize now that ears are like eyes - if you stay in the dark too long a mild ray of light becomes too bright.  but after a while the eyes forget the old environment and adjust to the new environment and now it becomes the new "standard".  that's the same with our ears, i think.  when i switched from AE to MS speakers i though MS was bright and AE was laid back.  then i got a B&W and now i think MS is laid back, B&W is bright.  then i got a surplus speaker and now i think the surplus is bright and B&W is laid back.  going back to adjust my ears to B&W and MS, i think the brits have got the voice right.  then again, how would i know if i haven't heard the singer in person?  haaay basta maganda tumunog sa tenga oks na rin.

hehehe.... baka malapit na!  konting pakinig pa.... di masyado killer ang nakuha ko eh kaya medyo hesitant pa ko mag "surplus speakers" thread.  kung nakuha ko yung yamaha ns-1000x o yung "plasma diamond" na kenwood sigurado meron na ngayon.  ;)  ;D

good day sir akyat,
i was referred to you by hans adriane regarding this kenwood components that i un-earthed  yesterday circa 1970's speakers working well kaso receiver only light and no real power, the speakers at the back say Kenwood KL333D and KL777D. do you know anything about this model?

search kl-333 on this page - owner's impressions (http://www.livejournal.com/users/mfree/2002/10/22/)

i used to own the the LS-11ES (below) which i sold to a friend w/c i regret because i missed their bass slam.

then several weeks ago i saw a bigger version at the pier selling for 6k... i thought it was expensive for a surplus unit, but when i checked yahoo auctions and found that it was selling for 60,000yen i decided to give it a try.... the midrange metal done seemed very similar to the one used in the yamaha ns-1000x.  unfortunately it was gone when i went back.

hey guys,

got myself a sansui au-7700 amp. they were made before the '07' series (e.g. au507, 907, etc.). this was made when japan and international market shared the same models. got this info from the sansui website.

(http://groups.msn.com/_Secure/0RADqAmMTzYXNEDTttRnNxueur3zBIaBKoS*vvMViZsdDJts1Al9n1p8DY6uTY7wKraeRXL!VfjjKKS4!H697fHytfdlVcDphpMtTtcxLLoc/au7700_1.jpg?dc=4675452900410791905)

for an amp almost 30 years old, the sound quality really amazes me. the harshness common to some modern day solid-state amp is absent (to my ears).

Title: Re:onkyo integra comparison
Post by: akyatbundok on Jan 05, 2004 at 03:22 PM
speaker/amp matching matters...

during the holidays, me and my friend swapped our surplus Onkyo Integras to hear how they perform with our speakers.  mine is A-819RS and his is A-817XX... mine is supposed to be higher wattage but his is a newer model by 2yrs... he wanted to test my integra with his Wharfedale Diamond 8.1 coz he feels there's something missing in his speaker's tweeter... true enough, my 819RS was able to give more sparkle in the treble which made it more enjoyable when watching movies.

on to his 817XX matched with my Mordaunts, i was surprised that his onkyo was more musical than mine.  hmmm... maybe we should swap our amps you think??  the 819RS was more detailed in the treble, but the 817XX had more body without giving away the details, which makes it sound very similar to my sansui alpha.  plus it had a neat contrabass feature in the preamp section that allows you to control how soft or how hard you want your bass.

how can 2 amps coming from the same product line sound so different?  i thought mine was a bit bright, and he thought his was a bit dull.  we swapped and kaboom, it was just right!  i also tested his 817XX with the Monitor B2 and it was a great match.

Guys,

Going back to the pictures of the big Kenwood speakers, didn't you notice one thing?

Try to see the arrangement of the mid and the tweeter, di ba kung baga sa sapatos parehong kaliwa o parehong kanan?

I had a similar big Kenwood speaker before (although mukhang mas low end yung sa akin). I had problems with imaging because of the driver placement on the front of the cabinet. All along akala ko parehong left (or right) yung nabili ko yun pala talagang ganon ang Kenwood!

bro ganun din yung nakuha kong surplus kenwood (medyo low end din).  parehong kaliwa!!  as a result, medyo off by 4 inches to the left yung position ng tweeters kaya i had to adjust the speaker position by 2 inches to the right.  slight compromise lang between sound & aesthetics, but i might use it outdoors na lang pang rugged use.

Akyat,

No problem, I can bring back the amp back possibly this weekend so the others can check it out.

Sirs,

I would like to share my experience with this 817 amp at the pier when I saw one paired with a rotel 7 band per channel equalizer and onkyo speakers (those ref sized described by akyat), I was amazed on what this amp can deliver paired with the rotel, from that time on I know that this amp is a winner.

My problem is that on my wharf, the highs are somewhat laidback so I wanted to resort to an equalizer to improved the performance, unfortunately I do not have money at that time to spend for the equa which cost higher than the amp itself at 4.5K. When we returned nabili na daw the whole sets.

When I checked with 819 it is very good for HT because the Highs and Bass are there, but somewhat muffled mids.  Hence I followed the advise of akyat to keep the amp because it is very good for audio setup, what lacks on this amp is the main-in so there is no way we can use other pre-amps.

what can you say about Kenwood's KA-v8500 - Integrated AV surround amplifier? , ok ba to - to be paired with LS-V220 and CRS-177 (Kenwood speakers)?, medyo low budget lang ako para sa amp/ receiver eh kaya surplus muna and future addition ko na lang yung sub.

Please check this link (KA-V8500):
http://page5.auctions.yahoo.co.jp/jp/auction/e32597446


btw, me nakita rin nga pala ako sa Raon na surplus din naKenwood KA-v7700 ata yun if I 'm not mistaken. Selling at 7k.

Post by: av_phile1 on Jan 20, 2004 at 02:44 PM
Am not familiar with that model of kenwood, but surplus equipment really wouldn't rely anynore on the brand but on the integrity of the vendor.  With how they are handled at the pier, i wouldn't be surprised if many jap surplus have been repaired using inferior replacement parts to make them work.  An amp costing 7T today when it used to cost 30T almost 10 years ago at pre 1997 exchange rates may be a good buy but I really can't expect it to work like new as orginally advertised.  But just like you i am tempted to get one if only to know that I now own a unit I used to dream about.   ;D  Ofcourse it should also work.

Surplus CD players thread
 (http://www.pinoydvd.com/yabbse/index.php?board=9;action=display;threadid=13884)

kailangan lang ng ingat pre, since mayroon mechanical moving parts yan na 10-15yrs old... some old models have a lock at the bottom, you must make sure it is locked before you transport it, otherwise the mechanism may become misaligned and it will have difficulty reading CD's.

with 59 transistors, 22 FETs, 24 ICs, and 69 diodes on the Accuphase - that would be so many parts you have to worry about breaking down.
Title: Re:Surplus amps & speakers
Post by: yukon on Feb 11, 2004 at 05:14 PM
IMHO, I'd go for the EL34...

-minimalist/purist (circuitry and aesthetics)
-easier to repair
-not sure but i think it's warm sounding as against the accuphase
-pero di ba despite it being a 60watter mapili pa rin sa speakers yan?...


Title: Re:Surplus amps & speakers

ooppss, i was actually comparing it to the ss amp A_B mentioned... minimalist na sya if we were to compare it to Accuphase diba?

Title: Re:Surplus amps & speakers
Post by: akyatbundok on Feb 11, 2004 at 05:56 PM
thanks for your inputs mga sir!  hmmm baka magmistulang ss vs tube yata, di naman sinasadya hehe its a real decision to be made... been targetting the accuphase since december so i could consolidate all my ss amps into this one representative, and dispose of all the others... that is, if its better than all the others.

and then i heard a tube amp that could be used in both audio and HT... haaaay, life would be so simple if there was only 1 amp... if i dispose all of my beloved amps i would have enough dough to go ask mr. andrew to build monoblocs for me hmmmm.  life is simple, no more changing cables, no more shorted amp, no more busted tweeter.

or maybe better still, have enough patience to acquire both and do an amp shootout... hmmmm it would be easy to sell the accuphase in case i find the tube amp more to my liking... but would it be just as easy to sell the tube amp in case the accuphase wins? hmmmm.

thanks for your inputs mga sir!  hmmm baka magmistulang ss vs tube yata, di naman sinasadya hehe its a real decision to be made... been targetting the accuphase since december so i could consolidate all my ss amps into this one representative, and dispose of all the others... that is, if its better than all the others.

and then i heard a tube amp that could be used in both audio and HT... haaaay, life would be so simple if there was only 1 amp... if i dispose all of my beloved amps i would have enough dough to go ask mr. andrew to build monoblocs for me hmmmm.  life is simple, no more changing cables, no more shorted amp, no more busted tweeter.

or maybe better still, have enough patience to acquire both and do an amp shootout... hmmmm it would be easy to sell the accuphase in case i find the tube amp more to my liking... but would it be just as easy to sell the tube amp in case the accuphase wins? hmmmm.

Well accuphase is a very reputable brand, the only problem with that is if it does break down, will it be easily serviced ??? , that is if it will break down :)  If it matches your system then go for it.

i've read about some accuphase amps lasting 30 years with only the knobs and terminals breaking down, so i suppose they're quite durable... plus the built-in preamp and phono stage could be useful with a turntable, though i could see how those circuits do add to the complexity of the amp... i like the way sansui lays out their integrated amps: the preamp, phono and power section are in separate compartments so they could almost be separates if not for the shared chassis & power supply... accuphase does things differently, they use circuit boards so their amps are like PC's in that sense.

now for the tube amp, just this last month i've heard a scott, a 300b, and a el34 amp... what can i say, its the end of innocence... i've always known that i will get into tubes someday, just not this quickly... your 60wpc amp made it possible to combine audio & HT, its almost as powerful as a THX amp but more musical, very flexible isn't it?

re: accuphase vs. tube amp... i decided to save up for both na lang, but has to be accuphase first since its so much harder to find, it may be my last solid state amp for quite a while... i couldn't resist it after i saw the build quality, for a 15-year old amp it looks newer & more modern than many new amps in the market... looks very similar to my marantz receiver but more classy and more "serious" coz its twice the weight at 24kg.

(http://203.131.66.146:8080/accu1.jpg)

inside it looks alot like narayan's rotel power amp with the big toroidal trafo and the separate L/R power sections... the beer-can caps are the same as my surplus sansui... no need for a power cable replacement as it's quite thick... the preamp and power amps can also be used separately... max power consumption is 830watts.

(http://203.131.66.146:8080/accu2.jpg)

my initial impression of sound quality is that the treble is more detailed but the bass is slightly leaner than the sansui alpha... it doesn't get sibilant though, the treble seemed extended rather than emphasized... bass is also weighty but i think it doesn't hold a candle to the hafler xl280... i have to listen to it a bit more to really know how it sounds, but so far so good.

Mga Boss,
I couldn't help but thinking that we might have deprived akyatbundok's friend of a Home Theater experience. Kasi d ba this forum was started with the fact that he might have wanted a 5ch set up but the wifey wouldn't allow it? This is just an opinion, but I know that a home theater system can offer a great 2 ch experience, but it isn't so true the other way around, d po ba? Kasi if akyatbundok's friend isn't that pihikan about brands, he could have purchased a 5 ch HT system at around that price(9k). And it would still be easier for him to upgrade eventually if he'd get the chance, right? I just wish we gave him the chance to experience HT. But that's just my opinion. Thanks guys.

Sir Arthur,

OT.
Thanks for the concern, I appreciate it very much. It is true that I am very pihikan with brands hence I opted for a 2 channel setup. When akyat started this thread I since then became a lurker at Pinoy DVD, I enjoy reading threads and learned many things from it. The truth is muntik na nga akong mahawa ng SARS, I planned to buy a 5.1 setup last December, but I chose to invest a good digital camera for family use, which I could say I did not regret. I will have my dream HT, but but not this time muna,... mahilig magbenta si Akyat, hintay ko na lang yung Marantz nya ha ha haha! Don't worry,  Akyat's place is the hang-out of the whole barkada if we want to have a good HT experience and he has an enourmous collection of DVD/CD/VCD titles (not to mention his x-tion collections) which we can borrow  indefinitely he he he he ;D ;D ;D. Kaya po marami na yang nawawala na titles. Mind you he is also very hospitable, libre lagi merienda/hapunan namin. I can imagine the listening session you guys have at his place. Once in a while I accompany Akyat  to his many buying/sourcing stints in Pier and just last Saturday we got his dream accuphase.

Keep on postings mga Sirs...CHEERS!!!!

Sir Philander,

Actually isa yan sa una namin nabiling surplus, yan yung naka post sa page 1 ata ng thread na to. Gusto nya sanang i-despose yan kasi kulang ata sa brightness, kaso nagmatch yung bagong luma nya na toy na technics phono sa phono stage ng ES .

Yan talaga ang balak nya magbawas ng amp kung makuha nya yung accuphase. Sabi ko I doubt it, itong hobby mo kako e endless pursuit yan. Kita mo na yung binilihan mo na tao, 50+ yrs na sa hobby wala pa atang nakitang amp na nandun na lahat yung hinahanap nya kaya ang dami din collection.

ganun din napansin ko sa mga idol na oldtimers, yung guru na binilihan namin ng accuphase, bro hanep sa custom rack halos abot sa ceiling... marami siyang amps pero wala kang itatapon ni isa... favorites ko yung vintage marantz receiver niya at pioneer integrated amp both from the 70's... paglaki ko gagayahin ko yun hehe.

yun ang problema, all along akala ko rolled off or "dull" yung sony 333ES... pero nung dinala ni Hans & France yung surplus denon CD player niya, nabuhay ang tunog, ang galing ng match... ganun din sa technics turntable, mas mataba pa ang 333ES kaysa alpha707 pag phono ang inputs, pero sa pioneer dvd ko mas maganda ang 707... ba't kaya ganun?

Post by: akyatbundok on Feb 17, 2004 at 08:03 PM
(...con't)

uh oh.. there seems to be a problem with the preamp section of the accuphase, an occasional static sound that suggests a dirty or rusty contact point... but using it purely as a power amp paired with my tono preamp -- yeeessss, that's more like it.

the accuphase e-305 competes directly with the sansui au-alpha707 (same specs but accuphase is pricier)... doing a side by side comparison, the accuphase beats the sansui with better clarity in the mids and treble... but only by a small margin, because the way sansui rounds off the treble also has its advantages making it sound smooth yet detailed.

Typically, speaker switches are relay-activated, especially in large, powerful and expensive amps.  Contact cleaners will do fine with ordinary switches.  Am just not so sure about relay contacts which are sealed.  Hope your speaker swithces are not relay activated, Akyat.

Sir Av_phile,

Yun nga ang tanong nya sa kin kanina umaga. If this is the case how can we repair it? Can we open the relay or do we have to replace it? If it needs to be replaced, is it ok to look for a replacement or do we need to look for the exact value?

Any suggestion on where can akyat source the component is very much appreciated, since Monday pa nag-iisip si akyat kung pano maaayos yun static... he he he he.
Title: Re:Surplus amps & speakers
Post by: akyatbundok on Feb 18, 2004 at 05:06 PM
its a wierd thing so i'm not yet too ecstatic about the unit... on one hand, its a real "upper mid-end" amp that i got for a bargain, on the other hand there's a catch.

like this morning i played it as soon as i got up, and it played flawlessly that i left home kinda late at 10:30am already, it was that hard to leave... but just last night a couple of friends were asking to hear it, and... ayun sinumpong, like the talking donkey in shrek.
Title: Re:Surplus amps & speakers
Post by: av_phile1 on Feb 18, 2004 at 05:59 PM
Based on experience, some relays are vacuum sealed to prevent oxidation of contacts.  But they are used in expensive equipment like in commerical aircraft where I used to work.  They can't be opened and must be replaced if inoperable.

The relay switches used on home audio circuits are also sealed but am not sure if evacuated.  Many are the clear see-thru types and can be opened.  You will have to buff the copper contact plates which are very sensitive and delicate with a high risk of ruining them.   I suggest you visit Deeco or some beter electronic shops in Raon and ask for speaker relay switch or microswitch.  These relays are either voltage or current activated so you will need to know what the ratings are in the relay switch you will replace.   Better still, dislodge the offending relay and bring it with you when canvassing for a new one in Raon.  

You could ofcourse bridge or short the contacts, thus bypassing the amplifer protection circuit.  I am just not so sure how complicated the circuitry is in the Accuphase amp to safely do this.

Are you absolutely certain it's the speaker relay switches that are at fault?  Why don't you have a good technician look at it first.  You may have some loose grounding somewhere.  Speaker relay switches are often very well built and robust especially in hi end gears.  how old na ba are the amps?  Is it the same for both channels?  For both speakers A and B?

hmmm depends on what you already have... if you have a generic DVD player and you're not satisfied with the audio outs, you may want the Denon for its built-in audio DACS... otherwise it all boils down to which sound you prefer... if it were me i'll get the denon coz i already have the higher model sansui, but if i didn't have a sansui yet, i might get the sansui coz i've already had a denon before... its quite dependent on what you already had.

do consider also arthurallanj's suggestion for sakura amps in another thread... they're cheaper and newer with warranty pa.

it is during these times that i notice how good it sounds.. some complex tracks which sound "confused" and bright on other amps sound natural on this amp.

last night i played it for 4 hours continuously with no problems.. then i went out for a while, and when i came back, i turned on the amp, played a CD, and there it was again, that annoying static sound.. in the morning it was gone.

the previous owner said he hasn't experienced this static sound.. so i'm wondering if it's eating up so much current (power consumption: 830W) that i really need to put it in a separate outlet?  its kinda sharing the same outlet as my 32" TV, DVD player and others.. but i thought it doesn't consume very much when i'm not playing loud.

Is this amp pure class A?  If not, i would be so brash to suggest you leave it on always once you get the occasion to hear it's ok.  Power consumption won't be that much when idle if not class A.  Just to let you know, many audiophiles never turn off their gears unlesss they go on extended vacation.  

Title: Re:Surplus amps & speakers
Post by: akyatbundok on Feb 20, 2004 at 02:18 PM
hmmm this got me thinking again mga brods... the specs say the amp consumes 60W when idle, but maximum consumption is 830W... now when listening at low volume the VU meters say power output is between 1W-30W per channel... so how much electricity is it consuming?  can i assume a little above 60W only?

i'm confused coz i haven't had static for 2 days now, at any volume level.. the only change i made was prior to that i moved the speaker wires to speaker B upon the suggestion of homer.. but strangely, immediately after i did that, there was static, but it was gone after a few minutes.. been in heaven since then.  :)
Title: Re:Surplus amps & speakers

Yup, you can assume it eats around 100 to 150 watts at low volumes, except durig peak musical transients when the consumption can be instantaneously higher, even double. Is your VU meter average or peak indicating?  

It's obviously not class A.  I would say 60 watts power conumsption when idle is OK  So you can leave it ON all the time unless you're out for long periods.

thanks bro av_phile1, i'll do that whenever practical.

naku mr. "golden-ears" nels76, gud luck sa ES amp mo, mukhang pang "rugged use" yan binabalak mo ha, sensya na ang tagal kita binitin... sana hindi ka nagka slipped disk sa pagbuhat nyan hehehe.  ;D ;D

First Impression sa Sony ES Amp.

IMHO, i found this amp neutral sounding connected to my MS 902 and having a VCD/CD Player as the source.

Haven't connected though to my MS 912.

And also this AMP does not get hot easily compared to my Kenwood Receiver on stereo use.

Better dynamics or should I say full-bodied ang sound compared to the 9060D on stereo.

I thought the clipping would be solved when I change AMP. Hindi pala. Still I am not comfortable to listen to high volume. Anyway, this SONY ES - MS 902 is set up in my room (3m x 3m). I hope harshness will be gone when I move the set up to the Sala next month.

Update:

SONY ES AMP vs. 9060D

SONY: Yup. akyat is right. mas mataba tumunog, but bass is stiff and ear piercing (mid and high) at high volume. Malakas and has lots of power reserve.

9060D: Bass is refined, lower, softer. Much more forgiving to the ears at high volume. Much comfortable to listen to.

cheers.

Hi, sir akyat, may question lang ako, ilang watts na transformer ba ang kailangan para sa mga surplus amps, para safe ang operation niya. Minimum?  ???

 Thanks !!

has to be more than the power consumption printed at the back of the amp (with some allowance)... i use a 1000w transformer coz i also connect my surplus TV to it... but i think 500w would suffice if the amp consumes only 200w - 300w.

when using a transformer, i prefer to use 100V rather than 110V... you'll never know how high a voltage spike could go... better if you use an AVR.
Title: Re:Surplus amps & speakers
Post by: akyatbundok on Feb 23, 2004 at 12:29 PM
pareng nels76, mukhang matinding stress test yan ha... the 333ES is rated 105w/ch at 8ohms and 140w/ch at 4ohms... i can only imagine the stress that your mighty ms-912's are undergoing at the point of clipping.

with a VU meter in the amp, i can see that 95% of the time the power output is only between 0.3W to 10W, spending most of the time at less than 2W when playing vocals... but during dynamic peaks, and especially when using the #6 drum track, i can easily reach 130w/ch and above.

You preferred correctly,  jap appliances are rated at 100VAC not 110.  The latter would overdrive them.

onkyo integra A-701D - asking P5,500 (built-in DAC, coaxial/optical inputs)

yeah those "D" models are just accumulating, not very good according to some sansui fan sites... those are the models that gave sansui a bad rep, they tried to redeem themselves thru the "alpha" models but the damage has been done.

Hi , i just bought my first surplus amp, i got the
Denon PMA-780D, meron bang iba pang nakabili nito ? any feedback? for me the denon sounds way better on audio than my yamaha rxv-630. mas buo ang tunog and the highs are very clear,i'm using Wharfs 8.3. medyo mahal lang bili ko, 5.2k. sa cubao ko nabili, meron pa dun isa onkyo integra A-701d, asking is 6k. kunin ko sana yun kya lang when we tried it sa optical wala labas na sound, so i settled for the denon, no regrets naman.  ;D

James lend me his Denon DCD 800 last night.

Now I have the pleasure of connecting it to Roger's Sony ES and my MS 912 for evaluation.

This morning I was already impressed with the sound improvement of this DENON when connected to my Kenwood 9060D and 902.

Will post my review soon on:

DENON - SONY - MS Combo.

Denon and Sony are both surplus equipment.

Problem witht he DENON though is that it does not have a good "grip" on the CD while being played.

hi, just went to the pier today, Latest Sighting : Alpine/Luxman LV-105 hybid amplifier yung may 2 tube sa front. 5.5 k asking. almost bought the luxman dahil sa reviews ni Sir Akyat, but i saw another amp, a Harman Kardon HK 6100 any feedback on this amp it's quite small compared to the other amps but when we tested the sound was quite amazing to my ears. the store wanted 5.5 k for the HK6100 mura ba to or mahal. ? Sir Akyat any views on this amp ? Baka gusto niyo pa kunin yung luxman.  nahawa na yata ako.  ;DThanks !! ;D :-\

nakupo, labanan mo ang sakit na yan hehehe  ;D ;)

thanks for the tip bro, baka bukas wala na pareho yan hehehe joke joke, after the accuphase i swore that it will be the last solid state amp i will buy in the next 12 months, tube naman this time.

dalawang luxman na nasira ko, papaayos ko yung isa with original parts, tapos yung isa gagawin kong frankenstein amp, either gainclone or super leach circuit sa power section while retaining the tube in the preamp section... yung luxman hindi kasing taba ang bass compared sa denon mo, pero gusto ko yun dahil medyo overpowering ang bass ng speaker ko minsan kaya sa luxman mas tight & tuneful ang bass... weakness nga lang niya is medyo bright & confused pag malakas na volume.

(http://img123.ac.yahoo.co.jp/users/9/8/9/1/lapaz4000-img600x450-1066384016hk-6800.1.jpg)

HK6800... i suppose it may be close relative.

120W/ch (4/8ohms 20-20,000Hz)
15.5kg

power output ratings by HK are usually underspecified so expect better performance than similar spec amps from other jap brands.

Title: Re:Surplus amps & speakers
Post by: qguy on Mar 15, 2004 at 01:24 PM
power consumption ...

"guestimate" is divided by 3.5 to get RMS per channel

so if the spec at the back says 180 watts more or less its 60 W/ch...then again...this is guestimate ...

I've recently learned that your amps should have 20% more power than the rated RMS of your speakers. Yung wattage at the back of the amps are usually the power consumption. USUALLY ha? not always. Yung rating kasi at the back of the amps are usually impedance lang. TC. :)

I'm not saying you're wrong bro, ha? Kasi I had a technician friend that even said you just divide the power consumption by 2 and that's it. But amplifiers have efficiency ratings din e, so amps that have higher efficiency ratings convert the power consumption to actual amplification power more efficiently and therefore have higher power to drive speakers. Mahirap kasi malaman ang power output ng amp pag walang manual e. And manufacturers will never give out efficiency ratings ng amps nila. So pag surplus, all you can do is audition.

arthur..

no problem....

like i said its ....guestimate....and was never meant to be accurate...but I use 3 to 3.5 more or less to give me an idea...when there is no other information  to go on....

but it would be best to search the net ...most oldish pioneers/sansui/marantz  would be listed on the net somewhere with the  WATTS / Channel informations

LOD/TRIO-Kenwood /Hitachi brands may be harder to find...

Title: Re:Surplus amps & speakers
Post by: akyatbundok on Mar 28, 2004 at 04:27 PM
yup, i agree with tryaudio, got the same LV105... twas fixed by joan2 just a couple days ago, according to him it really does have a unique circuit, its not your usual tube preamp + ss power amp, it actually uses all ss in the preamp section and hybrid tube+ss in the power amp.

the LV117 is 110w + 110w all solid-state, but i think i saw a webpage describing it has built-in DACs... original price of 135,000yen was a little higher than the LV105 so it might indicate a fairly mid-to-high range model... 7.5k may be a bit pricey for a surplus amp, the yahoo auctions history indicates pricing between 7000 - 12000yen so it should be around between 4k - 6k only.

Post by: audiobyte on Mar 29, 2004 at 08:20 AM
 ;D I also have a Yamaha AX-1200 integrated amp but it's not a surplus. I bought it 8 months ago from a Filipina balikbayan from Japan whose married to a Japanese. This particular model is of limited production and made of only high grade audiophile components. It was exclusively sold in the Japanese market for JPY 128,000.

The sound is generally smooth, clear and clean with very good extension at both frequency extremes. It has a very deep and wide soundstage with captivating midrange (no euphonic coloration as with bottle-shaped amplifying devices! ;D) and of course very powerful. It's conservatively rated @ 185wpc at 6 ohms - remote-controlled volume, source selector, etc. IMHO it blasts away many European and American amps in its price category in both sound and features.

To unlock the muting feature, almost any Yamaha RC for receiver or amp may be used or a universl RC.  :)

i took home the Luxman LV-105u last night after joan2 moved a pair of working mosfets from my other luxman amp... this was the amp i shorted with the speaker wire... he also showed me some tweaks he made, bypassing some electrolytic caps with polypropylene... the whole job cost me P500... funny it only took a few days to fix, i shoulda brought it in months ago silly me... libre pa pukpok sa casing to flatten the slightly deformed cover... firing it up in my bedroom audio setup, wooohooo! its back in business, i hear the same old treble detail and slim but fast bass that i liked... was planning to dispose of it coz i needed the dough but i think maybe not anymore... must be the novelty factor, but i still find it slightly better sounding than my already great sounding marantz sr7300... wooooooo lagot my sansui & accuphase amps are starting to break a sweat.

pre i was lucky coz i saw that both the LV103 and LV105 uses the exact same mosfets... since both amps had one channel gone kaput, we were able to revive one amp at the expense of the other... now the tricky part is that the remaining amp has no more working mosfets (we need 2 each of P's and N's)... but tony is still trying to revive it -- he already identified an alternative mosfet, but unfortunately i was able to find only the P's and not the N's... would have been cheap fix at P70 only... another alternative is to modify the power output section from mosfet to bipolar... seems tricky & dangerous but i told him i'm game for anything since i already have one working... balitaan kita if he's able to fix the LV103.

inexpensive tweak:
- bypass power supply electrolytic caps for better transient response in the high frequencies.

LV103 unmodified

Post by: akyatbundok on Mar 30, 2004 at 04:15 PM
bro, it sounds as good as i can remember it... i couldn't really tell if the tweaks had any improvement or any change at all, since i haven't used it for at least 4 months, but i do remember how it sounds in general... extended highs, not very weighty but fast & tuneful bass, etc... tony said replacing old electrolytic caps is a standard tweak since such parts dry up and degrade over time.

not yet, but they say its a clean sounding amp, i'm lookin for an ss counterpart to my tube monoblocks which are clean sounding as well (btw they cost almost the same as ure mx-1). best of both worlds i guess since the mx-d1 (mx-1s successor) is very expensive :-\
plus the form factor is attractive since its not as bulky as other amps.

BGA VI,

The mute and other functions of your RXV-630 RC may work with AX-1200. Manufacturers usually use the same code numbers for their amps/receivers. What I'm worried about is whether the amp is still available. Good luck!

P.S. If u got the AX-1200 and ur RC didn't work with it, just send me PM.

45mm, these are the onkyo & yamaha models i would be interested in:

Onkyo Integra A-817XX, A-819RS, A-820GT
Most integras at the pier are in this category.  They basically have the same 205W - 210W power consumption so their output power is probably 100wpc and above.  The 820GT is rated 110W/ch.  Model numbers that i've seen are 817 and 819.  The last 2 letters indicate the year of manufacture, where "XX" are the latest models (1987). . . .

Because of this thread, I know the history of my amp now Ü Its an Integra 817XX which i did not know anything about, except its visible functions, much less what the "XX" extension meant. It was brought from Japan.

Would you know anything about the Marantz PM 54DS? I was told that the PM stands for Philips when it bought out Marantz?  What about the DS extension? This, too, is from Japan. I was told that it was a showroom unit.

:) Thank you!
Title: Re:Surplus amps & speakers
Post by: akyatbundok on Apr 05, 2004 at 12:43 PM
kaffee1, i think marantz pm-54ds is an entry level integrated amp late 80's model... there are higher models 64, 74, 84 up to 94... the "PM" prefix is still being used by marantz in new models... it probably stands for "Pre-Main amp" coz that's what the japs call an integrated amp... the "DS" i'm not sure, but i did see the sequence of models being mentioned... PM-54 --> PM-54D --> PM-54DS... so that probably means the DS is newer than either a D or none... not sure just guessing.

Title: Re:Surplus amps & speakers
Post by: av_phile1 on Apr 05, 2004 at 02:32 PM
To my knowledge, an Onkyo affixed with the Integra name is not entry level.

To my knowledge, an Onkyo affixed with the Integra name is not entry level.  

Hmmm. interesting thought there. Yes, it does sound good. Was wondering about its Contrabass feature initially, till I discovered that it mimics a sub even if it is hooked up to a pair of 3-ways only. Btw, it also has dials for the VCR, so I suppose it was one of those models which already had the video sound output in place?

Thank you!

The place can really be overwhelming of choices.  Good thing for me they don't accept credit cards ;D

My last visit there was in Feb. So far, mababait naman sila.  As you walk through the stalls, there'll be many who will offer their wares, short of begging.  Just tell them you're just canvassing and not yet buying.  The salesguy in one stall with an enormous inventory of amps and receivers seemed accomodating enough.  They're ready to have your choice tested without a promise to buy right away.   But if you see and test a really good unit, haggle for and get it right away.  Chances are you won't see it again when you return to buy.    ;D

Title: Re: Surplus amps & speakers
Post by: audiobyte on Apr 14, 2004 at 11:27 PM
BGA VI,

Good! It's really a best buy and a rare find! It uses the same technology as the present high-end Yamaha audio and HT amps now sold outside Japan including the MX-1. I'm using mine to drive my reference pair of Fostex single driver (full range) backloaded horn speakers. But beware! This AX-1200 frequently prevents me from listening back to tubes as they seem to slow down the music compared to this Yamaha.

Enjoy the music then!  ;D

sir akyat, thanks . ok naman yung amp aside from some scratches sa top grill, and may crack sa wood panelling, i plan to replace the wood panelling with real wood kasi laminate lang naman yung original. sound is very good, especially with the surplus onkyo speakers.

baka ibenta ko na yung Denon PMA-780D, baka gusto mo ? Thanks !!! :D
Title: Re: Surplus amps & speakers
Post by: sandawa on Apr 17, 2004 at 09:49 AM
just to provide some info. if you can't get specs of your used gears, click this site: http://www.selworld.com/audio_video/data/index5.html. find the model number of your unit (brands are not shown on the index page), then auction prices would appear. at least you'll have an idea how much they're sold in Japan and could be used as reference in haggling with the merchants.

btw, yamaha of japan is quite helpful with regards to inquiries. i had an ax-1 (100wpc), which looks very similar to ax-1200, bought here in davao for P5T three years ago and yamaha japan gave me all specs when i inquired thru email, including the retail price of my unit when it was sold brand new. i eventually swapped it with a sansui alpha 907 last year.

maraming naliligaw niyan dito sa davao. i saw one last december, alpha 907i mos but it was selling at P12T. maganda talaga ang alpha 907 sir, malinis at mataba ang tunog. it has the sonic character of the british amps but with the heft of american brands. toroidal transformer is about 30 kilos. BTW this one puts up 160 wpc RMS and sounded a lot better than my Musical Fidelity A-120, Accuphase E-302, and my old 907F.
Title: Re: Surplus amps & speakers
Post by: av_phile1 on Apr 20, 2004 at 06:11 PM
The Sansui Alpha series was probably the last great amps from the brand.  With its X-balanced config and toroidal transformers, I wanted to get one during the late 80s, but settled  for an Onkyo Integra separates to replace my aging Sansui AUD11. (Obviously I was a Sansui fan.)

Then I became an Onkyo fan.  ;D  If you can also find old Onkyo Integra P301 and M301 or any of their P and M models (for preamp and power amp, respectively) get them too.

mga sir, mahirap maghanap kahit dito sa davao niyan. 'yung 907 maraming naliligaw dito. about 5 years ago, i got a 907F at P3.5T. at that time i also saw 907F-Extra and 907Decade which were being sold at P5T each, i think. two years ago, i swapped my yamaha AX-1 plus P2T cash with an alpha 907. last december, i saw an alpha 907 i-mos but someone bought it at P12T after i haggled and offered P10T.

BTW, i just saw here a Yamaha B-70 which is rated 200wpc (on niji's best Japanese audio list) being sold at P6,000. i have checked this unit at Selworld (Japan's Yahoo auctions) and it's still qouted betwen 20,000 and 40,000 yen. i remember seeing an Onkyo P-1 but lost interest in it when i saw its Selword quote which was really low.

i have a copy of Hi Fi Choice early 1990s and Sansui Alpha 907, similar to what i got, was selling at 1,800 pounds, much more expensive than some high-end british amps. i also have a Musical Fidelity A-120 bought in Pacific Place/HK for HK$5,000 (about US$700) back in July 1999 pero ang layo ng tunog sir. the MF sounded so inferior (siguro kasi 40-watter Class A lang) using my old reliable Epos ES14 (Robin Marshal-made, not Michael Creek.)

BTW, i maybe wrong, but my sources here said these surplus electronics arrive here in Davao thru the banana boats from Japan. since the boats' mission is to pick up bananas and thus arrive with almost nothing, one or two containers filled with junk items are unloaded almost free from freight charges, and released, konting ayos lang sa customs. most of these surplus electronics go to Manila's pier dahil nandyan ang market but some of the upscale models remained here.

Seems googling the model just returns two jap sites.  Try the Toshiba website and check the various regions if they have AVRs.  Then see if they have product archives for old models.

Post by: wanderlust on May 07, 2004 at 10:02 AM
i went to cubao last tuesday, to just simple kill time around a/v surplus shops in the isetan area and i went home with a LUXMAN L-430.

roaming around the a/v surplus shops of pier and cubao have become a new found hobby ever since i started reading this topic, and i even got a list of the most sought afters (hehehe, bagong competition ako sir akyat ang all others).

i bought the L430 primarily on account of sir akyats recommendation,"u cant go wrong with a luxman", and on the fact that on its back an indication is made that it can handle 4 ohms to 8 ohms, on speaker A or B and 4 to 18 ohms for both speaker A and B.

initial impression (after 3days or 9 hours of listening time) of the amp: improve bass, better seperations of instruments, and a WOW! for voice, it is as if the singer is with me, live!

it is driving a pair of hard to drive celestion 3000 speakers, with a 100 watts @ 4ohms power requirement. previous to this, i drive them speakers with a yamaha avr, and the sonic difference is very much obvious, specially on the instrumentations. laki ng ginanda ng goya ko from a very untamed acoustic guitar leads to a tamed yet realistic sounding performance.

what can my fellow surplus fanaticas comment on this amp? O0 O0

thanx in advance.

thank you sir akyat, i was hoping for your reply.

will post the actual pic of the unit soon, medyo not in a very apprecaible condition na yong outside but malinis naman inside. and only 1 of the selector lights is functioning. the wood design located at each of the front edges of the amp is missing.
does your lux sir akyat have this little red lights inside? mine has i think 8 pairs and in one of the pairs there is one light that no longer is lit.

you really cant have your cake and eat it too.

also, and my apologies for being quite naive, i have been wondering eversince i got this amp, what is the function of this and its obviuos effect:

  - Filters:
---Subsonic 30Hz -6db/oct
---Hight-cut 7kHz -6db/oct

and why is it that only the phono input is made of gold in this amp............  :'( :'(waahhh, unfair, im no phono fan as yet.  ;D

thank you.

i went to cubao last tuesday, to just simple kill time around a/v surplus shops in the isetan area and i went home with a LUXMAN L-430.

roaming around the a/v surplus shops of pier and cubao have become a new found hobby ever since i started reading this topic, and i even got a list of the most sought afters (hehehe, bagong competition ako sir akyat ang all others).

i bought the L430 primarily on account of sir akyats recommendation,"u cant go wrong with a luxman", and on the fact that on its back an indication is made that it can handle 4 ohms to 8 ohms, on speaker A or B and 4 to 18 ohms for both speaker A and B.

initial impression (after 3days or 9 hours of listening time) of the amp: improve bass, better seperations of instruments, and a WOW! for voice, it is as if the singer is with me, live!

it is driving a pair of hard to drive celestion 3000 speakers, with a 100 watts @ 4ohms power requirement. previous to this, i drive them speakers with a yamaha avr, and the sonic difference is very much obvious, specially on the instrumentations. laki ng ginanda ng goya ko from a very untamed acoustic guitar leads to a tamed yet realistic sounding performance.

what can my fellow surplus fanaticas comment on this amp? O0 O0

thanx in advance.
Rather unfair to compare your luxman to a yamaha.  Like comparing heaven and hell.  ;D No offense meant to yamaha users. 

The luxman is a respeted US brand that has been in the mainstream of hi-fi audiophilia ever since.  I fellow audiophile once said, just touching the front fascia is enough  to bring him to fits of ecstacy.  ;D  I was drooling at these brutes at the Audiophile shop in Goldcrest before. Even their casette tape decks had a built and look that was difficult to dismiss, apart from the nakamichi. 

Congrats with your purchase.  How I wish those surplus shops were nearer to my place.  sighhhhh

 condition of the amp is actually very good externally, na test  na namin kaya lang pag turn mo nung knobs sa middle very scratchy yung sound, sabi ng store owner capacitor daw, pero tingin ko contact cleaner lang.  ;D

This M506 was the flagship onkyo separates that carried the INTEGRA name.  Competes with the likes of Pioneer ELITE and Sony ES lines.  There really should be solid wooden panels at the sides.  I think the later model is the M508 or M588, if not mistaken.
Title: Re: Surplus amps
Post by: Narayan on May 12, 2004 at 10:10 PM
as per my copy of onkyo's 2000 audio-video catalog, the top model is the M-588 which has wooden side panels like the M504. am not sure whether M506 also has these side panels as the model is not in the catalog.

these are very good units such that for the P304/M504 combo for example, these were in production for 12 years :o

Post by: Yahoo! on May 15, 2004 at 03:50 PM
I visited pier this morning, while looking around for an amp and cd player, I came across a similar ONKYO amp posted by sir BGI_VI. Kaya lang the label shows 100W below the analog meters and no model number indicated in front.  Sighted new items were Victor AX-Z911 going for 4K, Sansui AU-D907X, Sony 333ES's different extension from what I got, NEC A-10 Type III, Onkyo 54s, Kenwood Trio 7300, 8700, etc., Sony/Pioneer amps wtih ProLogic and an Alpine/Luxman LV-103. 

Anyway, I came home with a SONY 333ESXII amp (previously reserved) and an Onkyo C-200 cd player. My problem now are the speakers. I already have a Sansui AU-D607 and a SONY CD player, also from pier.  Reading from other posts, they said that it is better to overpower your speakers than underpower them.  Tendency of damage to speakers if underpowered is higher than the amp.  I'm thinking Diamond 8.4 or from the Buy & Sell section an AE 109 selling 10K.  Somebody from another thread said that the power rating for the Sansui I have is 85wpc.  What would happen if I connect a pair of 50W old speaker from an old stereo component? How about for Sony 333ESXII, would somebody know the power rating for this one?  At the back panel of the Sony, 345W of power consumption is indicated. 

I'm just a newbie in this hobby, I've been reading your posts daily and have been very much influenced, informed and educated.    :)

BTW, I also have a Sakura 387 amplifier for my budget HT setup and a Rongxin 89DV 5.1 speaker set.  I would like to upgrade this to Diamond wharfs that's why I'm considering  the 8.4 for my stereo setup.

Any suggestion is highly appreciated.

Thanks

Thanks to your post seacrmnd, I bought the Sansui AU-D907X. Testing it now, so far its ok pa naman. Noticed  that its much much powerful than my HK3550, the bass is a lot more heavier, with more impact, but then again, yung highs is parang HK, medyo subdued. Sayang, di sya alpha series, but this series i think is the 3rd generation of the 907. Any ideas if this is correct? If this series brought the downfall of sansui? :P

bro, your amp is 6th generation... 3rd generation is the AU-D907F.

be proud of your amp, it's their flagship integrated amp in 1984... it is included in nishi's list/history of top-rated japanese audio gear.

The downfall of Sansui was more from the labor problem, the appreciation of the yen against the dollar, and the brand's introduction of inferior line for the international market (since it could not sell its high-quality hifi to the world market at realistic prices). I was on a study grant in Japan during the mid-80s and I had the oportunity to interview some audio company executives on the impact of strong yen on their operation for my term paper. Your D907X is an upscale unit comparable with the high-end models of US or British brands. It should do well with mid- to high-priced British speakers. I have four other pairs - Wharf, EV, and two JBLs - but my Alpha 907 sounds best when hooked to Epos 14.

been to pier again this morning, no new items except for the Sansui Au-D607X Decade going for 3.5K and an AU-D907 going for 4.2K.  So off I go to Raon, to buy and audition sana Dai-Ichi subs kaso sarado pala showroom pag Sunday. So I wandered around and there I found an Alpine/Luxman LV-117 going for 5.5K.  I remembered someone in this forum stated that "you can't go wrong with a Luxman".  So I haggled and bought it for 5K.  I still have to test this with my speakers though.   Just sharing and wnat to know If I made a right decision for my acquisition.
Thanks...
Title: Re: Surplus amps
Post by: sandawa on May 23, 2004 at 03:31 PM
I remembered someone in this forum stated that "you can't go wrong with a Luxman". 

That depends. It's likely to apply if you're buying a brand new equipment since Luxman is among the best audio brands in Japan (although its recent Japan auction prices using comparable models put it only at par with old Sansuis - D series - and new Yamahas). LV 117 is a mid- to high model with probably 120wpc. When buying used gears, however, it's better to request the seller that the cover be removed for you to see if the electronics have been tampered with. One that's dirty and evenly dusted likely indicates no replacement of parts was done. Shiny, clean caps and boards could mean the unit was already repaired. Bear in mind that the risk of buying a lemon is always high in the used equipment market. But taking into account the pricing and the available hardware (i.e., upscale models sold at less than a 10th of the original price) it could be worth the trouble as well as the risk.

sir,

i dont want to be the bad egg >:D, but i have heard some personal comments regarding the marantz pm-80. and it isn't inspiring.

actually the pm80 was part of my list, but now it is no more. his impression of it was that it was quite bright to the point that "nakakapagod makinig". i cant go to details here for one reason or another, but at that time, we were listening to another brand of amp (d surplus) and he compared the sound of it, as the sound of his marantz, and if his comparison holds true, i wont left a finger at it. in fact the amp that we were listening to at that time is now and difinitely, history. :'(

patience lang pre, sooner or later may maliligaw din... pag ginamit mo agad yung 4k/5k mo wala ka na pambili kung may lumabas na high-end.

yung onkyo 917 mas bago pero parehas lang sa specs ng mas luma na 817 at 819... kung marantz hintayin mo na lang yung PM-94 iba yata kasi ang design nung lower models eh... narinig ko na rin yung PM-80, parang ok naman hindi lang sya standout, compare namin sa hafler DH-220 mas maganda ang hafler...

I'm not an Onkyo fan, although I have owned some Onkyo amps before - and CD players 901XD and 501XD now - but I believe you. I just checked Audiogon's guiding price for used equipment available in the US and that combo currently sells at an average of $1,000 based on eBay and private hifi auction records. In Japan, that same package, used but in good condition, goes for Y50,000 in an Onkyo auction site. It's a pity, Selworld (Japan used audio price directory) is no longer accessible. It gives a more accurate pricing for surplus audio equipment since its records for each brand model extend to two years of auction deals. It's quite surprising, as per my monitoring since 2002, but our surplus dealers here sell those items at lower than average Japan auction prices.

I don't know about those Japanese auction houses, but my informat tells me that those "surplus" appliances are actually hauled off en masse from junkyards in Tokyo and elsewhere.  The haulers are actaully PAID to take them out.  So the only capital here are the freight charges and maybe some customs duties, if at all.  And luckily for us, those entrepreneurs know very little, if nothing, of the merchanidise they are disposing.  Those that do are the local bidders who make some tidy profits refurshing them and selling them at the Port Area Shopping Mall and elsewhere.

That explains the huge junkyards run by Japanese-Filipino firms here in Davao which are right next to the warehouses where surplus imports are unloaded. Davao, as history books noted, was known as Little Tokyo before the war and until now, we have a fairly big Japanese community here. So, we're being used as dumping ground. But then, how come many of these equipment arrive in good condition?

A-okay TVs, some widescreen, filled the warehouses of Japanese importers here: 28-inch at P2.8K and 32-inch at P6K. Normal screen 25-inch TV is retailed at P2k. A guy I know who owns a shop specializing in surplus items said he'd just deposit money in these warehouses, say P50K, and he'll get a call when a container van comes in. He'd get priority in choosing the best amps he'd see and his gauge is power consumption at the back of the unit. I was told these importers used to quote a maximum of P5 per watt, depending on the amp's external condition, but since they found a big market there in Manila, it has now gone up to P10 per watt.

Okay lang, mura pa rin.
Title: Re: Surplus amps
Post by: av_phile1 on May 24, 2004 at 08:01 PM


But then, how come many of these equipment arrive in good condition?


Two reasons:

(1)  The japs who owned them are affluent enough to dispose of perfectly working units in 3 years time or less to make room for newer models that have more features.  That is actually the norm with very fast technical advancements that japanese electronics undergo.  They're not really "junks"  the way we have come to associate the word.

(2)  My informat tells me that if you see how they are tossed around at the pier, and still work when tested, you'd come to admire these "surplus's" robust qualities.  That's a telling testament to the high quality of these disposed appliances that are rumoured to be far superior to their "for export" counterparts.  Ofcourse, they do get some "retouching" by the sellers.  Cosmetically, mostly.

I guess you're right but I think a big chunk of used audio in Japan is still absorbed by the domestic market. The Selworld register, when it was accessible, showed hundreds of consummated deals in a week's time on just one equipment model. And there are thousands of them. In used Sansui Alpha series, for instance which I monitored closely since I was lucky to own one, I found a hundred deals in one month with quotes hardly going out of a specific price band, ranging from 50% to 80% of the original equipment price.  Yet these equipment were about 10 to 15 years old!

That's not the case for similarly aged equipment from other brands where average auction prices ranged from 5% to 10% of brand new price. My observation was that Japan auctions on British and US equipment had the same price band as Alpha series and Accuphase, as well as esoteric brands, but the others go down really low. I tried cross-checking this out with Audiogon, and partly eBay prices, and except for Alpha series, which is not available in the US, the pricing patterns were somehow similar.

To me, high re-sale value could mean a reflection of quality and personal preferece of Japanese audiophiles. And I respect their taste. That might also explain why those brands/models don't normally get shipped to Piripin/Davao-kou junkyards.

Mga bossing, I am a neophyte when it comes to surplus amps... But I got so interested upon reading all your posts...

Please bear with me with these questions:

1. How does these surplus amps sounds compared with the mini-compo available in the market today, like sony, jvc and phillips?
2. If I will opt to buy one surplus amps can I use the speakers of my components coz I have currenly four of them right now?
3. Speaking of sound quality which is better sounding, the Branded surplus speakers which is more or less using the technology of the 80's or itong mga bagong speakers ngayon na di naman masyadong high-end pero using the latest technology?

Yung lang po at maraming salamat....

list #2 (http://www.niji.or.jp/home/k-nisi/premain2.htm)
list #3 (http://www.niji.or.jp/home/k-nisi/premain3.html)

patience lang pre, sooner or later may maliligaw din... pag ginamit mo agad yung 4k/5k mo wala ka na pambili kung may lumabas na high-end.

yung onkyo 917 mas bago pero parehas lang sa specs ng mas luma na 817 at 819... kung marantz hintayin mo na lang yung PM-94 iba yata kasi ang design nung lower models eh... narinig ko na rin yung PM-80, parang ok naman hindi lang sya standout, compare namin sa hafler DH-220 mas maganda ang hafler...

naka-B4 ka pre bagay dyan sansui alpha907 pero unahan kita hehehe  ;D

pre ok na ba yong   Victor AX-Z911 sa 5K?

Yung lang po at maraming salamat....

(1)  Admittedly those mini-compos you see at Abenson and SM appliance can look and sound impressive at first sight.  But a jap surplus integrated of a known brand that is still is excellent working condition is a steal, to say the least.  I mean between a fresh P45T JVC compo and a P5T Sansui alpha or au series amp that still works, i consider it a no brainer to choose the latter.   Most of the amps, integrateds, receivers and players at the pier WERE mid-to-flagship models of the past and had commanded steep prices for their import versions.  Some were actually my "dream" amps 10 years ago. 

(2)  If the speakers are rated 8 ohms, there shouldn't be a problem using them in the interim.  Knowing most separate Japanese amps are rated from 6-8-16 ohms, you could have some mismatch if the compo speakers are rated 4 ohms which they usually are.

(3) Speaker technology hasn't really been as revolutionary as  those digital processors have been over the last 10 years.  In fact many audiophiles find 30 ++ year old speakers to sound just as excellent if not better than many newer speakers at a fraction of the cost. That is on the assumption those speakers had been well cared for by their owners.  I've seen some Pioneer, Yamaha and Technics speakers at the pier that looked original with well-maintained cabinetry.     In terms of sonic quality, they can be at par with many entry and mid level speakers of today.  Some were flagship models of the past that are a steal today. Just have them tested for buzzes and rattles at high volumes typical of old speakers.

ahhh hehehe.... na-curious din ako sa modelo na 'to kasi nasa website siya kasama ang mga high-end amps.

main selling point is the built-in 16-bit DAC... it shortens the analog signal path to about 0.5m... they also claim to do some high-speed switching at the DAC level to mimic a Class A amp (?) at 120wpc 6ohms.

the higher model AX-Z921 seems to have a better DAC (18-bit).... but i'm most curious about the "K2 Interface" mark at the front panel.... it's the same technology JVC uses to manufacture XRCD's.... i don't know what the K2 interface does, but in the 90's Victor released a CD player/DAC combo that has a K2 interface and it cost 1.4million yen.

To those interested in collecting really vintage amps, just saw a classic, Sansui AU-777D. This is the first ss model sansui released after ending production of their tube amps, read somewhere that this model number's tonal quality was specifically designed to mimic that of tube amps. First quoted price was 4,000. Pwede pang babaan to 3,000 malamang. Parang transistor radio ang dials, merong bias adjustment for treble, mid and bass, 35watts per channel lang. One more thing, ang linis pa ng itsura, nanduon na sya sa dulo, malapit na ng BPI ba yon? lampas pa ng tindahan na merong stacked speakers sa labas.

Wala akong nakita na worthy of a second look... Gas-gas na lahat naka display at parang medyo malayo duon sa mga iponopost niyo dito..

May nakita po ako in one of the pawnshops here na naka-auction na "Luxman Surround  Amplifier for 3.5K di ko pa na audition but just in case is this a good buy?

Title: Re: Surplus amps
Post by: yukon on May 27, 2004 at 03:24 PM
bai jolam, nasa pawnshop?... ibig sabihin hindi yan kasama sa mga surplus goods. hhmmmm,

it's a steal at 3.5k, but then again most surround amps are designed in the concept of recreating a movie theater, not for "pure" audio listening... well, if you want to have both HT and Audio in one box, Luxman should do.

by the way, dolby digital na ba or dolby prologic pa?...

asa man dapit ang palitanan ug surplus diha bai? naa ba sa baslayan area?

Guys, any info on the following surplus amps:

Onkyo integra A815RX II
Sansui AU-9500DSP
Sansui AU-V7000
Victor AX 900
Yamaha AUX 1000 III

I saw these amps in pristine condition, parang bago. These are not part of wholesale surplus but are shipped from Japan by air freight. Prices range from 6-8 k, medyo mahal but makinis naman. I cant decide what to get, pls provide info if available. thanks.

Guys, any info on the following surplus amps:
Onkyo integra A815RX II
Sansui AU-9500DSP
Sansui AU-V7000
Victor AX 900
Yamaha AUX 1000 III

Go surfing and you'll surely find bits of info about these equipment. Onkyo A815 I think is a low-mid model since A817 bids at less than $50 equivalent in Jap auctions. Take note, however, that auction prices quoted are usually 2 to 5 times less than the amount they're actually sold. Only the registers, such as Audiogon in US and Selworld in Japan, provide realistic pricing for these equipment. Pricing generally reflects model quality and condition of the equipment. However such market data are now for sale but indicative pricing as per current auction offers, not starting bids which could go as low as Y1,000 even for high-value equipment, are still available.

The Sansui AU9500 is a classic made in early 70s, so it should be about 30 years old. If that's the case, beware, sooner or later you'll have to change its caps and transistors and unless you're a collector or avid Sansui fan, it could be a major hassle. If what you saw looks new, it could be a re-issue of the old classic 9500 and at prices you quoted, it's a "giveaway." The company started issuing oldies to the domestic market at extremely high prices to compelement its release of Alpha series in late '80s to signify its shift to specialized audio manufacturing (although it maintains commercial-line subsidiaries for low-cost appliances in Japan, China and India.) I'm not familiar with the AUV7000 but it could be part of the brand's audio-video commercial line.

You could check the Victor amp with the JVC catalog since the two brands are the same (like Diatone and Mitsubishi, Lo-d and Hitachi, Optonica and Sharp, etc.) The model number 900 could mean it's up on its scale but then, JVC isn't really that famous for hifi. Check the Yamaha website for the AUX-1000III, especially the download link, I think you could still get a copy of that model's manual. I still have the old Yamaha CA1000III (on my attic) and it's rated 100wpc RMS. If the equipment you saw is not on the Yamaha website, send them an email, you'll be surprised to get a reply in one or two days.

Sandawa,

thanks a lot for the info, very helpful indeed in my decision. I have seen other units in the same shop with some idea of the specs based on this forum. They are :

Victor AX-Z921 and sansui AU-D607F extra and Marantz PM-74 D. What will you choose if you were me  ;) Hope you can give a try. thanks again.

BTW ill be using it to power an audience 42.

Sorry, except for AUD-607F, I'm not familiar with the other two. If it was a Marantz PM 94, I'll say grab it. AUD-607F is a 1980 model with about 80wpc RMS, so, adequate for even low-efficient speakers. Its US-model equivalent is AU-D7 to D9 (AUD907F is AUD11 in US). Considering you have other options, as mentioned in previous post, I'll pass on this three and look further into the first set. Of course, other considerations are external and internal conditions - see if electronics inside are clean or covered evenly by dust. If clean, it's been repaired. Also, you should hear how it pairs with your speaker. What I usually do in buying used equipment is offer the seller a return option within two days. I pay him an extra amount, say P200 to P500, on top of our final price with the option to return within two days if I didn't like it. If I return, I get a refund of the final price but lose the P200 to P500 extra I paid. If I don't return, I lose the extra cash I paid but I'd be perfectly happy I got what I wanted.

Sansui AU-9500DSP

You got me confused with this AU-9500DSP (?). I think what you saw was a metallic-champagne AV-9500DSP. I remember this amp in a small shop in Causeway Bay HK being sold used at more than $1,000 years back. I was told it was Sansui's top of the line HT amp with 6 surround channels and that its original price was over $2,000. This was before the 6.1 surround hype was peddled by HT equipment producers. Thus, if all 6 channels of the amp you saw are working with no audible distortion, it's definitely a "good buy" even at P10K.

I don't know the condition of your Audience 42 but I'm wondering why you'd let a surplus amp (unless upscale model) drive it. I think it's better paired with an expensive Brit or Yankee electronics (or even valve). Or, like the posts of other enthusiasts here, it's probably better to wait for a top-of-the-line Jap surplus to at least harness your speakers' potentials.

Cge dre, balitaan mo ako thru text kung merong mga naliligaw na alpha dyan or mga luxman. :) Yung Sansui ko sabay sinugod sa doctor for general checkups, pero di pa tapos yung akin, kay wndrlust yung inuna. Sana matuloy yung surplus amp shootout natin. Interesting how these oldies compare with the new ones.

hi,

 Oo nga kelan ba yung surplus amp shootout natin ? for sure di na tuloy this week nasa shop  pala yung dalawang amps.   

 Sir akyat, next week kaya ?  ;D

Sir dohbert, wanderlust, may pinalitan na parts ba sa mga amp niyo ?

Baka may makuha ako isa pang amp, nandun rin sa niji list. heavyweight !!!HEHEHE!!! >:D >:D

Alam ko na minamata ni BG_AVI :) Yung akin palit speaker connectors, naging malutong yung plastic, naglaglagan :P tapos linis. One good sign na di nakalikot yung amp is kung pantay yung kapal ng alikabok sa loob :)

sir dohbert,  hindi naman.  :)

gusto ko lang malaman kung meron ding mapapalitan sa amp ko para maging mas ok, ;D

Yung denon ko kasi parang ang sakit sa tenga ngayon ,yung highs sobra, or maybe yun talaga characteristic ng amp na yun or sa tenga ko lang yun. baka malagay na sa assorted buy and sell . pambili ng bago, ;D ;D

i think somebody here should start a thread on easy amp tweaks/modifications like this. even fixed equipment power cords could be safely replaced. shifting into high-quality power caps, for instance, could make significant sonic difference i was told.

BG_AVI, yep, generally Denons and Onkyos are mas makalansing than HKs or even sansuis, na try mo na i-match yon sa Denon na cd player? warm sounding yung player baka makapag compensate.

yes there are, try going around nalang sa pier, i think lower wattage amps are equally abundant as with high wattages ones.

as to the price i am not quite sure, but the rule of the thumb there sa pier is that the higher the watts the higher is the price, so it goes without saying that a 50 below would be priced quite lower than a 22o wat amp. my guess, it will be priced around 2k to 3k, or even lower. btw, the wats is not computed per chanel, so if yopu happen to see an amp with a sticker up front with a 100w it is safe to conclude that it is rated at 50w per channel.

i am a proud owner of a surplus luxman as well. i love it so much that after  a week of use (d pa sawa!) i sent it to an amp doctor! this to ensure a longer if not lifelong companionship with my luxman. and mind you, the hard part is that i havent had fully enjoyed it when i sent it away, now, i miss it so...

i think the AU-D907X is worth a second look/audition even at P7.5K. it was supposed to be the best amp (AU-D907X-Decade) in the D-line immediately before the Alpha- series was introduced. rated at 160wpc RMS @ 8 ohms (250wpc @ 4 ohms), the only difference is that the first Alpha 907 used toroidal transformer and had XLR balanced power amp jacks for optional professional use. if you're a rocker who wants to match your neighbor's Krell decibel-for-decibel, this could be an inexpensive option for a face-off with Dan D'Agostino's toys. BTW, with a maximum power consumption of just over 400 watts, the retailer got that at less than P5K, so he'll likely sell it at P6K.

sir, try to walk the walk and youll see more.

sir, if you walk a little farther, like going towards the docks yopull see a BPI bank, in the area youll see some small stores that sell mostly amps and cdps. as the place isnt well kept, cost of maintenance wont be added to the prices of their wares, but they do know what they are selling now so expect to haggle for a better bargain.

Also saw there was Kenwood L-03A also at 370W power.  I think this is a lower model since wala pa CD dun sa input selector nya so I opted for the KA-1100SD, instead D.A.D/Aux yung label.   Also there were Sansui AU-D707X rated at 320W, Sony 333ESat 270W and Sony 555ES. 

OT, are the Sansui CD players OK?  Saw model alpha317R with MASH kaya lang parang sobrang sensitive yung lens, konting galaw lang sa case  nag-skip kaagad.

congratulations. what's nice with getting high-power amps, especially if they sound good, is probably you won't be spending anymore on low-power gears, except for valve amps. also, high power amps have high marketability, thus resale value could even exceed your acquisition cost. i'm not sure about this but the Kenwood L03a was a limited edition power amp while the unit you chose, KA-1100SD was newer but didn't rate well in the reviews. i could be wrong though. the bottom line - hindi ka lugi.

Since we're on the lookout for excellent values on surplus amps, any remembrances of the best buys from japanese brands between 1975 to 1990 which I believe is the vintage of most surplus amps out there? 

I would think the Onkyo Integra models, whatever series, would be among these.  Same with most Sansui AU models. 
Title: Re: Surplus amps
Post by: number1 on Jun 15, 2004 at 03:25 PM
i found this passage quite interesting and I'm merely quoting this.

"Most of the Japanese made integrated amplifiers offer little or no sonic advantage over a receiver. There are companies such as Krell, Plinius and Arcam that manufacture integrated amplifiers that offer a very high level of performance--if not the ultimate. It is possible to get very high quality sound from some integrated amplifiers."

source: http://www.norh.com/docs/amps/

what do you think?
Title: Re: Surplus amps
Post by: akyatbundok on Jun 15, 2004 at 04:38 PM
its a sweeping statement but understandable.... there's actually a very good explanation for this.

people outside of japan have this impression of mass-market quality, well because they are mass-produced.... the japanese keep the best for themselves while we get their low-quality stuff.... you can't really blame them, it's the currency exchange..... in the 80's the japanese yen was so high that an imported japanese amp would be much more expensive than it should be..... the only way to bring down the cost and compete with other brands was to mass produce.... so that's what we get, mass-produced products..... there won't be much of a market here for premium amps costing 100,000-250,000 pesos.

so the best japanese amps are sold only in japan.... ironically, we can get them as junk.

anyway.... 47 labs, accuphase, esoteric and audio note (japan) can compete in a very big way against krell, plinius and arcam.

I just came from the pier. I saw a sony 333es. Originally was planning to get the 260w Sansui A-d907 limited, but I changed my mind when I saw a Sony 555 EsxII. I wonder if i made a mistake?  ???

Btw, the sony has gold connection for the cd and it was so so so so so heavy.  :P

I also saw a couple of onkyo a-817's....Lots of lower-end Sansui like 607, 707, 307,....

What do you think sir akyat? 
Title: Re: Surplus amps
Post by: akyatbundok on Jun 15, 2004 at 06:30 PM
yeah its really heavy... yours is a higher and newer model than the 333esx i once had... it should match well with the sony 555esd CD player... i tried to match my 333esx amp to a 333esd CD player but unfortunately the CDP i got was busted.... it did match very well to a denon CDP, and the new owner is now enjoying this matchup, although due to the success of the sony 337esd in the last CDP shootout, i think he's now hunting for a sony CDP to match it with the amp.... btw, i thought it didn't match very well with pioneer DVD players.
Title: Re: Surplus amps

Title: Re: Surplus amps
Post by: D0Hbert on Jun 15, 2004 at 07:10 PM
Saw that same sony amp mga 2 weeks ago, was about to get it when I noticed that some parts were already repaired. I had the unit opened, it has 2 transformers kaya ang bigat, pero sa gilid may sticker ng repairman, dated 6-1-04. Sabi ng tindero all orig, eh nakita ko yung sticker, sabi ko akala ko ba all orig eh nanduon yung sticker ng repairman, so kinausap ko yung nag repair, sabi pinalitan lang yung resistors. :I
Title: Re: Surplus amps
Post by: akyatbundok on Jun 15, 2004 at 07:21 PM
i prefered the alpha707 matched with my current gear but it wasn't really a fair comparison because they were positioned differently in the market.... the equivalent amp models of sony and sansui are better matched this way:

333 = 607
555 = 707
777 = 907

so i think your 555es would be a better match to my alpha707 in terms of parts & specs.... there wasn't a very big difference in sound between the 333es and alpha707, its just that the highs of the 333es seemed a tad softer.... the 333es CDP that i briefly tested had a well-extended treble so i think that would have been a great match -- the amp taming the highs of the CDP and the CDP adding life to the highs of the amp.... unfortunately the CDP played only one song then went kaput.... they forgot to lock the CDP so the mechanism must have disaligned (some old CDP's have a lock to hold the mechanism together while being transported).

Post by: D0Hbert on Jun 15, 2004 at 11:29 PM
I think its still a better buy than the 907 limited, the sansui is a pretty old model, no cd inputs yet, the sony is the better choice, but i didn't get the chance to test the unit myself. When I opened the unit, everything is squeeky clean, which means na may na repair na dyan, that's why i got curious and looked more closely. The sansui I got from the same store still has makapal na alikabok inside, which is a better sign na di pa kinalikot i think. test the unit, if you like the sound, then its a good buy. I saw mga 6 or 7 resistors changed sa right side na pcb, the repairman said he changed the old ones with compatible resistors, malamang same resistance, so it should be fine. I noticed another thing, sa may speaker connector sa loob, there's one square device na parang napalitan na, 2 kasi yon magkatabi, yung isa plain grey in color lang, yung katabi nya nanduon pa yung brand, not sure kung napalitan din ito.

The sansui 907 limited seemed nice esp. since it is a "limited" edition model, but i found a little too old for my liking and plus the fact it was relatively underpowered compared to the 907X. However, a cd player can be connected to it through the aux port.

Looking at my Sony, the only things bad about it is that the tone controls won't work (it doesn't light up). But overall it seem to be in better shape than my Luxman. The Sony had no dents, the front and back panel almost like new and the wood panelling had some scratches.

Need help from the Amp gurus, my plans is purchase another Luxman but a higher powered one and probably a Sansui Alpha series. What is the model to get for a Luxman? Would the LV-117 be considered good? Can't seem to find a historical model line up on the net.   

Also if you were to choose between a Luxman, Sansui Alpha, and Kenwood L series, which would you get? I plan to consolidate to only an amplifier to be used to listen to vocals, jazz, etc..

id go between the luxman and sansui anytime sir.

same with me even if the sansui or luxman amps were older, or 20wpc RMS less powerful than comparable brand models. also, the gold-plated or no CD outputs are no problem for me (outside of phono, they're all line-level anyway). most good performing amps fall short in faceplate/backplate cosmetics. defective tone controls should not be a factor too. if you're using tone controls, it simply means you haven't optimized your amp-speaker combination/placements. for optimized systems, tone controls degrade sonic quality. this is generally true for high-end amp-speaker matched combo.

I don't use the tone controls, but it doesn't hurt to have it repaired by them while its still under warranty.

How much are the normal asking price for an amp in the pier? They quoted me like P8K for the Sony TA-F555ESXII initially and I tried to haggle and haggle with them. Eventually they gave it at a lower price and wont budge further after. I wont post the price, it seems a little too high for a Sony or a 300 watts amp.  :-[ Btw, this is the place with lots of speakers outside.

For the Sansui Au-D907 limited they initially quoted it as 6.5K for a 260 watts amp, I think the sony 333ES was going for 6K. How do I know if i'm getting dupped?

Post by: sandawa on Jun 17, 2004 at 07:36 AM
sorry. napansin ko sa ilang posts ko para akong nagsusulat ng memo hindi ko napansin forum nga pala ito. anyway, tone controls aren't bad but eventually you wouldn't use them when you found the ideal setup, which is relative to a lot of factors especially your room. and you're right, it's better to have a perfectly working unit esp. if it's under warranty. also, let your listening preference prevail instead of those of guys like me.

i have friends here in davao who are into trading surplus consumer electronics and they have told me their secret. for amps, look at the power consumption at the back. Japanese shippers ask for P10 per watt now, so a 300-watt power consumption rating at the back means the unit was bought at roughly P3,000. the add-on amount, varies from brand to brand and external/internal appearance. a repaired unit would be priced higher since additional amount was spent on it. in the past, before demand rose there in Manila, the asking price per watt was only P5. so, start haggling at say P12/watt and go up to P20/watt if the unit is something you fancied. it's guaranteed they'll already have decent profit at P15/watt. of course, this is a supply-demand game thus my info may not apply at all when the deals become "fast and furious."

wow thats very useful info.... thanks sandawa.

i know that place with the stacked speakers, that's where i bought my sony 333es and sansui alpha707.... their asking price are usually much higher than other stores, so if i can find those units elsewhere i would spend more time walking around.... for instance they asked for 5.5k for the 333es but i found the same amp elsewhere with asking price of 4k.... but the cheaper amps i found were in much worse condition so i haggled for the 333es to around 4.8k by saying that the other store had 3 of those all selling for 4k (which was true).... same thing happened with my sansui, they asked for 6.5k at the time, but apparently they smell the blood rushing through my brain hahaha so i only got it down to 5.5k.

gotta haggle with that store they seem to expect it from buyers so they jack up the asking price.

Post by: sandawa on Jun 17, 2004 at 12:28 PM
Just been to a Japanese warehouse/junkyard here in Davao and found out radical changes in their prices to retailers for "as is" AV units. Here it goes:

1. Amps: black - P12.50/watt maximum of P4,000; silver - P10/watt maximum of P3,000 per unit
2. CD Players: big - P500 to P600; medium - P350 to P400
3. Tape decks: big - P1,000-1,100; medium - P800 to P900
4. TV: 28 to 31 inches - P2,500 to P2,800; 32 to 34 inches - P2,900 to P3,500 (obviously the high figures here apply to widescreen units)

Last February, I bought two Onkyo CDs there (C-501XD and C-901XD) at P1,000 each. Napamahal pa pala ako. Take note that the rates apply to "as-is" units and only about two-thirds of these are in good condition. The risk of getting an unrepairable unit could go up to 33%. But internal arrangement could be made like what I did for my almost mint-condition Onkyos.

If I only have enough time, I'll open a channel so I could send units to you based on these prices. If you guys could incorporate an audio club or a formal group with dedicated one or two staff, maybe we can explore a "cooperative" type trading channel for the benefit of members and give those pier retailers competition. Also you could organize weeked auditions for new gears from high-end dealers there, get hefty discounts too, through such audio club.

parang ganyan ang sakit ng accuphase amp ko..... mahinang scratching sound lumilipat ng kaliwa kanan, minsan nawawala ang tunog sa isang channel...... mahirap hulihin ang problema, like recently i've been using the accuphase for 4 days straight without problems since the CDP shootout and kagabi ko lang ulit narinig yung kamot..... pero sandali lang nawala din ulit.

try mo painitin muna ng 5minutes yung amp before playing anything..... it seems to minimize the problem.... i suspect its in the power-on relays, bcoz one time when i turned it and while waiting for it to warm up, i heard the relay click more than once, and then it kept clicking in 10sec intervals until i started playing the amp.

or baka madumi lang mga contact points ng amp mo.

Kuha ka ng stick ng barbecue (stick lang ha, walang barbecue) then open your amp and let it play. Gently tap the caps on the channel where you hear the "kamot", konting tyaga lang at makukuha mo yan.

from what i'm reading here, wa-is na ang mga members dito mamili. pretty soon many would start regular weekend home-based audio trading, like what i did in mid to late '80s in QC. the urge to unload starts when one sees new must-buy units but he has accumulated at least a dozen equipment that are inactive. kung mainit ang mata ni misis (dahil baka hindi makabuo ng panganay - talking from experience), no escape - kailangang magbenta!

ang problema, you have competition from the pier and from the forum. maybe you should begin exploring an orderly marketing arrangement. otherwise, your re-sale prices would suffer. bad for forum members, good for outsiders.

wow great prices over there...... if only the pier stores would sell at that price i would probably have more stuff to play with...... maybe CDP / amp tweaking will become thriving industry....... i guess our prices are higher because of the higher demand..... i wouldn't mind spending P500 on a CDP and risk an opamp upgrade.

was hoping someone would open the channel on the Manila side, maybe someone who already has an audio store, but i guess doing so would kill their brand new products so its not practical for them..... maybe someone who already has a surplus store?

You guys seem to be developing a series of love affairs with amp hardware.  One after the other.  ;D   

Sir AV, these "inexpensive (surplus)" amps (i wouldn't say "cheap" dahil derogatory) offer a practical and exciting option especially for low-budget guys like me. to paraphrase forrest gump: it's like a box of chocolate, thus, the element of surprise exists. also, i'm sure you remember good old Wynn's Audio in Kamuning (near Phoenix Records, those good old days!) back in the '80s where a 100-watt amp would cost P5k. that amount was about 3X the starting pay for a fresh graduate back then (i started low kasi medyo bobo, maraming bagsak). now that amount, also quoted even for amps with higher power rating, is only a third of a fresh graduate's starting pay.

you're right in our previous post exchanges . i asked the traders here in Davao and most of these units came from recycling plants in Japan, as "junks." the good ones come from garage/community/auction fairs. the repairable ones or those with minor problems are shipped to nearby low-income countries so poor audio enthusiasts like me could have a chance to buy premium models (like my Alpha 907) that never reached our shores during their prime. if i were doing a term paper, or even a thesis, i'd work good on this phenomenon. ang dali nito. i'm quite excited over this development, i'm sure you're also amused.
Title: Re: Surplus amps
Post by: av_phile1 on Jun 19, 2004 at 01:12 PM
Yup I recall Wynns.  I also recall Sam's Audio at Magallanes where I got my used Sansui AU-D11.

It's always fun engaging in a collecting hobby.  Coins, stamps, jewels, toys, guns, miniature models of anything, cars, houses, wives...oops  ;D  Collecting not only can yield gems once in a while, but is a real hands-on learning process of what went behind it and its history. 

Far be it for me or anyone to stop you from doing what gives you fun, I just hope you don't get sidetracked from the real goal of the Hi-Fi playback pursuit and the philosphy behind it.  It's the RECORDING we want to listen to.  Not the player, amp, speaker or the room.   ;D 

Ofcourse those gears allow you to listen to the recording. The more transparent, accurate and neutral the gears,  the better to reveal what the recording has, for good or for worse.   But  they are the MEANS, not the end. 

I know those surplus amps at their prices can give value, something that shouldn't be missed.   And at those prices, the urge to collect and compare can be compelling.  I just hope once you find the amp that really gives the best value for you, that's it.  Otherwise, when and where will it end?.  There will always be better amps at the pier next month or next year, right?    Or will you be in a perpetual cycle of buy and dispose, buy and dispose?  Or just fill those shelves with so many gears so you can choose depending on your mood?  And in the proccess, you could miss out on the many wonderfully recorded stuff for which life is simply too short to listen and savor.  :(   But if you can do both, well and good.  Just my thoughts.
Title: Re: Surplus amps
Post by: sandawa on Jun 19, 2004 at 02:15 PM
true. and i would also advise the others to upgrade their software. there are a lot of audiophile-quality materials out there that could be bought at reasonable prices. chesky, linn, clarity, sheffield, mobile fidelity, reference, absolute sound, sony, etc. but you see, even getting more technical, such as equipment tweaking, is towards achieving the ultimate sound, or a previously unheard sound, we want to achieve and discover.

Sir AV, i guess we were luckier we had built a good collection of audiophile-grade recordings, incl. vinyls that were easily available then, but hard to find now. remember Danny Samonte's (Sam's Audio) record sale on Pasay Road in early '80s? i was a fresh graduate back then, but i was able to buy at least a hundred vinyls from that little shop. i shifted a bit to CDs, however, after a guy at the Linn shop on Union Square in SF in mid-90s demonstrated that digital CD technology has improved a lot since the early '80s.

my interest in audio was on-and-off and i once thought i had settled on the best i could afford. however, i don't think my desire to upgrade would ever stop. call it human frailty, but i'd say some others would feel the same. the gear is nothing without the music and only good amps and speakers could do justice to the lush orchestration of Mahler's 5th and the grandeur of Beethoven's 9th. your posts make this forum a lot more interesting. thanks for your comments.

After Wynn's and Sam's Audio, nawala ang used amp market. Lahat mahal na, lalo na yung high-end 2nd-hand amps ni Manny Lim sa Audiolab Timog. At least ngayon bumalik yung used amps, more powerful at even lower prices. I dubbed a lot of their CDs too, tapos biglang nagsara dahil sa dami raw ng utang.

Far be it for me or anyone to stop you from doing what gives you fun, I just hope you don't get sidetracked from the real goal of the Hi-Fi playback pursuit and the philosphy behind it.  It's the RECORDING we want to listen to.  Not the player, amp, speaker or the room.   ;D 
. . . .

Ofcourse those gears allow you to listen to the recording. The more transparent, accurate and neutral the gears,  the better to reveal what the recording has, for good or for worse.   But  they are the MEANS, not the end. 
. . . .


i totally agree with you sir av_phile1...... i understand when you see someone accumulate hardware like i do, one gets curious if the guy ever spends anything on Music :-\ ... i'm happy to report that its the music that keeps me from buying more gear; if i weren't buying CD's i probably would have bought more hardware than i have space to keep them :-X ... i remember having the urge to get at least 4 more different models out of curiosity -- a kenwood, victor, sansui & denon :o ... but a trip to my "suki" CD store always puts a stop to that. ;D ;D ;D ;D

i once contemplated opening a thread on "What do you do to contain your SARS?"...... and my first contribution would have been to get the price of the gear you like, and use half that amount to buy CD's..... the enjoyment you will get from listening to 5 new CD's using your old gear will be much greater than listening to the same old CD's on newly acquired gear..... (most of the time).

but if i see a higher model than the ones i have now, i would still upgrade to it and dispose old one.  ;D ;D

Anyone using modern banana plugs to connect to their surplus amps? I noticed they can't seem to fit right into the hole of the speaker terminal of the surplus amp. The hole in modern amps are 4 mm wide while the hole in the surplus amp was like 1.5 to 2 mm only.
Any remedies without having to look for another set of banana plugs? 
Title: Re: Surplus amps
Post by: sandawa on Jun 22, 2004 at 11:40 AM
Dyan pumapasok ang crimp-on pins, usually bended shape, available from Monster Cable or even Quantum and other brands. Same quality (ang problema sa MC malambot ang gold niya kaya madaling mabali) mas maliit sa bananas, pero gold-plated pa rin at mas mura - about half the price of solid bananas. Actually, mas flexible ang crimp-ons compared with bananas and spades dahil puwede rin siya sa spring-type terminals.

is there a crimp-on pin that is compatible with a banana plug? As in, I could just insert the crimp pin on a banana plug. So i dont need to remove the banana plug and insert the crimp on pin whenever I need to use a surplus amp.

dapat may butas sa tabi yung banana plugs mo. all solid gold-plated banana plugs have a hole on the side for crimp-ons or directly, for the bare wire. there are new small bananas made in China and Japan na may butas din pero yung mga locally made na mura (yung kailangan ka pang mag-solder), walang butas yan, so hindi puwede ang crimp-ons.

sir actually my banana plugs has three holes. One is where the speaker wire is inserted and secured by way of a screw type clamp. The other one is meant for other banana plugs to be inserted on top, (for bi-wiring). The last one, i dont know its purpose, but from here you can see the bare wire.

Post by: sandawa on Jun 25, 2004 at 11:06 AM
for those who have bought a couple of surplus amps already, i would recommend that the next step be to buy a good preamp, preferably WS tono. after some disappointments, i finally got my first tono last wednesday from s2kov who shipped it to davao without hassle (fund transfer online was also instantaneous).

i separated the pre and power sections of my Alpha 907 and Accuphase, hooked it, did the A/B same-volume tests, "no epek" on sounds for both equipment! i prefer the built- in preamps of Alpaha and Accuphase which were a bit robust on the middle and a tad cleaner on the lows. but when tono was linked to my surplus amps, Yamaha CA-1000III and Kenwood KR-7400, and on the Sansui 907F (by loop dahil walang amp in), hanep ang lumabas. parang yung MF-A120 ko, in terms of clarity, na na-doble or triple ang power. pati mga lumang speakers ko naging pogi.

That's because the tono preamp already has sufficient gain in the output stages.  If I recall right from the wiredstate site, it has a gain of 12, making a 1volt input come out 12 volts at full volume to drive a low powered speaker by itself.     Line level input expects at the most a 2v input.  Some are 1.2V to drive the amp at full rated power.   You are effectively overdriving the integrated's line level input if you didn't use their main-in jacks.   Using the TONO at the line level stage, you have an apparent doubling of power because your integrateds become loud even in the 8 or 9 0'clock volume position.  And anything louder is always perceived as something better.  But don't let this prevent you from enjoying your new toy.  ;D

If I only have enough time, I'll open a channel so I could send units to you based on these prices. If you guys could incorporate an audio club or a formal group with dedicated one or two staff, maybe we can explore a "cooperative" type trading channel for the benefit of members and give those pier retailers competition. Also you could organize weeked auditions for new gears from high-end dealers there, get hefty discounts too, through such audio club.

good idea, sandawa... i could organize a cooperative with juridical personality in accordance with the Cooperative Code of the Philippines... that is if you guys would want to formaly organize an audio club with at least 15 memberships.

good point AV. but it in my case, as i mentioned, the comparisons were at same-volume levels, by adjusting the variable and fixed outputs of the CDP. that's the beauty of CDPs with two or three sets of analog outputs. that should eliminate gains' deception, as you warned, no overdriving. clarity, in reference to my Musical Fidelity amp, was not present on my other Jap surplus amps while the doubling and tripling of power, as perceived, is due to the fact that my MF only has 40wpc while the Jap integrated amps i'm coupling with tono have over 100wpc rating.

my conclusion? tono may not be as good as the pre-amps of my Accuphase 302 and Alpha 907, but it's better than built-in pre-amps of my other units. i'm almost sure that would apply to others too. it'll be under observation for two weeks. if it still sounds good, i'm planning to honor it by buying a real high-power amp, could be an Altec Lansing 9444B (300wpc -professional series), to get an auditorium feel in my room.

sir akyat ,

ok, yung kay sir wanderlust di pa yata tapos.  :)

sir punk kid,

ok naman tunog ng hk, mataba nga. bagay din sa onkyo speakers.
iba yung amp sa picture. black yun sa akin. wala na ako nakita hk dun, here the website sa specs.

parehas ba ka slim ng hk6100 mo yan?
Title: Re: Surplus amps

masarap yang new find mo sir ah, benta mo na lng yan sakin, hehehe.

d pa tapos amp ko, d kasi ma isolate ni sir tony yong source ng unbalanced l-->r volume, e ok naman daw laht ng parts.

anyway, yong kay DOHbert sold na, wla na tyong sansui 907 entry nyan. d na rin ba sya lalaban?
Title: Re: Surplus amps
Post by: D0Hbert on Jul 08, 2004 at 01:13 PM
Syempre sasabak parin padre :) Quiet lang ako kasi wanna test this amp first before isalang natin. Mukhang ok sya for the shootout. It's a Sansui AU-D907X Decade. Its a later model than my old D907X, doesnt use torroidal transformers anymore, but according to the Japanese guy I correspond with, mas ayos yung transformer ng Decade, tapos nag improve ang sansui sa NFB ng amp, noise feedback yata yon or whatever its called. Besides, this one is a limited edition and its the last of the 907X series before the alpha was released. Mas yummy :P

Diatone is Mitsubishi's audio brand. Mitsubishi had a good reputation in US amp/receiver market before the yen appreciated starting in mid-80s. Before Fostex, Diatone also had the best Japanese audiophile-grade full-range speaker. I've read on the net a few years back some old-timer audiophiles in US and UK were still looking for old Diatone full-range speaker units which I've heard were good for tube amps.

Post by: RU9 on Jul 16, 2004 at 08:22 AM


good point AV. but it in my case, as i mentioned, the comparisons were at same-volume levels, by adjusting the variable and fixed outputs of the CDP. that's the beauty of CDPs with two or three sets of analog outputs. that should eliminate gains' deception, as you warned, no overdriving. clarity, in reference to my Musical Fidelity amp, was not present on my other Jap surplus amps while the doubling and tripling of power, as perceived, is due to the fact that my MF only has 40wpc while the Jap integrated amps i'm coupling with tono have over 100wpc rating.


Hi Sandawa,

Will you please elaborate on the above statements. I have a Tono Preamp/Rotel amp combination. At 9:00 volume setting, maxed out na siya. How will a CDP avoid this problem.
I am planning to buy a CDP, what specs should I look for?

Thanks.

I just bought a surplus stereo amp (from a fellow pdvd member) and am currently using this with a Philips 727k DVD player na may built-in DD/DTS decoder. While the set up gives good audio/stereo performance, i would also like to enjoy DD/DTS sound while watching home video.

The 727k has a 5.1 DD/DTS output. I'm planning to connect the center output of the player to the TV, the front L & R output to the present surplus stereo amp and i'm planning to buy a second surplus amp (i prefer a pro-logic amp) for the surround L & R channel (hopefully this will give a left, center & right surround sound). The LFE (.1) to my active subwoofer.  I wanted to enjoy both worlds (the pure audio and the home theatre), do you think this idea of mine is worth pursuing.
Magkano kaya sa pier ang surplus na prologic amp.

IMHO, the prologic amp will not give you separation of sound from left and right channels because it only produces mono sound (coorect me if im wrong). i would rather recommend a 3 channel amp like av_phile's set-up to pwer up your center and surround speakers.
Title: Re: Surplus amps
Post by: sandawa on Jul 16, 2004 at 05:53 PM
Pro-logic is two channel-based but it processes sound from those channels to get simulated center and surround sounds. It is somehow similar to the old David Haffler-surround technique where you connect the negatives of two surround speakers, then connect the remaining two hot wires to the left and right channels of the amplifier. The result would be left channel minus right channel sound and right channel minus left channel sound coming out through the two surround speakers. I think av-phile could explain this better. Btw, another possible result of the Hafler sound matrix technique is an inedible fried amplifier since impedance could dive to 2 ohms.

Anybody tried using universal remotes for your stereo surplus amps like Onkyo, Denon?  What brands and models do I have to look for?

I saw this Sony universal remote at 5th Avenue in Alabang Town Center which can be programmed to control stereo amps.  Costs P650.00.  The guy said that it can only work for models '91 and up.  Any suggestions?
Title: Re: Surplus amps
Post by: sandawa on Jul 19, 2004 at 04:06 PM
even cheap China-made (generic) universal remotes could control Japanese consumer electronic products - from TVs to amps, CDPs, etc. meron nga lang limitations sir, such as power on/off, volume, and index (song selection). okey na rin, kaysa wala. prices of such universal remotes, however, could go down to as low as P120 (here in Davao) in Chinese bazaars.

i am now using the remote of my yamaha rvx-495 to control my surplus technics cdp, this remote is i think within the category of universal as it has programable keys for specific units, e.g. dvd player; cd player; md/tape; etc.

i think at raon you cn have a uni remote for half the price you qoute.

Baka may kwento kayong maganda tungkol sa power supply stage ng mga sansui amps anong technology ang nakakabit dito. ;D ;D

Title: Re: Surplus amps
Post by: akyatbundok on Jul 21, 2004 at 02:24 PM
ang balita ko from andrew sevilla of phasetron is that sansui used to be a manufacturer of power supplies, kaya yun ang specialty nila at nag carry over sa amplifier products ang expertise nila dun..... suggestion nga niya kung gusto namin ng magandang transformer para sa tube amp, mangahoy kami ng surplus sansui amp, dahil "annealed" daw ang bakal ng transformer core nun, na bihira na gawin ngayon.

ang balita ko from andrew sevilla of phasetron is that sansui used to be a manufacturer of power supplies, kaya yun ang specialty nila at nag carry over sa amplifier products ang expertise nila dun.....

Sansui used to be a power transformer manufacturer after WWII, kaya talagang nandoon ang galing nila. If you open your Sansuis, especially the Alpha series, the toroidals have the "vintage" description on them. That's because the company took power supply design seriously, could be patented, a la Krell. Alpha 907 amps have weights ranging from 28 kgs to 35 kgs, I think, approximating the heft of Krell's low to middle models. I opened my Sansui Alpha 907 and Accuphase E302 just last week and the power amp designs of the two were very similar to Krell's. Accuphase's power caps, however, are really big - three times those of Sansui's although my Alpha 907 has four, dalawa lang ang Accuphase. Sabi ko nga kay Sir Akyat sa PM, yung sa Accuphase parang specialized audio but industrial grade - mukhang mahirap maghanap dito sa Pinas para ma-repair ang unit niya. Biro lang, Sir!

Sansui also started with tube amps, like other audio old-timers, but shifted to SS. Their chief designer in the '70s was fascinated with the old Sansui tube sound, so, he tried to alter their amps' circuitries starting with the first 907 in mid '70s to mimic the sound of the tube amp (sayang meron dito sa Davao na original AU-907, P3K lang last month, hindi ko pa binili agad, naunahan na naman ako.) This time, it's high-powered (unlike the old Sansui tube power amps) and without the hum even at high volume (which is a problem for many tube power amps). This is the same path taken by Dan D' Agostino of Krell and Bob Carver of Sunfire (formerly of Carver Corp.). Carver's expensive Silver Seven amp is tube but SS-sounding amp, which some said is even sonically better than the famous (or infamous) Ongaku valve amps that retail from $100,000 t0 $300,000 per unit.

Good AM mga guys

I have just hooked up my surplus Pioneer A400X (from pier) with my Chario Speaker and it seems that it match with this speaker, a well balance sound stage for me compare when I'm using my Onkyo TX SR600 but it need some time to warm up about 30 minutes then okay na. For more improvement  balak kong palitan yung power cord niya and also need to buy new speaker cable since yung kanyang binding post terminal don'accept the banana type.

BTW my set up is here in Macau China, pinadala lang ng brother ko itong amplifier dito sometime in Jan 2004 but the unit was used with Wharfedale Crystal 10. According to him this amplifier produced the purest sound since don't have treble and bass control.

Smaller filter caps have faster charging times than bigger ones - the better to respond to peak current requirements in dynamic musical signals.  So theoretically, four paralled 4,700uF is better than two 10,000uf caps.  Sansui must have implemented this to some advantage.
Title: Re: Surplus amps
Post by: sandawa on Jul 22, 2004 at 04:01 PM
could be, but i guess the use of power caps is also dependent on the characteristics of the toroidals and the design of the power amp's circuitry. but yes, Sansui's engineers surely have good reason for their setup.

...regarding bracketing, i dont think that's necessary... habol naman natin to compare how they sound (regardless of wattage) para buyers can decide where they will spend their money di ba? i mean what's the use of finding out that a certain hard to find 80watt surplus amp sounds better than a NAD C320bee kung hindi naman makakabili nun?

amp to amp lang, wala na bracketing... suggestion ko lang yun, syempre call din yun ng magshoo-shootout kasi miron lang naman ako eh ;D

i dont think the surplus amp shoot-out will push through, almost all players ahve back out already, i myself did, with my luxman for that matter, but i however have a sansui aud907x decade, prevoiusly owned by dohbert.

sir audioslave,

most surplus amps we have are above the 100wpc  category, i think at below 100wpc you will have very few if not none at all competitors, i however recall BGA's having 2 amps (one is HK i think) having below the 100wpc output.

but i do subscribe to this proposal of sir vince.

meron palang Pioneer A-400X dyan sa pier?
guys, A-400 is an award-winning british-designed int-amp
sabihan naman nyo ko kung may makita kayong A-400 sa pier.
thanks

meron din dito sa davao surplus Pioneer A-400X -  P3K to P4K - and yes it's a good amp as per British mags' reviews pero mababa ang wattage (excellent in its class, but not comparable with high-waattage amps that also got excellent reviews) kaya medyo hindi mabili dito. outside of those reviews, if you look at its built though, front and back plates, you'll know it's a well-built amp.
Title: Re: Surplus amps
Post by: audi0slave on Jul 28, 2004 at 03:28 PM
A-400X is different from the A-400. the latter model is designed in UK while the former is the japanese version which is the later model but miserably failed to surpass the accolades given to the A-400.

Title: Re: Surplus amps
Post by: sandawa on Jul 28, 2004 at 03:35 PM
Hifi Choice April 1994 gave A-400X a "Best Buy" rating for amps with prices ranging from 300 to 600 pounds. i still think it's a mid-level unit considering Sansui Alpha 707 was selling in UK at that time at roughly 1,600 pounds.

OK lang yan... NAD amps are known to conservatively rate their amps and even if their amp's power output is just pegged at 80wpc, it is a high current output approximating or even surpassing other amps' conventional rating of 120wpc.
Title: Re: Surplus amps
Post by: akyatbundok on Jul 28, 2004 at 03:38 PM
psst wanderlust, nasa iyo na pala yan decade ni dohbert..... hehe congrats ha.

hey guys, i can host the surplus amp shootout pero let's limit the protagonists to around 4 different brands so we can still listen to a 5th amp, preferably a current model... may i nominate:

1) audioslave's NAD C352
2) bga's Yamaha AX-1200
3) wanderlust's Sansui AU-D907 Decade
4) seacrstmd's Kenwood L-03
5) bga's HK or Denon PMA-780D, or nels76's Sony TA-F333ESX

the highest surplus models in terms of original price are nos. 2-4.... i understand iceman's concern about availability, what's the use of having a shootout if we can't buy the ones we like anyway?  if i may add, surplus units of the same model have different mileage so even if you find a similar model you still have to deal with its condition, does it sound like its supposed to?  i guess the benefit would be: if anybody would like to buy/sell one of the candidates in case the owner is hit by SARS hehe.  ;D >:D :'(

that will be great, by it the nad can easily compete with most surplus amps.

sir akyat, kaw na bahala sa groupings ng amps. Group A, Group B, Group C etc. para kahit ilan ang entries, yung top 2 per group lang ang makakasali sa next round. :)

title ng shoot out... "solid state integrated amp shoot out" para walang distinction on whether the amp is a current model, pre-owned or surplus - whether stock or modified. but if modified or tweaked, dapat i-disclose yung mga mods done on the amp.

For Sure since si pareng akyat ang host, speaker
to be used is the MS908.

Suggestion naman po for the Following:

- CDP to be used
- CDs to be played
- IC to be used.

pano ba ang switching natin among the amps? Tanggal-kabit na lang ng IC
between the CDP and the amp?

Dalhin ko pa ba Sony ko? Eh mukhang heavyweights iyong mga kalaban. :-\  :'(

let's play more CD's than we did last time.... we have 6 amps so we can play them up to 1 hour each.

problem is we can't have them turned on all at the same time baka mag-overload ang electrical outlets ko sa laki ng power consumption.... ok lang ba sa inyo yung pa-isa-isa?  turn on one amp at a time and disconnect & reconnect cables everytime.

bale sir i realize pala hindi tayo nakakasiguro kung sino makakapagdala so ilalagay ko na lang sa list as soon as mag-confirm yung owner.... inuna ko na kay benjie dahil sabi niya nasa kotse na lahat ng amps hehehe..... i think we can compare 5 amps at a time, even 6 amps if we start right away.

i think its better if we listen to all of them first, then decide which ones will advance in a final comparison, pero dat means we all have our own list of top contenders.... what ya guys think?

Bro pag kila akyat sigurado mga 1 pm ang start minsan umaabot ng pass 6pm kung matapos. Eto yung last na sumama ako sa session sa kanila but that was 4 sessions before.  Lately ata with the intro of AMX amps mas tumatagal ang session kila akyat.

Palagay ko sabay tumataas naman ang kunsumo ng kuryente ni akyat dito . . . .  Bro wala bang entrance fee sa session  O0

Round 1 in no particular order:

1. Yamaha AX-1200 - surplus
2. HK PM-645vxi - surplus
3. HK PM-6100 - surplus
4. Denon PMA-780D - surplus
5. Marantz PM-50 - surplus
6. Sansui AU-α707 - surplus
7. Gainclone dual-mono - DIY
8. Gainclone tube-buffered - DIY
9. Accuphase E-305 - pre-owned

whew!  ang daming amps.... masasabi ko lang wala kang itatapon, thats why its so hard to dispose of just 1 amp, pati yung kaisa-isang forsale ni bga was pulled out of the market dahil may tinatago palang tamis.... kung gaano kahirap pumili ng top 3 mas lalong mahirap pumili ng bottom 3.... kasi paiba-iba kami ng kanta at sources hehehehe.

there was a suggestion to include the top 3 of round 1 in the next session.... kasi baka tamad na tayo mag final round since narinig na natin lahat..... so parang "oldies & DIY" yung theme ng round 1, and then round 2 is "oldies/DIY vs. new production amps"...... what you guys think?
Title: Re: Surplus amps
Post by: kid on Aug 02, 2004 at 12:33 PM

Title: Re: Surplus amps

Round 2:

1. NAD C352 - new production
2. Rotel RA-971mk2 - new production
3. Rotel RA-02 - new production
4. Hafler XL-280 - 80's pre-owned

5. Round 1 top 1
6. Round 1 top 2
7. Round 1 top 3

?. Rotel RA-980BX - pre-owned
?. Sansui AU-D907 Decade - surplus
?. Sony TA-F333ESX - surplus
?. Luxman L510x - surplus

medyo kulang pa tayo ng variety sa new generation.

guys, baka gusto niyo na rin lubusin ang shootout at isama na natin ang mga separates at hybrid, tutal nakasama na yung hybrid gainclone ni master jojo.... lagyan lang natin ng price ceiling, so yung [hafler + contodo] ay pasok na rin kasi nasa price range ng mga new production amps sa list..... kung ganon eh pasok din ang [kenwood/thx + contodo] ko bwehehehehe.

Mga sirs (who attanded the shoot- out),

Pwede po ba malaman who's the best or at least the top 3 performer or at least a review of the strenght or weaknesses of each amp. At least bahala na yung reader. Kasi iba iba naman ang taste sa music ng tao.

Request lang naman po. If somebody is kind enough to share their experience hearing all these amps played. Not everyone of us is lucky enough to be invited or joined the session. And even if the host wants us all to be there, hindi rin naman lalo pwede yun.

Thanks.

i think bgavi's yamaha ax-1200 stood out as expected..... it is remote-controlled (motorized), so it has all the features of new production amps; smooth silver finish and glossy side panels looks elegant; and most of all it sounds musical & muscular at the same time.

john's non-inverted dual-mono gainclone was the smallest and lightest amp, but it had incredible bass -- fast, deep and detailed.

jojo's hybrid gainclone and bgavi's denon 780D were musical in the mids and highs.

just my impressions from very short & informal listening.... we were using all kinds of combinations: 2 CD players, one external DAC, a tube buffer...... it is possible that my impressions were of the source and not of the amp.... plus we played songs on one amp and not on the other, so it was very informal.

personally i am very much intrested with the yamy, a friend who heard it once before was quite impressed and he said that malambing daw tumunog.

Sir Akyat,

Thanks for your brief, honest and may I say safe reviews or comments. I'm sure most of the contender are good sounding amp too. The good and fun part is you were able to listen to all of it.

Kailan kaya ibebenta yung yummy na amp na yun.  Joke lang po...

Sir Akyat baka later on if I have the fund to buy a surplus amp pwede ba ko mag-consult sa 'yo.

Thanks...

ganyan yung model na nakita kong binaba sa container van last week dito sa davao. champagne-colored pero may wood sidepanels hindi pareho ng nasa picture sa Japanese website. problema hindi pa nalalapag sa semento naka-reserve na raw. kung davao galing yan, dapat may mga kasamang new high model ng Sony amp and two newer ESD model CDPs, karamihan champagne-colored, plus meron pang iba - kung hindi ako nagakakamali yung Marantz 1150 (1975 classic Superscope - collectors' item) kasama rin sa batch hindi ko na maalala sa inis.

bat parang ang mahal na ng mga asking price sa pier ngayon. siguro alam na nila tong thread natin kaya nag price increase na sila.

sir jojo,

 makinis yung onkyo medyo mahal lang asking 6.5k . :(

yung denon mahal din asking 8k   :( :'( :'(

marantz asking 6k  :(

Xactly! I know how to learn my lesson from my past experiences - lots of money spent on surplus and new amps and still nowhere to go! After I hear my own DIYed GC sound incredibly hi-end on the cheap but multi-awarded 8.3. Not looking back anymore. Now all my surplus amps will undergo a major surgery - GC transplants!  ;D

hi,

Sighted today sa raon.

1. Surplus Marantz CDP CD-650, 2.5k asking

2 Surplus Sansui AU-X1, int. amp. Included sa niji list. ang mahal 9k daw :o

 ;D

sirs, i got this from another forum. im now having second thoughts for the sansui in raon.

Quote
I was a Sansui sales representative from the mid '70s to mid '80s and am very familiar with the AU-X1. What you said about it being "too sophisticated for its own good" is about as right-on as anything. The main problem had to do, oddly enough, with its "Super Feedforward" design, which was its main selling point. Since the SSF circuit was very stable in the AU-919, the engineers decided to try overkill in the creation of the X1. It was the unit's extremely high slew rate that caused it to oscillate at just about the drop of a hat, which always resulted in the output transistors going up in smoke. I found out the hard way that just about anything could trigger the unit into oscillation, including RF interference, connection to a speaker comparator, thin gauge or "resistive" speaker wire (this amp really NEEDED Monster Cable or Live Wire to work best; forget about "zip" cord) or even a speaker system with a less-than-flat (read that "easy") impedence curve. I also found out that one must NEVER power the unit up without speakers connected; it would blow up. Usually, leaving a headphone plugged in would prevent this from happening. When it did work, however rarely that might be, it sounded GREAT and was certainly the best transistorized integrated amp that ever came out of Japan (did A-B comparisons against the top Pioneer, Kenwood, Technics and Onkyo integrated units of the time; the only unit that came close was the AU-919 running in "bypass" mode). It was during one of these comparison tests that one of my associates decided to buy an X1. A couple of years and four sets of output transistors later, he sold the unit. He felt it was too unreliable. From the repair angle, my technician absolutely HATED the X1. According to him, each of the six demo units that we were running had blown up at least twice (this is where we discovered all the "don'ts" about this amp) and some as many as four times. He was glad that we did not sell that many units but did average an X1 every other month (for the same reason!).
I hope this helps. As repair parts are becoming increasingly difficult to find for the X1, I would recommend that you consider selling yours (assuming it still works) and, if you are still partial to the sound of Sansui amps of that era, consider getting an AU-919 (still quite a few floating around eBay). When a 919 is run in the "bypass" mode (a front panel switch), it is one of the sweetest sounding amps and closely rivals the X1, without all the trouble. It does significantly reduce the power (if memory serves, it bypassed the entire line stage and fed the power amp directly) but you will be rewarded with exceptional sound AND reliabilty.
If I may be any further assistance, please email me.


thanks...

Nice piece and good you shared this with us. But then, I thought the problerm with transistors in Sansui was true mostly on the A series amps and R series receivers which were cheaper. I've been a die-hard Sansui user and I remember technicians in Sansui's service center in Soliven Bldg. in EDSA/Ortigas complaining about the Sansui models (mostly components of complete systems) sold here as "sirain." My problem Sansui though during that time was my SD-1330 tape deck and a Z series compu-receiver, newly released back then.

I had an AUD-7 and -9 and G-5700 back in the '80s and I had no trouble with them despite roughly a decade of use. I was able to sell those units at relatively high prices. I have now two 907s, including an Alpha, both running on SFF  and still no problem. My old 907, tries to mimic the mid and high characteristics of the tube, but short on low while the Alpha I'd say has the balance I need - specifically filling up the punch and deep low I want to hear.

Anyway, your info on the weakness of the Sansui (is it limited to X1, or to others with SFF too?) is really appreciated. It pays to know technical things like this.

Oscillation is an amps silent killer.  ;D

I remember destroying 4 perfectly good power transistors in a prototype just because my input wires came too close to the output wires. Pufff... and the magic smoke appeared.  ;D :o

This could be related to the subject of surplus amps getting very expensive nowadays. Had a chat with a trader here in Davao who deals directly with Japanese suppliers claiming they're having a hard time getting good models from recycling centers in Japan due to strong competition from Vietnam. While the Japs ship 2 to 3 container vans of surplus gears weekly here in Davao, up to five ships (dozens of vans per ship) full of surplus home electronics go to Vietnam every week. Japanese suppliers claim Vietnamese traders' offers are higher compared with those from local traders.

Of course, there's always a possibility of a conspiracy among traders and that they're monitoring our posts. Both surplus and brand new equipment retailers could benefit from higher pricing for "cheap junks." In any case, response should be rational, which could mean sort of a boycott - Aray! Internal na muna ang bilihan para mabawasan naman ang stocks nung iba diyan na para nang tindahan ang kuwarto. In the meantime, we could concentrate on promoting and learning from mods of local talents like JojoD and the others. Tailor-fit pa sa preference natin ang tunog.

i totally agree with you on this sir!!!  my fare share in the surplus market, are : a sansui and a luxman amps,  plus a technics cdp. am actually thinking of adding another cdp and a lower powered amp (for the rm)  but have decided to put it on hold for the moment as prices of surplus, specially for amps have increased to stupendous highs!

agreeing with you further sir is your proposal to go the DIY alternative way of life, i actually have been toying with the idea of auditioning one of masta jojos GC as an alternative to going all tubes(for the time being, killing SARS) but havent really gotten into that as the tweaked cdp is the yummier option that i am eyeing now.

but hey, with the surplus amps going as high as 9k id rather have a DIY (which i guess wouldnt cost that much) which will surely have a  guaranted after sales service and a possibilty of upgrade and tweaks pa, to your own liking and specifics. ;)

so i say! a boycott is it for me, for now on the surplus market. >:(

good riddance. ;)

Good AM mga guys

I have just hooked up my surplus Pioneer A400X (from pier) with my Chario Speaker and it seems that it match with this speaker, a well balance sound stage for me compare when I'm using my Onkyo TX SR600 but it need some time to warm up about 30 minutes then okay na. For more improvement  balak kong palitan yung power cord niya and also need to buy new speaker cable since yung kanyang binding post terminal don'accept the banana type.

BTW my set up is here in Macau China, pinadala lang ng brother ko itong amplifier dito sometime in Jan 2004 but the unit was used with Wharfedale Crystal 10. According to him this amplifier produced the purest sound since don't have treble and bass control.

 OFC Speker wire with ferrite rings

wow!!!!

looks very professional sir! the power cord looks like that of an XLO (which i think cost more than 10k) and the speaker wire if i may say: impressive! easily outdones expensive speaker wire in looks.

so hows the performance sir? wish i knew how to dress up mine to.... ;D

Thanks bro for your comment .....it takes time also to assemble all those gear need to check every store here in Macau since nakakalat dito yung mga electronics shop and in addition hirap makipag communicate since they dont speak english. need to get picture in internet and print then show to them so they will know what I want.

Regarding construction I just consult some DIY audio tweaks sa internet.

The result was very impressive, it seems you are listening to a tube amp...a well balance soundstage....bass is tight but deep...... sulit lahat ng gastos at hirap...

Kung kaya ko gumawa nito kaya mo rin.....just have the right materials and guide from electronics guru (audio tweaks in internet) then you can make it.....

hmmmm your words inspire sir..... though i dont have a know how on this matter as i am in a field much different from this hobby of ours, but maybe a reading from the gurus, consultations from diy friends here, and i little luck, il build mine as well in the near future.

may i now start the ball rolling by asking for your help sir.... re: the power cord for the amp as i have been long planning to build one for my cdp and amp. for the cdp my prob is the socket as the cdp socket only admits the small to hole size, standard for cdps and other smaller elec. equipments, and the fact that in most amps  the power cord is permanently attached, how do i go about it sir?

we might be OT so if ever pa pm na lang din sir.

This is not OT but I remember Dau/Clark, when I was just starting back in the '80s. That's the equivalent of Pier now, where you can get surpluses including small-item military-grade spare parts for fighter jets, satellite-based equipment, latest model tanks, etc. at junk prices (caps at P1 to P5 each and wires at P1 to P10 per meter.).

Those items, I was told, were best for audio DIY upgrades. The traders would insist those were superior (made to save lives, even a country, as objective) compared with commercial-grade parts. Got caps back then that replaced dried up parts of my Quad and other old amps and the results were okay.

An engineer from Eastern Telecoms who bought my Quad amp whose huge power caps I replaced with military-grade ones swore low frequency has improved if based on same model Quad that his brother-in-law owned. I also used DIY interconnects back then including tiny pure copper wires from jet fighter wire assembly which I braided for my old ARs, Bose, Infinity and JBLs (got into British speakers only in the early '90s).

But I got tired of those wires after about 10 years of use in mid-90s since they looked ugly and my wife didn't like them, so, I went back to Monsters' latest, such as Navajo Whites and Interlinks. But I still keep those military-grade ICs in my house outside the city. My braided wires (10 covered wires each of high-grade pure copper) I remember, were 6 meters long each. I'll probably install them back, pag na-inggit ako sa mga experiences ninyo.

Kung inabot mo yung golden days of Dau, Sir, magsasawa ka ng parts para sa amps and audio DIYs mo. Nakabilao ang mga eletronic components parang sa palengke, iba't ibang kulay, grabe ang mga brands meron pang Martin Marietta (yung gumagawa ng rocket papunta sa buwan) - at may mabibili kang piyesa na dalawa singko!

Wala na yung hinahanap niyo, kasi the amps, electronics, etc. used to be in shops at the junction of the old superhighway/Dau exit. The last time I passed by that junction 10 years ago, nandun pa ang structures pero no more shops as well as goodies. Siguro nga ang available yung mga hinihukay na lang.

I recall Dau to be a mecca of sorts for the military-grade electronics parts that probably were canniblized from the US miltary bases.  I used to work in an airline at their maintenance base and, boy, the parts to repair avionics equipment are really robust, and very expensive.

Those were the days. My Dad's American friend once took us inside Clark's off-duty commissary where prices of audio equipment were only half of those listed in Stereo Review (equivalent to a third of brand new prices here). Isang section lang, para kang nasa Best Buy sa dami ng home electronics!

You're right. Lockheed and Martin used to be separate companies that merged dahil wala nang giyera. Also Martin and Marieta used to be two distinct companies, both defense suppliers. Ngayon, may giyera na ulit, buhay na naman and US war industries expect its economy to boom soon.

Not sure but I think Lockheed specialized in aeronautics while Martin's forte was avionics before they merged (after Martin-Marieta). Sana gumagawa rin sila ng amps and other audio equipment para mas masaya at hindi tayo OT dito. Ngayon, hanggang pulot/hukay na lang tayo ng piyesa nila.

I saw some new arrival amps in pier yesterday.  I saw Sansui Alphas, 707Extra, 607i, 507i, 307i, Luxman A-007(40Wx2), Luxman LV-102(65W x 2 which I bought), Yamaha A-8, Yamaha AX-800.  Sansui Alpha707 was being offered at a steep price of 8.5K or 9.5K i think but didn't bother to haggle.  new arrivales were mostly tape decks and speakers.  I didn't have more time to roam around since it was already 6 PM and the shops were nearly closing.

happy hunting.

@wanderlust
thanks sa info bro...


mga sir i have questions regarding  this surplus amps... malaki po ba difference ng sound quality compared sa multimedia speakers like logitech z680 or altec lansing 641... i mean, if i will hook the amplifier to wharfedale 8.1 ano po ang magiging standing nya compared sa logitech z680 or z5300 in terms of sound quality..

i am a total newbie when it comes to hi-fi audio so i came here to ask those people who have auditioned those speakers and compared it to some hi end multimedia speakers like logitech z680 or altec lansing 641...

medyo confused din kasi ako... i have a budget of 10,000 for multimedia speaker and before i was ready to get the logitech z5300 for 10500...... until i saw this thread.... :-\

worth it po ba kung z5300 na ang bilin ko or should i aim for a surplus amp/wharfedale 8.1 setup? gusto ko kasi sa speaker eh yung merong punchy bass...( tight bass yata equivalent nun sa hifi people heheh...) and clear highs...
kaya po ba ng wharfedale yung kind of bass that logitech z5300 delivers?

please help, i am familiar with lots of hi end multimedia speakers pero pagdating sa hifi eh newbie talaga ako so i dont have an idea on how it compares...

thanks....

mga sir i have questions regarding  this surplus amps... malaki po ba difference ng sound quality compared sa multimedia speakers like logitech z680 or altec lansing 641... i mean, if i will hook the amplifier to wharfedale 8.1 ano po ang magiging standing nya compared sa logitech z680 or z5300 in terms of sound quality..

sir, malayong malayo ang home amp/speaker combi compared with multimedia set up - on all frequencies: from low to high - even if you buy top model Altec or JBL multimedia speakers. unless, you use your PC as source by hooking it to an amp with a good pair of speakers. you're right, audition is the best way to do it, kasi iba't iba ang pandinig natin as well as musical preferences.

i agree with sir sandawa..... they hifi speakers and multimedia set are worlds apart so much so that it will be quite difficult to make an apple to apple comparison, but anyway let me just state the obvious and based on tthe little experience i have had before:

1. multimedia are rated at pmpo's while hifis normally wattage;

2. normally, the former are self powered (meaning plug and play type) while the latter normally needs an amp, reciever to work;

and from previous experience (i owned a cheap 2.1 multi media speaker once before and a self powered creative multi media speaker)

3. for the creative (using the standard PC connection) highs mids are difficult to make out, insufficient bass;

4. for the 2.1, no mids are missing to much bass sound gets muddy after almost six months of use i have to crank the volume all the way up as it doesnt sound as loud as it was before;

5. and for the little auditions i had with altec (not the hi-end new models thought), over all i think the sound is more comparable to a mini component, bass emphasized.

hope this helps a little, still let your ears decide.....

Well, my ideas for this mini-amp is it can be used as a pc amplifier, potable cdp (discman) amp, ps2, coiupled with my infrasonic parabolic microphone you can hear conversations up to 25 meters (so long as you have line of sight), and other wonderful applications.

salamats po sa mga info sir...

sa sobrang curious ko eh pumunta na ko sa pier and dun ko nalaman na malayo nga agwat ng hifi setup sa multimedia set up.. kahit yung hi end ng logitech eh sa tingin ko malayo difference in terms of clarity.... meron kasi nag audition dun....yung setup nila eh onkyo integra ( di ko matandaan yung model pero rs yata yung huli) and surplus na speaker... hehe! hanep ang tunog!, parang totoo yung drums and cymbals... ano pa kaya kung brand new hifi speaker nakakabit dun....

one more thing na napansin ko sa tunog ng onkyo amp na yun eh di masakit sa tenga yung treble, da best ang clarity... yung altec lansing ko na ATP5 pag medyo mataas na ang volume eh di ko na madistinguish yung mga instruments...

at dahil dito,  i decided to make a surplus amp/bnew speaker setup instead of buying logitech z5300 for 10500...

tanong ko na din po kung ano po marerecommend nyo between these,

Onkyo Integra A-817XX, A-819RS, ... yan lang kasi natandaan ko na models doon....

Title: Re: Surplus amps
Post by: kid on Sep 15, 2004 at 09:27 AM
with 8.1 setup, you'll need a sub if you want to achieve deep bass.

halos parehas lang naman ang tunog ng surplus sa new production amps. i suggest you look for hi-current amps such as harman kardon becoz wharfs speaker daw ay hard to drive. just keep us posted and will try to help you.

narinig ko na pareho, ibang-iba ang tunog nila.... must be properly matched with the CD player and speaker.

relatively, yung 819RS parang naka-equalizer na smiley face, mas malakas ang bass at treble.... yung 817XX mas flat ang frequency response so mas labas ang boses ng singer.

suggest ko demo the amp with ur speaker.

sa 10k ba sir ay kasama na yong amp and cdp dyan? if not kasi youll have several choices either new, pre-owned, or surplus, with the latter youll have enough "sukli" for a surplus amp. but i humble suggest that if your planing to get non-surplus speaker better get the pre-owned ones..... and also youll have less trouble waiting for the break in period for you to hear what your speaker can really do.

you also have to consider the music you prefer listening with, and as punk said youll need to get a sub of you want to achieve deeper bass,specially if youll be getting a bookshelf, extra cost din iyan. basta wag nagmadali bro, take yuor time, audition.....

sa amp naman do the same thing, read the surplus amp thread first before you get yourself one, guaranteed youll never go wrong if you cme to the pier prepared and with a specific idea in mind.

if you intend na pang matagalan na set-up mo, i suggest you get the niji listed amps.... mas mahal pero mas sulit (for onkyos the intergras are there top of the line models) , sir akyat is the expert on this naman.

tnx for all the help and suggestions.... da best talaga pinoydvd..!

If I have your money, I will do my hunting this way. Get 8.3 (mga 8k) or 8.2 (mga 6.5k) speakers. Then I will hunt the midi-type amps - the likes of SONY, Sansui, Technics etc. They are rated as high as 150watts in the plate and they are sold for 2.8k wala pa tawad. I have tested the technics (SU-*840 something) / sansui (AE70 model yata) models with my 8.3. The best so far that I encountered in these ranges is the Sony (I got an AX-22 which is my main music amp, connected to a TT). They are very good. These type of amps can drive wharf no sweat.

This way, you can get started investing in a speaker, the best of wharf (8.3), and have an initial amp that can drive it effortlessly and enjoy your music and movies without any subwoofer. Then upgrade your amp later if you get the itch again.  ;D The 2.5k for amp is not much to give up after a year of use, and you can sell it also later. But  am warning you, you might not want to give it up.   >:D

yep,  Diatone is the Audio "arm" of Mitsubishi, and though it is not as active as it was in the 80's , specially with its speakers line, the most famopus of which is the Diatone P-610.

there are plenty of daitones speakers sa pier as sir obet has mentioned, there are amps as well.... i recall seeing a good looking one 2 months ago, but like sir obet has not auditioned it... sadly.

Mukhang maraming Japanese esoteric amp models na pumapasok lately. Finally got, early this month, a replacement for my Yamaha B-70 power amp (early '80s). It was a Yamaha B3 power amp (mid-70s) that looks like a long black solid brick (6X6X14) with huge cooling fins on side walls, poging tingnan at bagay sa WS Tono dahil halos magkasing lapad sila. Ang tunog? puwede na, pero mas pino at malinis ang Accuphase at mas mataba ang Alpha 907.

Also got an Integra P303 preamp (mid '70s) at giveaway price last week. It sounds sweeter, yet subdued, compared with Tono - good for hours of loud-volume listening. It's of minimalist design, limited to volume control and selector buttons for phono, tuner and tape. Nothing more.

Palagay ko kung dadalasan niyo ang bisita sa Pier may makikita rin kayo diyan na weird looking audio. Sayang din, lalo na kung mabigat (sinaksakan ng isang damukal na piyesa at bakal ng mga Hapon para gumanda ang tunog at maibenta ng mahal) at mura pa. Kung hindi maganda ang tunog, pang-display na lang, para hindi talo!

now with this latest development, maybe its now time to rekindle that love affair....

The Yamaha B3 was a replacement from a unit that I decided to return to the store where i got it three months ago. I did not ask for a refund, instead I told the owner I'll just get a replacement when I see something equivalent to P5K, the amount I paid for the Yamaha B70. Mali ako sa specs ng B3: 8X8X16, about 15kgs and fuse is 6 amperes at 240volts (walang nakalagay na power consumption, wala rin akong makitang specs sa net) tingin ko, mga 100 to 150wpc rms lang ito, mas may muscle yung Alpha 907 sa tunog, 160wpc yun.

The Onkyo preamp was bought at only P300, kasi walang pilot lamp (power indicator). Bumili lang ako ng 12-volt lamp sa tindahan @ P11, kabit na. Binuksan lahat, conclusion: sira ang ulo ng mga Hapon, may mga sections pa na sealed - parang top secret circuit design considering this model was about 30 years old now. Ang napansin ko, kadaming filter. I was attracted to it because the silver faceplate says "The Ultimate Stereophonic Preamp", tapos walang tone controls, only volume, three buttons, at balance.

Pag may napunta sa inyo dito, sasamahan ko sa mga junk shops ng Davao. Kailangan cowboy, marumi ang damit para puwedeng maghukay!

pre hindi yata normal yun, dapat completely silent pag walang signal.

yun sa fren ko A-817XX baka hindi pareho sa A-817XD so i'm not sure how it sounds... better if u audition it with your speakers using your own CD's para alam mo kung gusto mo tunog o hinde sir.

Post by: sandawa on Oct 08, 2004 at 12:55 PM
mga sir tanong ko na rin po kung normal lang sa onkyo integra yung popup sound pag initial power on... para kasing masisira ang speaker....

dapat way down, or zero - depende sa scale used - ang volume knob mo pag nag switch-on ka. kung may umingay pa rin, kailangan mo na ng WD-40 para sa switches. kung meron pa rin and it lasts a few seconds, may problema na ang capacitors mo. if that happens, isolate the pre and power sections to understand kung saan ang defect. A-817 is equivalent to A-8170 (US model series). That's rated 80wpc rms, good enough for a starter in hifi and could produce big sound on efficient speaker.
Title: Re: Surplus amps
Post by: wanderlust on Oct 08, 2004 at 12:58 PM
i agree, i really am quite unfamiliar with that model, infos will only just be figures, if youll like the sound then no matter how un exciting would be the info you have gathered on it, it really wouldnt matter, now on the otherhand kahit ba mapaka impressive yong specs e d mo naman gust o tunog wala rin yon. let your ears decide bro.

i dont think its normal, as far as i know, the only audible sound youll hear when turning on an amp is the minimal click, not a pop-up.

i've decided to post what happened to me today, which is comparatively "malas." anyway, it could provide some lessons especially to newbies who are now into surplus hifi.

i picked up a used Yamaha B-4 power amp yesterday for P5K and had it opened for inspection and cleanup just this morning. problems emerged after the cleanup: two of three indicator lamps were dead thus had to run to an electronic shop for two 12-volt lamps. a lamp costs P10 to P12 each. i installed the lamps and everything looked okay until i noticed one channel was silent.

made some connector changes until i found it was the right channel of the Tono preamp. a resistor was disconnected from the common/ground post due to a loose female RCA. that twisted the resistor tail resulting from frequent cable switching. i soldered the resistor back and tested again. still, no sound on one channel despite a new round of cable switches. then, i found how stupid i was. one spade on the speaker terminal was pulled out probably while disabling some connectors on the power amp.

that robbed me at least three hours but it's still okay. sometimes, quirks like this make this hobby much more interesting. the bottom line for the newbies: don't get scared when problems like this crop up - this should be expected for getting into surplus hifi. it's part of the fun. learn to use the soldering iron, and be aware of basic parts to replace, and how much these cost. you'd save a lot that way than depending on technicians that could charge you a lot of money for just replacing a fuse.

"parang may bagong kabayong sumisipa sa kuwarto mo ngayon ah. mukhang may binili ka na namang JBL diyan, o Sansui kaya?" may wife commented. "hindi, nag-modify lang ako ng amp ko, may natutunan kasi ako sa PinoyDVD website," i replied. "akala ko may binili ka naman, just to remind you 2nd sem enrolment na first week of November," she said. aray! that's equivalent 6 to 10 good surplus amps.

Yamaha B-4 was mean, rated at about 120wpc (B class) and 40wpc (A class), the company said it produces double that power due to its "X-power source circuitry" whatever that means. i let my ears be the judge though. it's a lot more powerful than my "good-looking" B-3 amp, or even my sweet sounding Accuphase, and approximates the sheer power of ther Sansui Alpha 907 (160wpc).

sandawa,

i also encounter that problem when i bought a suplus tuner. after a week of use, the light bulb of the LCD was busted. when i opened the case i saw a replacement bulb and thought that it was thrown away by the owner due to that problem ;D then i started to heat up my soldering iron and replaced the lead.

after long research in the forums, i finally bought this surplus amplifier.... ONKYO Integra a-817xd
hanep ang tunog! swabeng swabe, i can listen to this for hours without headache! kaso sa typical sony ref style speaker ko palang nasubok... i dont know kung ok ang tunog nito sa target kong speaker which is wharf 8.1... ok rin po ba sa 8.3 to?

btw im into music listening so dun sa mga nakasubok na ng 8.1 and 8.3 i need your comments... pls.. if ever kayanin ng budget eh pwede po kaya ang monitor audio b2 dito?

one more thing, talaga po bang hindi umiilaw yung servo operation LED ng ONKYO... di ko rin kasi alam kung para saan yung indicator na yun....

Hi sandawa,

Talking about the Tono preamp improving the sound of surplus amps. I recently tried to connect Tono preamp to the equalizer connections of my Pioneer int amp. I think Iceman mentioned this before but using an AVR.

Int amp equalizer out --> Tono preamp in
Tono preamp out        --> Int amp equalizer in

This is a far better connection. Now I can play LOUD without the music being muddy.

For an integrated amps that has no external connector between pre-amp and power-amp, this is indeed the cleaner way of enjoying the tono pre-amp - (now functioning as an "equalizer"  ;D).

For those amp that has the external connector, the ideal connection is still the tono pre-amp to the power-amp-in. The pre-amp of the integrated amp will become idle in this sense. This makes less stages for the music - theoretically cleaner.

Of course, it might be different for other people who is still not satisfied with the sound the latter setup produce. The earlier setup has another distortion component added (being three stages already) - but who cares if the sound can be appreciated anyway.

I have this set-up, Tono Preamp to a Rotel RB-03 amp.  At 9:30 Tono vol. setting, distortion is already present.  A component mismatch according to Rene.

Also tried Tono preamp to CD-IN of Pioneer Int amp as suggested by early users of the Tono.  Sounds impressive but fatiguing and boxy sounding in the long run.
Title: Re: Surplus amps
Post by: sandawa on Oct 18, 2004 at 12:21 PM
i have a problem with Tono pre-amp being hooked as an equalizer, which it is not. connecting it in between an active pre-amp and power amp of a surplus amp could render it useless although it could solve volume control problems for some setups.
what would happen is you'll be feeding Tono with the signal coming from the built in pre-amp of your surplus unit. it could even degrade the sound coming out.

assuming Tono is superior than the built in pre-amp of the surplus amp:
a.) built in pre-amp of surplus unit reduces fidelity coming from the source by 2%
b.) Tono reduces fidelity by 1%

that setup would technically reduce sonic quality beyond 2%, whereas the reduction would only be 2% if the built in pre-amp is used (without any other equipment on the loop) and only 1% (best setup) if the Tono is used with the power-amp.

aHobitt is right on the ideal setup, which is using Tono straight to the power amp.  for surplus amps, this means using the switch at the back of the unit and connecting Tono to the power amp jacks.

but then again, if the sound coming out of that setup is okay with you, don't let this opinion bring you down. let your ears be the judge.

Post by: wanderlust on Oct 18, 2004 at 01:20 PM
i am a tono + ss user also, and i have the tendency to agree with sir sandawas observation, however i do not limit my connections to the main outs alone, had tried cd direct, cd, aux, etc..... in the search for the best connection for my set-up....  eventually it all boils down to what your preference, after all it is you that listen to your systm all through out.
Title: Re: Surplus amps
Post by: aHobbit on Oct 18, 2004 at 03:26 PM
Obviously, RU9 used his ears!  ;D

And it is probably mismatching (of tono-out and power-amp-in) which can cause some fatigue-causing listening strain. I could have brought this matching thing up in my previous post, but decided to avoid more complicated discussion.

As I said, the ideal connection is "theoretically" recommendable. It is entirely different thing to hear it for yourself.

I agree with some "audiophiles" that sometimes, it is the distortion that we run after. Who would not want to hear very beautiful music from bad recordings?

Distortions may sometimes be the magic to make something listenable. Or should I say good distortions.  ;D

Let's give our ears a break - decide the listenable - and enjoy the music.  8)
Title: Re: Surplus amps
Post by: sandawa on Oct 18, 2004 at 03:50 PM
i would agree. i just got a surplus Onkyo preamp, containing up to 5 kilos of filtering electronic components, which makes bad recordings listenable. outside of that, i've been consistent in my belief that sonic preference is something personal that couldn't be dictated by anybody, not even by so-called audiophiles.

a drunk prize-winning playright and poet once yelled at me during a drinking session at Trellis: "I don't care care if the music is coming from a transistor radio or from your expensive hifi system. All I wanted to hear was Paul Simon's guitar."

Hi!  I did a set-up with my friend who had a pair of 8 ohm bookshelf speakers in his sala and a pair of 8 ohm cube speakers in his foyer all connected to the Speaker A and Speaker B inputs of his Marantz surplus amp.  After 3 songs running both speaker A and B, the amp was really hot.  Fearing that it would break down and thought there was a problem with the amp, I replaced it with a Sansui surplus stereo amp and connected them speakers to the amp.  There were no problems for 4 days until suddenly the amp just shut down and no way can it be turned on again.  I ran through the system and didn't find anything wrong like a possibility of a short or something. 

Possible problems:

1. AVR- amp is connected to a 1000W AVR in 110 volts.  This is a brand new AVR...possible uncontrolled voltage in the AVR(?).  Jap amps need to be plugged in 100V as said in the back of the amp.  Would this cause the problem?

2. Speakers- 2 way bookshelf 120 watts 8 ohms, cube speakers 60 watts 8 ohms both running as speaker A + B.  My Jap friend told me that it is ok to run speaker A or speaker B but not Speaker A + B.  It might have caused the problems of the amp.  Is this true?

3. Amp- 2 amps bogging down in the same set-up(?)  I am now using my Luxman stereo amp in 220 volts.  Fearing it might follow on the same fate.  Hmmm.....

Need help gurus...anyone?

Thanks in advance!
Title: Re: Surplus amps
Post by: akyatbundok on Nov 16, 2004 at 07:19 PM
doc, i think running both speakers A and B at the same time means that you are running 2 speakers in parallel,  which lowers the impedance load down to 4 ohms (possibly lower) and therefore the current demand on the amp is increased..... that's probably why at the back of the amp they suggest 16 ohm speakers when connecting both A + B so that the total speaker load is still 8 ohms..... with two 8 ohm loads in parallel, and each speaker probably going down to 4 ohms on bass passages, you get an average load of 4 ohms and occassional dips down to 2 ohms, which can be considered unsafe for an amp rated for 8 ohms nominal.
Title: Re: Surplus amps
Post by: sandawa on Nov 17, 2004 at 08:44 AM
i fully agree with Sir Akyat. using 2 pairs of speakers is risky especially if you're using the amp longer than usual and at higher-than-normal volume. impedance is not constant and even speakers rated at 8 ohms could eventually go down to 6 ohms, or less, on low-frequency passages. with 2 pairs of speakers, the impedance rating dives to 2 or 3.

that's the reason why some amps have 2 ohm ratings since these were made to remain stable below 4 ohms and could be used for commercial applications. many audiophile power amps though accept only one pair of speakers. i believe your Sansui has been damaged, it's prone to problems like that. getting too hot, however, does not necessarily mean something is wrong, since class A amps are designed that way.

There are conditions when you can use A+B speakers - that is, you have to somehow control the volume of the amp in such a way that your amp will not overload - and this you will note by the heat the amp produced.

You did not mention model of the Sansui amp. I have some of these models, and it can detect shorts or overload and can shut the whole system or just a channel, and will activate it again after powering it off and then on again.

You may also check primary and/or secondary fuses inside the amps.

Post by: sandawa on Nov 18, 2004 at 09:35 AM
in such cases you can still save your amps and could mean replacing just a couple of fried transistors. spare parts cost should be from P500 to P1K per amp if sourced from Raon. i have used more than half a dozen Sansui amps already, and currently have AUD-907F and Alpha 907 but never had such problem even if i sometimes use four speakers simultaneously. but in the '80s and '90s, even Sansui's service center at VV Soliven admitted A and R amp/receiver series (Sansui models starting with those letters) frequently suffer from that problem. happy listening, Luxman is quite good in making amps.
Title: Re: Surplus amps
Post by: wanderlust on Nov 19, 2004 at 04:37 PM
i see  the sansui as a very reliable amp, i personally own a 907, and have abused it quite alot, i even triggered the protector mode to be activated (i havent really figured out why, maybe one of the speakers was out of phase) a couple of days ago but thats just it, after i turned it on again its up and running  n namn.... quite a sturddy amp i say. heat is always at tolrable level though when in operation even if left playing the whole day tru....

i also opened it and took several pics of its innards, most part were premuims as i see it, will post the pics soon.

I think not. Most of their integrated amps starts with A (as in AU) and perhaps the receiver starts with R.
The fact is that the later '70s and 80s international models are not manufactured as good as the Japan local counter models.

But if you got something surplus from japan, wnderplus is correct in saying they are built well.

Of course, it is entirely different issue if the pier guys already make some repair work in the said unit.

I have one 607XDecade, fed with 2-8ohm (4-ohm equivalent) per channel and power a big open hall at musical performance level with audience of about 200. Some people commented we have indeed good-sounding powerful sound gears.  ;D No busted thing. Powerful sound gear at 4000 only.

At one time, a channel do not have a sound. A check reveals a short circuit on the speaker side. Fix the short at speaker side, put off the 607XD, and power it up again. Case closed.  ;D

The Sansui amps sold here back in 80s and 90s as brand new units start with A not AUD, AU or Alpha, such as A50, A60, A80 etc. Yes, these are international models that are inferior in built and were mostly released as components to systems. The receivers sold locally also start with R as in R5, R7, R80, etc. These were the models with tin covers at the back.

Sansui's good quality amp models in Japan start with AUD but almost always 07 as last numbers, with 907 as top of the commercial line. It was also AUD in the US, except they do not end with 07. Quality of those released in US suffered when the yen strengthened against the dollar starting in the mid '80s. Sansui's high quality receivers start with G and Z and not R. The Rs were the cheapos.

My two 907s and about half a dozen other AUDs in last 20 years also use super-feedforward technology but I never had the problem with them. The relay system in these amps work and all you have to do is switch on and off your unit but if it doesn't work anymore, burn-out likely occured due probably to shorted speaker wires and diving impedance below 4 ohms.

sa Sansui Alpha series malaki na ang binding posts, pati butas, kahit Cavendish banana papasok. maganda sa Sansui, sir, wala nang bagong lumalabas kaya yang mga luma, bound to be collectors' items, lalo na kung well maintained. ang objective ko ngayon lahat ng makita ko dito sa amin na Sansui 907 bibilhin ko. after 10 years, pakakawalan ko (hoping the caps would still work, or else i'll replace them myself).

yung mga nakakuha ng high-powered AU series decades ago, suwerte dahil sa US daw, sabi ng utol ko, mas mataas pa sa original (brand new) price ang bentahan ng mga surplus 40-yr old AUs (rated 80wpc and up). ganun din yung mga surplus Marantz, 60s designed by American founder Saul Marantz. sama na rin yung mga 70s Luxman power amps, when that company pirated Tim de Paravicini (Alchemy, EAR) as designer back in early '70s. Tim left Luxman, I think, during the mid-70s to launch his own high-end brand in England. ano sir, simulan mo na rin? pangatawanan mo na yan!

yung high-powered Sansui models ang mataas ang demand sa US, hindi yung maliliit. ang dumadating dito sa atin na AU puro low-powered. hanggang 40 watts RMS lang ang nakikita ko dito sa amin, ewan ko diyan sa inyo sa Pier.

i get your point on inflation and i admit mine is not a win-win formula - there's good amount of risk involved. but i'm thinking more on enjoying music from these units, especially if each costs an equivalent of only a few days of work and my passion for collecting does not upset my finances. the nice thing about it is i could dispose these units even after 10 years without much depreciation. 907s are rare even today, by the way.

if prices of Sansui AU premium models even appreciated in US audio market, that could also happen here especially the 907s- it depends on supply and demand. it's not all ears for me. i also factor in economics in this hobby.

this is a very intresting if not tempting proposal sir.... buti nalang i already own a 907 series (model), though not an alpha, it is still a hard to find edition. i did saw several alpha models here but had second thoughts on getting it as they are low powered and relatively not well known.

im hoping i could get 1 though.... someday, keep my fingers crossed.  ;)

hindi toroidal yung transformer niya sir. pero okay lang, yung 907F ko ganyan din. sa anim ko na amps, dalawa lang ang toroidal - Alpha 907 and Accuphase. basta ang alam ko yang amp mo ang top sa commercial model ng Sansui bago sila nag Alpha.
Title: Re: Surplus amps
Post by: wanderlust on Dec 09, 2004 at 12:53 PM
thnx for the info sir.......... i do have doubts about this being torroidal, however, i have seen the inside of the 907x (not a decade) and it had a circular trafo... which i presume a torroidal design. maybe the decade isnt.

surplus guru,

ok ba marantz pm - 54DS? ilang watts ba ito?   

thanks!
Title: Re: Surplus amps
Post by: sandawa on Dec 16, 2004 at 08:51 PM
I'm not an audio guru, pero makiki-sawsaw lang. Sa akin, ang maganda lang sa Marantz 'yung '60s to '70s US-made, solid state or valve. Yung mga Marantz Japan at Marantz/Philips, hindi maayos ang review, mababa ang re-sale value. PM-54 (Japan) should be 50 to 70wpc RMS, pero kung maganda naman ang tunog, type mo, and you think the price is reasonable, okey na yan. Sa newer (Japan) models nila, ang maayos sa integrated amp yung PM-94 and PM-84, dubbed Quarter-A series, kasi automatic A-class ang takbo niya basta 25% lang ng RMS rating ang gamit mo, at malakas sila. On normal listening, basta walang true bass - such as acoustic or electronic organ low, we use no more than 10 wpc continuous even with low-efficiency speakers. Reproducing good clean bass requires at least 100wpc even with high efficiency speakers. Dyan magaling ang toroidal transformer design. Kung PM-74 yang nakita mo, puwede dahil 120wpc RMS ang rating nyan. Warehouse surplus price ng PM-74 dito sa Davao - P3.5K, as is (available two weeks ago). Sa mga surplus shops dito, PM-74 in good condition, P5K.

sir sandawa is right, and i wl repeat him here, but i however want to add, a few months back i saw a PM 84  being sold un the buy n sell papers for 8k, its being a surplus thought is what i am uncertain of, as there was no indication to that  effect. there were from time to time other marantz posted like pm 54.

and yes, i am not a surplus guru sir....  ;D

Post by: sandawa on Dec 18, 2004 at 08:37 AM
Gusto ko sana, pero baka mas malugi ka. Una walang warranty ang galing dito. Secondly, yung maayos na surplus amps at least 20 kgs., roughly P1K sa freight charge, tapos baka pagdating diyan pisa na. Mas mabuti pa siguro diyan ka na lang bumili, at least puwede kang mag-habol sa retailer.

Isa pa, Online-based job ako, tambay sa desktop buong araw, hindi basta makalabas except on Saturday. I'm supposed to be in Manila 1st or 2nd week of January but I'll probably bring only two CDPs, naka-kontrata na kay JojoD. Unless he doesn't need those junks to tinker with anymore. Mahirap magdala ng audio equipment, since the well-made and powerful amp units weigh more than 20 kgs., while upscale CDPs at 10 kgs. or more.

you can't go wrong by bookmarking this site: http://www.niji.or.jp/home/k-nisi/index.html.
use Altavista Babelfish to translate Japanese to English. 

many of the models shown on that site, with original prices of 100,000 yen or more ($900 and above) are among Japan's best audio issued commercially in 70s and 80s. they arrive here (as well as in Vietnam, Indonesia and southern China) as surplus/junk units. as far as i'm concerned, the quality of those units, assuming they're A-1 condition, is better than brand new units/models you buy here at P60K, or more.

if local distributors were able to get these from Japan during their heydays, they'd likely to be quoted at much more than their list prices. such was the case in UK for good Japanese audio imports. for instance, Sansui Alpha 707 in Hifi-Choice 1991 had a 1,600 pounds list price and Alpha 907 had 2,000 pounds (or over P200K). those quotes were higher compared with most of their (British) high-end models. remember that British audio sold here now comprises mostly entry to low-middle models. i bought my Alpha 907 at P8K here in Davao two years ago, Alpha 707 was available here a month ago at P4K (warehouse as-is price - could go up to P7K in retail shop) and Alpha 607, with a few units still unsold, at P5K, good condition, shop price.

Post by: sandawa on Dec 26, 2004 at 01:54 PM
same here in Davao. limited na, di tulad ng dati. pero sa liit ng market dito (1/8 ng Metro Manila population), hindi ganun kabilis mabenta ang good models. lalo na pag nakatiyempo ka ng pagbubukas ng container van, kahit wala kang plano, mapapabili ka.

sarap lang sa surplus, yung budget for one brand new unit, kayang ibili ng 10 more powerful and superior units. that's assuming these are in A-1 condition. basta may available na Jap surplus, except speakers, malamang hindi na ako bibili ng brand new.

sawa na 'ko sa mahal. my first true hifi system in 1982 cost me an equivalent of 7 months salary. i bought my MF120 at HK$5,000 and Epos at HK$6,000 in Hong Kong brand new five years ago, my Accuphase e-302 discounted (old stock) at 100,000 yen in Tokyo in mid '90s (original list price 250,000 yen). nag-sisisi ako sa Musical Fidelity, pero hindi sa Epos at Accuphase.

oops! sorry po typo error...yep its a pre amp sir.. actually nasakin na ang unit... grabe, nastock lang yata to dun sa bahay nung hapon..walang gasgas,  kapal ngalang ng alikabok..
i am currently hooking it up on my onkyo integra 817xd....

based on the site you mentioned, im happy to know that esotec series was indeed a high end model from Marantz, a rare piece...  kung meron lang sana kapares na amp to.. like yung PM-8..

pero i still have to test this... considering na 1980's pa yata to... baka nadegrade narin ang mga Pots nito...

Hello, question lang po. May budget ako na 3K, makakabili na ba ako ng matinong amp sa pier for this amount of money? Anong model/unit ang makukuha ko for this? Or should I just go for a NOS (new old stock) na NAD 310 for 5K? Eto yung specs ng NAD:

Any other suggestions?

Definitely, the NAD unit should free you of any risk involved in getting surplus amps.  But for 5T, I'm pretty sure you can get a more powerful surplus amp with specs that are no different, if not better, than that NAD.  Bear in mind that many of those surplus amps were Top-Of-The line units during their time.  It's risky alright, the chances of getting lemons are higher.  But once you get a good one, by most accounts here, it can prove to be a great value for the money.

Last I visited the pier there were many Sansui and Victor amps, with a sputtering of Yamaha and Teac brands.  It's dificult to say what's out there, you just have to visit the place as new stocks that come in are unpredictable.  Sometimes you's be lucky to spot a good one, in other times, they're just so-so.  I would suggest that you be accompanied by someone knowledgeable in getting surplus amps at the pier.  Maybe some members here would be willing to act as an advisor/guide for you.

I overlooked your room size which is above the typical.  Unless you have a very sensitive speaker in the 90+db range, a 30sqm room could require more than 70watts RMS/ch of stereo to fill it with enough headroom for clean sound.  Suggest you get a 100wattRMS stereo amp.  There are many at the pier going around 5T which you can haggle for around 4T or less.  Is this for music only?  What's your speakers?  Do you want room-filling sound? DO you play  loud?  No neighbors close by?

tanong ko lang po kung familiar ba kayo sa Sansui A-707 integrated amp? maganda ba ang review nito during her time? nakita ko to sa bahay ng tito ko at na niya ginagamet, kaya hiningi ko. dala daw to nya galing saudi sometime in the 80's. ilang wpc po tong amp na to? sinubukan ko palang gamitin, medyo malakas din pero ang lakas lang uminit. onetime nag shutdown sya sa sobrang init siguro tapos nung lumamig na ok na naman. is this a serious defect on the amp or just a normal thermal protection that goes off?

salamat :)

If i recall right, this is part of a set.  I had a Sansui A-909 for a few months in the early 80s, also part of a set that I didn't get.  The A-909 is rated 90wpc.  So I assume the 707 is rated at 70wpc.  Just can't recall if that's RMS or DIN-rated.

THis is rated into 8 ohms.  4-ohms rating for the home was quite rare in those days.   This was an integrated stereo amp that came with a separate T-707 tuner, a cassette deck and turntable - the standard ubiquitous audio systems set of the 80s.  I think the set also included a pair of 3-way speakers.

DIN is a German standard used extensively in rating gears destined for Europe.  Forgot what the acronym stands for, but it's in German.  Not as strict as FTC standard.  Similar to JETA or EIAJ of Japan that rates the amp at 1kz, one channel driven at a time.

there's a Sansui AU-D707F Extra (110 wpc) available from a trader's shop here in Davao at P4.5K. it's in almost perfect condition with wood side panels, but you need someone from here to send it to you. unfortunately, i couldn't help you with this since i'm relatively busy.

as many as half a dozen members of this forum were able to buy from the Pier in the last two years Sansui 907s (not the 907 Alpha line, which is rare and is still selling in the US at over $1K used). the price range of the regular 907 amp was between P6K to P8K i was told. but not many of the owners here would sell their 907 units considering they command a high price in eBay (from $300 to $600 used). even those that have shifted to tube are still holding on to their 907s.

Has anybody been to the pier recently? I was there a few months ago and i couldnt find higher wattage amps like Sansui AU 707 (I never hoped to find an au907). I found a few aud607 but they weren't in good condition. Kaunti yata ang dating ng surplus units from Japan. If anyone found good items from the Pier surplus area, kwento naman oh.
hintay-hintay lang sir.  I was able to get Sansui AU-D907X and Kenwood L-03a there before. 
are you really interested in acquiring high power surplus amps? OT and shameless plug ::) i'll letting go of my Kenwood KA1100SD, 150wpc packaged with Kenwood KT-593 digital tuner and Kenwood DP-8020 CD Player. PM me for your offers  ;D

check this link for the specs of the amp

Post by: Lord Foo on Jul 11, 2005 at 05:02 PM
okay...

Last Sunday i finally returned to the Pier surplus amp area (third time) with a promise to my self that I will not leave the pier without a surplus unit this time.

After checking out ALL the stalls in the area I zeroed in on two units:

Sansui AUD 707Xdecade

http://www.sansui.us/images/AUD907X_Decade/aud707x_decade_5.jpg

an AUD Sansui 707xdecade integrated amp. It was the best Sansui unit i could find at the pier and  in fact had a VERY dilapidated wood casing but its internals and front face were still in good condition. This is a 130 wpc amp (next to the TOTL AU907). It is a limited edition released in 1985 and is somewhere in between the 6th and 7th generation of the Sansui 07 series.

When I hooked it up at home to a yamaha ns1000m.... i finally understood what the brouhaha about these old amps were all about.
Now i need to replace those dilapidated MDF casing with maybe a slab of narra or kamagong plank. ( Can someone point me to where i can get wood for this? i need only 2 pieces of about 1" X 4" X 12". I still have to measure it).


i also got a

Pioneer SA9800

a Pioneer integraged amp SA9800. This is a 1976 100 wpc amp  (possibly a TOTL amp). Check out the pioneer site...

http://www.silverpioneer.netfirms.com/Integrated%20Amps.htm

however, the amp i got does not look anywhere near the Pioneer SA9800 pictured in the website. Rather it is an exact copy of the sa9900 with the macho rack handles at the back  and the speaker outlets and various outlets on the sides and not at the back.
When hooked up also to the yamaha NS1000m speakers, the amps performed well enough...but alas..compared to the Sansui 707xdecade amps....it was outclassed in all directions. It maybe due to the condition of the amp though. I still have to check out the amp in more detail.

parehong maganda yang nakita mo, but i'm biased in favor of the Sansui. the Pioneers are good for those who prefer hard-rocking amps, magaling sa bayuhan. i just got a 20wpc Pioneer SA-710 (7100 in the US made in early '70s) at P750 that sounds heavier than new production models, rated 50wpc and above, costing five figures. maganda ang tunog ng vintage amps - Sansui at Pioneer, both Audio Karma favorites - since these firms didn't rein on money they spend to produce good hifi until mid '80s.

Hi Sandawa.
The SA710 seems to be in pristine condition sandawa. Great value for the price you paid brod. Is the case wood veneer? I love wood veneer. Its a pity the Sansui's wood case is a total wreck. The SA9800 i got has a pure metal case. No wood. I saw a brochure in the AK forum showing that the amp comes with a wood case option.

About the Pioneer VS Sansui comparison, i also snagged a pioneer SX1080 about  a month ago. (from Art Flores a Las Pinas Audio collector and seller if you've heard of or met him already). It was in good condition except that it heated up  very quickly. I stopped using it until i find a solution to the heating problem. (The DC Offset measured very high and i think we need a manual to adjust it.) However, that pioneer sounded very well and can match up toe to toe with the Sansui in my opinion. But I like rock so other's may think differently. 

I think i've seen your "sandawa" handle in some of the AK posts i've viewed. Is that you ?

I guess i have the VIRUS bad. I returned to the pier area last sunday and went home with a Luxman L400.
Sabi kasi ni Sandawa, buy without thinking pag Luxman eh.

okay kaya itong unit na to?
Title: Re: Surplus amps
Post by: sandawa on Jul 19, 2005 at 12:05 PM
sir, depende sa presyo yan ;D. with prices and specs at same level, i'd pick Sansui and Luxman, or even a Yamaha over other brands. better the vintage models - '70s and early '80s nung hindi pa nagtitipid ang mga Hapon.

Postscript

jus to remind you it would be better to check the DC offset of a newly bought vintage amp para siguradong maayos, otherwise baka hindi na balanse ang channels and that could trigger the relay switch. it's easy to adjust the DC offset for each channel and i think you know how to do it since you're also active in AK. 'yung bias, medyo sensitive from unit to unit, unless the service manual is available it's better not to tinker with those bias trimpots.
Title: Re: Surplus amps
Post by: Lord Foo on Jul 19, 2005 at 01:49 PM
Hi Sandawa sir...

Oo nga...Yung thread ni echowars re: DC offset is very valuable. Reminds me of my Pioneer SX1080 that has a very high measurement. Parang prituhan ng itlog sa init so hindi ko magamit. I need the manual though to have my brother make the dangerous bias adjustments.

The L400 was selling for even lower than the Sansui AUD607 becuse the sales clerks based their prices on the power consumption with a slight upward margin since the unit is a Luxman. The unit is in good condition, minor nicks and scratches lang. No rust. Complete knobs.

I haven't checked its DC offset yet. I wanted to have it converted to 220 volts first.

Sir,

The receipt says, "Little Chatty Merchandising".  The store is just after the covered supermarket along Oca St.
In any case, I visited all the stores in the area and saw this one and only Luxman amp.  Its extremely rare according to the salesboy and is immediately snatched up. Sabi kasi ni "sadawa" buy without thinking pag accuphase and Luxman eh. hehe. He's right though, I now have two Luxman , the M120a and the L400 and I am satisfied extremely with both.

Nde naman galit sa pera pre.   ;D Three brothers kami. nakikibili sa akin ung mga brods ko din. I just use "I" instead of "we" to simplify. Besides if you think about it, i bought a Yamaha rxv740 yamaha receiver and a set of Tannoys and Energy HT speakers about two years back and all the surplus purchases i have made is just a small fraction of what i shelled out at the time. And when we're done with appreciating the surplus units, they'd still fetch a good price since we bought them at bargain prices and have consulted the likes of Sandawa as to what is of good build and quality. All in all buying surplus units is IMHO a good decision during these "economically" challenged times.

I bought a Sony CDP 333esd kanina for my brod. As you recommended in another thread, the unit is a very good one. Would you know if it can work with a generic remote control? Now i want one for myself.

foo.

pareho tayo sir, may pinapasahan din akong mga kapatid sa Maynila. yung isa binili yung Musical Fidelity A-120 at Celestion SL-6 ko last year at P18K. ngayon naman kinukuha yung Thorens 320 ko at Epos 14 ng P20K. yun sigurong Thorens ibibigay ko, pero no way ang Epos. yung batang kapatid ko naman ina-arbor sa akin yung isang Sonic T-amp/Tono combo ko. ayaw pa nila ng Jap surplus kasi halata daw na sa Tokyo recycling centers galing. buti naman, kasi mabigat magdala nito sa Maynila. my Sansui Alpha 907 weighs 30 kgs!

true about your comment on brand new vs. surplus pricing. got hooked into surplus two years ago when i found out my Sansui Alpha 907 was being sold in UK at 2,000 British pounds (Hi-Fi Choice 1994), on the other hand, an amp made in UK i auditioned in Makati two years ago sold at P60K was in same Hifi Choice at price of roughly 400 British pounds (lumang mid-level model pala binebenta rito as upscale and at original brand new price - hi-hi-hi!). and to think Jap domestic models (100V) are technologically superior compared with same models sold internationally (120V or 240V).

POSTSCRIPT:

Yes the 333ESD would run on generic RCs. if you'd have tracking problems, PM me, its trimpots are easy to adjust provided the lasers are still okay.

If you ever let go of that 907... put me at the top of your list...  ;D

Here's the post of my brod re: the 333esd versus players from China...

"I burned identical CDs.
Connected a china made player to aux1 and the Sony to aux2.
Then set tone controls to flat. The sony wins hands down.
Sony provides Bass extension rather than emphasis.
Vocals from the Sony is more real, has less emphasis but clearer.
Now i know what 'manipis ung made in china' meant."

"Tataas electric bills ko. Di nakakapagod ung Sony na pakinggan kahit walang patayan maghapon..."


I really have to get one of those ESDs for myself. Gusto ko sana ung 337esd na may wood sa sides. hay!! wishful thinking. Now I use a pioneer 566k dvd player also for audio.

Okay, the Marantz Esotec PM6 is now with my brother. I  didn't buy it before because it heated up at "egg fryng level  inordinately fast. But someone mentioned that the Class A amp runs very hot even when the amp is just turned on and is not working. Besides, the amp is not cosmetically pleasing with some parts already rusting. However, the seller sold it at half the price they normally sell a 300+ watt power consuming integrated amp.

I'll try to get some pics up soon.
Title: Re: Surplus amps
Post by: sandawa on Aug 07, 2005 at 08:42 AM
true. class A amps get very hot even without turning the volume up. the logic is that all components are "On", or prepared, when the signal comes in, unlike in class B/AB where electronic components are mostly on "standby" basis. thus, class A harnesses the amp's potential to reproduce what's recorded at high fidelity.

sir, Foo, have the DC offset and biases of the Pm-6 checked. those two generally have the solutions to amps that get too hot. there's a Marantz Esotec Pm-8 mk2 here that's worse. the problem is the biases swing radically resulting in two busted transistors everytime it's used for over an hour. can't trace where the problem is, but AK's Axel is so interested in it, he wanted me to describe everythig inside PM-8 Mark 2 for his The Vintage Knob website.

Hi guys, I've been quite tempted to join the surplus amp bandwagon after reading this thread.  My only problem is, I know nothing about the technical specs of an amp not even the terminology (am a newbie).  I did write out the models and brands of amps suggested here so I'll know what to look for at the pier. 

I wanted to set-up an audio only system.  I was actually set on purchasing a new NAD stereo amp but after reading this, I am leaning towards the surplus alternative.

Can you guys provide some tips on buying surplus amp at the pier?  Or better yet if any of you guys are planning to shop for an amp at the pier baka pwede makisabay para may expert akong kasama.  ;)

Hi Bhongskie,

Were you able to get your surplus units at the pier? I hope one of the advanced Surplus geeks in the forum went with you.

I haven't been back at the pier for a while...naubos na budget ko ...heheh. But the last time i was there, I saw a Luxman LV102 in one of the stores. Check it out pre. Luxman's are always a good buy. The unit was cosmetically in tip top shape. I didnt auditioniit though. Besides wala na kong pambili.  :D I went for a low priced bookshelf at the time and a Sony CD ES337 player.

If you haven't gone there yet. Dont get the Toshiba CDPs even if they offer it to you at a low price. namimili ung mga un ng CDs. Dont buy immediately from the stores beside the road. Check out also the stores inside the covered market. They sell at lower prices because they do not have a good location.
Title: Re: Surplus amps
Post by: bhongskie on Aug 23, 2005 at 05:33 PM
Hi Lordfoo,

Thanks for the reply and the tip!  I haven't been to the pier yet bro.  But I already had a listen to the Sony TA-F333ESX and a Sansui AU-607 courtesy of Narayan.  He invited me and a friend for a listen last Saturday at his place.  Those amps are really good.  Only regret was that we we're not abe to hook up those amps with Narayan's MS914 iba kasi naka set-up dun.  Yung 914 kasi one of my options for the speaker set.

Anyway, I'm still looking forward to joining the experts here when they decide for a trip to the pier just so I can see other models and compare them to the amps I've seen and heard at Narayan's.


Narayan,

Thanks bro for accomodating us!  Will communicate with you once I finally decide on a purchase.

Number1, a fellow forum member is I believe selling a Sony TAF555ESXII amp.
http://pinoydvd.com/board/index.php?topic=23866.20

A Sansui AuD607 is good but a Sansui AUD707 is better while the Top of the Line AUD907 is the best. Also there are versions of these amps or releases. I have both a Sansui 707 AUDGExtra and an AUDXDecade. The AUDXdecade is in my opinion much better sounding than the Gextra.

I was able to get two Luxmans at the pier at 3 thou each. You have to use every bargaining trick you know to push down the price. (That's the part I enjoy also...the haggling to get a better price.)

re speakers, okay naman IMHO ung mga modern speakers but a lot of them are now being produced in China, Malysia, Mexico etc. I've heard it said that these are inferior in quality to the old speakers made in Japan, England or the US. As for my personal experience, I have an MX Tannoy bookshelf that I bought brand new less than a year ago and I am not using it anymore. It was made in China. I have matched it with two older bookshelves i have recently aqcuired at less than half the cost and the vintage bookshelves run rings around the Tannoy. (a 32 year old Kef104ab and a Victor SX3). What I am saying is that the hunt for excellent vintage speaker is an enjoying experience in itself for me...and I save a few pesos in the process. And madaming factors to consider in buying speakers aside from pesos...your listening room characteristics, your personal taste...your other equipment.

Gandahan mo rin ung source mo sir....kahit anong ganda ng amp and ng speaker...kung mediocre ung source mo...wala din. The best CDPlayers as per advice from the gurus in this forum are the Sony ES models so I went for those units and IMHO they are right.

i've been to the marketplace... there's a good looking Sansui Alpha 707XR gold color but with a higher tag price of 8K!  The wooden (?) sides are still intact and looked good.  Haven't tried to audition though.  Sony 555ESJ was also sighted.

check it out na lang...

just sharing...
Title: Re: Surplus amps
Post by: sandawa on Aug 28, 2005 at 07:40 PM
i hope the Pier traders don't read this. that Alpha 707XR's price could be reasonable and it's worth an audition - if the unit is in perfect condition. the 707XR came out in Japan in 1993 and is rated at roughly 120 to 130wpc. it could run with ease even at 2 ohm load (very few amps could do that) up to 300wpc. it was retailed at about 200,000 yen (roughly $1,900) during the early '90s. if i were in Manila and it's in good condition, i'll buy it at that price. more backgrounder on that unit's price history: the Alpha 607MRX, a lower version of the successor series of that model, was retailed in the US at $1,750 in 1997. the US auction market (Orion bluebook/eBay) still quotes Alpha 607MRX at $600 used - about the same price as AU-X1 and AU-X11. the Alpha 707XR should cost more than the Alpha607MRX.

almost any surplus amp could do that. remember, surplus Jap domestic amps are of higher quality compared with same models they sold internationally. my impression is that these surpluses, if in A-okay condition, are even better in quality than new production amps of similar categories, Brit- or Yankee-made.

even 200wpc RMS amps hardly use 25wpc RMS (continuous). i'm using a 160wpc amp on my 60-watt floorstander and i hear better results than using lower-powered amps. usually, we use from 2 to 10wpc lang even at loud volumes (this would depend a lot on room environment and efficiency of the speakers hooked). the reason for the extra wattage is to capture the dynamics coming out of classical/orchestral pieces, especially pipe organs and other power-hungry low frequency parts. your bass shaker would easily match with 25 to 50wpc or even up to 100wpc surplus amps costing from P1.5K to P3.5K there at the Pier.

Post by: Jairus on Sep 05, 2005 at 09:31 AM
I went back to the pier last Saturday to scout for an amp (armed with the Niji list in the car  ;D and my test CDs).  After going around the outlets, I narrowed down my choices to the following:

1.  Alpine/Luxman LV101 - though this is not in the niji list, I still included this as the Luxman's are higly recommended by the gurus here.  Had a listen to this and the mids and high sounded good and clear pero parang kulang sa weight yung bass.  I'm also a bit dissapointed with its weight which is quite light and when I peeked through its grills parang medyo maliit l yung transformer niya.  Gurus, ganito ba talaga deign ng Luxman?
2.  Sony TA333ESX - Saw this inside the covered mall area and mukhang ok pa yung condition ng unit.  Asking was a bit high so I didn't bother to listen to it.  Just listed it down anyway just in case I can't find a better bargain.
3.  Sansui AUD-507X
4.  Sansui AUD-607F Extra
- Saw these last two units in the same shop along the road (I think among the shops I visited there, it has the biggest inventory of amps and CDPs).  Although, I know that the AUD-507x is the smaller brother of the much sought after AUD907x, I opted to get the 607F-Extra even if its P500 more than the 507x's price because of the following:
-higher power rating
-wood panel of the 607F-Extra is still intact
-much heavier build
-Tested both with the same source and material and I liked the 607F better.

I'm disappointed not to find a Sony ES series CDP so I settled for Sansui CDP which read all my p-disk/CDR/Orig test materials and hooked up to the 607F sounded excellent  ;D Since I got the 2 units from the same shop, I was able to haggle the price a little bit lower ;D.

I felt I had a good deal with these purchases and this was confirmed when I hooked it up with my 15-year old JVC component bookshelves.  The sound was full, the mids are clear, the hihgs are just right, and it has ample bass...I can't believe I'm listening to my old mini-component bookshelves.  Just out of curiosity, I played the same material (which BTW is track 4 of Audiophile Voices I) in my HK/Diamond 8.3 set-up and it only edged my all-surplus finds by a small margin in the bass region (which is understandble because the 8.3s are towers).

I felt especially good also about the Sansui CDP x317r (not in the niji list) because it sounded better than Denon DCD 1500 and it read all CDs so inspected it more thouroughly this time...and my, I was surprised 9and a bit disappointed) to find out printed at the back "Made in Taiwan"  ??? Anyway, did I say it sounded great? ;D

i was in the pier last saturday and i was also able to test the luxman 101 and denon pma 390 side by side with each other. ok naman pareho sa akin pakinig but i settled for the denon kasi medyo luma na masyado yung luxman and sira yung isang input terminal ng luxman.  they've got the same price btw. medyo mahal kuha ko but i still presisted kasi sabik na ako ma set-up ang baa shaker ko.  anyway  ;D happy ako

nice finds. i'm not a guru, also a student trying to learn from posts here, but i'll venture reactions on your inquiries:

1. Luxman is definitely a good brand but small/light transfo, unless a digital amp, indicates low power/cost amp. the heavier transfo usually indicates the manufacturer did not cut on cost. most of the times, heavy transfos coupled with high-power capacitors translate to deep clean bass.

2. Sony ES amps are good and still highly regarded in international audio enthusiast forums such as Audio Karma. in such forums, Jap domestic models (what we refer to here as surplus) are highly respected due to superior quality with respect to components used (affordability of the Japanese was once higher compared with the Americans')

3. the Sansui CDP you got was probably made after the original Sansui closed shop and the brand sold to other investors. the last CDP series produced by Sansui Japan, i think, were the Alpha series. don't be sad, if your x317 works well, good sound/reader, you still got a bargain.

the bottom line, however, is that you got a good deal (unless you were overpriced). the AU-D607F, rated at 80wpc, is equivalent to AUD-7S in the US distributed back in early '80s and originally sold at about $480 (retailed at close to P15K here brand new before 1985 -- $1=P25).

Title: Re: Surplus amps
Post by: Jairus on Sep 05, 2005 at 04:07 PM
Thank you Sandawa.  I'm very happy with my purchases.  The CDP is really good (despite being taiwan-made): the cd loading transport is pretty solid and stable and the entire unit is in mint condition and it sounded great.  Kaya nga I bought it agad kahit na I was bent on getting an Es series Sony.

The 607 F is also in pretty good condition with the wood panels still intact.  I opened it up and medyo madami ng alikabok and it seems wala pa namang napalitan na parts.  I didn't try to clean it yet kasi baka may masira. What is the best way to clean it ba?

My only complaint with the amp I got are the binding posts: it cannot accept banana plugs (kaya hindi ko siya na-test with my Wharfs kasi naka bi-wire ako and hassle mag kalas) and parang lumutong na yung iba plugs na parang bibigay na.  Can I change the binding posts with newer ones? Where can I have this done?  Thanks!
Title: Re: Surplus amps
Post by: sandawa on Sep 05, 2005 at 05:09 PM
i usually brush the amp's innards, then vacuum (car vacuum) the remaining dust, and WD40 spray cleaner for the connections, especially the volume/selector knobs/switches. if you can get hold of a Deoxit spray cleaner - still only available in the US i think - it's better. i think you'll be alot happier if you'll hook your 607F with your Diamond.

some members here are capable of replacing the traditional speaker terminals at the back of the amp with banana-type ones. if you have a soldering iron, and you know sources in Raon, replacement of terminals is fairly simple. in my case, i simply use appropriate Monster Cable connectors - spade for small binding posts, or gold pins for spring type - without any modification. for my vintage speakers, i did change all the terminals to banana-types.

Post by: ramble_on on Sep 06, 2005 at 08:33 AM
yup, south harbor kasi yon. but you won't see the ships up close since the place where the surplus amps are located are just about a couple of hundred of meters from the main gate.

from the manila cathedral, go straight about a 100 meters until you reach the big rotonda. halfway around it, you'll see the main gate with an arc (of sorts).

once inside the compound, concentrate on the right side (there are also a few vendors on the left side). the first section would be where you'll find sewing machines, tvs, refs, aircons. then a one story structure (most stuff you'll find here are tvs (again), china-made electronics, i counted 4 shops selling surplus audio).

you'll find the funstuff after the building. hope this helps.

good luck on your hunt.

ps i got a sony cdp esd series last saturday. found one inside the building. i saw another one in the same shop just in case you're interested.

cheers.

nice catch! i auditioned a higher model 'bout a month ago (AUD-707f) pero parang it sounded a tad shrill so i let it go, (though it could have been the speakers). i assume you got your's at chatty's also?

for those interested in another sony 228 esd; enter the one story structure via the last entrance. take the first left, count around 6 to 7 stalls on your right. seller is a fair complexioned big lady with glasses. look for the 228 on the pile immediately facing the shop entrance (it's the sixth unit from the top).

have fun!

Actually sobrang sibilant siya connected to the cdp they're using to test the unit (Victor yata?) but when we tested it with the Sansui CDP, nawala yung sibilance and naging warm and full yung tunog...so it must be the source.

Yes, got it from Chatty's.  I think I also went to the store you're referring to that sells the sone esd's..just didn't see it.  Thanks for the heads up. ;)

there was a pair of Integra 506 (pre- and power amp) sold here in Davao last year. price was P8K, power amp alone was P5K, last price from the traders. could go down to P5K for both/package if sourced from the warehouse. ngayon, wala nang dumadating. (i don't think there will be good-model arrivals in the coming months.) Integras sure look nice, but didn't have high re-sale values in Japan, based on Selword register.

Not surprised,   Many of the Luxmans and Sansui's with high resale values are no longer in prodiuction.   I think those integras are still on production since the early 80s as I've seen those VU-metered M-class as late as in last year's Onkyo's catalogue,  the front facade have not really changed much over the years.  Could this be why their earler models don't command high resale prices?  Compared to other brands, these integra separates enjoy a great audiphile standing in Japan and in Europe.

Post by: sandawa on Sep 08, 2005 at 08:58 PM
i agree that Onkyo still has a big following among global audio enthusiasts, especially in the US and Europe. but it seems to be losing its appeal to some hifi groups in Japan. here's a site that reviews upscale amps produced in the last 20 years, including US and Brit made (many Japs are also crazy over good-looking British gear regardless of how they sound):
http://tukipie.net/audio/synopsis_of_AMPLIFIER.htm

then, check this list of amp brands and models, sold at commercial-scale (not limited as in the esoteric models), that command high price at Japan's auction markets:
http://homepage1.nifty.com/Logistics/Amp/list.htm

frankly, had i known that importation of good recycled amps would slowdown, i would have bought the Integra 506 combo at the P8K asking price. another amp i failed to buy was a TA4 Nakamichi at P5K. those were simply too good to pass. i actually returned to buy the Integra 506 combo two weeks after i saw it but lost to a Protestant pastor from Cotabato.

Interesting sites there Sandawa, thanks.  The babelfish translation was a bit off and hardly understandble.  But at least the models and their prices would be a good guide if you're looking for gems to invest in at the pier mall. 
Title: Re: Surplus amps
Post by: sandawa on Sep 09, 2005 at 01:04 PM
the amp review's first two parameters i think, were on technical, and the last two on impressions, to cover accuracy and musicality. check also the way it objectively reviewed the speakers. how our favorite Brit brands/models fared vs. Jap and US counterparts, which more or less confirms what me and you and a few others were saying all along: many Jap-made equipment are superior to comparable European gear.

yes, those sites are good reference for those watching arrivals at the pier. kaya lang, latak na lang daw ang dadating dito sa atin dahil sa competition from China and Vietnam.

sir Sandawa,

question lang po regarding Sansui amps.

Which is better, the AUD 607, 707, 907 series or the AU Alpha series? What would you say are the basic differences between the two?

By the way sir... i took back the Sony TA5650 VFET from the store. Its worked at the store when tested. I haven't powered it up at home yet. I am hoping I can get a copy of the manual from Axel of Vintage Knob so that my brod can make adjustments on the bias/DC offset.
Title: Re: Surplus amps
Post by: sandawa on Sep 14, 2005 at 11:19 AM
the Sansui D series was the regular/commercial line of Sansui hifi that competed favorably with other brands in the US. it's the line that got the world market convinced that Sansui is no hifi pushover (a dedicated Sansui thread in Audio Karma is proof). the premium line during Sansui's prime was the AU-X... series which tried to recapture the tube sound, but with better specs/figures. the Alpha was the last line of Sansui premium hifi - sort of last hurray, so binuhos na ang kaya nilang gawin. since it was manufactured with the best SS components/technology, it was released mostly in the domestic market which has higher purchasing power. Europe had a few units distributed but none in the US and other markets. also the highest Alpha model sold internationally, (901, 911, etc.) was equivalent only to the Alpha 707 series. Alpha amps are quoted highly even at used market, over $1K used for Alpha 607 in the US. my 1995 Hifi Choice has a quote of Alpha 707 at 1,600 pounds brand new (it came our in Japan in 1987) and was even rated by reviewers better than Aleph Pass and some Audio Note amps. they should have reviewed the Alpha 907 series, especially the premium models, which still command an average of over 100,000 yen ($900) used in the Japanese market. the Alpha 907 (original model, same as my unit) was selling only up to 40,000 yen used, the bottom line of the Alpha 907 series.

there were a few Nikkos in Metro Manila back in the '80s but i think there's no amp surplus from Japan of that brand here in Davao or at Manila's pier nowadays. Nikko is a good brand though, especially the separates, but the only website you'd read about it is probably at AK's Vintage Audio. there are a lot of Hitachis among the junks arriving here, however, saw a couple of 5700s and even higher models (very heavy but mostly the silver editions) sold at prices less than those of the more popular brands here in davao these past two years. anyway, Hitachi's Japan domestic brand is Lo-D. there's a good chance you'll find a 5700 under the Lo-D brand at Manila's pier area or from the used hifi shops now.

uy, sabay pala tayo. i started also in early '80s and remember vividly those brands. visit the surplus shops and the pier outlets, you wouldn't believe the treasures you'll find there. i was in London in '89 and Jap domestic models back then that British audio enthusiasts could only drool at are sold here now as surplus amps at less that 5% of their original prices. even US audio enthusiasts think we're lucky to have access to those vintage high-end Jap equipment. many of those seriously into hifi believe that equipment made in '70s and '80s were generally superior, technically and sonically, compared with those built since the '90s.

I think I saw some HA amps sa Pier. Can't recall what models but these are not the ones listed in the Japan Nisi listings so i just passed em by. some are even power amps/controllers.. I saw some tuners but i understand that these are set to japanese stations and even if recalibrated, the analog indicators won't be correctly indicating the stations being monitored..

Ano ba sir and Japanese versions nung aud d11?

there are some points in your inquiry that were hardly covered in our previous posts:

- service centers usually don't accept Jap domestic gear but individual technicians do.
- if you know how to test and correctly set the DC offset and bias, there's little chance you'd have a problem wth your surplus amp. most of my surplus amps, at least half a dozen, were over 2 years with me now without trouble.
- use only 100-volt transformers to be sure; (110v transformers could harm your hard-to-find amp)
- consult JojoD for modifications, if he's not busy, he'll help you.

Post by: Lord Foo on Sep 20, 2005 at 07:52 PM
Clueless din ako but I followed the advice of Sir Sandawa and the other Guru's here....I read up on all their posts before buying my first unit at the pier.


100 volts vs. 110 volts.

I totally agree with Sir Sandawa re: 100 volts. My brod's Sony CD Player heated up faster when using 110 volt step down transformers. He had better results when using the flimsy looking 100 volt transformers u can buy at the pier for 200 pesos rather than the heavy black 110 volt transformers costing 500 pesos or more.


DC/BIAS ISSUE.

Also I've followed Sandawa's DC Bias offset advice on two of my units (a pioneer SX1080 and a Sony VFET 5650) and the results were extremely satisfying.  The sx1080 is now running cool as a cucumber after staying in the closet for almost a year due to extreme heat produced by the unit in the past.  The 50 watt SONY TA5650 is now one of my best sounding amps (IMHO). The thing is, u need the manual to calibrate for DC and Bias and some expert advice or you'll burn something in your amp real quick. I am now on a crusade to get Service Manuals on all my amps and check DC  and Bias settings.

Japanese household current is strictly 100Vac that is said to have little or no fluctuation.   It is important to have 100V step down transformer, preferrably regulated  types to ensure you get exactly 100V when loaded.  I think you can get better mileage out of surplus gears with this.   Never use 110Vac step down.
Title: Re: Surplus amps
Post by: sandawa on Sep 21, 2005 at 12:26 PM
true, although a Japanese trader here in Davao once told me their domestic appliances were made with a tolerance of plus or minus 30% of the voltage rating for a short period of time (a minute or so, he said), it's best to use 100 volts here since even the local transformers rated at 100volts go up to as high as 110 volts in residential areas. based on feedback, Jap made amps run okay for a while in the US (117 to 120V ac) but would eventually burn after an hour or more of use. so, if your Jap amp is plugged in a 110V transformer, you'll have a problem sooner or later.

the only difference i can see from your pic is that the Alpha907 used torroidal transformer while yours used an EI transformer. that being the case, you have to option to convert that to 220volts easily! there are many shops doing conversion to 220.

2ny,

i've been reading your posts and i assure you, even with over 20 years of hi-fi hobby (including some 5 years of trading hifi in Diliman in mid-80s) i'm learning a lot. it's true Japs had cut on expense for their international models to be competitive. even for same number models, those sold internationally were fitted with inferior, cheaper, components. thus, Jap domestic models, now known as surplus here, are of better quality. that's the reason why some Audio Karma veterans envy our stash of cheap Jap vintage gear.

anyway, here's the innard of the Alpha 907 for comparison with the 907X-Decade:

japanese have a different mindset when it comes to selling to their countrymen vis-a-vis selling to foreigners! they are very nationalistic you know. ;D

my japanese friend even told me that SONY is not that hot in japan!

i am able to judge quality of amps by looking at its schematics and innards! at least, those amps sold in saudi targeted for our OFW are of low quality imho. example are sansui's with grey plastic shells, i wouldn't touch them at all! but the sansui G-series are quite good also! so it realy depends on the model, some are lemons but there are GOLDS!
Title: Re: Surplus amps
Post by: sandawa on Oct 07, 2005 at 10:31 AM
true, those silver Sansuis sold here in the '80s were hardly distributed in Japan. matindi ang Hapon sir, Sansui's top of the line Alpha series in the int'l market is always one model down compared with their domestic models. Thus, the Alpha 907 series or its equivalent, was never sold internationally, only the Alpha 707 models - re-numbered 911, etc. - were sold in the US and Europe. the few Alpha 907 in the US (Jap domestic models as in our surplus amp) are now bidded at close to $2,000 used (even the Alpha 607, at over $1,000 used). that figure is 7 times the average eBay closed-deal price for the classic Dynaco ST70, which is quite popular here.

BTW, guys, if no one gets Wanderlust's 907x-Decade until next weekend's payday, akin na yan! but i'm giving a chance for others to own it since i already have 3 Sansui TOTLs. if ever, that would be my 4th and probably my 14th amp. hirap dito sa probinsya, walang shops to audition good equipment. thus, the only option is to buy the best ones and decide which ones to hook and which ones to shelve.

You may want to skip their models using their proprietary super feedforward circuitry which I heard was quite unstable at high volumes that easily fried the power transistors.  But I suppose those are the international models.  I don't know about similar sansui feedforward designs meant for the local jap market.  I think my old AU-D11 was also a feedforward design.  Though I don't recall sending it to the repair shop often coz I only listen at comfortable levels then.   ;D
Title: Re: Surplus amps
Post by: sandawa on Oct 07, 2005 at 10:57 AM
the feedforward technology was Sansui's comparative edge. it speeds up signal flow, which should result in faster musical response compared with other amps (notwithstanding the long winding connectors and electronics components the signal should pass through). 2ny or JojoD could probably explain how it's done, (something to do with bias?) but that technology was pushed to the edge in AU-X1, globally recognized as the "sunugin" amp, which Sansui engineers said was the best amp they produced ever (in late '70s).

i think Sansui used the technology for the silver series, as pointed out by AVphile, but it cautioned buyers not to hook the amps to speakers below 8 ohms. yang ang naging problema ng technicians sa V.V. Soliven dahil maraming speakers, especially US-made pairs bought from  expats' garage sale back then, that ran below 8 ohms average na kinabit sa Sansui silvers (kasama na ako dun - using ARs and JBLs).

anyway, since i have a file here for those technically inclined, below is the innard of AU-X11, which was the revised version of the AU-X1 para hindi na masunog:

it was a nice circuit trick whereby at high frequencies, feedback coming from the output stage (output transistors) were bypassed and feedback  taken from earlier stages, from the VAS(voltage amplifier stage, which btw provides for the full voltage swing of the output transistors) or predriver stages.

rationale behind this is that feedback coming from the output emitters are delayed so that it does no good at higher frequencies! at that time, there was an outcry against global feedback and this provided a nice workaround!

this is one innovation started by the japanese, technics i think it was who pioneered this. of course just as there are fads in clothing, there are also fads in the audio industry!

prof. w. m. leach thought it made a lot of sense so he incorporated it in his latest iteration the leach low tim ver. 4.5

feed-forward scheme was not responsible for this! output transistors getting fried in the case of sansuis, was a serious design flaw! being mass market, low cost amps, the designers designed the output stage on the assumption that these would not be overworked, meaning it will not be used at high levels and low impedances simultaneously for extended periods!

SOA(safe operating area) of the output transistors were overestimated! where 4pairs are needed, they put in only 2pairs, that is why the output trannies got fried! another reason is rails should have been lower but due to power specs race, they used the transistors near the edge of their ratings.

maybe they got freshmen engineers do the design! ;D

Sir Cire2005,

My humble advice po pala.

My experience in buying pier surplus units is that, the phono sections have problems. I have two Sansui AUD 707 that  both performed well with CDs but the phono output is horrible.  The problem in buying units for phono use at the player is that there are no test units at the pier. Maybe the gurus here can advise how to test the turntable section.

Foo.
Title: Re: Surplus amps
Post by: sandawa on Oct 08, 2005 at 09:07 PM
Sir Foo,

totoo yan ha! we should warn Pier buyers to be careful about that. this is also true here in Davao. i have three Sansuis, yung isa (AU-XII - TOTL in early '80s) may problema ang phono section. kung minsan pag uminit nawawala ang signal. also, i have three upscale solid state preamps, all surplus, one has a noisy phono section. i remember Diego also complained about this to me and the shop he bought the unit from does not even have a turntable or LP record to test his amp's phono output.

mukhang one common problem for upscale units from Jap recycling centers is the phono section. siguro galing yan sa mga audiophile/vinyl addicts and instead of repairing those units there (minimum service charge - outside of parts - for a minor problem is 5,000 yen, or a little less than $50) binebenta na lang nila ng por kilo sa recyclers.

kung hindi vinyl inclined ang makakabili, no problem. pero Pinoy analog addicts would be disappointed. the best way for those going to analog who intend to buy at the Pier is to test those amps - puwedeng improvised, hook an RCA connector sa phono jacks and hold the ends, dapat may hum or low frequency sound feedback yung dalawang channels - at pareho ang strength ng volume. the best, however, is to bring a turntable, tulad nung old burger-type portable TT ng Audio Technica.

this is because the phono stage has its own preamp inside the amp and due to dissuse for a very long time, the contacts on the selector switch would have been tarnished, cleaning with wd40 may help. besides the eletros in the phono preamps may need to be replaced. you can order replacement caps from farnell or rs, panasonic low esr's are a good choice, bypassing with polypropylene caps can do wonders!

it's your call. contact cleaners could be either freon based, or tce based, wd40 is oil based, so when using this material be sure to wipe off any excess as it can attract dusts. isoprophyl alcohol can also be used. i have also tried lighter fluids with good results. as always clean off any excess!

but ultimately, the best thing to do is to replace that switch if replacement could be found!

2. cleans circuit boards
3. instant penetration (not for humans) ;-)
4. windstands high temp
5. removes stubborn stains
6. lubricates & cleans carbons (for guns)
7. cleans & lubricates fans
8. lubrication of door hinges
9. acts as a coolant (?)
10. cleans & polishes stainless steel
11. cleans battery contacts

14. cleans contact point
15. can be used for marine boats & motor vehicles (?)

my thoughts exatly... though I use a dose of WD40 first, then a healthy dose of Elektra (I always remember Jennifer Garner when I say Elektra  ;D). does wonders to contacts indeed.

Agree w/ Bruno. Never use WD-40 in switches because it's basically an insulator and will increase line resistance. The best contact cleaner to use is Philips. It cleans the contacts and then lubricates them to reduce  wear and tear. That's why it's the only one they use in Sony sevice centers.

I saw two top of the line units at the pier in the past three weeks:

A Sansui AUD907Fextra and a Trio (kenwood) ka9900.  I didnt have the money to get them though.  Later I returned with the money. As expected both units were gone to some lucky audiophiles.


I decided to finally buy two units i have been eyeing before at the Pier surplus area for the same amount I earmarked for either of the two TOTLs.

I brought home a Yamaha CA1000 and a sony VFET4650.
The Yammie was a TOTL also when it was released while the VFET is a rare unit buyers should be wary of. The VFET parts when damaged can not be replaced and the units become junkyard metal.

Hello bro gutchy,

Wow! Ganda siguro ng tunog niyang au-907f. 8)  

BTW, hindi yata VFET yung 3650 (according to Axel ng AK).

Kya nga ako rin mag-aabang ng AU-907.. inggit ako dun sa friend ko.. end of october pa raw ung next shiftment nila.. hunting ulit!!!

buti pa kayo dyan may magagandang dumadating. that's the correct pricing for those amps, from P10 to P15 per watt (based on power consumption at the back). yan ang dating presyo dito sa Davao nung marami pa rito, ngayon mahal na yung magaganda - at wala nang malalaki na dumadating.

true, the Sony 3650 is not part of the much sought after VFET batch. yang si Axel (Paris-based) bilib na bilib sa Pinoy kasi daw bakit ang daming audio collectors' items dito sa atin. nagkwento ako sa kanya na sikat na sikat sa Philippine hifi boards ang site niya: http://www.thevintageknob.org/ hindi niya alam puro Jap surplus yung mga units natin. mahal sa kanila yan, yung iba sa Audio Karma naghahanap ng lumang VFET willing to pay up to $500 each for the TA-4650. the Marantz PM-84 is good buy for P5.5K, baka puwede pang tawaran: http://www.quarter-a.netfirms.com/pm-84.htm

Sir  Sandawa,

I sent AXEL a longish explanation of the Surplus amp scenario in the Philippines as far as I know.  He asked what I meant by "surplus" in an email to me about the VFET TA4650 that i registered in his Vintage Knob site. So he is now aware of the surplus scenario.

Sir Gutchy,

Haha. So it was your friend who got the TOTL AUD907Fextra.  I hope he's also a member of this forum.  He's much quicker than I am. Give him our congratulations on a nice amp for a very good price. 

The TA3650 is indeed not a VFET. Its the TA4650, TA5650, and TA8650. Please don't pay much money for these units at the pier. Tell the sales guys that its very risky to buy these units because the VFET parts are not replaceable and their liable to get damaged. heheh. Let's not push up the prices.

I haven't hooked up the CA1000 yet until I've had the alignments and adjustments done. However, Sir Sandawa has a Yamaha CA1000iii which is very similar and he's mighty fond of his unit - and so are the Audio Karma guys.



Sir Cire,

So you haven't sourced an amp with a good phono yet? Let's ask Sir RNS to test  his TA5650's phono stage. I know he has one with him. Maybe the VFET also matches well with Turntables. I have heard the VFET with Sony CDPes players and they are absolutely, stupendously nice.  :D. (my humble opinon po!)

Title: Re: Surplus amps
Post by: rustyns on Oct 21, 2005 at 11:54 PM
Sir Lordfoo,

I agree that in my very limited vintage audio experience, I have not heard a sweeter sounding vintage ss amp than the sony ta5650 when used with a cdp (sony cdp333esd). -except for maybe the Marantz Esotec PM6 - wasn't able to compare side-by-side

I have tried using an entry level Marantz turntable with some vintage amps. This is the list of amps I listened to. It is arranged according to how nice it sounds (IMHO)
1. Sansui 5000x (very nice)
2. Pioneer sa9500 (ok)
3. Sony TA5650 (weak and noisy)

Here are some theories I have on why the TA5650 is at the bottom.
-Its phono stage is really bad as discussed by some guys in AK
-Both the 5000x and sa9500 have been thoroughly cleaned then recapped(replaced electrolytic caps)
-just a "matching" issue

As usual, these are just my thoughts and opinions. I guess you have to try it yourself and let your ears decide.  ;D
Title: Re: Surplus amps
Post by: sandawa on Oct 22, 2005 at 10:47 AM
AK members are having a ball. there are two VFETs - Sony TA4650 and Sony TA5650 - on US eBay, the seller seems unaware of his units' demand and is starting at very low floor price. my suspicion is that the seller is also from AK testing the waters, so to speak.

When I visited the pier last June, there were stacks of tuners in one stall, most were flagship models during their time.    The sales guy said there were not yet rechanneled, but they'd gladly rechannel the tuner of your choice at no additional cost.

The second generation of the 07 Series.  Introduced the "Diamond Differential DC (DD/DC) Circuit".  As the results, improved the total harmonic distortion to 0.008% from that of 0.03% on AU-707.  The international version, AU-919 was equivalent to top of the line product, AU-D907.  Frequency response DC ~ 500KHz, 100W + 100W into 8 Ohms within 0.008% (10Hz ~ 20KHz).  AU-D907 was sold at about $550.00.

-Best of Sansui (http://www.sansui.us/PG_AUD907.htm)

0.008% THD :o Super-FI na ito.

When you read the specs of those fine amps made in the 80s, you'd be amazed that most of  their frequency responses were often from DC to 100khz with a THD of 0.005% at rated power (Both channels driven) at full bandwidth.

These days, those flaghsip HT receivers bannering their WRAT abilities are only doing 10hz up to 30khz with a THD of around 0.05%.  That's 10 times the THDs of those amps made in the 80s.  And just a third of the bandwidth.  

It seems amps of the 80s had finer fidelity qualities.   ;D

aside from those mentioned above, the original AUD-907 i saw a year ago had separate/coupled switch for power amp and preamp sections at the back. that feature is no longer offered in succeeding 907 models except for the Alphas (could acommodate two external preamps). at P2.8K that 907 is a steal. however, check if it was already repaired, specifically if components were already replaced. meron kasing ibang shop, pinapalitan ang laman tapos mapatunog lang ibebenta na.

Sabi sa akin ng kaibigan ko kailangan mo raw kaibiganin ang mga kargador at magbigay ng padulas dahil by the volume ang bilihan. Pagdating kasi nung container isa isang binabasa iyung mga nag pa reserve. Pag tawag sa pangalan mo kailangan kunin mo na ang allotment mo at hindi ka na puwedeng magreklamo.

Sabi nung kaibigan ko pwede rin pa isa isa kaya lang mas mahal. Medyo nakakatakot dahil kung wala kang alam sa electronics at ang nabili mo ay ayaw tumugtog yari ka na. Maganda siguro magkaroon tayo ng group buy at tulong tulong na lang tayo na ayusin iyung mga ayaw gumana. Anong say niyo?

Rascal,

Hi. Mukhang ganyan din ang approach sa mga surplus right hand drive vehicles and also ung audio surplus sa pier.
Delikado nga pala ung kalakalan diyan. Kasi even sa pier na may 3 to 6 months warranty na nga at nabubuksan at na te test mo yung units, delikado pa ring bumili. Try returning a unit that you've bought already.

Pero interesado ako sir rascal. I've always wanted to see how the surplus audio equipment system works.

Title: Re: Surplus amps
Post by: sandawa on Oct 24, 2005 at 07:51 PM
that is the correct move. i actually suggested that to the previous batch two years ago. this is because i observed here in Davao that ex-warehouse prices are quite low compared with pricing at traders' shops at the Pier in Manila (or even traders' shops here). if you can go direct to suppliers as a group, amp pricing is only P10 per watt (power consumption at the back as basis), while CDP, TT, and tape deck (upscale or mid-model) is only P500 each. VHS and Betamax machines are sold only at P100 while TV, 14 inches at P300 to P500, bigger screen TVs as low as P1,000 (i got a good-condition Hitachi 28-inch widescreen TV at only P1.8K)

the scheme here in Davao is you deposit a certain amount and they call you when a container van would be opened. then you can choose from the equipment being unloaded. in effect, your group will be competing against the other traders who operate surplus shops. if there are more than one trader (including your group) interested in the unit, the auction system applies. thus, the higher bidder gets the equipment. the total amount of the equipment the group chooses is deducted from the group's deposit, which needs to be replenished regularly.

i'm not a trader, so i only get to buy from warehouses here units the traders did not choose. if i like a unit that went to the trader, i would usually chase him and offer a premium price higher than his acquisition cost. in my experience, 7 out of 10 "as-is" units from warehouses are in good working condition, or could be repaired at home - i.e., replacement of belts or fuses - while the rest needs a technician and almost always could be repaired within a day.

Cez's General Merchandise at #477 MacArthur Highway, Dalandanan, Valenzuela City. If you are looking directly at PureGold Valenzuela it is at your right. About 10m away from PureGold compound.

Iyung warehouse nila - Sylvia's General Merchandise (where the Sansui is),

   Northbound, MacArthur Highway, about 1 km away from Cez's, to your left, if you reach Banco de Oro nalagpasan mo na siya. It is
   about 50m from Banco de Oro kasi

Asked about container arrival schedules. They said that for security reasons they are not at liberty to tell. Will just call me when shipment of amplifiers arrive. Also said to be prepared have at least Php 30,000 or worst case about Php 100,000. Iba iba kasi presyo.

Kung pa isa isa ... prices ... it based on the input power ... only remember 150W to 199W about Php 2800 (pero puwedeng kang tumawad).

hi guys, it's been a while since i posted here, it's been 2 years since my friend karipas asked me to accompany him to the pier (and thus the thread was born).

last weekend we went there looking for a CDP and instead we almost went home with another Sansui amp.... it's a vintage mid-70's model AU-7700 that looked good externally.... if only for its display potential and the asking price of P2,800 (guy in store said "pwede pa bumaba") my friend said it seems like a worthy acquisition if we can get it for P2,500.

i checked the net --- it's a budget model, 54W x 2, the 0.1% THD is unusually high, and the eBay price is relatively low at $52..... the real keeper would have been the higher model 9900.... still, it looked good enough for P2,500..... i really wouldn't consider it at anything higher, since our previous Sansui blows it away at every criteria.

then i came back and asked the guy -- what's your last price?  ......he says P3,200.

ano?? sabi mo "2.8k pwede pa bumaba" tapos ang last price 3.2k??  he ought to wipe the drool on his chin coz he's probably thinking he got me there..... if a buyer comes back the next day looking for a specific model he probably wants it badly..... enough to bend over backwards and get screwed.... anyway, he denies having quoted us the price i was expecting, and soon he was looking at my back and i'm riding into the sunset. :P

the guys at Chatty's tend to overprice their gear when they see you're interested in a particular gear, they once quoted me 4k for a Marantz CDP...... ika nga ng boss ko pag nakaisa sa negosyo, "I'm not as stupid as i look".  :-X

at 120 watts power consumption, AU-7700 should be priced at only P2,400 by traders here in Davao and no more than P1,500 from the warehouse. however, collectors in the US would likely pay more. the Orion Audio bluebook (used as reference for insurance by US forwarders) says its average closed auction deal was at $84.

i used to be a lurker here three years ago, until i realized we also have recycled Jap hifi here in Davao and at lower prices. thanks to Sir Akyat and the first batch of posters here - iceman, avphile, audioslave, wanderlust, etc. - i have refrained from buying any expensive new audio equipment and now maintains a sizable collection of selected Jap recycled gear.

sayang i sold the precious one due to financial need last year, i also would have wanted to build a collection of gears with significant historical & sonic value..... sort of like niji's list live.

when i look at my current roster of amps and think about how much they cost me..... whew! life was much simpler back then.... due to my near fiasco last year i have in mind a super downsized, minimal cost setup that includes a Wharf 9.1 speaker, Sansui amp and Sansui tuner -- that's pretty much all i need, with unlimited source material coming from the tuner.

but i'm hoping i dont have to downsize, coz there's still too much to explore.... in this hobby, the journey is as much fun as the destination.

the same goes for us diy'ers, 90% of the fun is in the building of audio gears! 10% in listening only in my case!

to be able to build something that you can call your "own flesh and blood" is something that is very hard to equate to pesos and cents! ;D

@sandawa,

i was thinking of taking this philtranco bus from pasay to davao, are you accessible via that route? ;D
Title: Re: Surplus amps
Post by: sandawa on Nov 01, 2005 at 01:57 PM
yes, that's a good route for someone into DIY -- my favorite adventure route in fact. it would take you 44 hours from Manila to Davao but along the way are the zigzags in Quezon and Camarines Norte, Mt. Mayon in Albay, the beaches in Sorsogon, the rustic rural scene in Samar and Leyte plus San juanico Bridge, Surigao's greenery including a view of Lake Mainit, the heart of beautiful Agusan and finally the Davao Region - from the golds of Monkayo to the banana farms of the Floirendos. bring a camera with extra memory cards.

if you're thinking of sourcing surplus hifi here, however, forget it, you'll be disappointed. we don't have a lot of arrivals lately. you have a lot more in Pier or in Valenzuela (as posted earlier). if you just want to enjoy southern Philippines and get a glimpse of Davao's hifi, and take a chance at what's available, that would be wonderful. i promise you, hindi ka magugutom dito sir, tataba ka pag-uwi mo sa Maynila!

Post by: mandrake on Nov 02, 2005 at 10:03 AM
Speaking as a first time owner of a surplus amp, I must say ang laking bagay talaga ng forum na 'to.  I started reading this last year and gradually realized surplus equipment was a viable path to having a dedicated audio setup.  My biggest problem was allocating time and getting my wife to accept such a decision.  Para sa kanya kasi I was willing to pay good money for junk :P

What finally made me take the plunge was reading Sandawa's very informative posts.  With perfect timing, one of the more sought after models suddenly became available; Wanderlust's Sansui AU-907X Decade.  Here was an amp that had provided good service to one of the more active members here and who, coincidentally, I  also met during last year's grand EB.  Plus it had the pedigree, eka nga.  Paano ko palalampasin 'to?  So I didn't ;D  I chose an alternative path to surplus audio heaven ;D

Just this weekend I found a slight problem with the amp and after asking Wanderlust, we agreed that  Sandawa would be the best person to go to.  As expected, he was very helpful and I finally got the problem fixed ;D  Master Sandawa you're really the man!

Ang haba na ng kwento ko but what I'm trying to say is basically the same as what Akyatbundok said: the journey is as much fun as the destination, no matter what path you choose to take.

even though i liked the unit, i didnt give in to this unfair business practice and decided to just let it go and hoped that the seller somehow gets the message

Title: Re: Surplus amps
Post by: sandawa on Nov 02, 2005 at 04:05 PM
VFET (vertical field effect transistor)-driven vintage amps are now the object of a hunt among audio enthusiasts worldwide. VFETs were built by a few Japanese hifi firms back in the '70s to mimic the sound of valve/tube amps. unfortunately, due to high cost of production, VFETs were discontinued. there were very few amps that used VFETs. ang problema, nakakuha ka nga, nasira naman, wala rin - no more parts available.

Title: Re: Surplus amps
Post by: sandawa on Nov 02, 2005 at 07:10 PM
true, pero kung tested na maayos ang VFET amp - habulin! Lordfoo and another guy here, i think, got a Sony TA4650 and TA5650 respectively, at very reasonable prices. iba talaga ang tunog niya, lalo na sa mid-range. it was produced to sound like a triode, thus the tube-like sonic character. hindi kasing linis ng high-power mos-FETs (which i personally prefer) lalo na sa gitna, but it has a distinct sound, that is, if you want some variation.

i have a Yamaha B3 VFET power amp (the only Yamaha B3 in Audio Karma). gulat ang mga taga labas sa Pinoy, paano tayo nagakaroon ng collectors' VFETs. di nila alam sa junkyard ko napulot yung unit ko. it's now packaged with a WS Tono tube preamp, on a biamp mode with Sonic Impact tripath amp, and driving KEF 101 series 2 speakers. the Yamaha VFET handles the mid and low frequencies and the T-amp takes care of the high frequencies.

here's a photo of the Yamaha B3 beside a WS Tono (with T-amp on top). below is the bi-ampable KEF 101 series 2 which i modified early this year cutting the HF unit at the woofer's center and mounting one on top:

@sandawa,

way i understand it, v-fets are bised quite high, at more than 250ma at idle, higher order odd harmonics tend to be minimized at the output stage, thus the tube like sound!
Title: Re: Surplus amps
Post by: Lord Foo on Nov 02, 2005 at 08:01 PM
The sony TA5650 and TA4650 are really very nice integrated amps.  The TA5650 with me used to behave like an egg fryer but when my brod adjusted the DC Offset and Bias based on the service manual provided by Axel of Audio Karma, the execessive heat generation went away.

The unit still heats up but its not very hot anymore and the sound it produces compares very very well with most of my amps. The unit is now being used by Rusty. I havent found a service manual for the TA4650 so I haven't used it up yet. But the two times,  I powered it up, it sounded more suited to my taste than the Yamaha CA1000 when every setting is set to neutral.  The bass is simply superb.

Let me describe the base with some poetic license...

Awesome bass emanates from the woofer, crawls on the ground, climbs up your toes and up your legs. It makes your knees wobble. It socks your stomach, squeezes your heart and slither up your face. The bass brings tears to your eyes and finally, it oozes slowly and gracefully out of each single strand of your hairtips - making them stand up as if in fright but in reality is in audio ecstasy.

do you know at what level in mA, is the bias set now? and what it was before the adjustment.? did you try to measure the bias again after a few hours of playing just to make sure the bias compensation is really up to its task?

higher heat distinguishes bipolar amps from vfets or mosfets amps. higher bias for bipolar outputs also tend to minimise higher odd order harmonics but bipolars are much susceptible to thermal run-aways thus prohibiting higher bias.

Sir wanderlust,

(http://i34.photobucket.com/albums/d106/mykatjak/Audio%20gears/AU-D907Xpots.jpg)

Post ko na lang dito ung ginawa ko (hope di masyado OT).  The two blue pots sa bandang kanan na encircled in yellow (malinaw ba?) ang ginalaw ko para ma-adjust ang DC offset.  The upper one is for the left channel and the lower one is for the right.  Hinulaan ko lang kasi may nabasa ako na label katabi nila that says DC1 (or DCI.. di na ganun kalinaw mata ko :P).  Plus they're quite near the clearly labeled pots for adjusting bias (the four to the left of the offset pots).  I figured the designer would have put these adjustments near each other and easily accessible.

The procedure for measuring DC offset I got off Echo Wars post in Audio Karma; di ko nga lang nabasa lahat so I wasn't sure about the actual procedure for adjusting it.  Sandawa gave me the idea of fixing the probes of the multimeter onto the speaker terminals while adjusting para mabasa kaagad ang reading.  You have to adjust in very, very small increments.  Halos di ko nga makita ung galaw ko sa pots...pinapakiramdaman ko lng :).  Then you wait for the voltage to stabilize...something like 10-20 minutes.  Anyway, last time I measured nasa -11mV ang left and 8mV ang right.  Before I was getting 200+mV sa right.  Ok sana ung initial measurement ko sa left kaya lang yun ang una kong nagalaw kaya I had to work on both na :-\

BTW, the two pots on the extreme right of the pic near the right side panel of the amp are labeled DC0.  I didn't touch those since there's normally a metal plate that covers them.  Following the logic that the offset adjustments should be readily accessible, I thought it better not to fool around with them.  Hindi nga pala sa akin ang pic; it's from this site http://amp8.com/index.htm .  If I had seen this first I would have known which pot not to touch :P

Oh, and buy yourself one of those plastic adjusting tools if you plan to do this.  Baka sa Radioshack meron.  They're like plastic screwdrivers, I think.  Me I used a normal metal screwdriver.  Not recommended because of the risk of dropping it inside your amp while power is on.  Common sense, I know.  But you know what they say about common sense... ;D  Nauna lang ang lakas ng loob at tibay ng sikmura ko kaya nagawa ko 'to.  Besides it was a long weekend and I had nothing better to do  ;D

jojo,

notice that aside from the 4 pots, there are 4 coils and 4 sets of zobel networks to the left! they are for 4 amps! two amps bridged to make a stero amp!

speaker system A and B are selected thru relays! measure the voltage at the black terminals on either A or B, whichever is selected,and the chassis case and you will find that it is not zero! output offset in this case means that the voltage across the black and the red terminals must be zero!

(http://i34.photobucket.com/albums/d106/mykatjak/Audio%20gears/audio005.jpg)

Ano advantage ng four discrete amps for stereo?  Improved sonic qualities?  Di ba parang mas marami pang pwede masira ???   And what are those two pots on the extreme right side of the amps for?  Nabasa ko kasi ang label parang DC0 or DCO.  Do you think these have anything to do with DC offset adjustments?  I still hear a slight sound coming from the right speaker when I turn on/off the amp.  Dati before I adjusted the offset mas malakas ang tunog.  Ngayon you really have to listen for it para madining mo.  But it's there and I would like to get rid of it.  Kasi it means something is still not quite right, di ba?  O baka naman may ibang problema pa ???

1. you get the same power output for half the voltage rail.
2. slew rate is doubled.
3. output signal is isolated from fround.
4. output transistors get to enjoy bigger SOA, thus is more likely to survive overloads better!

anyway, jim bongiorno of the GAS ampzilla fame also came out with this topology in his SUMO line of power amps. the japs are easy to catch up!

speaking of SOA, any amp that has a SOA that can withstand the full rail voltage is very hard to get destroyed in use!

What I meant is the amp has 4 separate channels inside. 1 pair for speaker A and another for speaker B. It is not bridged in any way, it is single ended. That's what I noticed when I open her up.

Title: Re: Surplus amps
Post by: JojoD818 on Nov 05, 2005 at 02:54 PM
skylark,

most hi end design amps offer 2 trimmers for dc offset setting and bias setting. though some only has 1 trimmer that sets the bias current.

to make it short...

dc offset = sets the output DC voltage of the amp to 0V, though this may sometimes be unrealistic, a max of 0.1V dc offset is globally accepted. anything higher can damage your speakers especially the tweeters.

bias current adjustments = sets the optimum idle bias current for the opt transistors.

so if your amp has high temps even when not playing music then there is probably something wrong in the bias circuit. or even a simple trimmer failure can set your amp's bias to the max. well, at least you're amp is biased in class A now.  ;D Just joking.  :)

I'm sure 2ny has more "in-depth" text descriptions from his library of books and magazines.

I'm confused. Do these assumptions assume that the amp is bridged?


don't be, the amp is bridged to make it a stereo amp! it is not unussual that it is so... ;D

It is not bridged in any way, it is single ended.

single ended? since when? ;D you must be mixed up with tubes! ;D ;D ;D

sir meron po ako na yamaha surplus reciever 110 pwede po ba rin e off set DC nya ano po ba advantage pag na off set sya kc ang bilis nya maginit kaya di ko na sya ginagamit sa ngayon and paano sya e off set

ty po :-)

can you post pictures? it easier if we have something to look at!

dc input offset and output heating up are two separate isssues!

dc input offset has a lot to do with matching of the input ltp, heating has to do with biasing the output transisors.

dc input offsets displaces your speaker cones from dead center! as jojo said, 100mV is acceptable, but 0v is ideal!

biasing the output stage more results in more heating.

2ny/jojoD,

your exchange is truly informative. it forces you to share with us things we should learn in this hobby. i hope i could have an appointment with you guys and let's have coffee together during my regular one-week Manila visit in January.

sa inyo ko lang nababasa ulit yung mga hifi heroes ko nung '80s such as Bob Carver (Phase Linear, Carver, Sunfire) and Jim Bongiorno (SAE, Great American Sound, Dynaco, SSTI, etc.). i'm adding a few more names responsible for those vintage amp gems: David Hafler (Dynaco, Hafler); Dan D'Agostino (Krell); Nelson Pass (Threshold, Pass Labs); Tomlinson Holman (Apt Holman, THX); Tim de Paravicini (Luxman, Musical Fidelity, EAR); Gordon Gow (McIntosh); Saul Marantz; Mark Levinson; etc. (plus Jap hifi heroes such as Sony's Akio Morita and Sansui's Khosaku Kikuchi).

the Bascom King article in Audio magazine about VFETs, i think, is the only comprehensive paper on the subject published in the US. unfortunately, Japanese engineers discontinued production of VFET amps before the technology could be applied by US and European audio firms. no wonder, today's VFET collectors are mostly from the US and Europe. the majority of those amps, some still in good condition, were made in the '70s for the Japanese market (some from Jap recycling centers are shipped here such as Sony TA4650, 5650, etc.)

@sandawa,

i am working my way back to russia hopefully by december!

about personalities, there is of course david hafler, of tube and ss fame, daniel meyer, for his "tigers" that was basis for my first diy amps. then there is this proffessor from Georgia Tech, William Marshall Leach, he never made any commercial amps, but his lo-tim, and doubble barrelled amps, are now considered legends in the DIY worls, leach amps became the basis of many succesful commercial amps! Leach together with Matti Otala of finland, quantified and described the TIM phenomena and wasy to overcome them. then there is Nelson Pass, his Stasis Amps were licensed to the japanese. let us not forget also John Curl, Mark Levinson, Walter Jung and many others!

there is a lot to learn about amplifiers, we barely scratched the surface!

i am hoping that with this we can pass on to the next generation the wealth of knowledge that we have accumulated thru the years!

i figure if i am able to inspire several young men out there, then i would have served a purpose!

it will be a pleasure to have coffe with you anytime!

pambihira ang labo, tagalugin na lang natin para malinaw.

naguguluhan ako sa sinabi mo kasi hindi naman ito applicable dun sa amp na yun dahil hindi nga sya naka bridge. yun speaker A & B ay may tig-isang amp. ang nililinaw ko lang yun sinasabi mo na SOA pero ok na yun kasi binaba mo pala yun supply voltage ng kalahati.

ang ibig ko sabihin single ended ay isa lang ang hot sa output kasi yun negative nasa ground samantalang yun bridge ay parehong hot at walang reference sa ground. hindi yun output topology ang sinasabi ko single eneded, yun connection lang.

may sipon ako pero wala akong lagnat.  :)

@jojo,

i think my posts are clear!

i understand now what you mean by single-ended, ;D i believe "unbalanced" is the correct term! when one end of the load is ground refferenced(connected) and the other end tied to a hot side!

that amp is a "balanced" or bridged type output, that is why there are 4 discrete output stages! :D

the 4 discrete amps are in turn push-pull. ;D

let us not mix up terms, lest we confuse the newbies!
Title: Re: Surplus amps
Post by: JojoD818 on Nov 06, 2005 at 10:17 AM
I agree with the clearness, it's just that you're assumptions has declared new parameters.

Anyway, I disagree because the amp has 4 outputs (unbalanced if you will). 4 speakers can be connected, that is 1 pair for speaker A and 1 pair for speaker B. At least that's what it says the last time when I opened her up.

Regarding the mix up, it's true only peanuts should be mixed up.  :D

it may interest you to note that i also had the chance to open up that amp, but unlike you, i replaced all four sets of speaker jacks! pangit kasi yung 2 bago then yung 2 luma! ;D

that is how i came to know that this sansui amp has a bridged type output stage!

i am not basing my comments on mere pictures alone, but on actual investagitation of the circuit board itself, as it took me longer to adjust the off-sets! and i found out thru inspection that indeed that was a bridged type output stage amp. ;D
Title: Re: Surplus amps
Post by: JojoD818 on Nov 07, 2005 at 01:36 PM
it's a user request to replace only the first set of speaker connectors. i remember because only the speaker A was useable after a repair by someone was done to the amp, the speaker B has all sorts of problems and the owner says to leave it out because the former repair only made it worse.

as for the bridge topology, if it is true that it is in bridge then there should be 8 discrete amps inside, 4 to form speakers A and another 4 to form speakers B. Is this what you're saying?

sir 2ny,

Thanks for the reply to my PM.

My amp is Onkyo Integra A-701 when my mother used this last saturday, she didnt notice na nka-full ung volume kya pag-play ng cd ..ka-boom

when i checked it busted na ung fuse and nung pinalitan ko burn-out again.. when i check the power transistor shorted na.. also the biasing transistor.

as you said, i need to check all the components from input to output.. to be sure na wala ng iba png nasira or else si2rain lng ulit ung opt ko.. oo nga sir thanks for this tip.

sir any procedure on how can i properly bias the transistor? there are only 2 trimpot on the amp section one per channel..

what other things to check before placing the new transistor?

pacensya na sir this is my first time to repair an amp..

i'll try to post the pics tom..

salamat ulit

whenever the output transistor fails, they take other parts too, like drivers and bias transistors and diodes, you should find  them all out .

when powering up, you can series connect a 220volt 50watt incandescent lamp in series with the ac line, this can help prevent loss of your output transistors in case you missed out something!

biasing the output stage, you can measure the drop accross the remmiter resistors of the output transistor, a reading of 11mV will correspond to about 50mA bias.

i have been to a surplus shop in my place here in the province. below are the items i am interested but wanted to ask some opinions:

Amp:
1. Yamaha AX-500 : 6k pesos
2. Victor AX-S700 : 6k

CD Player:
1. Yamaha CDX600 : 2.5k pesos
2. Denon DCD-850 : 2k pesos

Speakers:
1. Pioneer Private S792V : 3.5k (3 way, 8" woofer)
2. Sansui SCH07 : 2k (3 way, 5 1/2" woofer)

does the above items considered hi-end? alin kaya dito ang magandang amp/cd match or kung okay ang speaker isama na rin sa matching. di ko nakita itong mga model sa niji website.

Experience ko lang sa Pier this Saturday ...

May nakita akong amplifier sa IMJR na Yamaha CA-2000. Wow ang ganda sabi ko sa sarili ko. Hindi ko alam mayroon na pa lang interesado at nakausap na iyung lalaking ka may-ari na katabi ko. Kaya lang hindi pa siya sigurado.

Anyway, pinakuha ko tapos pinatugtog ko at nagustuhan ko. Sabi ko sa babaeng may-ari na gusto ko ipa-reserve at bibilhin ko this (coming) Monday. Binigyan ko ng Php 500 iyung babaeng may-ari. Pagkatapos ng ilang minutong pakikipag-usap sa kanya biglang nakisawsaw iyung isang lalaki at sabi pina-reserve na raw niya iyung amplifier. Galit na galit at nag-kausap na raw sila nung lalaking ka may-ari. Pinatawag niya iyung lalaking ka may-ari at iyung nga sinabi niya na may usapan na sila. Sabi sa aking nung lalaking ka may-ari pasensya na lang daw.

Kainis talaga! Kung hindi ko pina audition iyung amplifier at hindi ako nagpakita ng interes hindi siguro magkakagusto iyung lalaking iyun. Sayang ... ganda pa naman tumunog ...

that's a bargain. if i'm not mistaken, someone from this thread saw an A-917F last year at the Pier but the price quoted was P6K(?). at 80wpc rating, that would be about 200 watts (or a little less) power consumption, which means the Pier traders are now using the P20 per watt guide, the factor used by Davao traders (either binabasa nila tayo or they consulted with Davao importers/traders). BTW, the Japan auction price as per mentioned URL was 25,000 yen, which is roughly $200.

you hit it right, sir. part of the thrill in surplus hifi collecting is haggling with traders who, sometimes, are not familiar with their commodities. i think the next step is for them is to bring down the price of other components such as vintage CDPs - P1,000 to P1,500 per unit from traders here in Davao, so the comparable range there in Manila (kasi mas mataas ang per capita income ninyo dyan) would be from P1,500 to P2,000.

you sure got a bargain for the a-917 . a friend on mine got his for 5k (black though) last month. this is rated at 80 watts 8ohms / 100watts at 6ohms. I have the champagne colored big brother of that the A-919 rated at 120 watts. I have the japanese manual of this , if you are interested . The specs are can be deciphered but the rest of the manual can't unless you can read japanese. I dont know how to attach file thru this forum but i can e mail you if interested. send me PM  of your e mail add. The 919 was my first surplus amp bought 6,500 here in davao 2 years ago and have not regreted purchase. Main difference i think between the 917 and 919 is that the 919 has two transformers to run the left and right channnels. This accounts for the weight difference between the two units.

ayaw magpa tawad ang seller, so i didn't buy the M-506. after a few days, i visited the shop again to check the unit but a pastor/priest from Cotabato beat me to it. mahirap maghanap ng M-510, i just checked with Japan's auction records, and it's still selling used at over $1,500 each, three times the average auction price of Alpha 907.

I tend to agree.  But the comparison is not really fair.  The 907 is an integrated.  The Integra M series are power amps that are often paired with the P series of preamps.  The M and P series are definitely in a class of their own.

the onkyo integra M510 imho is miles away from the alpha 907. ;D

i also believe M-510 is superior than the original Alpha 907, but IMHO the big difference in current used pricing is a combination of model age and power ability (late '80s, early '90s vs. mid '80s for Alpha 907 / 300wpc vs 160wpc). but M-510's price for instance is at par with its contemporary, the lower-powered (160wpc) Alpha 907NRA. Sansui's TOTL in '90s, the Au-07 anniversary (only 90wpc) however, has current auction price average running twice that of M-510. it was never sold outside Japan.

here's a trivia, a US publication once noted there's a difference in the innards of the Jap domestic M-510 and the M-510 used in the international market. that's the reason why the export model was sold outside Japan at par with the domestic model or roughly $4,500. ordinarily, US price of original Jap equipment is retailed 50% higher in the US to cover for the freight and dealers' margins.

mas maganda talaga ang M-510, sir and at 63 kgs. pa, that would translate to awesome clean power. i stand corrected on the date of production - also mid '80s, but the price is correct. the yen to dollar conversion in 1984 was roughly 200 to 1, so about $4,500, same as retail price listed in Stereo Review 1989 directory.

Spec units are rare and are sought after:

http://www.silverpioneer.netfirms.com/power_amps.htm
http://www.silverpioneer.netfirms.com/pre-amps.htm

(http://www.classic-audio.com/pioneer/pics/spec2.jpg)

"Pioneer did not traditionally build separate power amps, choosing instead to build a great line of integrated amps.  But when Pioneer did build power amps, they were among the best in the world.  There were four amps of note: the very rare M-22 and M-25, and the long-lived SPEC-2 and SPEC-4"
(http://www.classic-audio.com/pioneer/pics/spec1.jpg)
I saw 2 spec units kay Art Flores when I went to his place several months ago.

Sa buy and sell, here are some advertisments that I saw and pasted into an excell sheet. This should give u an idea of the asking price for these power amps in the local market.


12/24/2004   PIONEER AMP. 15,000 (neg) spec-4, USA. Val 362-3605 or (0919) 8084553.
11/9/2004   PIONEER PRE-AMP. 12,000 SPEC-1, US made. (0919) 8084553.

6/22/2004   PIONEER STEREO AMP. 8,000 Spec-4. Val (0919) 8084553.

Check out also the Pioneer elite amps, I don't know if some of these models ever find their way into the Surplus market.

http://www.elitestereo.netfirms.com/amplifiers.htm

I saw a local ad for a Pioneer A77x once:

8/10/2004   PIONEER AMP. 18,000 A-77X, 530W, integrated. (0918) 5359528.

Once there also was an advertisment for an A400x:

4/23/2004   PIONEER INTEGRATED AMP. 8,500 A400X, mint/orig cond. 874-4553.

Other nice pioneer advertisments:

thanks for the tip. however, the pricing is similar to my source in Cagayan de Oro for preamp valves. for the power amp section, got my valves from a warehouse staff here two years ago at P10 each. i still have to check though if they're working since they were pulled out from an old Japanese tube amp, a W-41 Trio-Kenwood i think.

i have an Accuphase E-302 (120wpc) and i'm happy about its performance despite a slight cap problem. compared with Luxman, Accuphase is a premium brand costing twice, or three times, when brand new. ito lang yata ang truly high-end brand (outside of Ongaku tube amps) recognized by audiophiles in the US and UK as comparable to their best.

mga sir's,

I got this AV receiver for Php. 5,000.00 (prologic nga lang), here in one of the thrift shop in Evangelista, Makati.
I think it is also from Japan, the back panel is 100V, at 200W.

Can someone advise mo on where I can buy a 100V transformer? coz when I use my current 110V stepdown, it is really getting hot, is it safe to use a 110V stepdown?...

I'm also looking for a remote control for this reciever...

the model is "YAMAHA DSP-2000" I think its counter part in europe is "DSP-E1000"...

Anways this is how it looks...

hi,
if i were you i'd have that converted to 220volts, cost is about the same as buying a transformer. you can de-install the power transformer and bring it to Podmon in legarda for the conversion.

this way, murphy is excluded from your avr. ;D
Title: Re: Surplus amps
Post by: sandawa on Dec 19, 2005 at 08:32 AM
Yamaha DSP 2000 at P5K is quite reasonable (current Yahoo Japan re-sale value: below 10,000 yen). my only problem with Jap AV amps is that you need the original remote control units for them to be fully functional. controls for most of these amps are not available on the front panel (including the hidden buttons inside the flip-down covers). but i understand spare remote units could be ordered by mail from Yamaha Japan (check the local Yamaha dealers, they may have an RC unit that would work on that model).
Title: Re: Surplus amps
Post by: hattori_hanzo on Dec 19, 2005 at 09:12 AM
Your right sir 2ny had problems with the controls, cant adjust them at all. plus when I'm using the prologic enhance the center is to loud, cant even notice the sound from my L/R fronts. the seller of this unit has a remote control but the bad thing is he wont sell it. sana available ang remote locally...

Original quote for this is Php 7,5T got it for Php.5T and it is really heavy (12kg) almost had a arm dislocation from carrying it hehehe... The sound is quite good naman the reason why I bought it is because of the DSP's and the Prologic. I had a konzert 502A but im not happy with its prologic decoding "kuno" so Im just using it for loud music. plus I heard YAMAHA AVR that are made in Japan are durable...

One more thing Sir Sandawa, the amp is really getting hot but it performs well naman, yun lang ang problem ko umiinit talaga is it because of the 110V transformer? I want to keep the orginal 100V sana kung where can I buy a 100V stepdown, please need help...

hans,

is this the specs of your amp?

Specifications DSP-E1000

Minimum. RMS Output Power (8 Ohms, 20-20,000 Hz)
Front Channel Does not provide main channel
Centre Channel 80 W (0.015% THD)
Effect Channel 25 W + 4 W (rear/front) (0.05%)
Pre Out Terminals Main, Centre and Effect Channels
Subwoofer Outputs
Duel Centre Speaker Capability
Remote Controllable Master Volume Motor-Driven with LED
Direct DSP Programme Access
Dynamic Power/Ch (8/6/4/2 ohms)
Damping Factor (8 ohms 20-20,000 Hz)
Frequency Response (20-20,000 Hz) +/-1.0 dB (pre out)
THD (8 ohms, 20-20,000 Hz) 0.005% (centre, pre out)
Signal-to-Noise Ratio (CD) 96 dB (tape monitor)
Dimensions (W x H x D) 435 x 131 x 386 mm
Weight 12 kg

Wouldn't it be the reason that you get a louder center channel than the mains since it is mentioned in the specs that that it is a 80Wx1 (center) and 25wX4 (effects) amp?  I remember during Yamaha's AVR "pro-logic" days that they use have a 2 FRONT EFFECTS channel and 2 REAR EFFECTS channel, like for the 795 model ata.  Does this mean you may need a 80x2 W MAIN channel.

Just curious. ;)
Title: Re: Surplus amps
Post by: sandawa on Dec 19, 2005 at 08:12 PM
this is a correct observation. the Yamaha DSPs (digital sound processors) need a main stereo amp to perform according to specs. manuals for DSP models, i think, are available in the Yamaha website free to download.

Post by: Lord Foo on Dec 20, 2005 at 05:08 AM
The Pier Surplus outlets sell those 100 volt step down transformers. You can get them in various wattages. I am not sure if i recall correctly but the 200+watter goes for about 250+ pesos while the 400+ watt transformers goes for about 400 Plus pesos. I suggest you get the higher wattage transformers in case you need to power more than one unit.

I've been seeing a Yamaha DSP2000 in one of the pier outlets for several months now. It was being quoted at 8000 pesos then. Its probably still there now. Its in the last outlet after Little Chatty's.

Some of the Japanese surplus units that i own have provisions for easy conversion to 220 volts with just a few re direction of the power source wirings by a good technician. After a few accidents, I've preferred conversion to using transformers whenever possible. (Yes, i've properly labelled all my 100 volt electrical plugs and Murphy still exercises his Law.)

yes, murphy is hard to avoid at times, ;D i remember in the early 90's when i still have this repair shop, a friend was bragging about the portable boom box his wife sent him from japan. so i told him, bring it in for conversion, it will only cost you 250, but before he could do that, the maid plugged the thing in!!! so he spent 2500 to have it repaired! ;D

mral of the story, keep murphy out whenever you can.

is this the specs of your amp?

Specifications DSP-E1000

Minimum. RMS Output Power (8 Ohms, 20-20,000 Hz)
Front Channel Does not provide main channel
Centre Channel 80 W (0.015% THD)
Effect Channel 25 W + 4 W (rear/front) (0.05%)
Pre Out Terminals Main, Centre and Effect Channels
Subwoofer Outputs
Duel Centre Speaker Capability
Remote Controllable Master Volume Motor-Driven with LED
Direct DSP Programme Access
Dynamic Power/Ch (8/6/4/2 ohms)
Damping Factor (8 ohms 20-20,000 Hz)
Frequency Response (20-20,000 Hz) +/-1.0 dB (pre out)
THD (8 ohms, 20-20,000 Hz) 0.005% (centre, pre out)
Signal-to-Noise Ratio (CD) 96 dB (tape monitor)
Dimensions (W x H x D) 435 x 131 x 386 mm
Weight 12 kg

Wouldn't it be the reason that you get a louder center channel than the mains since it is mentioned in the specs that that it is a 80Wx1 (center) and 25wX4 (effects) amp?  I remember during Yamaha's AVR "pro-logic" days that they use have a 2 FRONT EFFECTS channel and 2 REAR EFFECTS channel, like for the 795 model ata.  Does this mean you may need a 80x2 W MAIN channel.

Just curious. ;)

Sir yan nga ang specs, I think that is the counter part of DSP2000 sa europe. im having hard time using it without remote, I just dunno if I can adjust the speakers levels (eg. small or big fronts, LFE etc..) and also and room size kung may adjustment man ito, even sa main, center or rear speaker volume...

Plus im having hard time cant find the manuals...

The Pier Surplus outlets sell those 100 volt step down transformers. You can get them in various wattages. I am not sure if i recall correctly but the 200+watter goes for about 250+ pesos while the 400+ watt transformers goes for about 400 Plus pesos. I suggest you get the higher wattage transformers in case you need to power more than one unit.

I've been seeing a Yamaha DSP2000 in one of the pier outlets for several months now. It was being quoted at 8000 pesos then. Its probably still there now. Its in the last outlet after Little Chatty's.

Some of the Japanese surplus units that i own have provisions for easy conversion to 220 volts with just a few re direction of the power source wirings by a good technician. After a few accidents, I've preferred conversion to using transformers whenever possible. (Yes, i've properly labelled all my 100 volt electrical plugs and Murphy still exercises his Law.)
 

Thanks sir, I'll try to look for those stepdowns. Sir ganun ba talga ka mahal ang DSP ng Yamaha? I got this for 5T only but the problem no remote, the seller has a remote but he wont sell it, the reason? there might be a same unit will arrive sa shop nila kaya he wont sell it...

the good thing about this DSP, it sounded so good with the effects specially with GEQ, plus I want to replace my 502A with a prologic "daw" decoding... maybe I'll try to route up the front's preout with the 502A to power my L/R...

Mga sir's,

When I use ba a 100V stepdowns instead of 110V will it change my Yamaha A/V amp temperature? besides from modifying the AMP itself, how can I lower the heat being produced by the amp? 

Your comments and suggestion is highly appreciated!!!

Thanks...

Post by: egp on Dec 22, 2005 at 10:05 AM
based on experience changing the transformers to the recommended 100v will lower the temperature. used to have that same problem on all of my surplus amps but once i supplied those with the voltage required everything worked out fine.

Hello,

san ba pwede mag pa service ng mga vintage na amp?

meron kase akong nahukay sa bodega ng tito ko na integrated stereo amp (sansui A-5). nilinisan ko, gumagana naman, yun nga lng pag pinipihit ko kahit na anong knob nagkakaroon ng maingay na sound, tsaka pansin ko kahit na zero ang volume may lumlabas pa rin na sound from the left chanel..

meron ba kayong kilala na marunong gumawa? natatakot kase ko pagawa sa ib kase baka karnehin an parts, sayang naman.

Puwede ka magpa service sa Pier dun sa Little Chatty's. Sabihin mo sa technician na lahat ng parts mangagaling sa iyo. This way puwede kang bumili ng original parts. Medyo matagal nga lang itong process na ito dahil hindi gagalaw iyung tech hanggang hindi mo nabibili iyung parts. Kung mangagaling naman sa kanya most probably galing iyung parts sa isang vintage na amp din. Siyempre kapag luma, most probably konti na lang itatagal.

Baka dun sa Pier meron. Hindi ako sure sa Quiapo.

Base sa description mo, ang problema mo lang yata ay mga knobs/pots. If so, marami kang makukunan nito. Puwede rin linisin mo mga ito baka maayos mo. Dun naman sa isang channel baka mataas na biasing. Si 2ny magaling dito, nandito rin sa thread na ito iyung mga guidelines niya tungkol sa mga pots and biasing adjust. Iba kasi linya ko.

hey rascal, you may find it odd, but i also do repairs/upgrade for pc psu, and my favorite source of parts are the sidewalks of raon! i am more confident buying them than from say, deeco ;D

and parts coming from vintage amps are no issue imho, specially power transistors, small signal ones are easy, they can be replaced at will.

ss devices unlike tubes does not suffer from emission depletion over time, they are either good or they are bad, seldom in between.

it is doubtfull that temps will be lower when using 100volt stepdowns, temperature is a function of idle current setting, so setting idle currents to a lower value will definitely decrease temps.

you can open the hood, then apply contact cleaners on the switches, volume and tone control pots, this should fis the problem, no need to send the unit to a shop fopr repairs. you can diy it. be carefull though not to dislodge anything or apply preassure on any parts unnescessarily.

Thanks sir 2ny....

Sir, another question, is there another way of lowering the amp's temperature? sir efficient ba yung pag lower ng voltage supply (particularly 100V stepdown) will it be felt? wala kasi akong instrument to test this, except an external digital thermometer....
Title: Re: Surplus amps
Post by: ATJr. on Jan 03, 2006 at 07:43 AM
changing your transformer to 100volt is no guarantee that temps will go down, it could be that voltage in your place is high, say 230volts and above, so temps are still high. or you may have a 110volt meralco power yet the voltage is 200 and below, then your amp may have decreased temp.

aside from idle current adjustment, you can also install small fans blowing into the heatsink to manage the temps to comfortable levels if you do not want to adjust pots.

I'm afraid I will not take this chance at Raon unless I don't have a choice.  ;D Too many customer failure analysis in the past.  >:(

The only parts I buy from Deeco are small signal transistors and diodes. The rest, free samples   ;D  ;D from component suppliers or from my pocket - I buy from RS components, Farnell or from China (I ask some people to buy for me).

Anyways, some experiments are based on my previous experiences in the office. So I no longer have to tweak around. Some small experiments I use Simetrix.  :)

THANK YOU FOR YOUR ADVICE!!!

Effective nga ang gumamit ng 100V stepdown instead of 110V, my DSP-2000 is now cooler than ever...
I match it with the amps specification. 200W at 100V. got the transformer at Raon for Php. 550 branded as Matchbox with lifetime service warranty...

Salamat ulit Sir 2ny for the advice on "how to cool your surplus amps!"...

gusto ko lang i-share..kaninang umaga napasarap ang pakikinig ko, naphit ko sa 12 o'clock ang volume knob, at nagulat ako nag iba tunog ng speaker ko, parang sasabog...sumobra sa high tapos nawala ang base, basta kakaiba..pero pag 10-11 o'clock setting ok naman cya.

ganun b talaga kalakas ang 25 watts per channel? gamit ko sansui a-5. kase sa avr ko 45watts per channel pero d ko na-experience yun kahit -15db volume level. e sabi na nga nila na yung avr na gamit ko high current yun...or dahil wala akong sub na kinabit dun sa sansui set up ko kaya nag kaganun at bookshelf lang yung mga speaker ko? tama ba?

ano ba kelangan ko i-check para malaman ko kung may na damage sa mga speaker ko? o pano ba malalaman kung sira na yung speaker?

nakalagay nga pala sa manual ng speaker ko:
Recommended Power Amplifier Range:  10 - 100 watts 
Title: Re: Surplus amps
Post by: ATJr. on Jan 04, 2006 at 11:13 AM
what you experienced is your amp clipping! power supplu ripple is coming thru minimising bass, your tweeters are the forst to suffer from this! just back off and you should be ok.

you will know if your speaker got damaged when the tweeters do not sound the way it did before!

do not worry about speaker wattage so much, it does not mean anything much to me.
it will always be the amp that will run out of steam before your speaker does , as what you have experienced.

yes, clipping is a function of the amp's power supply vis a vis the input signal, if input signal is such that the amp can no longer supply power, then clipping occurs.

the amps will clipp first before the speakers reach their limits!

Sa akin kasi konti lang sira. Pero you can source your parts at RS components (matagal lang delivery  :(). For e-caps you can try Eleshop but for high end there is a thread in pinoydvd for Black Gates capacitors. For resistors Alexan, DEECO, etc. For semiconductors Akihabara in Raon or Caloocan (near circle and very near to 711).

i need help on my audio set up, theres a clipping sound whenever i turn the volume up to 10 o'clock pa lang parang may nilulutong pop corn s loob ng speaker, tpos pag pinatay ko @ binuksan ko ulit may pop corn pa din kahet zero na yung volume? im using a trio ka-7300 driving an aurum cantus f6600.

the first time i encounter this prob i immediately turn my amp off, tapos binalik o agad sa pier (little chatty) yung amp para ipatest. when they test it sa pier ok naman hindi nag clip for 3 hours @ 10 o'clock volume!

f6600 is 4ohms & trio ka-7300 is rated 4-16ohms around 85w/channel i guest, im using a 12ga generic wire( if this matter) ???
guys i need ur help very badly, pls :(

can anybody tell me where to contact sir jojod, para mapatignan ko po yung amp ko?
than you so much po in advance for ur help!

Title: Re: Surplus amps
Post by: sandawa on Jan 11, 2006 at 07:50 PM
i don't think it's clipping. what you need is re-capping. usually that distortion disappears after awhile. if it's still there even when the amp is already warm, you have likely a bad case of dried capacitors. KA-7300 is a very good vintage amplifier, don't throw it away. have it checked by a good technician. in the '80s the best Kenwood mechanic was in Avesco's main office in Roosevelt. 2ny, jojoD and the other techies here could probably help you, if you want to go DIY.

baka mali ang diagnosis ko. kung walang distortion pag switch-on sa Little Chatty, hindi capacitors ang problema. i test mo using another speaker or another wire. o di kaya, tanggalin mo ang wire ng speakers - tapos ikabit mo ulit ng maayos. wag ka munang mag-bi-wire, simple installation lang para makita mo kung talagang sa amp, pwede din na DC leak 'yan.

popcorn noise is indicative of a noisy small signal transistor, it will test "good" on a tester but replacing it ussually solves the problem, now what puzzles me is why it does not manifest itseld at the pier. ???

Post by: aHobbit on Jan 12, 2006 at 10:37 AM
I have an amp before bought by my father way back 1983. After certain years of use, a channel also exhibit the problem - pop corn noise. Since it is basically a  straigh forward amp design, I can easily take a careful inspection in the board - and incidentally discovered a terminal of a small transistor is floating from the PCB. I discovered it by putting test speaker in the problematic channel, and pressing gently each PCB component.

After soldering it back, the amp continue to be in use as of today. I am still wondering how such transistor could suddenly float out of the PCB - normal wear and tear?

Also I bought my Pioneer VSX3800 way back 1992. Last year, it also exhibit same problem on one channel. My first guess is the speaker protector, after I sprayed on all pots and switches. Still have no time to check on it now, but may try to do just what I did on the previous amp. However, I might have more difficulty since the model is already the pro logic type, the problem of having too much VLSI chips in the amp makes it extra difficult to diagnose.

The good surplus amps in pier could still be easy to diagnose IMO.

looks like the traders are monitoring our posts here, or at the PinoyAudio website. still, the difference in price between the 707F extra and the 707X-decade should not go beyond P1K. if it was a 907X decade, pwede ang P3K difference. hope they read this, so they would adjust their price.

I regret missing out on Sir Wanderlust's 907XDecade...

I have both the AUD707GEXTRA and the XDECADE. (for a still unrealized bi-amping project)

The difference in audio performance is very evident. The lows are lower and the highs are higher for the XDECADE and the sellers I  believe, know the difference. They base their price on the power consumption indicated at the back of the unit. The xdecade has 320watts and the GExtra has 270watts indicated at the back.

Look at the Back of an AUD707GEXtra. Its made of copper or brass while the XDECADE's back panel is painted black. I am not sure if it is also brass. I also note that the front panel of the 707FExtra of Sir Parasmi is silver (Sir Parasmi bakit po ang gaganda yata ng mga audio equipment na dumadaan sa mga kamay mo?).

I got my Xdecade for a lower price though because the wood casing was totally dilapidated. I replaced it with old narra wood I removed from my mother's wall paneling. I just stained the narra a little darker to approximate the dark mahogany finish of the original amp's particle board casing.  It looks better now with real philippine wood.

The xdecade has 320watts and the GExtra has 270watts indicated at the back.

this is the rating of the total wattage of appliances you can connect to the outlets at the back of the amps, no relation to actual performance.

Look at the Back of an AUD707GEXtra. Its made of copper or brass while the XDECADE's back panel is painted black.

actually it's copper plated cold rolled steel plate, while the other is painted black.

again this is not about power output, but gives some clues as to capacity. for lack of any other basis, sellers use this figures for convinience. is not a true measure of the amps' capabilities

Hi 2ny. Magandang gabi po.

I always thought that the wattage of the other components u can connect to the outlets is different from the power consumption rating. Aren't these the wattages indicated right below the power outlets on the far right of the back of the amp? The ones indicating switcced and unswitched on the far right.

What then is the wattage figure (270 watts) indicated right below the serial number at the center of the back of the amp? I always thought that they referred to the power consumption.  I used to divide the power consumption by two to get a ballpark estimate of the RMS rating of the amp.

hi,

the only sure way to know the power rating of the amp is to look for catalogues in the net. then if you do not have that, load testing the amp using 8 or 4ohm dummy load is the other way.

there was a time when the power consumption of appliances sold in the us were required to indicate ratings at the back, to give consumers a choice and so that they will be aware of how much energy is required. call it energy conservation.

if you are an ece engineer then you may open the hood and inspect the power supply, the main filter caps for example will give you an idea right away, measuring the rail voltages will give you a better idea, then dummy load testing.

it is the power consumption anticipated by the manufacturer that you will ever use with this amp. and with good speakers, i doubt you will ever see this power comsumed, more like 20 to 50 watts is realistic even with volumes at high levels.

notice also that your power cord is of the "dinky" type, what, a gage 18 or more often a gage20, so those power ratings are to remind you of limitations that you have to observe if you want to stay within safety limits.

Look at the Back of an AUD707GEXtra. Its made of copper or brass while the XDECADE's back panel is painted black. I am not sure if it is also brass. I also note that the front panel of the 707FExtra of Sir Parasmi is silver (Sir Parasmi bakit po ang gaganda yata ng mga audio equipment na dumadaan sa mga kamay mo?).


I got my Xdecade for a lower price though because the wood casing was totally dilapidated. I replaced it with old narra wood I removed from my mother's wall paneling. I just stained the narra a little darker to approximate the dark mahogany finish of the original amp's particle board casing.  It looks better now with real philippine wood.



nakakahanap ng mga good deals at tyempo tyempo lang, sir foo  ;D

what prompted me to buy the sansui, aside for the model, was its condition. super kinis pa talaga! may konting gasgas lang sa steel casing which can easily be fixed with the use of a spray paint. Some nicks at the bottom of the side panels but still in very good shape 

When I went to the pier last Friday, I was planning to buy the AU-555A which I saw a couple of trips back after losing the AU-777 (the first SS amp model of Sansui I think) to a lucky buyer. Pero umikot-ikot muna ako baka may mga bago na dumating. Kaya ayun, I ended up with the 707Fextra  ;D

here's a shot of its interior

also sighted and considered were the following

Sansui AU-D707X decade - dropped it kasi more than 3k price difference nya from the 707 extra
Marantz PM-80 - looks impressive kaya lang wala ako masyado info about it.

Will visit again next week baka may mga bago. If none, I'll probably get the same model (black faceplate) or the Onkyo.


Anyone been to the pier lately? Baka may mga sightings kayo dyan paki share na lang  ;)

Sir Parasmi, I visited the pier today.
Unfortunately, the sellers told me that there have been no arrivals lately.
The only nice amp i saw was a pair of Sansui AU5900. Black faced, they looked fairly new. Too low powered for me though so i left empty handed.

i have a surplus cdp and amp. gusto ko sana i-convert ito to 220v so as to prevent any accident. can anyone endorse a good and reasonable shop that can do this? tia
Title: Re: Surplus amps
Post by: ATJr. on Feb 10, 2006 at 08:14 AM
easy, have your technician pull out the transformers from the cdp and amps, taking note of the leads, cutting them so that a small part protrudes is a good idea, likewise write them down of a piece of paper for future refference.

now the transformers, you can bring to "Podmoon" in Legarda, look for Nelia,  for rewind and conversion to 220 volts, they have extensive rewinding experience and they have been in bussiness for about 50 years now.

this may cost you around 500bucks, i would say worth the money as you will spend twice or 4x that amount should an accident happen.

Podmon is along the road, right after bustillos towards mendiola.
WRT you denon, you can try cleaning the contacts of the selector switches. i am not too familliar with your unit, but if it is logic type, sometimes it scans the inputs for possible signal.

I didn't see any 707Fextra yesterday. (God knows I scrutinized every damn amp in every damn store in the damn place.  ;D Sir Parasmi must have bought the one einnoc2 (connie?) is referring to.

Sir Sandawa, how would the AUD707Fextra stack up against the alpha607i? The alpha is better than the AUD right?

Title: Re: Surplus amps
Post by: sandawa on Feb 11, 2006 at 09:47 AM
i don't know. i never had those amps. what i have now are 907F and alpha 907iMos. considering price quotes at Yahoo Japan for the two are almost the same (although alpha 607i is 90wpc while 707F is 105wpc, if i'm not mistaken) i probably would check my wallet, trust my ear and if it can't decide, toss a coin. that's assuming the price difference between the two is negligible. i think you're planning something not directly related to the question, acquiring another toy this weekend, perhaps?

BTW, saw your post on the Pioneer SA-810 at AK yesterday. it's the slightly bigger brother to the SA-710 i bought early last year at P700 bucks, good vintage gear, conservative power rating, nice wood cover - but should come cheap, probably not more than 5 times my acquisition cost!
Title: Re: Surplus amps
Post by: Lord Foo on Feb 11, 2006 at 08:38 PM
Hi Sir Sandawa,

(Medyo out of topic pero in response to the question, "you're planning something not directly related to the question, acquiring another toy this weekend, perhaps?")

Actually, I was hoping that an AR3a I was eyeing was still available at an audio sthop. Unfortunately it was gone when I came back for it.

I did get a new receiver a few hours ago. Remember my acquisition of a Sansui Quad QRX9001 Recever early this year? I am very fond of that unit and my interest in QUAD receivers have been kindled. I later dilly dallied in acquiring another TOTL QUAD Receiver, a Kenwood KR9040. It had problems with the right channel so I didn't get it. When I decided to get it. It was gone.

Today, I had the option of getting another TOTL QUAD receiver, a QRX949a. I didn't dilly dally this time. When I tested it at home, the sound output rivalled my 9001. I played a CD of Redentor Romero... I've never heard his violin so clear and brilliant with the pioneer. The Phone stage was also very good. However, one of four channels failed to produce an output. I hope i am able to have the problematic channel repaired.

The pictures and specs of the 949a are posted at the Vintage Knob. I will post pictures of my 949 later at the pioneer thread.

hi,

the fact that you are still able to use that amp after 30 years says volumes about the quality of pioneer amps.

4channel system came out but was short lived as the audio public did not support it that much, the way they did 2 channel stereo. it would be interesting to be able to use that on a 4 channel vynil disks.

Luxman hybrids hardly showed up in Davao. btw, those Luxmans were already part of the Alpine catalog and while it was quite popular here in RP, that series was not a big hit in Japan. LV-103, for instance was sold brand new at only 79,000 yen, way below the price of a pure solid state amp at same power range. current re-sale value of LV-103 in Japan is about 5,000 yen or $45.

Post by: Lord Foo on Feb 17, 2006 at 07:24 AM
Regarding the Luxmans,

I am not a Luxman expert except that I have  4 Luxman amps i can compare. Ever since Sir Sandawa advised me on the great quality of Luxman amps I have been on the lookout for them...
 
1). M120a power amp, Duo-Beta, 2x120W, (1980-83
2). L400,
3). L3 integrated amps, 2x42W, (1980)
4). and LV105u hybrid 80WPC into 8 ohms (105w into 6 ohms), with low impedance compatibility
5). even a nonworking LV100 i got dirt cheap. (I initially thought the LV100 was an L100. Its a different dog pala altogether.)

The m120a is a great unit. I am still looking for a pre-amp though. The unit has separate controls for left and right so it can be used without a pre-amp. I use it with an old Citation eleven preamp.

I gave away the LV100 to a brother. He's trying to convert it into a gainclone amp.

The L400 and L3 are well used. The Bass seem inordinately low, solid and loud for the low wattage of these two amplifiers. I use them in small rooms. Sometime ago, my brother used them for a biamp setup that worked fairly well. (This is the kind where he just connects a tweeter plus midrange to one amp and the bass woofer to the other amp. No separate crossover was used.)

The LV105u i really haven't used a lot. There's a problem with the balance controls (which doesn't work) although the amp seems already set with equal left and right channels. I don't use this unit often because of the balance problem. It might get worse. And yes, I've also seen comments against this amp. It seems that some afficionados consider the tube part as just a commercial strategy since the tubes do not really enhance the sound. A review in Axel's Vintage Knob debunks these claims:

Read up on Axel's vintage knob site specially :

http://www.thevintageknob.org/LUXMAN/LV107/LV107.html# and you'd get a better idea of the LV10+ series.
Click on CN to read Zeljko's in depth review of the LV10+ series. Zeljko debunks some misconceptions about the hybrid amps in his review. To quote Zeljko's...

"In 1984 Luxman stunned everyone by introducing a mass produced tube-MOSFET hybrid integrated amplifer, into a completely solid state dominated world of mainstream audio - the LV-103 [1st one was the LV-104?]. It was then followed with a tube hybrid CD player, the D-105. This unique line of components persisted in Luxman's lineup until 1992 and finished with the hard to find LV-107u. In 1986 Luxman gave it's already existing LV-105 model a full overhaul and re-introduced it as the LV-105u. It is widely accepted that the design really came into it's own with the untroduction of the u-postfixed amps, the LV-105u being the flagship until the LV-107u was introduced."

"The long production run of the series, however, shows that if the Brid units didn't make LUX a bestselling brand, it helped keep that glorious name fairly in sight until the early/mid 90s... The 1984/85 introduction of the LV-104 was received with a "Good Design" award from the japanese industry."



This unit is in the Japan Nisi site also.

All in all Luxmans are solid investments in my humble opinion. I've seen an 400 and an L410 being sold the past weeks in the pinoydvd forum. The L400 and L3 normally sells for 3500 up at the pier. Theres a LUXMAN POWER TUBE AMP. A3700, mint condition being sold at Buyandsell for 30,000.

Regarding Little Chattys...

Chatty's carry basically Japanese surplus units. I don't think quality of surplus units sold differ much among the stores other than the fact the Chatty's have more units. I often see a technician working on premise though at Chatty's and also in a small store inside the covered supermarket. This would imply that units with problems can be repaired quickly.

I would say that Chatty's has the largest inventory of surplus units at the pier now. I've observed though that their price is often higher than that of the other stores. They have several attendants so you can fairly quickly have the unit you want auditioned set-up and tested. The mother, father and son owners are usually there so pricing decisions are made quickly.  I bought my Yamaha NS690, two SONY Vfets, 2 Sony ES CDP, a Victor SX3, a Sansui AUD707GExtra, a yamah ca1000 from this store alone.

A tip if you are into collecting surplus gears...
 
try befriending the store handlers... slip them fifty bucks or a hundred bucks once in a while. This tip will get back to you ten fold when you are bargaining for lower prices. Get their cell numbers and txt them once in a while to get updates on what's available...Learn to sift between the sales talk and the facts they'd be peddling you... have the units been repaired? driver problems? amp repairs etc?

Saw a nice victor amp yesterday, its M-3030, dual mono, listed at Niji's. Tinuro ko sa tito ko, kinuha na kanina. Price is a bit steep, P8,500, pero maganda sa amp is that it's mono-mono, then parang class A at a certain output level. Can't get a grip on the babelfish translations.  ;D

Regarding the Luxmans,

I am not a Luxman expert except that I have  4 Luxman amps i can compare. Ever since Sir Sandawa advised me on the great quality of Luxman amps I have been on the lookout for them...
 
1). M120a power amp, Duo-Beta, 2x120W, (1980-83
2). L400,
3). L3 integrated amps, 2x42W, (1980)
4). and LV105u hybrid 80WPC into 8 ohms (105w into 6 ohms), with low impedance compatibility
 



Lord Foo,

Just wondering .... what combines best with your Kappas?

latest acquisition ==== SANSUI AU-607

just wondering though, why does it have 2 transformers? separate kaya power supply for each channel?

and why does the equivalent US version (AU-517) has a power consumption of 345 watts while the jap verson is only 185 watts? both are rated 65wpc into 8 ohms looks identical inside and out naman  ???

Reposting what I asked in another thread. I hope you guys could help me out.

I saw a surplus yamaha being sold here, and I was wondering if anyone knows anything about the unit. Its a Yamaha AVX 1000 DSP.

Not really sure if its a good receiver, but I would really want to know if it is.

Is this good for a starter setup?   ???

sir san mo ba nakita yan Yamaha AVX 1000 DSP? dito ba sa PDVD, parang hindi ko yata nakita, anyways I have a Yamaha DSP 2000 and when I checked the tech specs ng AVX 1000 na target mo. hindi siya published ng Yamaha similar din sa DSP 2000 ko. kasi limited yan sa Japan nang lumabas.

anyways magkano po ba binebenta sa inyo? kasi I got my DSP 2000 sa thrift shop here for 5k. pero sir, about the limited DSP series ng japan, eh kung bibilihin mo sure mo din na may kasamang remote, dahil lahat ng adjustments (eg. room size, spkr level, liveliness etc etc) eh sa remote lang na aadjust. hindi siya naadjust sa actual amp/reciever unit.

pero sa performance naman like the exclusive Yamaha DSP's, power dynamic range etc... eh panalo naman dahil hindi lahat ng AVR sa market meron nito...

happy AVR hunting...

Actually I saw it here in a surplus shop in Davao. Pero binebenta rin at 5k. Medyo may kamahalan nga ano if yours was at 5k. There were some Denon Amps din eh, check ko lang ulit model number. I'll try to go hunting again. :)

audio amps have "fads" just like jeans, dati uso yung bell bottoms nung araw, ganyan din sa amps, pioneer and others also came out with simmilar designs, at the time they thought that using 2 small transformers rather tthan a big one will improve sonics, and also make for a low silhouette design. times keep on  changing and with it amp design changes also.

try mo din audition yung DSP ng yamaha? kase kaya ako napa bili nito, dahil bukod sa perfrormace medyo matibay ang pagkakagawa (eg. DSP A1, AX1, AZ1, AZ9) puro flag ship yan ng yamaha. nung compare ko yung RXV series vs DSP. yung DSP lahat naka gold post, Rca etc. tapos yung built niya pulido talga ang pagkakagawa. unlike sa ibang RXV series medyo mukhang mas market ang pagkakagawa.

ang mahirap lang talga sa DSP ng japan eh limited pati tech papers ang hirap hanapin. pero for me DSP japan series are gold to be find dahil rare ito. (limited)

PIER na yun tapos pasok sa loob. hanggang dulo yun. you will see electronic sewing machine, TV's, window type AC, tapos sa bandang dulo. mag tanong ka kung saan yung little chatty's dun maraming choices, pero actualy madami din nagkalat dun. makaka tyempo ka ng maganda.

SANSUI B-2102 power amp - 200wpc

Although not acquired from the pier, still qualifies as surplus since I got it from a used audio store in Dau

Bought as is because left channel is busted. For 2k, i think its worth the gamble. Nasa doctor na as of now  ;D

similar to the B-2101 in built and appearance (i think)

if you can make both channels work at original configuration, you have hit the jackpot! that's still selling at over 70,000 yen used in Japan, almost at par with my Alpha 907iMos Limited. BTW, the more advanced B2102 Mos Vintage is even more expensive at roughly 90,000 yen, used.

now is a good time to change the driver and power transistors with modern types, lesser chance for getting fakes.
ask your tech about it, a check with newport or oriental for new devices will be worth your trouble and you will be rewarded with a better sounding amp.

finally, i would recommend that you replace all electros along the signal path with new ones, elna, nichicon and or rubycon are fine, they are available from eleshop in raon.

LV-109 could be TOTL in Alpine/Luxman line in late '80s but its average Yahoo auction re-sale value in Japan is low at 15,000 yen (same as LV-103u). Here are average quotes in the last three years for other used upscale Luxman units that have appeared or were mentioned on this forum recently, not necessarily TOTL: LV-107u - 30,000 yen,  L-530 - 25,000 yen; L-540 - 50,000 yen and L-570 - 70,000 yen.

But then again, if I saw an LV-109 in good condition and it's priced below five figures, I'd probably buy it. I think it is a good buy for a collector. It could serve as sample of Alpine/Luxman's equipment output since it took over the Luxman brand in early '80s.

I just bought a second hand JVC CD player from a fellow PDVD member, i want to buy a surplus integrated amp at the pier. Meron na bang mabibili na desenteng amp sa budget kong Php 2.5K?

Finally, i got myself an amp for my CD player. I bought it from a fellow PDVD member. It's a Denon PMA 920 which was accordingly bought in the US sometime in 1991. When i got it, it looked as if it's been from a bodega. The RCA jacks are heavily corroded (parang may asin) and when you peep inside, ganon din ang makikita mo at makapal na alikabok. Have it cleaned before i set it up. When i put it on and played a CD, wow my diamond 8.3 gave a new sound, buong buo ang bass, and i'm hearing instruments na hindi ko masyado naririnig before. At ang boses ng singer, malinaw na malinaw as if nasa harap mo lang sya. Ok na ok na sana, here comes the problem, suddenly one of the speaker went on and off and also gave unwelcome noise na parang static at medyo humihina. I put the amp off and wait for about 5 minutes to open it again and same problem occured. Inulit ulit ko yung same procedure and i noticed that minsan yung kaliwa at minsan yung kanan na speaker ang nawawala. Major problem kaya ito? Guys please help naman.

Have it cleaned before i set it up. When i put it on and played a CD, wow my diamond 8.3 gave a new sound, buong buo ang bass, and i'm hearing instruments na hindi ko masyado naririnig before. At ang boses ng singer, malinaw na malinaw as if nasa harap mo lang sya. Ok na ok na sana, here comes the problem, suddenly one of the speaker went on and off and also gave unwelcome noise na parang static at medyo humihina. I put the amp off and wait for about 5 minutes to open it again and same problem occured. Inulit ulit ko yung same procedure and i noticed that minsan yung kaliwa at minsan yung kanan na speaker ang nawawala. Major problem kaya ito? Guys please help naman.
try nyo po linisin yung volume control first. yung contact cleaner po na madaling magevaporate ang magandang pangalinis diyan. wag po kayo gagamit ng wd-40 dahil magaacumulate lang po siya lalo ng dumi katagalan.

joey is right, the pots probably just need cleaning. in my experience it's also worthwhile to check the DC-offset of newly bought vintage amps, whether Jap surplus or int'l/US units (which could likely be inferior to 100V units internally). DC leak could destroy HF speaker units.

Ok. Thanks i'll do that. BTW, where can i buy the contact cleaner and what particular brand you can recommend? TIA.

Another newbie question lang po. Yung Denon PMA-920 ko po ay merong A+B speaker out option, can i use both in bi-wiring (or bi-amping?) my Diamond 8.3? Which is better, bi-wiring using output A only or bi-wiring using output A+B?

I brought my Denon PMA-920 to my techie friend for cleaning as recommended by sir joey and sir Tony. My friend observed the behaviour of the amp for two days using a pair of 8 ohms 100 wrms bookshelf speakers. Covinced that the amp is ok already, my friend let me take the amp home. Pero pagdating sa bahay, when i set the amp and put it on, andoon pa rin paminsan minsan yung problema na nawawala yung sound pero this time sa left channel na lang. Yun bang tipong nasu-supress ang power at hindi makalabas. Pero dun naman sa shop ng friend ko while we were observing the amp, it didn't behave naman like that! Hindi kaya nagki-clipping ang amp ko dahil sa overload ng speaker?  But the amp says that it can handle 6 - 16 ohms speakers. And the amp is providing 115 wrms amplification for each channel. BTW, i am using Diamond 8.3 (which is a 6 ohms spker) in conventional bi-wiring. Pero yung problema ay hindi na tulad ng dati, minsan minsan na lang ngayon. May palagay ako na dahil matagal ito na hind nagamit (years daw) ng dating may-ari eh baka kailangan ulit ng break-in. Mga sirs ano sa palagay nyo? Kailangan ko bang ibalik sa hospital o obserbahan ko na lang muna?

Isolate the problem by

1. Try changing the interconnect cables or speaker cables
2. Try switching the speakers use the Right Channel speakers for your amps left channel
3. Could it be the source (CD or DVD ) and may problem ?

funny how I had a similar problem with my old amp, everytime I would bring the amp back to the shop it would "heal" itself, but once I got home it was busted again. Eventually the intermittent problem became permanent and the technician was able to fix it

Have tried # 1 and 2 already and it's the left channel that is really showing problem (although hindi na grabe tulad dati). I'm not sure about #3 though. Pero o-obserbahan ko pa rin and if symtoms persist, i think i should bring my amp back to the doctor. ;)

Finally, my Denon PMA-920 is now functioning well. Naisip ko kasi na baka dahil sa tagal na di nagamit e talagang heavily corroded na yung volume control, so once again i flushed contact cleaner to it. Pati yung mga speaker terminals as well as the rca jacks nilagyan ko na rin. Thank God, nag-sounds ako ng Saturday and Sunday at wala namang problema. Talaga palang magandang tumunog ang 8.3 if given the required power. The highs and the lows are perfect the way i wanted to hear it. When i put on my active sub (connected via the pre-out), wow parang na rin nasa Spectra. Lalo na siguro kung may enough sound defuser yung living room namin. Thanks again guys for the advise, malaking tulong.

Yung nasa likod, right side if you're entering from EDSA? the last time i visited that place was 10 years ago, wala, even the signages were gone. i saw a Sansui oldtimer sometime in late '90s working in Virra Mall who told me some of his colleagues were working in Raon and in Banawe, QC and some have already gone abroad. if a Sansui service center has reopened in V.V.

thanks a lot for the Sansui service center's phone number. i have a problem with an old AU-70, one channel's output is a bit weaker, and i don't want to tinker with it since it's a tube amp issued in 1965 (i've seen my dad hurt a few times trying to fix his tube amps in the '60s when i was a kid.) i don't think our technicians here in Davao can handle '60s tube gear. i'll bring it there in my next trip.

Sir pwede ba malaman anong amp ang pinagawa mo?  And what is the name of the tech?  I was there yesterday at about 9:10 kasi sabi nung nakausap ko sa phone they open at 9:00.  I had to wait for an hour bago dumating yung mga tao >:(.  There was another guy who had been waiting also, but probably not as long as me.  Sabi daw sa kanya pwede na makuha ung Sansui receiver nya, but it turned out naka-kalas pa ???  He was looking for a certain Danny, who I think was also the guy I spoke with on the phone.  Apparently this Danny is the only one who does amps because when I asked the lady in charge whether I could stay around and watch the check up proceedings she told me no because the guy who was going to do it wasn't around.  She said I should call back Monday afternoon.

Well the guy who was expecting to take home his receiver didn't seem upset.  I would have been if I were in his place!  But from his exchanges with the lady, I gathered he had probably been their client before.  In fact he was asking if a huge Sansui quadraphonic (is that the right term?) that had apparently been in the shop for a long time was available for sale.

The bottom line is that my experience with service shop didn't leave me too confident.  Yes the other tech who helped me bring in my amp was friendly, and so was the lady.  But I was hoping to talk with the actual guy who would fix my amp.  Add to this a small, lingering fear that my amp could end up being the parts source for some other project of theirs.  Or they could quote me an atrocious price in the hope of me abandoning my amp there and they could then sell it at a profit.
I know, I know...I sound paranoid ::).  But this has been know to happen in other service shops.

I had my Sansui power amp (B-2102) repaired there, sir. If you guys are in a hurry to get your gears fixed, I would suggest that you look for another tech since isa lang talaga gumawa (Danny) sa Soliven  :(

Based on my experience, they will quote you first of total cost of repair before proceeding to the actual repair. In that way, the customer will still have a choice of pulling out your gear or continue with the service.

I understand you sounding paranoid because I also had my share of bad experience with technicians whom I do not know. As for me, tiwala naman ako sa Fil-Audio (name of service center). So confident that I had my Onkyo amp and vintage Sansui stereo receiver brought there for check-up   ;D

I used the repair services of that EDSA service center about 10 or more years ago. In both cases the sansui units i brought came back to me in good running condition. Medyo matagal lang ang service kaya tawag ako ng tawag. Several times. Then out of the blue, ayos na raw ung unit ko. I agree with Sir Parasmi... wag dito pag nagmamadali ka. Luluha ka ng dugo. My units run very well for a long long time though.
Title: Re: Surplus amps
Post by: mandrake on Jun 01, 2006 at 08:33 AM
All's well that ends well :).  Got a text message from Fil-Audio yesterday at about 10:45 that my unit was done and the cost was 1,090.00.  Went there at about 2:00pm and sure enough my AU-D907X Decade was singing again!  Danny told me he had to replace some transistors in the pre-drive section.  He obviously has had a lot of experience repairing vintage Sansui gear.

Sayang I had to leave that same afternoon for an out of town appointment.  Won't be back 'til Saturday evening so I haven't really had a chance to test the unit longer than the few minutes I heard it playing at Fil-Audio.  But I have no doubt that Danny did a good job and he did it much faster than I expected.  Hmmm... I wonder if he reads this forum, or is even a member?? ;D 

So to all of you vintage Sansui (and maybe other brands?) owners out there, there are at least two of us PDVD members who have had recent, good experiences with Fil-Audio.  And if you add to that what Lord Foo has said, I guess this is one service center that knows what they're doing.

Hi Mandrake :),

Congrats for having a newly revived Sansui gear.
I myself owns an AU-9500 (type na type ni mike...), also had to repair it myself (pinagtyagaan ko itrace ang problem...), same case, had to replace some leaky transistors in the pre-drive section...one chanel goes to cracking first and then muting after a few minutes of playback. Medyo hirap lan gawin because they are not that service friendly,dami pyesa, dangling/short wires...

Hope to hear your gears!

Hopefully in the not so distant future pag ok na ang bahay namin pwede na mag-session.  Right now ayaw na ayaw ni commander mag-invite except for close relatives kasi magulo pa.  Kulang kasi sa budget para maayos lahat :(

Hi Squidball :),

Have not seen or familiar with the model.
But it seems, the 'pedigree' is same as mine AU-9500, some features may be retained or just removed.
The price is reasonable. Just check the conditions: cosmetics of panel, back printing, housing, etc.
Importantly, check the working conditions.
If all things considered, its now your call ;).
Post the pics once you get it...

Hi Squidball :),

Buying a surplus amp is really a 'lakasan ng loob' thing.
The mere fact that its even a vintage makes it worst.
Kaya lang, pag nahilig ka talaga sa bisyo na ito, lust will prevail.
I suggest u insist to audition the unit by bringing along your own source cd player and set of speakers maybe.
Test for a few minutes para kahit papaano ma chek...
Problems may really manifest after some time (but you can pray too ;))
Anyway, help is around the corner, like FIl Audio (good fdbk, yet havent tried them yet)
Its just that there is really something nice about a vintage audio gear,maybe character and the sparkling big knobs and toggles...
Who knows, with this purchase, will signal the start of a love affair for this kind of hobby...
Its really a gamble...IMHO ::)
Its up to u....
Goodluck!

Sir Mandrake,

Yes, my AU-9500 has three pairs of speaker outs. I used the A+B combination for my sala set-up and A+C set-up, if threre are family gatherings in the house to power up a remote pair of speakers (C) at the garden.
Cge, just give me a call...I will be available this weekend, plan to have my leave starting this Friday...pachek rin kidney stones....hehehe

Title: Re: Surplus amps
Post by: sandawa on Jun 16, 2006 at 06:37 PM
that's a good amp, late '60s model. your price is comparatively low -- that unit should sell at least P2.5K. the specs are a bit low, 16 or 18wpc if i could still recall my unit back in early '80s. the rating is conservative, thus it would hold its own against '80s to new production amps rated at 50wpc. use efficient speakers, preferably over 90db/watt. vintage/surplus speakers rated from 20 to 50 watts would be ideal, kahit gaano kalaki, 4 to 16 ohms walang problema. also, one weakness of '60s to '70s amps are capacitors drying up by now -- that would result in distortion. recapping could be an option, but if it's still working well, leave it as-is.

Sir Dana the Sansui AU-7500 is still there. Apparently the shop owners there dosen't realize the value of the amps that they have, (Imagine, a luxman amp for only 1.3K) yun nga lang may added risk n no testing, as-is where-is ang condition. It's really a gamble. But this is one gamble I wouldn't mind taking. Sana may extra cash pa akong pambili.  :'(

Title: Re: Surplus amps

AU-7500 is about 30 to 40wpc conservative rating, should be equivalent to new production amps rated at 50 to 70wpc. It was built early '70s and patterned after US MacIntosh amps. If it works well and almost mint, I'll probably pay as high as P4K for it.

Still selling at an equivalent of $250 used in good condition at Hifido -- Japan (http://www.hifido.co.jp/indexe.html) and at an average of $100 in Yahoo Japan auctions.

sir, tama yang plano mo -- kung makakahanap ka. malaki talaga ang diprensya ng Alpha 907 sa 907F, parang 3 to 5 times more powerful sa sound yung Alpha 907. meron din akong AU-XII, same rating sa Alpha 907 - 160wpc@8ohms/240wpc@4ohms - pero no comparison. i have over a dozen high-power amps here, pero yung Alpha 907 lang ang kayang mag-palabas ng deep clean bass ng JBL 4430 (2235H model 15-inch woofer). compared with that combination, nag-tunog entry level yung ibang systems ko. clean live performance sound, even at room-level volume.

sir, mahirap yatang maghanap ng Alpha 907 ngayon -- pero malay natin, baka may nagtatabi dyan. ako merong dalawa pero never will i sell these -- yung Accuphase pa siguro ibebenta ko, ito never. ang alam ko, walang lumabas na Alpha 907 series outside Japan na pang international market - kahit equivalent or downscaled versions. the top of the Alpha series that went out was 707 in UK quoted at 1,700 British pounds in 1995. Hifi Choice classified alpha 707 as "recommended" and rated better than comparable Pass Labs and Audio Note amps.

pero three years ago may nakita akong alpha 907 (hindi ko alam yung extension letters) dito sa Davao na gold tone. ang ganda! nag-quote sa akin ng P12K, tinawaran ko ng P8K, ayaw ibigay. kinabukasan binalikan ko, wala na -- pastor(?) na taga Cotabato ang nakakuha at P10K. sayang!

here are my vintage gems (pictures were taken before i installed them in their racks - kasi mahirap buhatin at over 30 kgs. each):

I remember a sansui AU-XII was offered to me for 8k. It was a glorious day seeing the behemoth in pier in all its glory - it is a good vintage - I passed, knowing its inherent design problem. But for those who can manage to control the gear, excellent sonic reward awaits them. Congrats!

I ended up owning a 60wpc NEC-A10II - dual JFET monoblocks for 4K. convertible integrated-separate, all sealed alpha pots. Am not using them for now - but will not also sell the unit.

I also have the Au-D607Xdecade, AU-alpha607i, and AU-alpha507i - inspite the abuse it gets from where it is being used - very reliable animals ... and they have captivating glossy piano looks.

recently visited Pier and here are the reports:

there are a few units of Sansui AU 607 just scattered around shops and one AU 607F. A Sony 333ES, Pioneer A980, Aurex SB and there are also Trio's, NEC and LoD's. there are also recently arrived kevlar speakers from onkyo bookshelfs (90db) to floorstanders.

And heres a good new's to HT newbies... I saw 2 units of Dolby Digital / DTS receiver. Pioneer 7 series (forgot the exact model) and a Yamaha HTR-595a, but the bad news is... these receivers are quoted a bit high. 9k for the Pioneer and 10k for the yamaha. both are in gold finish. but I think still negtioable. (pakita mo lang yung cash at hand dahil matumal ang bumibili ngayon off season eh hehehe)...

maganda yang NEC-a10II, it's also a collectors' item. BTW, there's an auction record of alpha 607 in US' Orion Bluebook. sold in the US new at $1,760 in late '90s and current re-sale value is a little less than $500.

The area is called South Harbor or Pier.  Coming from the south using Roxas Boulevard, turn left at the first stoplight after Manila Hotel then turn right in the first corner.  Go straight until you reach the last perpendicular road (I'm not sure if this is called 9th St or 12th St).  Anyway, most of the stores are along this road...tingin tingin ka muna (better if you'll just walk).  Goodluck on your hunting! ;)

It's right accross a rotunda, I think it's called Anda Circle, along Roxas Blvd.   On the opposite side is the entrance to the Manila Cathedral and Intramuros.   From the South or Luneta park along Roxas, you should pass an intersection to Manila Hotel, then another intersection with Bonifactio Drive where the huge Petron Station is at your left, then farther along, you'll come accross this rotunda.  Go around it to your left you won't miss the sign Pier Shopping with all those jeepneys parked waiting for passengers.

Hi Sir Sandawa,

I've read your post and link (in audio karma) about the sansui  Alpha 777DG being the equivalent to AU-X911DG in the japanese demestic and international market. Been trying to get more information about this but struggling. Someone is selling this and was wondering if you or anyone here would have a guage of the reasonable price for this unit. Its 4 channels I believe.
 Here's the attached pic:

Title: Re: Surplus amps
Post by: sandawa on Aug 26, 2006 at 08:30 AM
I think it's a 2-channel amp. The 777DG is a variant of the Sansui alpha series, which is roughly equivalent to the regular alpha607 line. My hunch was that Sansui's intention was to release it to the international market as a downscaled version of alpha707, thus its power rating similar to alpha607.

Japan Yahoo auction records are not accessible at the moment but Hifido qoutes alpha777DG's current used price at 29,000 yen. Hifido is the largest retailer (online included) for used hifi in Japan. What it does is buy, recondition, and re-sell hifi units, thus it uses a standard pricing. Yahoo Auction pricing is based on direct transactions between sellers and buyers and thus lower than Hifido quotes. (In the US Orion Bluebook, X911DG was quoted at $228 current used price from $1,250 original retail price in 1989.)

Using Hifido figures, an equivalent of $290 in peso terms could be reasonable for alpha777DG. If the Japs are buying alpha777DG that much, we're lucky to be offered that price considering transporting the unit from Japan entails incremental expense. But since its performance is not quaranteed unlike units from Hifido, half of the above figure would be a good rate" -- that means a maximum of P7K.

Post by: southpeak on Aug 26, 2006 at 02:20 PM
been searching this thread for quite sometime now but can not find any decent information regarding Lo-d (Hitachi) audio gears. my first surplus gear was a marantz pm-54d from cubao near isetan.  displayed with it were some sansui, pioneer and yes Lo-d. madalas eto yung mga nasa ilalim ng patung-patong na mga amp na mahirap kunin kasi wala namang nag tatanong kung magkano. i’ve been to the pier also but was not lucky enough to catch any big fish.

but my perspective about the brand change when i happen to stumble upon the HMA-9500 mosfet power amp. the previous owner did not mention that the unit was from pier but said “puslit lang po ng boss ng ate ko from japan”.. same thing, di lang dumaan ng pier. so its still surplus…

being used as power amp for street disco dancing according the seller and was still in good condition.. yung malalaking speaker pa nga ginamit nya para e demo.
to make the story short, it’s the best surplus unit i’ve ever owned. i’m not sure about the other models though but if you happen to see a HMA-9500 and its in good working condition, grab it. my two centavos. some pictures of my unit and a reference site.

just be carefull, parts ffor that amp may be hard to comeby these days, especilally the power mosfets...

imho, some of the best amps from japan are not sony, sansui, marantz, nor pioneer, but those not famous here can deliver outstanding performance, you jst have to be patient locating them. besides, people at the pier do not realise their true value, hindi sila marunong tumingin...so getting them at low cost is a sure thing.

Greetings,

   Im kinda new to the surplus amp club and I own a Sansui AU-D907 Limited, and very happy with it  :D. may I know from our experts here what is the difference between the 907alpha. I know its a higher series. But that's all i know.    Thanks.
Title: Re: Surplus amps
Post by: sandawa on Aug 28, 2006 at 08:07 AM
I'm not an expert but I have 2 alpha 907s, a D-907F and an AU-XII and as I've mentioned the alpha 907s sound significantly more powerful than the D-907F and even the AU-XII. Why, I don't know except the original alpha 907 weighs 30kgs. (the imos Ltd weighs 32kgs.) and uses toroid (the D-907s weigh from 20 to 26 kgs. mostly with traditional EI transformers) although the caps rating in alpha is less than 80,000uF which one finds in the D-907s. In my collection of amps, only the alpha 907 could properly drive the 15-inch woofer in the JBL 4430, whose recommended power to sound its best is 300wpc RMS @ 8 ohms. The 4430, I was told a long time ago, was the waterloo for many tube users since its woofer is power hungry. BTW, alpha 907's sound reminds me of vintage Krell and Stasis heavyweights -- my dream amps -- I auditioned in the US back in mid-90s.

Going to another topic, Southpeak has proven that a patient hifi enthusiast could find gold in Metro Manila's used market and at reasonable price. Previously, there was this belief that the heaviest upscale vintage Jap equipment only lands in Davao. I still remember when he asked me about the LoD HMA-9500 early this year and I envied him for his find since it was a sought after model even in Japan. Despite its comparatively modest power rating, it was I think Hitachi's TOTL power amp during its time with premium-grade parts and timeless design/appearance. Anyway, Ben also owns a Sansui AU-111 valve amp made in the '60s, now a collectors' item, and many other high-end equipment -- better in quality and higher in resale value than those I own.

Here's a trivia. Ever wondered why Hitachi used LoD for its domestic brand? Hitachi, a certified sogo-sosha (giant Jap trading firm) wanted a unique name for its audio line considering it has so many products including personal care and small home appliances. The race was for the "lowest distortion" amp that could be developed. (Remember, it was shifting from the tube amp, which traditionally has high measured distortion) Hitachi's low-distortion objective became the brand: Low D; eventually becoming "LoD."

Toroids have less weight than EI for the same power rating.  For it to be heaveir than an EI, must have greater power rating.

Post by: ATJr. on Aug 28, 2006 at 09:39 AM
Hitachi is one of those companies making their own semicon devices, together with Sanken, Toshiba, Fuji, NEC, Sanyo, Matshusita and Sony.

try looking at the voltage specs of the main filter capacitors, the voltage rating on the caps body will give you a more or less accurate power capability of the amps.

the positive and negative rails will surely give you a definite clue as to power ratings. just to give you examples:

rails of +/- 35volts will give you about 40 watts at 8ohms,
rails of +/- 42volts will give you about 80 watts at 8ohms,
rails of +/- 55volts will give you about 120 wattts at 8ohms,
rails of +/- 75volts will give you about 200 watts at 8 ohms,
rails of +/- 85volts will give you about 300 watts at 8 ohms,
rails of +/- 160 volts will give you about 1500 watts at 8ohms.

so if you look at the filter caps you will surely get an idea as to its power rating.
 there is more, the number of output power devices will likewise give you a clue as to the robustness of the power amps, while many amps get by with just a pair for a stereo setup, this indicates that the amp is most likely for 8ohm loads only, amps rated for 4ohms will have more than just a pair of output devices.
Title: Re: Surplus amps
Post by: sandawa on Aug 28, 2006 at 10:20 AM
Thanks for the cap voltage-watt rough estimate. i know they're closely linked but never had such guide (as your example) before. The D-907s, like the AU-XII, have 4 big caps per channel at 10,000uF -- 8 all in the power section but I didn't take note of their voltage rating. A puzzle to me is alpha 907's caps have only a total of roughly 60,000uF with 2 big caps plus 1 slightly smaller cap per channel -- 6 all. Could it be that aside from the toroid, the voltage at the caps, and probabaly a different power amp design resulted in the significantly more powerful output?
Title: Re: Surplus amps
Post by: ATJr. on Aug 28, 2006 at 11:06 AM
the choice of which components, caps in this case, to use depends on, availability, costs at the time of the design and production run of the amps, i can not think of any other consideration.

ah, amps rated for 8ohms will have lower capacitance values than amps rated for 4ohms, likewise, caps will be smaller in value for amps rated at 40watts say, than that for 200watts say.

Toroids have less weight than EI for the same power rating.  For it to be heaveir than an EI, must have greater power rating.

rails of +/- 160 volts will give you about 1500 watts at 8ohms.

so if you look at the filter caps you will surely get an idea as to its power rating.
 there is more, the number of output power devices will likewise give you a clue as to the robustness of the power amps, while many amps get by with just a pair for a stereo setup, this indicates that the amp is most likely for 8ohm loads only, amps rated for 4ohms will have more than just a pair of output devices.



Sir TonyT,

What is the formula u used to get that estimate?Mahirap i-memorize them ;D. Is it (VCC^2/RL=8ohms)(efficiency factor)?
Also, just by looking at the Filter Caps,  is it safe to say that the working voltage label is about times 2 of the actual?
Trying to refresh my electronics...wala na kasi sa mainstream e...

Thanks

the formula is not that important,i do not memorise them, ;D it is the principle involved that will guide you through.... ;D

for sine waves: Erms = Vpk to pk/2.8, example, 220volts = 630/2.8,
Vpk to pk in our case is the absolute value of +/- Vrail, so a rail of +/-35 = 70volts. this is first consideration.
we also need to take into consideration the saturation value of the output transistors which can be 2.5volts say, and also the regulation of the power transformer used. these are taken into consideration when designing power amp output stages.

are you still with me? ;D

now Erms = 70/2.8 = 25

for an 8ohm load power then becomes P = (Erms)sqaured/8ohms = (25x25)/8 = 78 watts

so then why is it that i said it is good for 40 watts?

it is because, the 25volt is ideal, in practice we will get lower than than 25 volts because of sag in voltage of the power transformer, losses in power transistor output, and distortion limitations.

look at it this way, suppose the amps has two capacitors with lables, 47,000/50volts, then we know right away that the rails can not be 50 or more volts, it will be less, up to 35~42volts most likely.

Title: Re: Surplus amps
Post by: av_phile1 on Sep 05, 2006 at 09:09 PM
That shouldn't be too difficult.  I was amazed  google returned sites that are clearly unanimous about toroids being more efficient - just confiming, affirming with unmistakable unambiguity what my professors and textbooks told me 30 years ago.  ;D  It was interesting to relearn online. I'll let them speak for themselves.

Here's a sampling from specific manufacturers:

The key to all toroidal transformer advantages is its efficiency. (http://www.plitron.com/pages/advantag.htm)

Toroids are far more efficient than conventional laminated types. Toroidal transformers can offer extremely high efficiency, and figures of 96% and better are achievable (http://www.plitron.com/pages/technote.htm)

The toroid is the ideal shape for producing a transformer with the minimum of material (http://www.airlinktransformers.com/toroidal-transformers.asp)

Gaps are bad in most power transformer applications. Tape-wound toroidal cores don’t have any  (http://www.bryston.ca/newsletters/85_files/vol8is5.html)

Toroidal transformers are quieter and more efficient than conventional EI transformers .... (http://www.toruspower.com/technology.htm)

The magnetic flux in a toroid is confined to the core, preventing its energy from being absorbed by nearby objects. (http://www.tabtronics.com/TECHNOLOGY/ElectromagneticBasics/ToroidalTransformerBasics/tabid/112/Default.aspx)

Because they are more efficient, toroids are generally up to 50% lighter than conventional E-I type transformers (http://www.nictec.com/custom_magnetic_products/custom_toroidal_magnetics.asp)

The circular tape wound core, with no airgaps, and with primary and secondary windings uniformly distributed around the core, "locks in" the magnetic field and makes the transformer very quiet and efficient. The overall efficiency is typically 95%. (http://powertronix.com/html/toroidal_advantage.html)

40% more efficient than EI type. (http://www.audionut.com/pk4/store.pl?view_product=51)

Toroidal Power Transformers are made with tape wound cores. The tape wound cores provide an almost perfect magnetic circuits to minimize losses, fringing, leakage, distortion, and provide good magnetic shielding. It also decreases the magnetization force required to produce a given flux density. It is much more efficient than E-type lamination cores (http://www.coilws.com/Toroidal%20Power.htm)

Due to its unique construction, toroids are typically between 15 and 30%more efficicent than the conventional type. Higher VA rating makes toroids more efficient (http://www.alibaba.com/company/10008283.html).


From neutral  technical discussions:

Toroidal Transformers employacylindrical core wound with a copper wire. This transformer does not suffer from magnetic fluxleakages which usually occurin the coil of thetransformer. Hence,thecoils of the toroidal transformers arecharacterized with higher efficiency,and there is no interference in operationby leakage fluxes originating in the coil.  (http://www.reedlink.com/ProductInfo~Productid~39378~ProductName~Toroidal-Transformers.html)

C-cores are not as efficient as toroidal cores, but are easier to wind with conventional coil winding machines. The overall efficiency lies between the E-I core and the toroidal......The toroidal core has no air gap at all, and is therefore more efficient (magnetically speaking)  (http://sound.westhost.com/xfmr2.htm)

Because of their construction tape-wound toroidal transformers are more efficient and produce less acoustical and electromagnetic noise than standard E-I transformers. (http://www.plitron.com/PDF/PQpaper.pdf)

The strip construction ensures that the grain boundaries are optimally aligned, improving the transformer's efficiency by reducing the core's reluctance. The closed ring shape eliminates air gaps inherent in the construction of an EI core (http://en.wikipedia.org/wiki/Transformer)

From a tube DIYer

l chose the Plitron toroidal transformer because of its exceptional bandwidth: -3 dB at over 200 kHz, the result of high primary inductance (the good stuff) and low leakage inductance (the bad stuff-- kind of like HDL and LDL cholesterol)-- much better than can be achieved with a conventional EI transformer. (http://www.normankoren.com/Audio/TENA.htm)

I probably could go on forever.  But this is getting to be a bore.     :P

what my professors and textbooks told me 30 years ago ... 40% more efficient than EI type ...  ;D


Honestly speaking, I refuse to doubt you.  ;D  ;D

based on the post, the toroid can have as high as 96%, and toroid is 40% more efficient than EI. doing the math, this puts the EI core at about 69%.  ???

If it is power efficiency you are talking about, this is easy
            Pout
eff = ------------- x 100
             Pin
(do you remember your textbook?)  ;D  ;D  ;D

And transformer (EI or torroids) are basically efficient motors averaging more than 90% in efficiencies. 69% efficiencies are worse than motors’ efficiencies averaging 70-80% - and this is simply not true!  :P

Our 3-phase HV adaptation transformers on our new 160KVA UPSs are not torroids. I look up at the post beside out building and really, I wonder whether it has an oil-cooled torroids inside it. I peek in the substation beside the former Manuela in EDSA/SHAW – could it be torroids in there? Honestly, I don’t know. I have to confirm with my brother in Meralco to verify it for me, and will report it back to you.  :-[  :-[

If you mean by efficiency as the amount of material you put into it vis-à-vis the power output, probably you are right  :o  :o  :o – but power losses, no, you’re not (they average basically the same as torroids)! SO this should clear that cloud of your ‘so called’ efficiency.   ::)  ::)

I will also ‘paste’ my source finding regarding the torroid performance in a sound gear – but will reserve it for now until I search my ‘mahiwagang baul’.  ;)

Also, your tube DIYer – whats the purpose of his torroid, for power output or for audio output? if it is for power output, I dont know what the bandwidth has got to do with it!  ;D  ;D  ;D If it is for audio output, oh well, its not my taste for amplification, sorry – but the tube amp need it by force, not by choice!

“In solid state it is generally accepted that a good toroid is the best thing going…”

It is? I must have missed that.

So you consider a transformer "a good thing" which has the following fundamental flaws:

1) no airgap (an EI Transformer invariably has a distributed airgap even if tiny) and very little iron in the core, leading to early saturation, waveform distortion and high sensitivity to DC offset in the mains and "flattopping" and which in the real world as a result run hot, often hum and are inefficient, unless extensive external circuitry is appended to offset these issues which do not exist in EI Transformers

2) low primary inductance which as a result stores little energy which could be used to "bulk up" the current flow on the rectification peaks (measure the primary current waveform of EI vs. Torroid to see what I mean)

3) Exteremely high coupling capacity between sections which makes sure all mains related junk sweeps right through the PSU and onto the supply rails.

4) Due to construction and the problems around high shunt capacitance and low leakage inductance makes snubbing out the ringing from the reverse switching all the more difficult

Given the drawbacks compared to more traditional shapes of mains transformers it strikes me that the only thing Torroids offer is more profit to the transformer maker and/or equipment maker as they are MUCH CHEAPER to make and in materials than EI Types.

I use torroids where I have no no real choice and fit the required circuits to reduce their drawbacks but would prefer to use EI transformers of suitable construction instead and to just connect them.

====

“So if Toroids are cheap to make why are they many times more expensive than conventional designs? Is it because a lot of us fall into the newer is better trap?”

It seems in the US the market supports a higher pricing for torroids than for EI Transformers, in Asia and Europe this is not the case. If cost/size/weight is a concern you fit a torroidal, if quality is more important R-Core, C-Core or EI types are used.

toroids aren't necessarily more expensive.

I agree with you on large cross EI section core....but there are advantages with toroids......far lower winding resistance and Z for the same VA with an EI and the regulation factor is nearly halved. What many don't realise .....most toroids are pile wound and have a temp rise limitation whereas a well wound EI can gracefully stew.

excerpts from
http://www.pearl-hifi.com/06_Lit_Archive/07_Misc_Downloads/Toroidal_Trans_Myths.pdf

I’ve been lucky enough to speak to a variety of high-end manufacturers about AC power, transformers,
and component design. Conversations with Richard Vandersteen, Mike VansEvers and Emil Rotar (Warner Imaging) have been most illuminating. Years ago, I never really gave power transformers much thought. The assumption was that because so many high-end manufacturers were using toroidal power transformers, toroids must be demonstrably superior. Imagine my surprise when I started noticing that many of the best sounding components I’ve experienced in my system have all had EI-frame transformers. Coincidence? I might have thought so before finding out so more about power and transformers. Now  I’m convinced that cleverly done EI-frame transformers could/should give us better sounding high-end audio components.

What are we discussing about? Torroids are better than E-Is as far as effeciency. What efficiency? If we are talking about power then ...

Efficiency = Output Power /( Input Power x PF)

To help you guys out, the mere fact that you have high leakage capacitance and inductance on torroids already shows who is more superior. However, it isn't that simple. Based on my experience with switching PSU, we only use torroids due to size constraints - you get higher permeabilities kasi on torroids vs standard E-I cores. Unfortunately higher permeabilities also translates to higher tolerance in inductance.

So whether you use torroids or E-I cores is entirely based on your application. If you have size constraints go for toroids otherwise go E-I.
Title: Re: Surplus amps
Post by: av_phile1 on Sep 06, 2006 at 02:48 PM
HIGH EFFICIENCY

The key to all toroidal transformer advantages is its efficiency. And the key to its efficiency is the core. The core is a continuous strip of grain oriented silicon steel, wound like a clock spring, under tension. It is annealed to relax the molecular structure which ensures that all grains are in the magnetic direction (unlike the old standard EI, with about 40% in the wrong direction). There is no air gap, resulting in a stacking factor of 97.5% of its weight. Since all the windings are symmetrically spread over the entire round, gapless core, a higher flux density is possible (toroidal transformers operate at flux densities of 16 to 18 kilogauss, while traditional EI transformers operate at 12 to 14 kilogauss). The magnetic flux is in the same direction as the grain oriented silicon steel core, thus achieving very high electrical efficiencies. Typical efficiency figures for toroidal transformers are 95% (e.g. 18kVA at 98% efficiency).

Other advantages:

LOW Mechanical HUM

Toroidal transformers are also acoustically quieter than EI transformers. The absence of an air gap typically provides an 8:1 reduction of acoustic noise. In addition the windings tightly envelope the entire core, effectively reducing magnetostriction - the main source of the familiar mechanical hum found in standard vertically laminated EI transformers. Compared to EI transformers, toroids are silent.

Low Magnetic Field.

Another type of noise is magnetic. Toroidal transformers radiate about 1/10 the magnetic field of EI transformers; this is, again, because of the inherent efficiency and unique construction. The windings which cover the core act as a shield. The magnetic field is contained doing what it should, transforming energy from primary to secondary. This may eliminate the need for special shielding and makes toroidal transformers especially suitable for applications in sensitive electronic equipment, such as: low level amplifiers, medical equipment, and near CRTs.

Low Offload Losses

It takes a lot less energy to maintain the magnetic field in a toroidal core. This is known as excitation or quiescent power. Toroids require about 1/16 the excitation power of conventional transformers. That's 1/16 the electricity required by EI transformers in standby mode. This can translate into big savings in large transformer applications such as industrial controls

Post by: av_phile1 on Sep 06, 2006 at 02:52 PM
Toroidal transformers are more efficient (around 95%) than the cheaper laminated EI types. Other advantages, compared to EI types, include smaller size (about half), lower weight (about half), less mechanical hum (making them superior in audio amplifiers), lower exterior magnetic field (about one tenth), low off-load losses (making them more efficient in standby circuits), single-bolt mounting, and more choice of shapes. This last point means that, for a given power output, either a wide, flat toroid or a tall, narrow one with the same electrical properties can be chosen, depending on the space available. The main disadvantage is higher cost.

A drawback of toroidal transformer construction is the higher cost of windings. As a consequence, toroidal transformers are uncommon above ratings of a few kVA. Small distribution transformers may achieve some of the benefits of a toroidal core by splitting it and forcing it open, then inserting a bobbin containing primary and secondary windings.

Light Weight

Because they are more efficient, toroids are generally up to 50% lighter than conventional E-I type transformers.

Small Size

A toroid's compact dimensions are always less than E-I type transformers. Furthermore, the height to diameter relationships can be adjusted by design.

Low Stray Magnetic Field

Because toroids have no air gaps and the field is enclosed by the windings, they emit very low radiated magnetic fields. Primary and secondary circuits are uniformly wound around the entire core.

Flexible Mounting

Several mounting options make toroids easier and faster to install than conventional E-I type transformers.

Low Mechanical Hum

Because the core material is tightly wound, welded, and insulated, very low noise is experienced as compared to conventional E-I units.

Flexible Dimensions

In the design phase, the height and diameter can be varied around any constant power requirements. This benefit is significant to any design requiring a slim line or low profile.

Reduced No-Load Losses

Where stand-by modes constitute a large portion of the operating cycle, toroids can save significant energy. These savings alone can justify the use of toroidal transformers.

Title: Re: Surplus amps
Post by: av_phile1 on Sep 06, 2006 at 02:57 PM
The Toroidal Core

At the heart of the toroidal is a highly efficient donut shaped core. To construct the core, grain-oriented silicon-iron is slit to form a ribbon of steel which is then wound, like a very tight clock spring. The result is a core in which all of the molecules are aligned with the direction of flux. Molecules not aligned with the flux direction increase a core's reluctance (the capacity for opposing magnetic induction), degrading performance to the level of common steel when the molecules are 90 degrees out of phase. EI laminated cores, which are stamped from grain-oriented Si-Fe, may have as much as 40% of the total core area perpendicular to the ideal grain direction, with another 40% acting only as a return flux path. This more efficient use of the core material in a toroidal can result in a size and weight reduction of up to 50% (depending on power rating), allowing the design engineer to innovate by exploiting the toroidal's small size, low weight, ease of mounting, and flexible dimensions.

Efficiency

Since toroidal cores are constructed of a continuously wound ribbon, there is virtually no air gap. The windings are evenly wrapped over the entire core allowing the transformer to operate at a higher flux density than in standard transformers. Toroidal transformers can operate at 1.6 to 1.8 Tesla (16,000 to 18,000 Gauss) while EI cores are limited to 1.2 to 1.4 Tesla (12,000 to 14,000 Gauss). The magnetic flux of the windings is oriented in the same direction as the grain-oriented core, thus achieving very high electrical efficiencies. Efficiency is a measure of a transformer's ability to deliver the input power to the load.

It has higher magnetic flux densities but generally the distribution is non-homogenous that is why the play on the inductance is higher. I would not argue on efficiency with you because there are ways to compensate for magnetic losses. Anyway these losses would not be as significant as semiconductor losses anyway. Also, magnetic losses are not easy to compute. Apart from copper losses other losses are not that apparent. In fact in our loss budgets, we don't even consider magnetic losses. The only thing we consider on magnetics is

1. Saturation
2. Thermals

Now whether using torroids translates to higher efficiencies should be taken in the context of design topology, board space and customer requirement.

Toroidal P ower T ransformers

Toroidal power transformers are used to convert power level voltages from one level to another.Toroidal power transformers have the following advantages

Toroidal transformers are noiseless and highly efficient in operation. They have dismal stray magnetic fields. Toroidal transformers are suitable for applications that necessitate tiny size and lesser weight.


The Toroidal Core

This high efficient core is placed at the center of the toroidal.To construct the core, the grain-oriented silicon-iron will slit to make a ribbon of steel that isvery tightly wound.The result delivers a core with all of its molecules aligned with the flux direction. The molecules that are not aligned with the flux directionen hancethe reluctance of the core. This causes the performance to be reduced such that it is equivalent to that of common steel, especially when the molecules are out of phase by 90 degrees.

Stray Magnetic F ields

The main reason for the flux leakage from any transformer occurs due to the presence of the air gap. An ideal magnetic circuit is free of air gap. In EI transformers, the air gap present at the junction of ‘I’ and ‘E’ is the main cause for the flux leakage. This flux moves around the surroundings because of the high reluctance of the air and the flux concentration in the laminations. Mounting holes and grooves found in the laminations result in aminimal quantityof flux leakage. A continuous ribbon of steel is being used to wound toroidal cores;hence,stray fields from air gaps are eliminated .

In addition, the copper core is uniformly encased by the windings of the toroidal transformer. Magnetostriction isthemain source of acoustic noise in the transformers which is reduced in the toroidal transformers by covering the solid ring cores with the windings.Audible noise will be reduced to a good extent by varnish impregnating the toroidal core and the copper windings.

Just to add ...

Our competitor on an 800W and 1.2KW psu is using EI core but we are using torroidal core. Our topology is way better than them - full bridge ZVS (zero voltage switching) but they are getting 1 - 2% better efficiency. BTW, they are using 2 FET forward interleaved transformer topology which is a rather old topology if you ask me. And by the books alone should get you about 3 - 5% lower in efficiency vs full bridge ZVS.

Ofcourse there are ways to  compensate for the inefficiencies of the EI types.  I am just presenting the points about the inherent superioity of the toroid as a transformer discussed in these sites which I recall sounded just like what I read in textbooks and what my professors said.  I am sure modern circuit topologies can compensate for any weaknesses in a component.    The fact that you have to compensate clearly indicates what it is compared with toroid.   The choice of which configuration to use is often dicatated by economics and practicality, rather than component superiorty. (Same with speakers, compromises are often made)   DIYers know how difficult it is to wind on those doughnut cores.  So if expediency is the way, as in many production faclities, it may be a lot faster and easier to use EI and compensate electronically than use a toroid that have yet to be wound. 

And just because you can achieve high efficiency ratings in the OVERALL circuit topology where the EI sits won't change the fact that,  taken on its own, outside any circuit topology, the toroid, done right,  has a higher efficiency by its very geometry and construction.   ;D

Post by: av_phile1 on Sep 06, 2006 at 03:36 PM
I have no problem with that.   Electrical and electronic components works as a TEAM to achieve an end.  While its weakiest link often determine how it will operate, other components in that circuit topology can be so designed to compensate or correct for whatever weakness a component has that by sheer economics must be in it.  In the same way that speaker makers often have to address the resonance of a speaker driver by notching out such resonances in the dividing networks, rather than using a more expensive driver without those particualr resonances in order to make the price user-friendly..   Used in the context of the right topology and application, I would tend to think that a well constructed EI can do the job, as they already do in many applications.   But that is no argument to debunk the already well-known fact that toroids are inherently more efficient, for the reasons indicated in those sites I pasted.   Such a fact is very well utilized by Bryston, Krell, Aragon and other brands in their power amps.   Again, arguably little to do with better sound quality, but I can see the advantage of using toroid in amplifier applications.  There may be exceptions, but you don't make rules based on exceptions.   ;D

Whether torroid or EI, basta ako ang alam ko...Less heat ang torroid xformer, pero sa audiophile application...EI ang mas madalas gamitin.  Depende kung sino at papaano ginawa.  Kahit torroid pa 'yan kung mga pipitsugin anywhere-in-china galing, walang binesa (no say).  Pero kung EI at Made in USA or Germany naman ito mas maganda...same thing in vice-versa.

Sa history ng amplification, legend na iyong TO300 na xformer as the best in terms of efficiency and drive.  Halos lahat ng modern xformers na lumabas ay nag-patterned sa dynamics nito.  Pero hindi ito torroid?

In fairness sa mga dounut-shaped xformers(torroid & super-ring), OK ito kase less lahat (heat, vibration..etc), but it doesn't make it superior. 

Again, practicality lang, wala nang masyadong complexity...I challenge anybody here...Tell me kung ano ang pinakamagandang brand & klase ng TRANSFORMER sa buong mundo, iyong wala nang tatalo sa design & dynamics nito...Ika nga ay Super & Ultimate Transformer (torroid, super-ring or EI)?

Read the sites I pasted, the consensus is also among professionals.

Toroids are not just used in high end audio where its efficiency provides better weight to flux density ratios and size to power ratios especially in powerful amps that can benefit best in weight reduction (like humans  ;D).   Check the Bryston and Aragon amps, among others.   The obvious fact that for the same electrical input and output KVA requirement, toroids provide a smaller footprint, wire turns and weight is evidence of their inherent efficiency.

Toroids are also extensively used in aerospace-grade gears where efficiency allowing the same better weight to flux density ratios are required.  In all the aircraft navigational avionics instruments I've worked with as an aircraft instrument specialist in my first job, none use EI.  Their manuals are unanimous in declaring the high efficiency of toroids over EI for use in sensitive avionics gears.  They confirmed exactlly what I learned in UP.  I read they are also used/preferred  in senstiive medical gears, but I have no experience there.

I can understand the aversion of many DIY people with toroids.  They are difficult to assemble, and often expensive to source. Anybody can wind an EI.  But Toroids require a lot of patience.  The resulting sonic difference may not even exist for all the trouble.  There is where the debate on many forums are - whether toroids produce better sonics.  But I won't go there. It's better efficency is a given.  Efficiency however does not necessarily equate to better sonics.   But that doesn't change the fact that toroids are more inherently efficient because of its geometry and construction.  The sites I referred to are very clear on that.  Better still, just pick any engineering textbook about transformers and the same conclusions can be found.

The debatable issue is on whether toroids provide better sonics. Those debates are everywhere in many forums I've visited and joined.  But not about efficiency.  That's already a given.  Efficiency in transformer operation has nothing to do with accoustic qualities.    And you can be efficient in providing lousy quality.   ;D  But there are also pundits who would argue that toroids have performance qualities outside of efficiency that improves on the sound quality. I would go for that as well.  But that's another topic.

It means your tranny has two 25V windings. it's the same as saying 0-25V, 0-25V. the output is fixed at 25V, not from 0 to 25V.

True, but I guess given the choice, many DIYers would go for EI.  There's no question that both toroid and EI can do the job.  But the expense and trouble going for toroid may not be necessary as efficiency is not exactly a priority in many DIY projects.  If it is, no DIYer would bother making class A amps, - the most inefficient amp circuit topology there is.   ;D  Ofcourse like anything else, there are exceptions.

In fact, this is the whole crux of that 'efficiency' he is talking about - Do those many pasting he made  ;D  ;D amounted to significant SUPERIOR efficiencies of a torroidal transformer? Are the challenges posed to EI against the torroid hard to come by - and expensive at that? You are correct, magnetic losses maybe hard to compute, but you can basically lump sum its total effects as LOSS (in power), thus you have the equation to compute for efficiency (if power is the one we are talking about here).

If he is merely talking about efficiency by ways of space and materials used - I will crown him the winner of this discussion  :D. And will agree with him.

But, is it all that there is in all your transformer requirements for torroids to merit SUPERIOR efficiency - as Tony said - basically a general statement that is void of substance.

and does this mean torroid has no misgivings in anything that it does not need compensation on its own inefficiencies or challenges?

Post by: rascal101 on Sep 07, 2006 at 12:28 PM
On a typical switching PSU ...

On the computation for losses in a typical switching PSU on the DC-DC FETs, most of these losses come during turn-off losses. This is the state when the DC-DC FET (MOSFET) is off hence the Vds is ramping to the bulk voltage level and the current stored on the DC-DC transformer is ramping down. If put a voltage probe at the drain and source of the MOSFET and a current probe at the drain. The Vds waveform and Id waveform when put side by side forms an intersection. The area formed by this intersection is called the turn-off loss. This accounts to about 70-80% of the losses on the DC-DC FETs which are significant contributors to efficiency loss.

With higher inductance play because of higher permeabilities Vds tends to be higher and the slope or the ramp  also proportionately becomes higher as well as the transformer or drain current. This will cause the area formed by the intersection of Vds and Id to be higher which results to higher losses ergo a decrease in efficiency.

The problem with EI is that since if has lower permeability and you need more turns. Also the relative size of the EI compared to torroids is larger. So in EI you will tend to have problems with thermals and high DCR (DC resistance).

Try winding a toroid and try winding an EI. Paikot ikot lang naman EI unlike toroid up and under. You say easier kasi you seldom exceed 2 layers per core whereas on EI you have several layers. However, using a winding machine speeds up the process.

I remember my uncle working in the US base called a technician to check whats wrong with his sansui amp before. After checking, the tech said, 'a certain resistor should be taken away and it will work' - tech as he is, my uncle said - nandyan na yan nong OK tumunog amp ko, tapos tatanggalin mo?  ;D  ;D  ;D  Na-Magic?

With these guys made aware of the internet pricing, they thought they can follow same pricing scheme. this is why sometimes, I would rather get a dusty unit that is working, and clean it myself - because with this, I can be a little more confident, everything is untouched from the inside - but of course, who knows?

Try winding a toroid and try winding an EI. Paikot ikot lang naman EI unlike toroid up and under. You say easier kasi you seldom exceed 2 layers per core whereas on EI you have several layers. However, using a winding machine speeds up the process.

That's the common observation.  Both by professionals and amatuers,  Toroids are difficult to wind.  And that is what makes it more expensive, not the core material.   I really suggest people try it one of these days to see how "easy" it is even with just one layer over a doughnut ferrite core.  ;D   But there are actually some techniques I heard that make it easy,  just can't recall those.

True, but I guess given the choice, many DIYers would go for EI.  There's no question that both toroid and EI can do the job.  But the expense and trouble going for toroid may not be necessary as efficiency is not exactly a priority in many DIY projects.  If it is, no DIYer would bother making class A amps, - the most inefficient amp circuit topology there is.   ;D  Ofcourse like anything else, there are exceptions. 

I would agree but in my case on the Class A F1 by Nelson Pass, we are using a torroid just because the owner of the project wants to build it as close as the original F1.

Of course efficiency in a project amp's psu is always a criteria, but this can be readily solved by using the largest EI or torroid tranny one can find that would fit the casing so max loading of the tranny is surely avoided. But then again, efficiency in power amps can very well be sacrificed almost immediately when the question of sonics is raised.

I think this debate on efficiency of EI vs torroid should be laid to rest since most psu designs involving EI and torroid trannies are overrated. Well at least to the DIY'er that is, say we need a max of 300VA, most DIY'ers use 600VA or even higher, talk about efficiency.  ;D

There's really no debate at all as far as performance efficiency is concerned. The toroid wins hands down.  But like I said efficiency has nothing to do with sonic qualities.   The debate that I almost always encounter in many forums is on the claim  that toroids impart better sonic qualities.  That's where arguments from either side start to fly.  And while I am on the camp that agrees with such a claim, I have no inclination to go into it.   

And yes, in this hobby, it's always better to err on the side of plently.  In my DIY years, I also would use over-rated transformers, electing to get a 1kva tranny when the specs required only 750va or thereabouts.   Most of the time, I just get ready-made trannies from Raon and in the absence of a VA value I needed, I go for the next higher one.   ;D  And they were all EIs, though I would have loved getting a toroid if it were locally available at that time. 

But in the area of production for business and commercie, that's not very prudent.  You always talk about optimizing and  getting just the right material quantity and quality for the job.  Toroids fulfill not only a technical need but it dovetails nicely where efficiencies of operation are required.

It is determined by

1.  How much hold-up time you require - meaning to say when you turn-off the appliance, how long before the PSU can supply regulated voltage to the circuits

2. How much current is required by the circuits (I = C x dV/dt)

Title: Re: Surplus amps

C = (Ilc/dV) x k x 1,000

C = capacitance in uF
Ilc = load current
dV = peak-to-peak ripple voltage
k = is "6" for 120Hz or "7" for 100Hz (use "6" since Philippines has 60Hz line frequency)

when voltage levels of the succeeding stage prevents direct coupling, then you use them, or when you are uncertein of what dc voltage your input will see, you better use them.

when more ac gain is required, then you bypass emitter resistors with caps, when you want to roll-off certein frequencies and shape the frequency response of your amp, then you use them.

on dc rectifiers, capacitors are a must, lowers the ripple voltage to almost nil...

the values are determined by certein considerations as voltage levels, ripple requirement and frequency cornering.. ;D

and i end with a note, the best coupling capacitor is no capacitor.... ;D

asfaik, they have no relevance to amps in genral, they are relevant to switching psu's as the main filter caps ought to have a certein hold-up time to maintain their charge under load, or hold up time for the output voltage to stabilise before a "power good signal" is asserted.

yup, it is really hard if you do it by hand, but nowadays, there are "machines" that can wind them quickly and in a mass production type runs just like EI's.....mass production lowers the costs, so that the torroids being more expensive than EI's can easily be a myth also...

If you have very little (almost nil) ripple voltage, you will have very little input current going to to main circuits. This is because it is only when the input ac voltage is higher than your bulk voltage is the rectifiers conducting. With very little input current, you will have lower efficiency. So their is a trade-off between ripple voltage and efficiency.

no, there are other reasons why you want to regulate, and psu ripple is just one of them. tubes and transistors will most likely change their operating points with a change in supply voltage, is this bad? not nescessarily, but a change in operating point can contribute to distortions otherwise avoided when rails are held constant.

Greetings,

I found this in a surplus shop. Bought it for 1.5k after making some tawad from 1.8k.

SONY TA-5650 VFET

Here :

Not, the actual pics but exactly the same even inside.

(http://img392.imageshack.us/img392/685/img02kq9.jpg)

Power up lang no testing at 100V. I knew I was taking a big risk but since I was not able to go to Nadb for his cheap stuff.  :-[  :-[  Eto nalang kinursunada ko. Power button lights up green. Knobs were easy to remove so I was able to clean the face very well. A few edge scratches and bumps at yung top cover meron dent yung isang grille element but otherwise ok naman. Cleaned the insides - well mosty the transformer and the power board with twin fuses was all that needed the dusting. No wood sidings as some units had. Good thing there was no scratchy sound in any of the knob controls or switches.

Used the amp over the weekend and no problems naman and in fact malakas as I never had to go over 10 o'clock sa volume as it was loud enough na for me.  ;D Checked DC offset voltages and came out with the following: Left Channel : 24-28 mV. Right Channel: 7-9mV.  :D  :)  :)

Read somewhere that these amp should run hot. However this one ran pretty cool naman even touching its twin "chimneys" inside. Well, warm yung fins ng heat sink and I suppose that's normal.

Tested the AUX inputs using my CD player and the tape inputs I also tested and they were OK. Next weekend try ko yung phono stage. Cheerio.

Sirs,

Meron nga pala akong nakita na Sansui AU-555. Pina buksan ko para tignan, malinis naman. Kaya lang pag power on, after a while, me pumutok malapit sa mga power caps. Wala namang usok, at parang buo pa naman yung mga capacitor, pinatay, tapos pag on ulit, parang nag hu hum (walang speakers na naka kabit pero yung body ng amp eh nag reresonate at parang nag huhum ng mababa - baho ika nga) , tapos pinatay, pag on ulit di na umilaw power lamp dahil pag tingin namin bumigay na pala yung fuse. Tried substitute, ganon din. What could possibly be wrong with the unit?

Sigurado naman pwede ko makuha ito ng malamang less than 500 o baka libre na. Kaya lang baka super gastos naman pag inayos ko.

Humming even without speakers connected?   Have never encountered this though I've read about transformers making humming noise due to their core construction failure or what they call lamination rattle that literally causes the transformer core to vibrate.  Yung umusok could be the lamination burning, just guessing though.  A short may have developed in the windings to deliver voltage or current outside the rail fuse tolerance.  Maybe changing the power transformer is all that is needed.

Funny thing pricing surplus amps, mas mahal pa nga itong sansui kaysa don sa sony na vfet kc black face. Kahit mas mataas power rating noong sony.



Sir Rascal,

Okay yung Sony na vfet maganda pala tumunog ito. Surprisingly, kahit di gaano ka taas power rating niya, eh, kayang bumira ng mataas na volume. Parang di gaano nagamit kc pati yung mga RCA jacks sa likod, kahit inalis ko na yung oxidation, mahigpit parin, birhen pa  ::) ::) ika nga.  ;D  ;D  ;D

Ang parang minus lang eh, yung balance knob, hindi auto centering. ???  Yung base at treble ay step switch type eh so no problem. Ang maganda naman, meron siyang memory setting para sa volume. So pag meron kang preferred volume setting, e pwede mong  i set yung mechanism doon, and every time you move the volume knob, it kinda snaps to that position.

Di ko pa nasubukan patugtugan ng plaka. Try ko sa sabado.

Fuse will alway blow because the fault that caused it hasn't been corrected.    I don't know about Fil-Audio, but since it has a schematic, any veteran techie should be able to diagnose and repair it properly.

Thanks for the info sir Sandawa, Meron kaibahan ang tunog niya as against my Sansui's and my other Sony.  Parang airy na masarap naman pakinggan. Will do what you suggest sir sa Vintage Knob at aalagaan ko to. Again thanks.

I'm an SS guy who likes dynamic and loud music, not very fond of tube sound. But I also want to hear valve gear sometimes (I still have two tube amps, thus I could compare) and the VFET is an option. My impression is that it sounds distinct, comparatively thinner -- medyo manipis tumunog, approximating valve's "sweetness", which some describe as "coloration." Almost all VFET users in Audio Karma have the same observation, by the way.

I have received offers from AK members wanting to buy my VFET power amp, as high as $500 (freight charges on them), and I was almost tempted early this year to say yes. However, I found the proper match to it a few months back: An Onkyo p306 preamp and a pair of Denon SC-104 vintage speakers. Very nice sounding combination.

Hi guys.  Just stumbled onto this thread.  Can I get directions/tips/hints on how to go to these surplus shops?  I'm interested in these old-skool amps, and more recently old-skool speakers.  I was listening to my father in law's old-skool JBL studio monitors, and I was wondering if these shops carry those old JBL/Boston monitors (the three-way ones).

If I can find those monitors, I might just sell my Diamond 9.1 set and stands. . .

Thanks in advance!

tanong lang po ng isang baguhan,

still have a kenwood amp from mid 80's or try to score a surplus amp.
ma incorporate ko ba to if am trying to set up is 5.1/6.1 HT?
kase di ba dami channels para sa 5.1/6. i
gnoramus pa lang po.
tnx

HT amps of the late 80s are PRO-LOGIC amps that just simulate 4 channels into 4 amps (except for some flagship models that have 5 separate amps) - Left, Right, Center and Surround which makes use of two speaker connections.  You won't be able to enjoy the discrete 5 channels of DVD sources, but you can still play them in stereo mode and then swtiching the receiver to prologic mode to simulate 4 channels.

pioneer a-uk3 is either the jap version of the a-400 or a-400x, whatever, oks lang ;D

btw, its got 2 sets of speaker terminals marked for biwiring - the top set-HF, the lower set-LF.

got it for 2.1k pero sira yung power button (always ON) no big deal.

worth the long wait, early 90s nakita ko a400 & a400x dito sa pioneer raon showroom, selling for 9k yata. i had the nad304 that time so pinalampas ko along with the 300R precision. nabasa ko din during that time yung rave reviews ng a400 and the mixed reactions to the a400x. sana may maligaw na nad3020 at audiolab 8000 ;D

sandawa,

medyo nalilito ako sa a-uk3 / a-uk3ii & a-400 / a400x

sa pictures dito =>kamuka ng a-400x ang a-uk3  ko
http://www.hifigoteborg.se/photo%20arkiv%20amplifiers/photo%20arkiv%20amplifiers/PIONEER_A_400X_detail.htm
http://www.hifigoteborg.se/photo%20arkiv%20amplifiers/photo%20arkiv%20amplifiers/PIONEER_A_400X_BAK_detail.htm

if the a-uk3 = a400x, & a-uk3ii = a400 it seems the pairing isnt quite matched. usually mark2 versions come after the orig. in this case i assume a-uk3 is the orig and a-uk3ii is the succeeding version. since the a-400 was released before the a-400x so it should correspond to the a-uk3, rite?

dito=>30wpc/8ohms ang a-uk3, di ba a-400 & a-400x around 50wpc?
http://www11.plala.or.jp/teikakakucosme/PIONEER-EXCLUSIVE/amp/a-uk3.html


nalito din si parasmi kasi iba daw yata yung nakita nya a-uk3ii may isang set ng speaker terminals. so mukang dalawang units ang lumabas, at may isa pang sinuerte sa pier

anyway, bottomline, im enjoying the a-uk3 now. simple and straight just like the minimalist MF & other bloody effing limey amps of yore ;D
cheers!
Title: Re: Surplus amps
Post by: sandawa on Feb 18, 2007 at 02:23 PM
Ako rin nalilito since the UK3II looks the same and different to both the A400 and A400X. And it's also rare, you don't find it in most Jap hifi directories, kahit sa auction market. My hunch is that after the a400X, the Japs went back to a simple A400-based amp that was never sold in UK. That amp became the limited edition UK3II with "Simple and Straight" circuitry. The headphone jack and the bi-wire speaker terminals were removed. If you look at the front panel and the innards, nothing much changed, however.

By the way the domestic version of the A400 or A400X (A-UK3) didn't sell well in Japan as per auction records, roughly 10,000 yen used. I think that reflects the difference in sonic preference of whites and oriental ears and their listening environments. They use heavy bricks in cold and quiet UK homes, while we use lighter materials in our warm and, sometimes, noisy rooms due to airconditioners. That makes a significant difference in my opinion.

Here again is my unit:

sandawa,

only diffs b/w a-uk3 and a-uk3ii are

1)"simple and straight" on the front panel
2) "wide range linear circuit" vs. "stereo integrated amplifier"  on the front panel
3) 2 sets vs. 1 set  of speaker terminals

time to enjoy this baby and just leave it at that- whatever intl. model our jap amps correspond to it still sounds the way we expected it - clean and clear with lots of punch ;D

From my previous reading ... due to high real estate cost in Japan ... Japanese do not typically have big homes (like ours or in UK) ... so majority of them are typically near-field listeners ... so choices in Japan have this listening mode in consideration is standard purchases!

Thanks. I don't think space constraint was the reason why the A400 series wasn't a hit in Japan. This model sounds good on small space listening environment, so it was more on oriental ears' preference, I think. But true, the buying preference for a big segment of the Jap market is biased in favor of smaller, not necessarily inferior, gear.

I've made an A/B comparisons of A-10IV (60wpc @ 8 ohms) and A-UK3II (60wpc @ 4 ohms) using same pairs of speakers and on several speakers. It was no match. The A-10 was so smooth and with tighter bass from 1 watt up.

Rene,

The AU-7700 was the one I was asking you to buy for me from the Pier two years ago after I got the Sansui AU-70. The price, if I remember correctly, was also about that range.

nani,

di ko tinest, kilatis yung au700 coz #1-wala budget dala, auk3 talaga pinunta ko pier. in fact, i was in touch with parasmi, told him na na-attract ako sa au7700 while the seller was setting up the auk3 for demo. hehehe muntik na malihis ang bili but reason #2- kararating pa lang daw nung au7700 maluwag yung upperleft knob (selector) at may cracking sound pa for minor repair daw so i passed.

Hi Sirs,

I got this Pioneer SA 8800 II (pre-mains) at the pier, I will appreciate it very much if anyone can share their knowledge about this amp. In silver Pioneer site only the SA 8500 II was mentioned although I think both amp seems to be the same in appearance.
I got it for 3.5K. The sound for me was very good and I like the turn over feature (similar to a cross over) at the tone controls, I returned it after a month because of a popping sound on the right chanel and now its again working perfectly fine. I hooked it up in the main-ins of my Accuphase and was able to drive a 360 watter kenwood vintage speakers easily during a party in our office.

Sir Dana,

Thank you and I will do as you suggested. They say that this amp was used by many as a mobile amp. Is this amp a monoblock type because both channels are powered by separate transformers? Wala po bang problema if I use A+B speakers? Ilan po impedance ng mga speakers mo?

 Talk about  a faceplate na tinubuan ng madaming aluminum knobs or the reverse....Yup, monoblock type inside. Separate power supply for the left and the right (nice engineering symmetry arrangement inside....)
The speakers are 6 ohms nominal , i think. Im more of a moderate level listener.Havent tried yet "putting maximum pressure on this old locomotive"(borrowed quote from an AKarma member...), but you can try ;D.

Sir Dana,

Salamat uli. If you are saying your speakers are 6 ohms nominal, di po ba pag nag A+B ka with all 4 speakers @ 6 ohms impedance magiging 3 ohms ang load ng amp? are you saying ok lang ito basta wag ko lang lalakasan masyado so as not to stress the amp?

Very tempting po kasi I set my other amp to drive 1 pair of diamond 8.3 and 8.1 at A+B din, very nice po ang result but my friend told me that I will stress the amp very much in doing so.

Thanks in advance.

Hi Sirs,

I got this Pioneer SA 8800 II (pre-mains) at the pier, I will appreciate it very much if anyone can share their knowledge about this amp. In silver Pioneer site only the SA 8500 II was mentioned although I think both amp seems to be the same in appearance...

It was conservatively rated at 60wpc, released in Japan in 1977. I own the older model, SA-8800, with only one transformer but sounds very good, I'd say better than new production amps. AK's Doc Strangelove who said he's heard from Filipino friends that Pioneer is a big audio brand here, has a Jap brochure with SA-8800II's specs:

I got it for 3.5K. The sound for me was very good and I like the turn over feature (similar to a cross over) at the tone controls, I returned it after a month because of a popping sound on the right chanel and now its again working perfectly fine. I hooked it up in the main-ins of my Accuphase and was able to drive a 360 watter kenwood vintage speakers easily during a party in our office.

Been used to this current set-up of mine for a long time na  ;D. This amp, i think can tolerate 4ohms as recommended. Theoretically, i think your correct but speaker impedance is not a fixed value, it varies with frequency. Also, the amp has a built in relay protection circuit that will shut off automatically once it detects 'anomaly'.Medyo nasa wild side nga ng konti but just what I said, evertything in moderation.

thanks

Sir Joey,

TY. Yes indeed it has kick ass sound but for this setup bitin ako as I am only using old mini compo speakers. Although the speakers will be my next project.

Sir Dana,

TY and Very nice setup! Hopefully on my next visit to our favorite mall may mapili na akong speakers. Nangangati na po tuloy ulit ako pumunta sa pier.....

I also own one (SA-8800) ... nice materials (thick faceplate, solid aluminum knobs, hefty black heatsink with nice type TO-3 heatsink mounter) ... but got it with amp stage transistor in disarray already ... I fitted it with regulated LM3886 driven by SA-8800 pre-amp  8) ... still very productive and beautiful as ever

These surplus amps can stand on their own just as they were designed to do, there is really no need for external pre-amps as it will just add to a longer signal path. But then if they have this "power amp main input" and "pre-amp output" jacks, then you may try other preamps, just disconnect the amp's preamp and connect an outboard one.

you may try another amps' pre-amp out or if you have a tube pre-amp like the Tono, then you may try it.

I am trying to audition various pre-amps, now specifically for tubes.  I also wanted to hear a SS pre-amp and what would be the sound effect in my tube power amp.  I am now finding out that some tube pre-amps lacks the "presence" factor over others when hooked over my tube power amp.  Im trying to find the best combination.  All combos possible and no bias over any equipment so as to make it a fair game.

Bro got a 1974 Onkyo Integra A-755 MK2 for 2k a few weeks ago. another wiredstate member (TA-F333ESG) had the same amp driving
his b&w 602 S2 using rotel cdp as transport. mine driving a kefq1 and nad cdp. true vintage amps can outclass most entry level avrs. I had the pleasure of owning a denon 1604, harman kardon 2550, rotel rsx 965, yamaha dsp a1 and this vintage amp outlass both denon and harman in 2 channel. pretty much close to the rotel in terms of dynamics.

Last weekend I hooked a trod musika pre-amp in this baby and boy it was nirvana  ;D.

if I were to get a SS amp, it would be at the pier and not in any audio shop having prices more than 20k.

However, a good dedicated pre-amp is what I am looking for, mapa tube or ss.

I can not justify using a pre-amp 7X the cost of my surplus amp  :'( If you can find a good surplus dedicated pre-amp then that's more justifiable in terms of cost.

Maybe the surplus guru's here can recommend a good dedicated pre-amp found in pier

If you were based in Davao, you could easily audition several good vintage preamps that are available here. On a good day, you can get classic SS preamp models as low as P1.5K. Normally, price ranges from P2.5K to P3.5K per unit for good vintage preamps. Here are links to two units that are available from a surplus dealer here:

Also available is Yamaha M-50 power amp, again overpriced at P7K, considering it's an international model (240v) not a Japan 100v premium unit.

We still have minidiscs here in Davao, I think. Two years ago I was buying sealed minidiscs at only P80 each. Last time I bought last year, the remaining shops that sell it quoted P120 each. I don't know how much it is now but I'm sure we still have a few dozens in local shops.

Thanks sir. Before I bought the unit, I asked the seller to remove the cover kasi hindi kita ung loob. I wanted to make sure na wala pang repair. Nung mabuksan, even the seller was amazed at the toroid, hindi nya alam na ganun. Kaya nung tumatawad na ako, hindi na pumayag  ;D

Toroid transformer narin at not surplus (120/220/240v adjustable). Early 90's model ata ito. Very few reviews I see sa web, kaya ask ko lang to the afficionados here, what they think of this amp.

Denon was a pioneer in PCM digital technologies and earned its reputation more from the recording industry under the Nippon Columbia brand.  It also got famous for its turntables and digital players.  I recall having a number Denon classical CD discs in the mid to late 80s.  My second CD player in 1989 was a Denon.  And Denon turntables were one of my dreams in the early 80s.

Thanks. Actually, I compared this with a NAD 320bee. The Denon's Mid is more open and the highs more detailed. Dynamics is good yet not fatiguing. It was able to drive my Celestion SL6si (86dB). I think this amp is underrated at 60watts/ch. Understandably, natalo lang siya dun sa Denon PMA890DG ko  ;D which is newer and more powerful at 110w/ch at 8ohms, w/c also has built-in DAC (Burr-brown pa :D)

(http://www.marantz.jp/bc/brand/images/photo/03/pm4.jpg)

specs:

2x60w AB or 2x15w class A

here are some pictures from the net:

(http://www.thevintageknob.org/ESOTEC/Eown/eown-urban2)

the marantz esotec pm-4 i got is a non-surplus amp. i posted it here so in case you find one in Pier, i suggest you better grab it.

thanks for viewing.

Reymer, Yan pala ung Denon na binibida sakin ni Nonoy ha!!
Actually, nagulat din ako sa performance ng vintage Denon. May na swap akong PMA-510 recently (my first vintage denon too!), its a mid model and nothing much too look at but nung sinalang ko na ... oh my yayay !!  :o IMHO maraming tatalunin itong small integrated amp na ito sa mga new entry level amp in the 50 to 80watts category.

Sabi kasi ni Nonoy, silver face daw na vintage yun narinig nya na Denon mo.

Pre, wala bang kapatid yan!!  ::)

San mo naman nabingwit yan??? Luks very delicious ha!!

By the way, kindly txt me at 09219691109, iba na yata no. mo. Trying to text you wala kang reply. Tnx

Right now, I'm using a Denon PMA - 780D. Super satisfied ako. It actually has too much power to drive my Mission M72. My bookshelf speakers sound like floorstanders because of the tremendous amount of bass my speakers produce because of the amp. Night and day difference when compared to my Denon 1905 receiver.

Hello all,

I am a new one, just found and so interesting with this forum.

So, does any one have the manual or experience of the Japanese Amplifier TRIO KA-7100D. I got from my brother, but I got less the experience about this Amp.

Please advise me what kind of loudspeakers (B&W, JBL, JAMO available in my country) would be best for the AM amp.

Thank you so much in advance.

Thank you very much rascal101, but I could not get any technical information for my amp.

Due to choose the surround speakers for it, so if you don't mind please advise me the type of speakers which suitable with my AM amp. (especially: B&W, JBL, JAMO or BOSE...)

Best if you can bring your amp to shop for actual demo on a type of speakers you choose.

Difficult for me to judge your amp because I've only heard a Trio KA-7004 amp. To me this amp sounded "bright". Although I can be wrong (only used 1 type of speaker). For this case I would choose a dull speaker. Unfortunately for me (since I do not buy nor listen too much on brand new speakers) I could not suggest except for a Wharfedale 9.1 bookshelf speaker.

I've searched for your amp too but could not find anything on the web.

Good luck auditioning speakers.

A, B 4-16 ohms - If you will connect only 1 pair of speakers, the speaker impedance allowed is 4-16 ohms
A+B 8-16 ohms - If you will connect and use 2 pairs of speakers (both A & B), the speaker impedance should be 8-16 ohms, otherwise, you will overload you amp.

Thanks Reymer, one more question, the amp shown only input power: 100V AC 50/60Hz 150W. How can we define or calculate or estimate the output power for speakers will be engaged to. (Speaker impedance as my previous question)

If you know the idle current power consumed, you can subtract that from the input power and multiply the remainder by 60% which is the typical efficiency of most class A/B amps.  Then divide the result by the number of channels, you'd get some idea of the maximum power each channel can generate. 

So for a 150watt electrical input needed, I'd assume an idle current of around 20 watts, so you have 130watts multipled by 60% = 78watts.  Divide that into 2 channels, so you have 39watts RMS/ch.

I typically use 20~25% power used by the amp ancilliaries ... thus, 75~80% is audio power ... so for 150W, this may mean about 56~60W per ch ... almost the same with qguy

100V AC 50/60Hz 150W.

You will find this at the back of many japanese amps, notice also, that there are convinience outlets at the back of the amp, sometimes, they will be labled as "switched" and/or sometimes, "unswitched", ever noticed them? Some amps can have as many as three of those.

So now, what the power ratings means is that you can only plug in other appliances at the back of the amp not exceeding the power of 150 watts, so at 150 and 100volts, this is 1.5 amperes, not much i would say.

Now, for the power rating of the amps inside the box, we have to look at the rails used, look at the filter caps and it will give you a clue,  most listening is done at 2 to 5 watt levels anyway, so this is still plenty. ;D

Hi,

I do not know how to calculate but I guess the voltage of the power suply also giver a clue to the wattage.
And with older models you can search for the datacheets of the power transistors by their number on the internet.

Leo.
Title: Re: Surplus amps
Post by: ATJr. on Apr 29, 2007 at 09:26 AM
yes, power transistors used gives you an idea of how robust or how fast the amp is.
most amps will have filter caps in pairs, like for example, 50volt caps can be good up to 100 watts at 4ohms, a 75 volt cap, 200 at 4 ohms and so forth, 8 ohm ratings in these cases will be lower by about 50%....
Title: Re: Surplus amps
Post by: Lord Foo on Apr 29, 2007 at 10:28 AM
Don't forget that the step down transformer also limits the wattage of the units you can plug into the back of the source amp.

There are local transformers rated at 400 watts though i doubt that it can really handle 400 watts. I normally give an allowance. I suggest that it is worth the extra dough to get the higher wattage transformers rather than the cheaper wattage ones. The extra oulets will also  be very useful.

Likewise, remember that Jap amps are 100 volts, not 110 volts. I've had problems with Sansui amps using the black 110 watt transformers. I switched to the red 100 watt amps and I didn't have any more problems.

If you have a friend here in Davao, ask him to check Try-Us shop on Claveria St. between Bonifacio and Bolton Sts. The unit is cosmetically okay, but I never tested it. The shop has no landline number and the manager who has a cellphone was out when I went there a few minutes ago. The price quote is quite okay, significantly lower than its current quote in used hifi auctions in Japan, which is roughly equivalent to $100. But I'm not surprised with the price considering A-717 is in the same class as Sony's TA-F333ES and Sansui's AU-607.

Post by: markmlists on May 07, 2007 at 05:28 PM
In searching for surplus amp info on the net, I found confusing information about an amp being " Dual Mono"

In some readings "Dual Mono" means 2 transformers and in some, having 1 big transformer as long as there are separate windings for left and right channels is also considered as dual mono.

Denon PMA-850 and PMA-830 is said to be dual Mono despite having 1 big transformer.

Author/Reviewer said it here:

 http://www.hi-fiworld.co.uk/hfw/oldeworldehtml/denonpma850.html

Sansui AU-9500 is also said to be dual mono from their 1973 official brochure with only one transformer.

Copy of the original brochure here:

http://www.classicsansui.net/Integrated%20Amplifiers.htm


VERSUS

Pioneer SA-8800II A-717 Dual transformers- naturally dual mono.

So, does this mean an amp does not need to have 2 transformers to be considered dual mono?

Your thoughts please.
Title: Re: Surplus amps
Post by: rascal101 on May 07, 2007 at 05:42 PM
Dual mono means 2 separate transformers. One each for the Left and Right channel.

Brochures are are not necessarily 100% true. I believe this things come with the disclaimer "specifications subject to change without prior notice" - which is similar to "engineering reserves the right to change things depending on customer feedback or management feedback". Sometimes, the upper guys want to make a pitch - an upgrade or downgrade depending upon their mood. I think the brochure came out first before engineering made the changes.
Title: Re: Surplus amps
Post by: Reymer on May 07, 2007 at 05:44 PM
I think Dual Mono refers to amps with 2 identical, separate circuit modules for the left and right channels. I once had a NAD 214 Power amp and it is also described in HiFi Choice as Dual Mono, and it only has 1 big toroidal transformer in the middle.

Bro, ive seen many amps na ganito ang construction, only 1 big power transformer for 2 channels. (even an Aragon 4004 :(). Maybe this is the reason why some (those with deep pockets  :D) opt for monoblocks.

by your leave sir Reymer. the aragon 4004 has two separate, identical transformer. maybe you were referring to the 2004. lifted from "Classic Aragon
amps - A Primer"
"The first Aragon amplifier products were the 4004, and it's little brother the 2004.  The 4004/2004's electrical design was widely reported to be the work of Dan D'Agostino of Krell.  Mr. D'Agostino was credited in various magazines as being responsible for 1) Circuit design of the early Aragon components; 2) Parts selection; and 3) Development of the Quality Assurance program for Mondial Designs.  This may--or may not--be true, but it is NOT confirmed by Mondial or Klipsch.  The Industrial Design (the way the product looks, and to some extent, the internal parts layout) is the work of Robbii Wessen, as evidenced by the name "Robbii" silkscreened on the back panels.  Robbii performed the industrial design for the Aragon and Acurus product line up until the Klipsch takeover.  The 4004 and 2004 share chassis and general layout--the front panels are a flat plate, and the top and sides are formed from a single sheet of steel, perforated over the internal heat sinks which are below the famous "V" notch on the top.  The 2004 uses fewer output transistors, and a single, dual-wound transformer while the 4004 has two transformers.   The 4004 was named because it could output 400 watts into a 4-ohm load, thus 400-4 which became 4004.  The 2004 is rated at exactly half the output of the 4004, 100 watts into 8 ohms, 200 into 4 ohms.  Don't be fooled, the power supply of either amp is quite huge in relation to it's rated output.  The output transistors are individually tested and matched.  There are 8 output transistors per channel on the 4004, four for the positive side of the waveform, and four for the negative side.  Each group of four transistors will be matched.  Same goes for the 2004, except half as many transistors are used.  The output transistors are metal case units"

Separate windings for each channel pero using on the same core = dual mono???

Wala akong magagawa kung iyun ang definition nila. Ngayon kung maraming ganito ginagawa then accepted siguro ng industry. Ang tanong, ilang pa bang kumpanya ganito ginagawa?

Strictly speaking dual mono means separate power trannies, power supplies and separate circuits.  The only thing common is the power switch and the chassis and the power chord.  The Aragon 4004 pictured above can claim true dual mono classification.  I think this is what makes the Aragon more expensive than the Acurus line, among other things ofcourse.  I am not aware of any dual mono Acurus stereo amp, at least the newer ones before the Klipsch takeover. 

But I guess in the interest of saving space, you can have separate transformer windings sharing the same core instead and still claim dual mono. 
Title: Re: Surplus amps
Post by: rascal101 on May 09, 2007 at 11:27 AM
Definitely there will be 2 separate layers for left and right channel. The one closest to the core will definitely have lower parasitics.

If it was me, I'd rather have one winding for mains supply which I believe most manufacturers opt. You can use the available space for auxiliary supply. Why bother with 2 separate windings - 1 ea for left and right channel. Thermals will definitely be higher + additional process and cost.

Yes,Edrel makes them. He can even make you a transformer with 100 & 110 volts output with built in primary switch (fuse protected), which makes it more convenient.

conservatively rated at 30 to 35wpc; early '70s, thus, beware of capacitor problems; i have an L-505V from that series that sounds different from my other Luxmans and SS gear; tends to mimic my Sansui AU-70 (valve) which came out in mid-60s.

Sorry Mel ngayon ko lang nakita 'to :(  Been busy with other stuff...(check my signature) ;D
Anyway, I don't think I'm qualified to do a review.  I've owned only three stereo amps including this jewel and I've never done any so called "critical listening" (di ko ata alam pano un?) so I don't have that much experience.  Mahirap na magsalita.  Bottom line is I like it.  My cd player is at least ten years old, my speakers are older; they've never sounded better than now that I'm using the Sansui with them.  Is it for sale?  Not at any price ;D

Muntik na ako magkaroon nyan, but I chose the AU-9500.
http://www.classicsansui.net/Integrated%20Amplifiers.htm

I was ignorant at that time (until now, medyo less na lang ;D). Besides, the AU-X1 i saw doesnt have nice faceplate prints (burado mga prints because the tindero used wipeout,,,beware of using this, use only the MC brand, mas mild yan).Cgurado, pag may naligaw ulit nyan sa harap ko na ok sa alright (price and condition), wala ng kawala yan ;D.

Anyway, jackpot na rin pala ung AU-9500, black faced nice sounding SANSUI.

Critical Listening, pano nga ba yun ;D? If we take it seriously, baka unending SARS ang punta natin nyan.Just enjoy the gears & the music we like, my unsolicited advice.

i owned a repair shop in the late 80's up to 1994 before working as an OFW, 90% of the amps that went in to my shop were sansuis' that is why the term sansunog was coined by bert, also a shop owner in raon...at that time most of the units came from saudi, plastic sides, gray metal tops, lawanit bottoms, silver facia..

problem then was the prolifiration of fake replacement transistors, which burnt out as soon as we put them in.

bottom line, brand alone does not tell much about a product, there are products for the mass market at low prices, there are products for export, and then there are high-enders, top of the line.

except for the 100volt ac ratings, i would say amps from the pier belongs to the upper class of japanese manufacture...

finally let us not forget those owners, who for not knowing any better, punish and push their amps to the limits...they have the biggest hand in all this... ;D

I came across the AU-XII. It's really big amp. Its available for me to purchase in pier area before, the price: 7k. If I got good reports on its reliability, I could have bought that. But thanks to the internet, I know better (straight from the SANSUI service engineer). You should thank yourself, you didn't get one.
Title: Re: Surplus amps
Post by: rascal101 on Jun 26, 2007 at 04:53 PM
Thanks for the advice but for sentimental reasons I would still buy one even with some issues in reliability. Siguro naman as long as operated within specified conditions wala naman magiging problema. My understanding is the Sansui became notorious in this regard before because people were overloading it. If I recall, the total impedance of speakers used was less than what it was rated.

For the Sansui AU-D907F amp I have, if I use 6ohm speakers the amp trips when volume reaches 1:00 position. No such problem if I use 8ohm speakers. In the datasheet, this amp is rated for 8ohm speakers. Further, I also notice that the amp gets very hot. So it can be that issues with Sansui amps were because of poor ventilation and use of lower impedance speakers than what is rated.
Title: Re: Surplus amps
Post by: sandawa on Jun 26, 2007 at 06:01 PM
To generalize that the Sansui AU-XII has a reliability problem is wrong. I have been using one in my living room for four years now and no problem whatsoever. I have a friend here in Davao who got his AU-XII two years ago and he also has no problem. Only a couple of modified units of AU-X1 distributed in US and Europe were claimed to have problems -- as per previous discussions in Audio Karma and Audio Asylum. No literature from Japan said AU-X1, or AUXII, has instability problems. AU-XII was only sold in Japan, 100 volts, no such model came out in US or Europe.

BTW, my latest noteworthy acquisition here in Davao is a Luxman L-550X (the replacement model was L-570) -- Class A, 50wpc. Very very hot and sounds so good -- only the Sansui Alpha 907i-Mos Ltd could beat it. It's certainly better than the AU-XII, Accuphase E-302 and NEC-A10 IV. Brand new price in early '80s was 269,000 yen, current resale at about 70,000 yen, about the same figure as Alpha 907i-Mos Ltd.

If you find a good luxman nowadays, grab it, nothing in its class beat the sound of luxman, in my own opinion of course. My set up is luxman L510 x for ampli, tono pre amp, arcam cd73T cd player and a spendor S3/5 for speakers. Its a very good combination and I have not upgraded for the last 3 years and maybe forthe next 5-10 years. ;D

I was just using a Luxman m120a and a Sony VFET TA5650 the past weeks with a Yamaha NS1000m.
I still love the Luxman M120a... but somehow, with the the Yamaha monitor...the VFET (just recently replaced with new crystal diodes and the bias adjustted) is a more astounding amplifier. I can't bring myself yet to reconnect the Luxman m120a to recheck my comparison with the VFET.

congrats then, it survive those years!

I may not experience it first hand ... but the analysis is grim ... not because it has bad design flaws ... but in fact, it is too fast an amplifier ... too fast for its own disadvantage ... ready to oscillate at small signal anomaly ... but rascal have good reason ... indeed a work of art to brag about ... unusual size, seldom you can see, and the parts worthy to keep ... would rather have the 907MOS though ;D ... if you spot another, kindly alert me and will readily fly davao that very day  ;D Pier is not as exciting as before in terms of good heavyweight amps ... been there many times lately, and typically, is now a waste of time browsing the area.

Post by: Lord Foo on Jun 27, 2007 at 10:14 PM
Sir Rascal, thank you for your comment on my Ns1000m and VFET. I am quite contented with those two units.


You are right aHobbit, the last few times i've been to the Pier, I went home empty handed. This is the state of affairs Sir Sandawa forewarned as about. Japanese excess units are now probably now being shipped to China and India. In fact even at the pier, i've seen some Asian Sailors picking out the better units with their USD Cash on Hand.

About amps getting hot, people have been telling me that some of the amps i own really run hot normally. However, i've noticed that when i've been able to secure a service manual and my brod was able to set the bias , dc offset correctly, the amps starting running cool. IN fact even the sony VFET which was claimed by some guys at the AK to run normally hot, runs very cool now. I have even fallen asleep  with the amp running on a tuner and when I touched it in the morning... it was just very very slightly warm you can just slightly feel the warmth.

I was just using a Luxman m120a and a Sony VFET TA5650 the past weeks with a Yamaha NS1000m.
I still love the Luxman M120a... but somehow, with the the Yamaha monitor...the VFET (just recently replaced with new crystal diodes and the bias adjustted) is a more astounding amplifier. I can't bring myself yet to reconnect the Luxman m120a to recheck my comparison with the VFET.






sir lordfoo,

saan mo pina repair ang sony vfet? meron kasi akong pinsan na may sony ta-4650 vfet amp na binigay ng ermats nya galing US, nabili sa garage sale. matagal ko na tong inaawitan pero di ko pa nakuha dahil wala akong pampalit na amp sa kanya. di mahilig sa audio ang pinsan ko kaya wala siya pake sa vfet amp, lalo pa antique look na. ngayon di na raw gumagana, kaya bigay na nya sa akin nalang na walang kapalit ;D saan ko kaya to pagawa? i am based in ormoc at takot ako na ipagawa sa mga tech dito baka lalong maging junk. sana di ang vfet ang sira kasi obsolete part na daw to.

Sir Weng,

My Brother knows a bit about electronics. He didn't actually repair the Sony 5650. What he did was follow the Service Manual instructions (and reading on the net regarding the vfets0 on how to adjust the bias and dc offset setting of the amplifier which has strayed from the factory settings from the time the unit was produced. Then he replaced the diodes which AK gurus claim are the cause of permanent damage to the transistors. It is said that if the VFETs are gone, the amplifier is just a Huge Paperweight. He still has my 4650 which was already adjusted but still has problematic pre-amp section.

Actually, he didnt follow the advice of the AK gurus exactly who recommend a bias setting above 0. He set it to full 0 to totally avoid the heating problems.

By the way I have a soft copy of both 5650 and 4650 service manuals if you are interested. Your technicians will need these to work on the vfets. My brod couldnt do anything about the adjustment till he obtained a copy of the SM's.

Also, my brod mentioned that although the 5650 is more powerful than the 4650, he connected the power amp section to another pre-amp to bypass the problematic preamp of the vfet to test the unit.

He claims that the 4650 sounded as good as the 5650. It is thus a rare unit that deserves restoration.

Now as to whether he will accept non-brother projects, i still have to check with him.

I am based in Quezon City.

congrats then, it survive those years!

I may not experience it first hand ... but the analysis is grim ... not because it has bad design flaws ... but in fact, it is too fast an amplifier ... too fast for its own disadvantage ... ready to oscillate at small signal anomaly ... but rascal have good reason ... indeed a work of art to brag about ... unusual size, seldom you can see, and the parts worthy to keep ... would rather have the 907MOS though ;D ... if you spot another, kindly alert me and will readily fly davao that very day  ;D Pier is not as exciting as before in terms of good heavyweight amps ... been there many times lately, and typically, is now a waste of time browsing the area.

I was traveling a lot these past few months and was at the Pier (Manila) a week ago. True, no upscale amps or speakers there but a lot of units on the shelves of Chatty's and the two sidestreet stalls. You don't see that here in Davao. But at least we still have one or two good models arriving monthly like the TOTL Luxman 550X I got a few weeks ago. Just yesterday, a trader showed me a pair of original US-made ElectroVoice small professional monitors at a "discounted P9K", still a bit high for me. I already have a full-size EV Interface A anyway. But he got half a dozen pairs of those EV monitors from Japan last weekend and 5 pairs already sold in just a couple of days at P10K each.

There are still a few unsold but interesting mint units I saw here:
Victor A-X1000 http://www.niji.or.jp/home/k-nisi/a-x1000.htm
Pioneer A-900 http://www.niji.or.jp/home/k-nisi/a-900.html and
Sansui alpha 607XR http://www.audio-heritage.jp/SANSUI/amp/au-alpha607xr.html

The price I think is from P6K to P7K. If anyone is interested, I'll get the phone numbers of the shopowners. I don't want to be a third party -- I'm too busy for that.

aHobbit, for being a true and consistent hifi enthusiast, I'm taking your post seriously. I'm running out of space here in Davao and I would probably yield, just for you, on the next alpha 907 arrival here. Who knows? We could even get one of those rare items cheap. Or, if you want, I could buy it, then swap with your NEC a-10.

Post by: sandawa on Jun 28, 2007 at 12:26 PM
I think this was covered adequately by a Time magazine article last year, although I don't quite remember if it mentioned India at all. The best consumer electronics surplus from Japan now goes mostly to the port of Shanghai, which is as progressive as Hong Kong. Why? Because the Chinese who had a closed economy for decades never had the chance to listen to good hifi. They now have the money to buy the best surplus equipment they could find. BTW, even US and UK audiophiles never got to listen to those upscale gear we now enjoy -- courtesy of those surplus shops. I have been getting fantastic offers for some of my gear from buyers in UK, Germany and US. No deal.

Three years ago, traders here in Davao told me their contacts in Japan said they could sell good vintage Japanese hifi to Shanghai audiophiles at more than twice the price they could sell in RP or Vietnam. That means a Sansui AU-XII, which i got P8K four years ago, could be sold at least P16K in Shanghai. That's closer to used AU-XII's price in Tokyo or roughly $500. Looks like many Chinese audiophiles prefer those old junks compared with new production tube amps that they sell abroad.

Victor A-X1000 looks very good, quite impressive. The Pioneer A-900 looks ordinary but has separate transformers. The Sansui alpha 607XR looks no different from new production AVRs you see in AV shops, poging pogi parang brand new, but comparatively heavy about 20 kgs. Haven't heard any of them but based on current resale price in Japan, if I have the space for a new big amp, it would be the Victor.

Early on, napapadaan lang ako once sa pier na yan pasyal pasyal lang with no intent of buying anything (di pa ko nababaliw non sa vintage amp, but the model was impressed on my mind because of the way it looks - guapo) and saw that model. ang siste, gala lang ako non at di pa nagbibibili ... later ko na lang nahagip yung mga web site about this gem amplifier ... sayang, di ko na sana pinakawalan!

Chances are:
(1) you will just be listening at 2-10 watts power
(2) 6 ohms does not matter, its OK
(3) your speaker is safe
(4) if you pump at 40W, the sound may still be clean from the amp, but your speaker is already distorted
(5) if you are experimenting beyond 40W, you may have more diaphragm than what you wanted (I mean, they will be in pieces  ;D )

Seriously, there is no problem with your proposition. There is more issue having low power amp to a high powered speaker.  ;)

Guys,

I too started my real audio set-up back in 1989 with a surplus amp I got from Raon. It was a NEC Django (forgot the model). It was really %$@#$ heavy due to the huge transformer. It has an orange VU meter going sideways indicating 180watts.

After all these years, I had been very interested with all these equipment parts upgrades and modification. Here are some tips so that you could keep your newly acquired surplus amps in tip-top condition and improve its performance.

1) Electrolytic capacitors are the one that will normally fail over time. The liquid inside these capacitors tend to dry up or in some cases leak out. As these amps are already more than 10 to 15 years old, it is the best to replace all these electrolytic caps. To be safe, just use the same capacitance and voltage rating (you could increase the value of the voltage rating but don't go lower in vale). For the power supply caps, you could increase the capacitance to twice the value and by doing so will improve the bass performance of the amp.

2) Get a service manual so that you could set the correct bias setting. Some amplifier runs hotter because they are more into class A, meaning although the amplifier is considered Class AB, biasing it higher will make the first few watts more into Class A. A higher bias means a smoother sound, with the bass becoming more controlled and rhythmic.

3) Bias the dc offset to zero or as close to zero if the amp doeasn't comes with a circuit to automatically check the dc offset.

4) Check for any rusty connectors or cables (corroded/rusty). Replace them with better types you could get.

5) Clean all the contacts and connectors with a contact cleaner like a CAIG contact cleaner or if you are on the budget, get the Philips (red can) contact cleaner.
(http://www.sanace.com/Spray_Cleaners/PHI_390CCS.jpg)

Here are some tweaks/parts upgrade you could do to further increase the performance of your amp.

1) Replace the powersupply diodes to ultrafast/soft recovery type. Get the HFA series from International Rectifiers. Source is Farnell.

2) Replace the Zobel Network circuit. This circuit is a combination of a capacitor and resistor found before the speaker terminal/connector with a good polypropylene cap like Auricap or Mundorf and resistor like Kiwame.

3) Replace the internal cable leading to the speaker terminal and to the output RCA jacks with better cables.

4) Replace the speaker binding post and RCS connectors to better quality type.

Happy tweaking.

Masusunog naman talaga ang speaker mo pag tinodo!  :o But (like pagputi ng uwak will never happen) if you are using it for listening, 10 watts is almost ear breaking level or distortion (for low power speaker) for decent sensitivity speakers, and you may not want more than that level. And there is no telling that when you make todo, it will not hit what we call clipping conditions (giving you DC voltage, and will put your amp in a short circuit condition, burning your speaker earlier than it can burn your amp).

The reason you should be more cautious with low-power amp is that you can easily reach the clipping condition in them than with a high power amp! The speakers are more tolerant of power handling provided they continue to vibrate within its limits, otherwise the cone cant vibrate anymore to the dictates of the power, and at its cone vibration limits (extreme up or down), it is in short circuit condition, either burning your speaker (typically earlier) or your amp (seldom happens) or just reproducing your cones into many pieces  ;D

I remember my college days when me and my brother tried to destroy a 10-watter Micro speaker, justifying a purchase of new ones, by subjecting it to high power amps and make it vibrate (in a listenable fashion) hard. We failed to bring the speaker to its knees!  ;D

Then recently I got hold of a 3 watter national speaker (10incher). Pinahiram ko sa clown with a JVC mini compo at 70wpc para daw sa celebration, anak ng tokneneng, di na kuntento sa lakas (bingi yata), distorted na tunog, gusto pa daw niya itodo, e di na gumagalaw ang level sa display ng JVC (meaning todo na talaga!  >:( ), ayun, lasug lasog yung diaphragm ng ibalik sa akin. Clown talaga!  ;D

But we are talking here of 3watter. It was burned not because it received more power than what it can take, but because the amp reached a clipping condition!

1. what are the difference between Integrated Amp, Power Amp, T-Amp and Pre-Amp? medyo lito ako sa terminologies ng mga amp e.

2. i'm using a yamaha receiver (rxv440), pwede ba ako magkabit ng amp sa receiver ko, sa subwoofer out ba ng a/vr ko ba pwede ikabit? anong klaseng amp ang pwede, pre-amp lang o lahat ng klase ng amp.

3. pag may nakakabit na amp sa receiver ko, dapat dun na lahat nakakabit sa amp yung mga spker pati subwoofer?

I hope you can answer my questions, Thanks and God Bless  ;)

the flow of music signal:
CD player --> pre-amp --> power amp --> speaker

Integrated amp is the combination of pre-amp & power amp

T-amp is another breed of amplifier implementation (just search the net)
Sonic T-amp (the usual focus of discussion being addressed generically as T-amp) is another integrated amp in a small package.

technically, the sub out is an output of your receiver's sub preamplifier. ideally, power amp should be plugged into it. but you can also connect integrated amp (just watch out the level). Subwoofer like DTX has just power amp in it. Of course, it will only produce low frequency.


3. pag may nakakabit na amp sa receiver ko, dapat dun na lahat nakakabit sa amp yung mga spker pati subwoofer?

No. Only the low frequency driver (passive or unpowered subwoofers) should be on that external amp (it only produces low frequency being a sub out)

biasing amps are done to meet certein distortion characteristics, specs if you will...vfets or mosfets can be run hot becuase unlike bipolar transistors, they do not suffer from secondary breakdown.

that you can not detect any difference between a hot running amp, and a cooler one, reinforces the fact that distortion levels are barely discernible...if you measure distortion with a THD meter, surely figures will show that distortion is higher in a cooler amp than that which run hot ....

besides, there are advantages to running the amps cooler, it means longer life for the unit... ;D

3. pag may nakakabit na amp sa receiver ko, dapat dun na lahat nakakabit sa amp yung mga spker pati subwoofer?

No. Only the low frequency driver (passive or unpowered subwoofers) should be on that external amp (it only produces low frequency being a sub out)

Thank you so much sir aHobbit, medyo nalinawan na rin ako sa wakas re Amplifiers ;)

Btw, i got this one yesterday sa Bodega surplus malapit sa amin sa Malabon, 1 amp lang yung available for sale nila, yung Aurex, pero di ko matandaan yung model, kaso nung tinest na namin, ayun umusok, hehehe buti na lang sa kanila ngyari yun  ;D ;D ;D

And then the owner decided to offer and sell me his amp, yun yung kasalukuyang ginagamit nila dun while i'm looking for some items... since tested na nila, and after a long tawaran, binili ko na rin hehehe   ;)

For those who need free schematics for their hifi equipment -- from amps to turntables -- you may want to visit Jas' website: http://www.hifiengine.com/manuals.shtml

It's not complete but it's the best source, so far, for free manuals.

biasing amps are done to meet certein distortion characteristics, specs if you will...vfets or mosfets can be run hot becuase unlike bipolar transistors, they do not suffer from secondary breakdown.

that you can not detect any difference between a hot running amp, and a cooler one, reinforces the fact that distortion levels are barely discernible...if you measure distortion with a THD meter, surely figures will show that distortion is higher in a cooler amp than that which run hot ....

besides, there are advantages to running the amps cooler, it means longer life for the unit... ;D



Yes, my amp (NEC) runs hot ... and am aware heat is my no.1 wearing factor of the amp FET devices ... so I tried to cap it by putting exhaust fan on top to help heat sink cool it, to minimize wear and tear due to heat!

distortion is almost a non-issue in a decent amp - even not a TOTL - they are almost near perfection. There are substantially large distortion in the speaker itself, then multiplied by the listening room - putting amp distortion to zero - nil (moot and academic). This is the reason nobody can hear the amp distortion factor - because it has been masked already by tremendous speaker distortion. Of course, measuring devices can detect it (electronically) - but it can not be heard in real-life condition. So much about golden ear - if there is a perfect speaker (that has much less distortion than the amplifier itself), I could have believe those golden ears!  ;D

Dear all,

I was just wondering who bought the Pioneer A-900 located at Little Chatty's last Saturday AM. It was raining pretty hard that morning. What a brave soul.

Was told of this by Mark a few days prior and was very curious how it sounded. However, I was tied up with work and unable to visit the shop. Was only able to make reservation up to Wed 1pm but did not show up on the opportune time.

To the person who bought it, how does it sound?

I was in Pier last saturday, bought a Denon CD Player. I just sold my Musical Fidelity Elektra a couple of weeks ago and Ive been using my Pioneer DVD as my transport. Anyway this CDP I chanced upon is heavily built, weighs about 2x a regular CD Player and the sound . .WOW!  It can go head to head with my previous Musical Fidelity.

i was also there last saturday with my kumpare and kumare, nagpasama sila sa 'kin bumili ng tv, we were there at around 11:30am to 12:30pm, then kumain kami saglit sa binondo and balik ng mga 2pm to pickup the tv, kay cris kami bumili... sayang di tayo nagkita-kita, hehehe ;)

Anyway, sarap mag-venture dun last saturday, umuulan pa :D

Para hindi OT...
i saw a lot of amplifiers na ok sa little chatty, and even saw a pioneer DTS receiver dun sa loob malapit sa mga tv stalls, selling for 8K, 7.5K last price daw, makinis at gold finish. Unfortunately, hindi ko kinuha, ala budget and iba kasi ang hinahanap ko e :)

Hi Sirs,

I was at our favorite mall last Wed to have one of my amp repaired. I saw a Pioneer amp M-73. I was contemplating to get it but it was not yet in my budget. Hello price of 6K with 100V 500W transformer included.

Post by: sandawa on Oct 06, 2007 at 01:24 PM
Way overpriced. At 75,000 yen original price, Pioneer M-73 should be retailed (based on comparable local sales of Japan-standard used units ) from P3K to P3.5K. That jibes with the average auction price for a used unit in Japan for this unit, which is roughly 8,000 yen or about $70.

Hi Sir,

Thanks for the valued input. Mataas pa pala yung muntik na tawad ko at Php4K.  So dapat pala 4K inclusive of the Xformer.
Title: Re: Surplus amps
Post by: sandawa on Oct 06, 2007 at 04:18 PM
I think the free transformer is a generic type not the branded ones. I was once offered at the Pier a transformer with claimed rating of 500 watts and 100 volts at P500. I thought it was too inexpensive (branded 500-watt transformers were selling at P1.2K back then) and too light for such rating. Also when we measured the output, it came out 115 volts not 100 volts -- well, in Manila, it's dependent on location -- but I still don't trust those generic Pier transformers.

Just sharing in case anybody of you is interested.

if what i read on the catalogue is right, there are two power transformers inside the amp, therefore, it is possible to wire their primary windings in series so you can plug them in direct...if your meralco does not exceed 220 volts, it is highly possible to do this..

even at 4k i will consider it a good buy.... ;D

Hi Sirs,

Thanks for the inputs and advise. Yes the transformer are the red (I suppose pier DIY) ones which they often sell here together with the surplus TV's, I agree might not be really 500watts. Wala na rin siguro ito by the time I return there.

* Power amp direct (bypasses all tone, filters etc for purer sound).

Gusty bass, sound smooth & dynamic.
More transparent & clean through the power amp direct inputs.
Listening to freeview through this amp is a complete revelation didn’t realise a freeview box could have geniune fidelity (digial input).

* Technics high speed smoothing caps in anti resonant housing,
* Large OFC frame transformer & chassis bars for less resonance.
* Rated power 115 watts per channel RMS into 8 ohms & 150 watts into 4 ohms continuous per channel.

thanks sir Tony, I just noticed that its hard to pair it to high sensitivty spkrs(90db up).
maybe its because this amp is really powerful.
Based on the specs that I read on the net it is 100W/channel @ 8ohms

Title: Re: Surplus amps
Post by: rpm on Jan 08, 2008 at 02:19 PM
I had a very limited time to listen to the Technics SE-A5. Comparing it with my ST70, my initial impression is it delivers more details, especially in the mids and highs frequencies.  The bass is likewise tighter.  Maybe because of the 120 watts per channel power it packs. 

However, the st70 is still "mas mataba", although the difference is that that big. The ST70, moreover, delivers a warmer sweeter sound. 

I like st70 for music that are more laid back (jazz and standard), and the Technics for music that are livelier (rock and pop).  The Technics maybe more versatile.

For me it is still too early for me to tell which amp I prefer, I hope that his helps.

Gears used:

Preamp: Dynaco Pas 3 Preamp
CDP: Onkyo Liverpool (surplus)
TT:  Technics 1200 Mk 2 (courtesy of Blondie)
IC:  DIY silver interconnects

Gears used:

Preamp: Dynaco Pas 3 Preamp
CDP: Onkyo Liverpool (surplus)
TT:  Technics 1200 Mk 2 (courtesy of Blondie)
IC:  DIY silver interconnects
speaker cables:  Monster cables (I do not know the model)
speakers:  Boston Acoustics T830 (floorstanding)
               Monitor Audio Bronze 2

thank you for the reply - coincidentally we have similar gear:
technics sl1200
dynaco pas 3 preamp
monitor audio S1

regards

Just sharing my 1st vintage receiver somebody beat me with its 165wpc bigger brother the SX -1250 (isang araw matye-tyempuhan ko din to   :D) so I setlled for this SX-1050 which I also a good amp at 125wpc I got it from the same owner of the 1250. For the time being its replacing my surplus SA-8800II.

The price deal was ok, its the freight that kicked me extra as I have to shell approx another Php 1800. The amp is in prestine condition the RCA's at the back has no rust. The wood panels are perfect, except for the small dings at the bottom portion everything is perfect, no scratch despite the age and the glass panel is crystal clear. Heavy at 23Kgs.

The mids and highs are detailed and bass is deep considering I am only using ordinary speakers. The tone controls are my personal favorite the same feature it shares with the SA8800II you can adjust the 50Hz and 100Hz frequency for the bass and 10Khz and 20KHz for the treble.

I cant wait to open to see the innards.  ;D

Hello Dana,

Yes, although ala naman talaga surplus dito. Im using an ordinary speaker given to me by a relative dito, a bookshelf Precision Accoustic, made in China, but Im surprised maganda tumunog speakers na to.His P.A. floorstanders also rocks, I hooked it up in his Sansui 8080DB oks na oks din. Itatapon na sana daw nya kasi his not using it for a long time na and he bought it brand new daw dati kaso nung sinet-up ko and hooked it up with another vintage teac player ayaw na itapon. he he he he...sayang.... ;D

hi karipas,

nice amp you got there. hope you don't mind sharing where you got it from and how much. sana may kapatid pa yan :) kindly pm :)

i also own a couple of surplus amp. marantz pm50, onkyo a775nII and my main amp is a sony ta-f333esg. all in perfect condition. nothing beats these vintage/surplus amps in terms of value and sound. you have to shell out at least 30k on a new amp to get similar performance.

wanted to try the much hyped sansui and pioneer sound. anyone selling :)

thanks,

brubeck

Hi Brubeck,

I got it here in Canada for Php10K on the prevailing CAD to Php rate and compared to the receivers na nabenta BS section di naman masyado malayo price kaya kinuha ko na. Madami nagbebenta dito but of course di hamak na pinakamura sa surplus mall natin, too bad wala na din gano interesting dun. I visited the place before leaving last Nov maidagdag sa basura ko kaso wala na talaga.

Happy hunting on the Sansui and Pioneer. IMHO (at least on the units I have) Sansui is a warm sounding amp and Pioneer is in the bright side and I like both. Try reaching Sir Bhongskie, he sells a lot of good gears at the BS. Our friend Dana here has quite interesting vintage collections of both Sansui and Pioneer.

Thanks, kaya nga lumunok muna ako bago ko binayadan. I agree, mahirap nga maghanap sa 'tin, sabi nung seller binabaan talaga nya price by CAD100 kasi he knows shipping is costly ....di talaga maiwasan yung kati Sir, actually wifey doesn't know about it yet... ;D sana di nya makita posting ko dito. I also accidentally found another interesting item here, a Kenwood KT-8300 tuner. Owner told me that somebody reserved it 2 weeks ago kaya he faced the unit on the wall and supposed buyer was to get it today but has not heared from the guy yet. I told him by Monday if item is still in his store I'll get it, he agreed....abangan.... :D.

Hello Sir Rodel,

Meron pero bihira naghahanap din ako dati sa mall pati power amp pero I was not successful. I suggest if you want it as in right away and your budget permits get a good pre-main amp na lang. What I do is if I want more power I use the pre-amp of one of my amp then I attached it to the main-in of my more powerful amp. Suggestion lang po.

Thanks Sir, ito ang maganda after I got this unit,.....there was a guy selling his SX-1250 willing to drive near my place at reasonable price..>:(....sayang its 165wpc with 4 mug size filter caps inside about 29Kg, it's not as good as my amp in the pictures but defenitely a very mean amp.
and today I got a chance to own a Kenwood KT-8300 tuner, the owner is increasing the price apparently there is somebody buying higher (parang experience ko din sa pier pagbalik ko iba na asking price)  ;D. I told him I can buy his asking price but I am dissapointed with him because it was not our agreement then I walked away  >:(....Better luck next hunting trip na lang :D
Title: Re: Surplus amps
Post by: brubeck on Jan 22, 2008 at 08:50 AM
kenwood is quite good with tuners and so is sansui. but if you can find a mcintosh tube tuner then that would be a real gem :) but also be in the lookout for dynalabs, dami yan dyan as i think it's a canadian brand?



Title: Re: Surplus amps
Post by: karipas on Jan 22, 2008 at 10:43 AM
Yes, I have a Sansui but I gave it to a cousin when I left, maganda kasi ang reviews ng KT8300 sa fmtuner.com and could have been one of my best buy based on initial agreement namin. I'm saving the best brands for last.  ;D madami din for sale mga yan dito and at e-bay kaya lang madugo presyo, marami kasing enthusiast dito. Inuuna ko lang muna yung medyo kaya pa ng budget.  ;) pagnaka bwelo na ko dadating tayo dyan sir.

if you know how to dismantle the feceplate and remove the top cover. then the best way to clean will be wash it with detergent soap and water to remove the grime and dirt.. then wipe it dry.

I believe wipe out is water based while mc is oil based, kaya safer parin ang mc specially for metal casing of amps. Wipe out is intended for pc plastic parts kasi ata at baka may bleach para pumuti uli ung white plastic.  :)

You guys are really lucky to get those amps at surplus prices.  They were also my dreams when starting out in this hobby decades ago like the early Onkyo Integra M-class power amps with those huge VU meters and those from Technics and Luxman.  Properly cared for, they are timeless, both as works of art and performance.  Just reading their specs show how relatively pathetic the power amp sections in most HT receivers have these days.

Anyone seen this at the pier?  The Onkyo Integra M504?

hi adjell33.. sorry for the late reply. been so busy at work.
i'm not very good in describing what i hear, its just a feeling. if i like what i hear, that's it. but let me try..
the sansui BA2000 at 110wpc will give you power specially on low frequencies.. malakas tumulak  ;D
while the Lo-D HMA-9500 at 120wpc will give you finesse on mid and high. pino, swabe  ;).. eka nga nung dating nag mamay_ari. and i agree with his description.
hope this helps and your "wish" to come true. good luck !  :)

I havent encountered an M504 but I have seen an Onkyo Integra M506 at the pier around two years ago and it was sold for P8K.  I was able to buy an Onkyo Integra M506R (newer) elsewhere for P5k before that. Very handsome looking amp with large black meters with green lights. Very powerful amp with two sets of speaker outputs rated at 120wpc. Performance is very much like the Technics SEA 5 also rated at 120wpc

Very nice looking sony amp! :o What tube pre-amp do you use this with? I have a similar set-up with a Sony T-AN 330ES power amp with a car tube pre-amp(soundstream) used with a 12v converter for home use!  ;D

I'm using a DIY clone of Bottlehead's Foreplay III preamp, fitted with 2 x NOS JAN Philips 5963 (12AU7 equivalent) and OD3 regulator tube. Info on original Forepaly III:

@rodel

Thanks. Hirap talaga may sakit na SARS. :)

Naka swerte na walang pumatos nitong amp na ito sa pinoybazaar, heh-heh, considering na almost a week nang naka post and I have to travel from my home province Nueva Ecija to Manila to pick it up, heh heh.

Sir, kayo ba nag diy ng foreplay III ? How much did it cost? Very interesting ha! parang gusto ko rin mag pa diy!  ;D By the way, san kayo sa N.E.? My wife is from Gapan and I worked for 1year sa DHL Cabanatuan branch.  :)

Konting review naman sa sound quality ng diy foreplay!!  ;D tnx.

Sir, I bought theForeplay pre-owned from the PDVD marketplace. It was originally planed to be paired with the Trends Audio TA-10.1. Hooked to a vintage late 60s Pioneer 3 way speakers with 12" woofers, the preaamp+TA-10.1 combo sounded great, better than the Trends TA-10.1 without the pre-amp. As my wife put it, mas malinis tumunog. Then a frined (also a fellow PDVDer) loaned me a tube power amp, a single ended EL34, and to me the all tube combo sounded way better than the Trends TA-10.1+preamp. Up to moderate listening level, the Trends TA-10.1+preamp sounded a bit better overall than the Sony TA-3200F+preamp, but the Sony TA-3200F starts to shine as you crank up the volume. :)

I've been living in Munoz, Nueva Ecija for the last 23 years. And BTW, I'm newbie on this addictive audio hobby. :)

I havent encountered an M504 but I have seen an Onkyo Integra M506 at the pier around two years ago and it was sold for P8K.  I was able to buy an Onkyo Integra M506R (newer) elsewhere for P5k before that. Very handsome looking amp with large black meters with green lights. Very powerful amp with two sets of speaker outputs rated at 120wpc. Performance is very much like the Technics SEA 5 also rated at 120wpc

I purchased an Onkyo M506 at Little Chatty's almost 2 years ago. Got it for 8K. I wonder if this is the same one you are referring to. After a year, sold it to a fellow PDVDer. I believe he still has this today.

di ba mas matanda pa mga tube gears (mga vintage)type na kinalolokohan ng iba and yet still working ;D?

IMO, before going to tubes all the way, better to hear a nicely maintained vintage SS gear at baka magulat ka or di mo lan talaga matanggap ;D :o ::) dahil kailangan mo sumabay sa uso/fad at gusto ng madlang people. ;D...(not directed at you but in general :)....)

besides, these vintage gems have witnessed the golden era of  audio and somewhat created a cult following from hobbyist and collectors due to their built -like  a  tank &  good SQ reputation.try to browse in audiokarma site, dami naloloko dun sa vintage SS, not only in tube gears.

what can be done is recapping of electrolytic parts (specially those in the psu...) since they have reached  somewhat their lifespan as I understand...however, sa ibang forum (audiokarma),they debate these... for the other parts, transistors, ics etc...with proper design and operating points, they will last many  years (as I undertand from readings...)...baka nga mauna ka pa sa kanila ;D

matibay ang mga yan at hindi pahuhuli sa mga plastic looking new production models.
the circuits in new production models  mostly, are nothing new ...(mostly adapted and sometimes improved upon based from these vintage SS gears...).

maybe, retro is a lifestyle too. some may be attracted with their gleaming thick aluminum knobs, etc. have  some vintage ss gears too, mostly never been touched except for some minor maintenance (pot cleaning, resolder some points,dusting etc) & TLC.trying to play them all  on rotational  basis or depende sa mood for different flavors & characters. appreciate the history, engineering and science in these audio toys.

Agree ako dito doc, meron din akong Onkyo Integra A-755, almost tube sounding kaya kahit na burado na ang nakasulat at mas matanda pa sa akin at minsan tinotopak, di ko pa rin dini-dispose, ginagamit ko pa rin hanggang ngayon :)

Actually you have a point sir dana, kelangan lang talaga tayo maging open minded, dati kasi parang naging fixated ako sa tubes, pero when i got the marantz parang it opened up a whole new world of experience for me.

Saw one near sa "suking tindahan" about 2 weeks ago but was not in good condition. One VU meter is busted and one pair of rca  line in at the back is missing.   :(  At nung naglakad lakad pa ako, I saw another one (same  LOD 8500) in another store in better condition  but when I ask (excitedly!) how much, ang sabi sakin nung nagbabantay... pagawa lang daw yon at not for sale.  :'(  Napansin ko nga, repair shop pala yun store.  :-[

Balik tayo sa surplus amp hunting. Sa akin lang, outside of hearing the first notes of music from a newly acquired vintage gear, getting a bargain is probably the most exciting part of this hobby -- like what happened to Rodel. Parang yung life and chocolate box comparison sa Forrest Gump: you'll never know what to expect next.

Last year bago nag-Pasko, may nakita akong sira na Denon POA-1003 (http://www.hifi-museum.com/temp/Denon_POA-1003_fs.htm) sa isang importer's warehouse dito sa amin sa Davao. Okay sa akin ang Denon power amps, I have two units of POA-1001, top of the line in mid '70s na ginagamit ko ngayong biamp sa JBL 4430 ko (Acquisition cost for POA-1001: P5K each -- talagang dapat mahal yung magagandang amps kaya lang super-barat ako.).

Oops medyo nalihis, balik tayo sa defective 1003. "Magkano?" tanong ko sa warehouse supervisor na tubong Novaliches. "P500 na lang," sagot niya. Siyempre, kinuha ko at idinaan sa kilalalang technician. Hindi ko iniwan hangga't hindi alam kung anong problema. Within an hour, nakita ng technician yung 2 defective parts at swerte nakabili naman ako @ P300 for both parts.

Sa madali't sabi nabili ko yung 1003 ng P500, parts P300, service charge P300 or a total of P1,100 lang. Within 4 hours, tumutunog na sa bahay, at pares ngayon ng JBL 4313. Sa Japan Hifido at Yahoo auctions tumatakbo pa ang POA-1003 ng 30,000 to 50,000 yen. So far, ito ang pinakamura kong upscale amp na nabili. Swerte-swerte lang talaga. Sa ibaba ang actual pictures:

rodel5, mukhang para saiyo talaga unit na yan ah!  ;D I was tempted narin talaga kunin yan because sinilip ko ng lighter flashlight un loob at orig pa mga output transistor nyan but wasn't ready to buy that time, nag paayos lang ako ng TV.  :-\  Congrats bro.

Medyo nakabawi rin naman ako, I got a mint Onkyo A-817EX from a friend at medyo mataas lang ng konti price compared sa pier, though, 100v din. Sobra ganda ng match sa 9.1. Before sa dati kong intg. amp, I still need a sub to get good bass from the 9.1 but nung match ko na sa Onkyo, parang naging floorstand yung 9.1 with credible bass, without the sub!!  :o  It also confirmed my theory that wharf speakers really need good high current amp to perform their best.  :D

just a samll backgrounder, your amp was born in an era where "dual mono" construction was a fad in japan, many other amp makers did this, i am talking about dual power supplies and dual transformers....that was a good era....treasure your amp. wala na lalabas pa na kagaya nyan... ;D
Title: Re: Surplus amps
Post by: sandawa on Mar 14, 2008 at 07:00 AM
Yes. The Denon POA-1001s, not my 1003 however, are the true dual-mono blocks: two separate mono power amps, two separate housings joined by a common faceplate. Each amp has four units of 22,000uF (63v) of power storage (capacitors), or 44,000uF per channel (88,000uF per amp). That's one reason why I'm now using two POA-1001s to biamp my JBL 4430 monitors: four mono blocks to drive the two big horns and and the two 15-inch woofers. I bought them all from Davao's surplus market, in good working condition, and comparatively cheap. Photos below (the white residues on the casings were unwiped Pledge which I use as cleaner):

           Maraming Salamat bro Rodel, Pasensiya ka na, na disturb ko ang
    inyong talakayan.  Nakakahiya tuloy ke inang de Lara ,siya pa naman
    ang tigapangtangol ko nuon, pati ang kanyang apo pag nag aaway kami
    ni boy na madalas magalit pag umaagal dahil bakit pag ako ay pinababayaan
    ni Dez na makapamili Ng mga Sony Kirara tv kahit take all na nila boy at financer
    niya.
               Me mga ilan ilan na dumarating sa pamamgitan ng Barko pero
   medyo me kamahalan , hindi katulad ng galing sa container na mura
   dahil ay mga sira. Hindi naman itatapon ng hapon iyan basta basta kung
   walang dipernsiya, kaya meron seller akala buo pero later on pag ginamit ng
   konting panahon ay lumalabas ang sira. iniiwasan din ksi ng mga pinoy tech,
   ang bangungot . Makapagbubuo na sila ng 12 unit katumbas lang ng isang
   bangungot.
              Sa ngayon wais na ang mga hapon , lalo na yung me mga asawang
   pilipina. Iyong kaya nilang ipagawa at umayos dahil ginawa ng kanilang
   batikang pinoy tech  duon ay duon na nila binebenta  o kung dito naman ay
   medyo mahal na, sa container pa lang.
                  Medyo ang iwasan  ay matsambahan mo iyong tinangihan nila
    sa japan at pagdating dito ay ginawa ng tech na piyesa, basta tumunog
    o umadar ng Ilang buwan at iyong orig value parts ay tinapon na.
                        Meron ding k na k diyan sa pier pero mahal.
 
                                 Enjoy ur amp rodel. K  lang iyon

rnb_zounds, yup bro exact piece un pics mo!  ;D Ganyan din ka sariwa.  ::) All I can say is naging Onkyo Integra believer na ako since using this amp. Before kasi I had mediocre experience with Onkyo amps but those were not Integras, just standard Onkyo's. But this model really surprised me and as they say, "jaw dropping" . :D 
My initial impressions are a very wide and deep soundstage with a very good imaging. Very quiet and clean kaya I can pinpoint each instrument and hear subtle sounds. The character of the amp is on the warm side with neutral and flat frequency. Actually, medyo laidback yung highs (compared to a tube pre-amp/ss poweramp combi) but more musical for me.
I read somewhere that this 817EX has the same character with the 817XX but is different from the 817RS. Medyo boomy at pronounced ang high nang RS daw.
I also got a Marantz/BMB D-3 integrated amp which also surprised me a lot with its musicality since, this amp was really intended for videoke!  ??? I will post some pics to show it. Very macho sya kasi it uses the chasis/heatsink of Marantz Esotec PM-4 and also very hefty (read: super heavy).  ;D

Title: Re: Surplus amps

how much kaya sa pier etong integra a-817ex?

sa price ng importer na be base sila sa wattage consumption ung nasa likod nakasulat.100/watts presyo nila.
 example: 350watts,3.5k presyo ng importer,syempre magpapatong pa ng mark-up ung retailer.yan eh according dun sa kilala ko na importer.
Title: Re: Surplus amps
Post by: sandawa on Apr 02, 2008 at 10:25 AM
Just to confirm the previous post based on my experience. The ongoing retail price for surplus amps here in Davao where I live is wattage consumption at the back multiplied by 20. The retailer may quote a higher price but after haggling, you'd likely get the "times 20" price, or even lower. For instance, the Onkyo 817 series sells here at a range of P3.5K to P4.5K depending on the model and the unit's condition.

Yesterday I went home with a new production gold-toned JVC amp (AX-V1), which is small but looks and weighs awesome for its size. The wattage at the back says 175, so my friendly trader gave it to me at P3.5K. Plus, I also picked up a mint-condition Technics SB-7000 linear phase speakers (OT).

Here's a tip, again, for those hunting for high-quality vintage Japanese hifi:

1. If you want to know where your target equipment is placed among hifi models sold during its time, as reflected in its original retail price, then check these websites:

http://www.audio-heritage.jp/
http://www.niji.or.jp/home/k-nisi/index.html

Translate using Babelfish: http://babelfish.altavista.digital.com/
The audio-heritage site provides only basic info such as original price and description. The niji site provides the website owner's favorite vintage models and his commentary.

2. If you want to know which of the vintage models are highly regarded by Japanese audiophiles, as reflected in high resale price, then check these sites:

http://www.hifido.co.jp/sold/indexe.html
http://yackdb.s138.xrea.com/htmlmb/index.html

In the hifido site, all you need to do is type your equipment model number for previous transactions data to come out. If your equipment is not listed in hifido, it is likely a minor model and not highly marketable in the Japanese used market. For the yackd site, which is more comprehensive, click on the letter that starts your equipment model code and search for the exact model number. Click again and a list of the most recent auctions completed will then come out.

The hifido data is generally better since it provides prices for good-condition units, those they sell in their outlets all over Japan. The yackdb data are from Yahoo Japan auctions and could include junks or defective units. Sometimes the items listed are mere user's manuals and not the actual units.

In the '80s and '90s, I was hooked mainly on British and US equipment. Nowadays, I'm crazy over these vintage Japanese gems. Most Japanese high-end hifi units were not sold in US and European markets and that's the reason why American and European audiophiles are willing to pay high prices for these vintage equipment. One of the emerging businesses in Tokyo nowadays is forwarding of vintage hifi since foreign audio enthusiasts are willing to absorb the high cost of importing these "junks." (Europeans who are members of Audio Karma said the total cost of an imported unit is about twice the price quoted in Hifi Do.)

Some minor problem sa balance and volume knobs, Already brought it to Mr. Andrew Yap for repair courtesy of Oweida. pero i think palitin na din some of the capacitors.

Post by: sandawa on Apr 04, 2008 at 08:35 AM
This is awesome! Did you buy your a607 MOS Limited in Japan, or was it forwarded here? This would be very expensive if bought thru Hifido; could be over a thousand dollars even without  forwarding charges and tariffs. Used Sansui's prices, especially the alpha series, in Japan have doubled since last year due to high demand from Europeans I was told.

In England, France and Germany, very expensive 100-volt transformers are now available from audiophile shops, unlike before. I actually offered to send locally made and cheaper 240 to 100v transformers there but my friends found a supplier that could provide such transformers at three times our local price. That would even up cost of sending 100v Panther transformers when forwarding charges are inputted.

Many European audiophiles are now buying Japanese vintage hifi thru Hifido's forwarding firm (They've put up one last year -- I remember they sent me an offer for their services a couple of months back).

Take good care of your a607. Don't forget to use a dedicated 100-volt transformer on your unit. Also monitor your line's voltage regularly.

I don't know where to buy used power amps there in Manila. Most of my power amps were bought through Japanese importer contacts at surplus prices here in Davao. I bought them low but if we'd be realistic, these power amps should be be selling in the local market four times my acquisition cost, or even more based on Hifido prices.

Thus, a dual mono block Denon POA-1001 I mentioned in an earlier post sold at say P15K would still be reasonable. I have two POA-1001s and one POA-1003, or 3 similar power amps just like what you need, but I have no plan of selling them. Maybe the POA-1003 later, since it's the odd unit of the three but it had to be picked up here in Davao. It weighs over 20 kgs. by the way.

So, you're based in Paris? Are you a Filipino? If so, you could buy Sansui alpha 607 series here in the Philippines a lot cheaper if you have importer contacts. Of course the a607 Mos Limited is special, but I've seen gold-colored a607XR and MR here in Davao early this year being sold at P6K ($150) each. Alpha 907s rarely come in but you'll see a707s once in a while. A week ago, there was an a707i here in Davao quoted at P7.5K.

By the way, I currently own an original a907 and an a907iMos Limited plus an AU-X11, all black. They're in a league of their own. There are many others in this forum who own Sansui alpha series amps, mostly 607s and 707s.

Your email name sounded like you're a Filipino, even a namesake of a professor at the Univ. of Chicago. Anyway, on behalf of the guys here, welcome. You'll find some postings here, in English, on the Sansui Alpha series. There's another site here -- Pinoy Audio forum where I used to be very active -- where Sansui alpha series amps were also discussed. Outside of Japan, I think a lot of alpha series amps were also sent to Vietnam. I was told by traders here since two years ago that the best vintage Jap hifi units are now being shipped to the port of Shanghai in China since they could sell them there at almost brand new prices

There were  several others from Audio Karma, aside from you, buying directly from Japan. I've been getting PMs since last year from guys in Croatia (or Yugoslavia?) and Germany, probably thinking I'm Japanese. There's also an English guy in his early 30s who called me up once from Hong Kong (he works with a bank, shuttling between HK and London) who made a side trip to Tokyo to buy some audio stuff late last year. He was interested in vintage Accuphase and Sansui alpha series amps.

Anyway, give my regards to Axel Dahl, a legend in Audio Karma, who also lives in Paris. Me and some other guys here used to communicate with him on our collection of Japanese amps.

Title: Re: Surplus amps
Post by: sandawa on Apr 07, 2008 at 09:34 AM
Yes, it's a good amp, in fact top of Sansui's regular line in late '70s to early '80s-- reasonable price would be from P6K to P8k from surplus sources, but could go as high as five figures since current resale price in Tokyo goes as high as $700. It's a generation below the Alpha 907 series, however. The original AU-D907 is almost a collector's item and could be a bit more expensive. The D907X, and Limited editions are generally more expensive compared with the regular D907F or D907G.

If it's AU-D9, it's the exported (US) version of AU-D707. In that case it should sell at only about P4k, no more than P5K. Rated 90wpc to 110wpc. Good enough, but not top of the line.

again, thank you very much.

The prices of 300-watt and 500-watt transformers differ by only a couple of hundred pesos. If I were you, I'd buy the 500-watt transformer so you'll have enough just in case you'd buy a bigger amp a year or two from now. "Panther"'s 100-v transformers are usually quoted at around P1,200 in Manila, but if you go to small hardwares where inventory moves slower compared with big retailers, you may find 500-watt 100-v transformers sold at P950. That's the pricing here in Davao from those outlets. "Zebra" with 100-110v outlets is a little bit expensive but the "Highly" brand which is also solidly built is priced like Panther's. Better to have a volt-ohm meter handy since you should check your voltage regularly. I do it every other day to see if my regulators are doing their jobs and if our utility firm here is supplying power at tolerable level.

RE: the non-working digital output, check for small switches in your units; also try the coaxial jack. I had a similar experience with my generic China-made DVD player. I found out it was the generic DVD player's digital output at fault.

Why are you asking. Is there anyone selling an a907KX?

In 1999, I saw an a907KX here in Davao being sold at P12K. I haggled up to P9K I think but the trader who eventually became a friend said P10K last price. I said no, but I went back the following day since I can't sleep thinking about it. Unfortunately, I was told the unit was sold just a few minutes after I left the previous night. Early this year, I had some beer with that trader and when I inquired who bought the alpha907KX and at how much, he said it was sold at P10.5K to a guy in shorts who needs a 400-watt amplifier for a videoke bar in a remote town somewhere in Cotabato.

To tell you frankly, I don't have golden ears unlike many members of this forum. I'm lucky to hear good Sansui and Luxman amps, thus the bias. Had I gotten hold of a great Onkyo, Pioneer, Marantz or other brand amp, they'd probably be on top of my lists too. Re: receivers vs. amps, I don't know, but my main interest is on Jap vintage gear and as far as I know, they did not release receivers in Japan that were highly acclaimed by serious enthusiasts..

Oh i see.....

I'm new to this hobby,
When i bought my first audiophile grade bookshelf speakers, an aurum cantus leisure 2sv,
i thought that using my Pioneer Elite a/v receiver will be fine, until i got a chance to buy a
Sansui 9090db. This time the sound improved a lot when another great opportunity came
along, i had a chance of buying a JBL L112. This releases the great ability of the 9090db to
hear what it is capable of.... reproducing music with authority throughout the entire frequency
range. Clear crisp highs, open natural mids, powerful lows my chest can feel.
From then on, i matched my 9090db with my JBL L112. I use it whenever i want to listen to
orchestra, marching bands, perez prado, and the likes...
So as to the Aurum Cantus Leisure 2SV? It is now mated by another jewel, for i long been
looking for an amp that can satisfy my somewhat critical ear when it comes to vocal
recordings. I'm now enjoying listening to audiophile vocal recordings via my
Aurum Cantus Leisure 2SV and my latest catch....Marantz Esotec PM4....

Sir Sandawa,

Hope you can give me tips on what particular models of vintage solidstate amp are worth owning.....

100 wpc and above and
low powered amps that is good for vocals

Ti'll then sir ;)

How does a Sansui AU-D907F compare vs the Alpha 907 iMOS in terms of sound reproduction?
Title: Re: Surplus amps
Post by: sandawa on Apr 13, 2008 at 07:37 AM
Hi Nelson,

I don't have a rigid rule which is best and which is not. One way is to audition the gear first, and let the ears decide which ones sound good. A better way is to have previous experience with the unit. Many of us would sell this and that and would realize later they sound better than the "upgrades." A lot of those who would PM me on inquiries such as this were disappointed I guess since I would flatly tell them, I wouldn't make a comment or recommendation, even thru PM, unless I have an experience with the unit. Another limitation is that I'm only into vintage hifi and not into new production hifi.

In "speed transacting" or when there is serious competition, however, I would look at internet sources and check the history, specs and the unit's resale value. Like many in this forum, I also refer to test claims of manufacturers. But I hardly buy amps and speakers that were quoted by Hifido below 20,000 yen, unless offered dirt cheap.

Hi Rascal,

The sonic difference between a 907F and an alpha 907 is so significant. To my ears it was like comparing a good 20-watt amp with a good 100-watt amp. The alpha 907s I now have are the closest to the huge Krell and Stasis amps I can only dream of in the '80s.

BTW, I have just withdrawn my interest in the 907iMos Limited due to problems bringing it from Baguio to Davao. Also my trader told me a couple of high-power alpha series amps (400-watt consumption kuno!) are arriving within the week and I'll have the first look.

Hi Terii,

I can't afford Hifido prices, thus I try to go after units that arrive here in the Philippines and hope they're in good condition. The ongoing price for 907 alpha series in the port city where I live is from $200 to $300. Unfortunately, such units rarely come in, could be once a year.  I hope my friend is telling the truth.
Title: Re: Surplus amps
Post by: Nelson O on Apr 13, 2008 at 08:31 AM
Same here sir Sandawa, i'm also into vintage solidstate collecting,
whenever i chance upon a vintage looking amp, i'll immediately
get its model no. and surf the internet for its worthiness, e.g.
good review, price, etc. I'm not into new production amps, cause
good sounding one's is way to expensive compared to vintage heavyweights.
What i can say is, i'm truly enjoying the thrill of hunting these audio gears, much
more when i got home with it and finally taste (hear) the fruit of my labor :D
More often than not, it brings smile and happiness especially if it blends well
with the existing gears.
To this day, nothing came my way which dissapoints me of my vintage audio
journey. Knock on wooden side panels of TOTL AU's ;D ;D ;D

I hope you find that AU..... that you're looking for very soon!
I wish also that someday, i'll be able to have the opportunity of owning even
one of the AU that you have for i have only one which is AU-607f extra :(

Hi  Sandawa

You have a friend who warns trader arrivals
Sansui of vintage is a plus to me by rappoort
I know that hifido is expensive, it is the only that I found at this time in Japan that sends to the international, I am aware that I pay for the expensive sansui
In france is no market for the high-range sansui reserved for Japanese (100 v), one of the reasons I buy directly to japan
I tried at AUDIOUNION: their response, we are incaples to ship to foreign countries

Thanks for those valuable information. Should you need small parts for your Japanese equipment that are unavailable there, just PM me. I may be able to find you some of those parts here. I've done that for a couple of Audio Karma members at no cost to them.

I almost forgot about this. Not OT since this might be important for serious vintage (surplus) Japanese amp collectors. Literature of your gear could be available for sale from The Vintage Knob.

Yesterday, I and probably some members of this forum, got an email from Axel Dahl, our friendly Japanese vintage hifi expert based in Paris. Here's the message:

"To fund TVK furthermore, I am starting a large 'spring cleaning' this week : many catalogs will be auctioned through the german eBay. These are mostly xxx-rare catalogs for Sony ES, Yamaha, Marantz, Kenwood, Technics and others.

"Later on, the rest of the collection will go as well (yes - everything), along some hardware such as NOS spare V-FETs, a Denon TU-850, a CDP-X77ES and more.

"You'll find on TVK's home page a somewhat flashy banner which will take you to the detailed descriptions of what is presently available for sale, or, directly, here : http://www.thevintageknob.org/ebaysales/ebaysales-all.html

Sir sandawa, what's your opinion of the Sansui AU-alpha607 ? Is it collectible and can it pass as a hi-end integrated amp? Also, what's the difference in sound quality between this original alpha607 and it various upgrades like 607i, 607imos, etc.
I recently got the orig. version alpha607 and I found it really good. Compared to my other integrated amps it's more refined though a bit slower in pace. But, boy, it sounds very clean and transparent and particularly best for vocals and classical music.  ;D   
Title: Re: Surplus amps
Post by: sandawa on Apr 27, 2008 at 07:53 PM
In my opinion, any amp under the Sansui alpha series starting with the a607 is collectible since they don't appear in the used market often. I believe the first a607 was sold in the US at $1,200 and in the UK at 1,000 pounds, so, it's considered high-end amp in the US and Europe. However, if you look at it from the Japanese audio enthusiasts' point of view, the newer a607 series, specifically gold-faced a607s like what Terii bought from Hifido are the true collectibles, still selling at over $500 in Japan's used hifi market.
Title: Re: Surplus amps
Post by: allan1836 on Apr 28, 2008 at 02:38 PM
Sir sandawa, thanks for your inputs! I believe this au-a607 is the x701 equivalent in the US. May I also know if the alpha series amps used the Tamura transformers, which might be the reason for it's high price tag.
By the way, a friend has a gold colored Sansui alpha305 cd player. Is this also hi-end? Upon inspection, I found it to be quite ordinary and light when lifted. Thanks again for your insights.  ;)
Title: Re: Surplus amps
Post by: sandawa on Apr 28, 2008 at 03:35 PM
I read somewhere that some transformers in upscale units released later such as a907 series and the AU-X series, actually used new transformer technology (which could have been improved thru the years). It's possible the expensive a607s may also have those transformers inside.

My opinion is that any alpha series below 607 could be ordinary.

Just a tip for those hunting for good vintage amps, I have spotted an alpha 607L Extra (black):
http://www.hifido.co.jp/KWa607L+Extra/G1/E/0-10/C07-33006-99883-00/

and a Marantz PM-80 (gold):

@parasmi, malapit na rin sana akong mawalan ng pag asa, salamat nalang sa internet, napapadali ng kaunti ang paghahanap, papindot pindot lang. nakita nyo rin pala yung selling  price. akala ko nga typo error. eto ang clincher. alam mo naman tayong mga pinoy sa tawaran, kahit na sangkusing basta maka tawad ok na. i was VERY, VERY willing to pay the asking price kaya lang di ko napigilan ang sarili ko, instinct na siguro. tumawad pa ko (without malicious intent, i believe in karma), and to my surprise, pumayag naman. di ko tuloy alam kung matutuwa ako o makukunsensya. but its all water under the bridge now. at ngayon, text mate na kami nung seller..  :D

@Nelson O, salamat sir. mahilig ako sa nilaga, kaya ganun nalang ang aking tyaga.  ;D

@dana, thank you sir. I do believe good things come to those who do good things. And to top it all up, kindness you can never giveaway for it keeps coming back. to you, your family or friends in one way or another..  :)

Impressive specs, Southpeak. I'm a fan of vintage gears myself (Luxman L-410, 75wpc, 220V, not surplus though). Despite owning more current brands, listening to a vintage feels like having a piece of audio history at home. Old-school has its own allure.

thank you sir. the specs is just half the story. 90wpc is just a smoke screen. once you hear the sound it can produce, you’ll know immediately why kenwood put the TOTL badge on it. amazing sound stage. :o
nirvana? if happiness and fulfillment  are my yardsticks for nirvana, then i always reach it every time i listen to what i have at that moment.
wow, luxman. i’m also waiting for that brand to pass by my way. hoping to own one too  :)

“PATIENCE, PERSEVERANCE, HOPE” virtues “bakaleneos” must have.
Yesterday when whole of metro manila was preparing itself for an afternoon siesta, the owner of this magnificent machine decided to post it for sale with an incredulous asking price AND a pioneer tuner as freeby. I was also preparing to rest with my children but then decided to go on line for just a quick look on my favorite hunting sites. I was not expecting too much because I’m aware that the friendly competition out there in finding such gems has already become an ordeal, almost near impossible. But alas, maybe I did something nice that day and the audio gods decided to give me some luck. I was eight in the viewers count, no time to loose. i pounced on it just like a lion on the prowl for game. And the rest is history.. fantastic!!!!


“PATIENCE, PERSEVERANCE, HOPE”   ;)

Wow, tempting to acquire your gear!

I enjoy watching those early types of dual mono - I feel it is more a work of art than technology - better open to appreciate than closed. Very rare gem that you can encounter - dual monoblocks - expensive by todays standard. I own similar NEC A-10II that uses dual EI transformers like yours, sealed pots - no harsh dial anytime, and never got an inkling to dispose it - and I think you won't. Congrats!

Looking at your Keenwood, it was quite impressive seeing the dual mono design. Ang hindi lang yata maganda ay ang paggamit in IC chip for the output stage, based duon sa picture.

But anyway, the designer could have taken this into account dahil ang sabi mo nga eh, maganda siyang tumunog. Ika nga, ang importante hindi ang laman sa loob, kundi kung paano ito tutunog.

Happy listening. :)

To hear the Esotec PM4 with a Dynaudio Audience 60 recently is a system worth keeping for life. Ive always been a pre/power believer but this combo can deliver everything you want your music to be played. Truly in a class of its own. ;)

yes sir, almost same comment from my tech. sabi pa nga nya, pag ka daw yung IC ang bumigay, himala na daw kung may makita pa dito sa pinas. benta ko na lang daw agad bago madedbol  ;D. mapag biro si tech  :D
actually there are two ICs, the TA-100WA and PA63H (from service manual)..

and yes, the designer must have seen (or heard) something special from these ICs to include them in the system and give the amp its "soul".. maganda talaga sir.  :) lets enjoy them while they last..  ;)

oh, btw.. for those who are interested. the units' japanese counter part is the TRIO KA-7700d

have no fear..... :)

that IC contains a darlington pair, bias diodes and resistors..Sanyo and SANKEN makes these hybrids, they contain transistor chips and diodes and resistors in what is called thick film technology) .......in the event of failure and no replacement is found...you can always convert your amp to discrete transistors....it can be done...i have done several conversions before...... ;D

Just to alert you guys, some upscale gear have been arriving here in Davao these past months although just a fraction of the usual volume of shipments 5 years ago. Check out your friendly traders there at the Pier. Ask those guys at Chatty's. Malamang meron din dyan, baka nakatago lang. Today, a trader here in Davao told me of two alpha 907s (iMos-Ltd., and 907L-Extra) that arrived last week and sold immediately to some guys (nakalimutan akong tawagan sa bilis ng mga pangyayari!).

Since last week, 2 pieces of Onkyo Integra 927s are displayed in one shop here at P6K each:
http://www.audio-heritage.jp/ONKYO/amp/integraa-927.html

Anyway, if I get lucky, I would have a Luxman SQ-38 Signature (valve integrated) this weekend. 

Three months ago, I got a Sansui AV-9500, the last top of the line Sansui AV amplifier:
http://www.audio-heritage.jp/SANSUI/amp/av-9500dsp.html

Last month, I was able to buy a Yamaha C-6/B-6 preamp/power combo:
http://www.audio-heritage.jp/YAMAHA/amp/c-6.html
http://www.audio-heritage.jp/YAMAHA/amp/b-6.html

Last week, I got this rare and amazing Diatone DS-S3 with 4-inch downfiring woofer that pounds like a 10-incher:
http://www.audio-heritage.jp/DIATONE/diatoneds/ds-s3.html

I'm getting excited again.

Hi Sandawa
   
Congratulations on your purchase, in France we do not have a surplus of hifi equipment from Japan and it is a pity
but I managed to buy a Sansui 607 NRA2
Now I await the arrival of 607 NRA2 from Japan, it took 10 months for having

Title: Re: Surplus amps
Post by: sandawa on Oct 21, 2008 at 03:47 PM
Dana,

Wala, hindi na-deliver ang SQ38 Signature -- medyo mataas din ang presyo P24K (but selling at $1,200 in Japan now) -- ang sabi ko sa trader babayaran ko kung walang hum na maririnig after two hours the amp was on and playing one watt per channel. Hindi dumating last weekend, that means merong hum, which is the usual problem among tube amps. I can't stand even a small amount of hum since I've heard good tube amps abroad without any hum. My current Sansui AU-70 has no hum. My Dad's Radford and Dynaco amps back in the '60s have no hums and he told me when I was starting never to buy any tube amp with a hum.

Hi Sandawa
   
Congratulations on your purchase, in France we do not have a surplus of hifi equipment from Japan and it is a pity
but I managed to buy a Sansui 607 NRA2
Now I await the arrival of 607 NRA2 from Japan, it took 10 months for having

Hi Terii,

So you're also into hoarding Sansui's best amps? I'm not lucky enough to get those a907s that drifted in the city where I live. Had I got those two, I would have three different models of alpha 907s (2 units of imos limited) now plus an AU-XII, an AV-9500DSP, an AU-D907F and an AU-70 (tube). I'm luckier though with good quality vintage Yamaha power amps. I now have the C4/B4 combination; the B3 (VFET); and the C6/B6 combination. I'm not a big Yamaha fan but they seem to come easily to me.

Dana,

Wala, hindi na-deliver ang SQ38 Signature -- medyo mataas din ang presyo P24K (but selling at $1,200 in Japan now) -- ang sabi ko sa trader babayaran ko kung walang hum na maririnig after two hours the amp was on and playing one watt per channel. Hindi dumating last weekend, that means merong hum, which is the usual problem among tube amps. I can't stand even a small amount of hum since I've heard good tube amps abroad without any hum. My current Sansui AU-70 has no hum. My Dad's Radford and Dynaco amps back in the '60s have no hums and he told me when I was starting never to buy any tube amp with a hum.

Hi, Sandawa

Terii,

So you got your a607NRAII from HifiDo?

I was searching for an email from an American guy who operates a forwarding company in Tokyo. He once offered his services to me in bidding for items in Japan's auction sites. Unfortunately, I couldn't find his address. Anyway, I googled and what I got are these two sites:

http://www.japantoy.biz/
http://www.aazumatrading.com/yahoo-auction-japan/index.php

Do you have experience with any of these two? My acquisitions are currently dependent on my trader-friends here in southern Philippines and I'm planning to buy directly from Japanese sources for small hifi items one of these days.

Hi Sandawa
   
the NRA2 which was sold on hifido, yes I am the buyer, since the beginning of the year there were 3 NRA2 on sale they were already booked
of the announcement of hifido on its site, the last when I saw the announcement that more than a week it is selling, I immediately validated my purchase, since I already hifido purchased from, they confirmed the purchase
on the two sites, I did not have had business with
should I inquire about them
it may be interesting for bids yahoo auction

Hi Southpeak
thank you, for the high-end and more Japanese are reserved for the domestic market I prefer to buy directly in Japan as in Europe it is very rare as the Philippines, I take the time, day or the Japanese will understand that the surplus may bring many money and there is a strong demand from collectors of the world, prices will blaze

Hi Sandawa
   
my estimate is U.S. $ 3000 or 3000 €
is the most expensive Sansui, he has the same weight as the series 907 (xr. ...) that the I like the have in my collection as  AU-111 G  VINTAGE

I have an SA9900 hooked up right now with a pair of HPM100s. That's the pioneer integrated with macho rack handles at the back and pilot lamp around the volume dial. It may have come from the Pier but i got it from a neighborhood thrift shop and its already set to 220 volts. But then again it says 120/220 at the back. A japanese home unit that will pass through the Pier surplus stores would say 100v right?

Post by: sandawa on Oct 28, 2008 at 08:58 AM
It's good this thread has not driven up the prices of good surplus hifi in Manila, Cebu or Davao. We're very lucky to have those inexpensive Japanese vintage gear here. As Terii said, in Europe, they have to order them from Japan at high price. I've also been told the price of surplus Jap equipment in Shanghai is now way over the price of comparable brand new Chinese-made unit.

In Thailand, the price for used Jap hifi approximates that of brand new. Here's a link from a shop in Bangkok (the figures are in Thai baht): http://www.vintage-audioshop.com/product.index?lang=th

An Onkyo M-506 power amp, sold here at P5k - P8K, is being quoted at an equivalent of P25K in that shop. Kenwood 990 CDP, which is sold here at about P2K-P3K, is quoted at roughly P14K.

BTW, I got my Luxman SQ-38 last night. It was not the Signature model I was expecting. Instead, what was delivered was an FD Mark II model. I have yet to fire it up today since I had to clean its innards first. The 12 valves are complete -- 4 big ones and 8 small ones. I was told it has a problem, but that's okay, I got it for half a day's pay, anyway.

Here's how it looks:

Sir Sandawa,

Where were you able to get an M-506 power amp at 5K? I bought mine for 8K.
Title: Re: Surplus amps
Post by: sandawa on Oct 28, 2008 at 03:31 PM
I saw at least 4 units of Onkyo M-506 series sold here in Davao these past three years with price tags ranging from P5k to P6.5k. I should have bought one or two units  but the last one in mint condition I haggled for P5k -- on Narayan's behalf I think -- had a problem (power relay would activate every 5 minutes even when amp isn't hot), so I told the trader we'd pass. I was able to buy its preamp though -- P-306 -- at P1.5K. Narayan said I could keep the preamp if I like it, thus, I did not send it to him.

SX-1250
SX-950

i don't know if your tech knows it, but those transistors Dana was referring to are TO92's or the likes which tests good on the multimeter, so that unsuspecting techs can miss them. in case of crackling noises, it is expedient to just replace those with newer devices to get rid of the noise. ;D

this is not unique to Pioneer, i have encountered this problem with Sansui's and other Japanese amps.

Thanks, yes these are power triodes. I got this amp mainly for my personal collection considering I'm not very fond of tube sound. I've inquired overseas: 50CA10s are still available but at a steep price of $100 each. There's a $60 option from a Chinese firm that produces a limited number of this rare valve (baka melamine-contaminated pa!). It's out-of-stock even in Japan but there are Japanese DIYers who were able to make 25C6GAs (easily available in Japan I was told) work as replacements with modifications in the amp's settings.

A couple of days ago, I turned this monster on after removing the case and found two 50CA10s and two 6267s dead. Despite that, one channel is working but couldn't produce a loud sound without clipping. 6267s are obtainable, so, just in case I can't get those big bulbs (50CA10s are almost as big as 10-watt bulbs) I'll be happy with an SQ-38FD in mono. My uncle's 15-inch full-range EV speaker could be a good match to this.

The 25CG6A'a and its sibling the 50CG6A are pentode octals while the 6CA-10's are true power triode in a 12 pin compactron base. To use those pentodes as replacements you will have to wire them as triodes, looking at the sheets, the 25CG6A has lower screen voltage rating,if you have a link to the schematics of your Luxman, we can have a look see.The japanese tube is superior in terms of transconductance, plate resistance and power handling than the "american substitute" if we are to look at the spec sheets.

you can buy 50C6G (same filament voltage and current)for US$5 here: [url]http://www.vacuumtubes.com/price9.html[/url you can   email michael c. marx for more info.

the 6267 is very very expensive, you could probably get this new production EF86 tubes for much less...spending $100 on a single tube is way beyond my league...

the 6DT8 is more like a 12AT7 but different pin-out, or a 5670.Judging from the tubes used, i suspect that the circuit used is similar to a Mullard 5-20, just a hunch.

if you ask me, i would rather use 6550/KT88 or EL84 in triode mode, and depending on B+ even a 6L6GC/5881...if you wish to convert to trioded pentode.

BTW, replacing all electrolytics is justified since you have an old amp. it can help solve some of the clipping and lack of power issues that you are experiencing now. ;D

...i recently acquired a pair of yamaha mx2000 amp and cx2000 pre amp...


You're very lucky to have those units. They're an awesome Yamaha combination, originally sold at about $5,500/pair back in late '80s. However, depreciation is also comparatively high. Current resale value in Japan for a pair is about $1,500.

Anyway, those are high-end units by any standard. That pair should sound best on good speakers, even low efficient ones. Probably made to drive the Yamaha NSX-10000 (1987), or, the GF-1 (1991) was probably assembled for it.

i jst got very lucky... i got this amp from my japanese furniture supplier, i guess he didnt knew the value.

even i was innocent about it, until i googled it. hehe ;D i hit the jackpot.. its a treasure.

im still looking for a good speaker that would maximize the full potential of my amp,

with the jamo sat 500 it gives off a clear sound.. but the imaging is not well defined...

tnx sandawa for the info, now i knw a little bit more about this vintage :)

Post by: sandawa on Nov 12, 2008 at 08:55 AM
With that kind of amp, you need to find speakers that would cost at least $2K/pair. Or, if you want to end your hunt for speakers, I'm willing to trade my Yamaha C-6, B-6, plus NS-690III and I could throw in a Sony CDP too  ;) . Biro lang!

Seriously, if I were you, I'd find (or order from surplus importers) at least a Yamaha NS-2000 to pair with that monster amp. Another option would be the big JBL monitors -- 4430 or 4435. I have a 4430 but I'm not selling it. Buying a used 4430 from US Ebay would cost you at least $3K including insurance and freight.

POSTSCRIPT:
I failed to mention. Take good care of that pair if it's a Japan domestic model (not many of those units went out of Japan). Always check your local voltage. If it comes out 220 volts or higher, use only a 100-volt transformer. Generally, sensitive parts of rare amps are unavailable in local electronic shops.

My friendly trader was wrong again! I ordered an a607 MOS Limited similar to Terii's but what I got today is an a607 MOS Premium, which is a notch below. A used a607 MOS Limited's last transaction at Hifido was at roughly $1K. Alpha 607 MOS Premium's last transaction was about $725.

Got my a607 MOS Premium at roughly a third of its Tokyo indicative price, probably high for local standards, but I'm still happy. It has the sonic clarity of my a907 iMOS Limited but a bit lacking on deep bass. That's the difference I guess between an 18-kg. amp and 32-kg amp. Alpha 607 MOS Premium's parts are almost the same as the a907 iMOS Limited -- the brown Elna capacitors and the clean layout although disparity in size of transformers is obvious.

Here are a few photos for future owners' reference:

and tnx for the tip. but im wondering if it would be better to get an avr for this amp..

yes its japan domestic, 100 volts is needed..

im on a tight budget for the speakers.. 10 to 15k pesos is all i can shed, its my next goal,

to find a bang for the buck speakers for my setup.. :)
 
the amp is well maintained indeed.. few minor scratches only. vu meter working great,

overall the amp is in pristine condition.. it also goes with the preamp..

tnx southpeak for the info. il try it next time i post..

il keep a copy of the of your post as a kodigo. hehe.. :)

tnx guys for thi info.

Title: Re: Surplus amps
Post by: sandawa on Nov 13, 2008 at 07:22 AM
Yamaha MX-2000 has a lot of reserve power to provide you with deep clean bass. Your amp would surely drive small speakers happy but you should hear first how it performs when paired with heavyweight Yamaha speakers that are available from the used market there in Metro Manila.

A P15K budget would be enough for a Yamaha NS-1000M (P8K to P10K - original price: 250,000 yen/pair) and a 750-watt 100-volt transformer (P2K). The second option is an NS-690 series (P5K to P7K - original price: 160,000 yen/pair). Both NS-1000M and NS-690 have 12-inch woofers that could faithfully reproduce low notes. If you post "Looking For" those speakers in the buy-and-sell section of this forum, I would not be surprised if your get reasonable offers.

I'm just kidding about swapping my Yamaha C-6, B-6 combo  ;). The 200wpc pyramid-shaped B-6 is a rare piece and produced in limited number due to a lawsuit threat Yamaha received from Bob Carver. I don't think I could find another pair of those collectibles in this country. But I could let go of my NS-690III. The problem is I'm based in Davao and a pair of 690III weighs over 50 kgs. I'd rather keep it here, no hassle, unless someone wants to pick it up at the right price from my place.

Rene,

Ang maganda dito sa MOS Premium, merong jack for a separate power amp with front panel control. All you have to do is turn a knob if you're not happy with the built-in power amp section. Kaya heto, naghihintay ng konting lakas para ibaba yung isang mabigat na Denon POA-1001 to provide the second option for this new toy.

I'm excited again! BTW, may tatlo pang alpha 607 dito sa kaibigan ko: a607i, a607XR, at a607 Extra. Also a Technics/Panasonic THX amp (SU-TX50) with 480 watts power consumption -- katulad na nung 1/2 HP aircon ang konsumo. Tapos meron pang padating na Onkyo Integra 919, which could put out 420 watts per channel at 2 ohms. Ang masakit lang, medyo nagtaas by an average of 50% ang presyo ng Jap hifi dito. Pero at least may dumadating na good-quality gear.

Wow sir Sandawa you have a very nice amp there. Congratulations. Hirap na maghanap ng ganyan dito ngayon. I had a chance to get a 607nra (gold) before, but choose a 907 limited just wondering if a made the right decision :) mali yata
Title: Re: Surplus amps
Post by: sandawa on Nov 14, 2008 at 09:12 PM
You mean you have an Alpha 907 Limited (Approximate Current Resale Value: $1,500)? That's the second best integrated amp in the Alpha series built by Sansui. The Alpha 607NRA is more like a model in the regular line -- not a special one. If what you got is an AU-D907 Limited (ACRV: $300 to $900), I think that's still better than Alpha 607 NRA (ACRV: $400).
Title: Re: Surplus amps
Post by: blue_123 on Nov 14, 2008 at 11:57 PM
It's just the au-d907 limited. not the top of the line model. makinis din kasi yung 607nra really had a hard time choosing at that time. Thanks for the input sir  :)
Title: Re: Surplus amps
Post by: sandawa on Nov 15, 2008 at 06:52 AM
You're wise enough to choose AU-D907 Limited over a607NRA. However, the newer a607NRA II would be almost at parity with D907 Limited, in my opinion.

If you check Hifido's recent transactions on AU-D907 Limited, the current indicative price has climbed from 35,000 yen to 98,000 yen. As I've noted in previous years, the increasing demand from European audiophiles and international hifi collectors for upscale made-for-Japan Sansui amps would drive prices of these items way up.

High resale value of an amp reflects increasing demand for it, indicating further that such item has attributes that the market generally prefers over comparable units.

Look here:

Hi Sandawa
   
congratulation for 607 mos premium on the lack of bass, I think the transformer is involved, the transformer of 607 mos limited weighs 11kg him on the 607 nra2 the sound is almost identical to mos limited but the difference it is the bass that are present, it confirms what I read on forums on the Japanese nra
now I use them in biamp horizental:
607 mos  limited   to high  pass infinity renaissance 90
607 nra2  to  low pass infinity renaissance90
very nice soundstage

It's probably better if you can visit me next year since I lack patience in shipping these heavyweights. Manila to Davao is a lot closer than Manila to Russia where your work is in. Instead of giving some of these to my importer-friend's technician, I'll keep them for you. I understand your interest in these equipment, even the basic parts -- from caps to chokes -- are really premium-type compared with those loaded in British or American hifi units.

Hi
I would say that some units that are not exported ,are interesting to discover, buy me directly
in Japan of units that are not exported
in Europe, many people are reluctant to buy directly in Japan because the voltage is 100volts, they think voltage transformer degrades the qualities of sound units (230v to100v) ;D

There are two alpha 607s in the pier now.

The better unit seems to be the alpha 607 extra.

The past week, i saw Sansui aux1 at the pier.
I didn't know what it was so i went home. Later i checked it out on google and saw that it is claimed to be one of the best amps made by sansui. Also that it has helped gain for Sansui the sobriquet, "sansunog". The stability problems of the model seems have to been corrected in later released.
But of course when i went back yesterday the unit was gone. Gone also was the pioneer sa9800 i saw there sometime ago.

There was an onkyo m509 being repaired at the store.
This model has those whopping large vu meters that crowds everything out in the amp front and stares you right in the face.
Lighted, these meters must glow like hell in a darkened room. Of course the seller already has committed the unit to somebody else.

I also listed a Sony TAf650ESd... (i was attracted by the ES model. However i couldnt find anything about this model.)


Title: Re: Surplus amps
Post by: sandawa on Dec 02, 2008 at 03:26 PM
I wonder how's pricing of those units there now. Regular Alpha 607s here in Davao are now quoted as high as P6K, from as low as P3.5K in previous years (Japan used price $200-400). I got my 607 Mos Premium limited edition (160 watts power consumption at the back) at P9K (Japan used price $600-700). My AU-XII (used price $600-800) was bought at P8K four years ago, so the AU-X1 should be within that range, probably higher now.

The past week, i saw Sansui aux1 at the pier.
I didn't know what it was so i went home. Later i checked it out on google and saw that it is claimed to be one of the best amps made by sansui. Also that it has helped gain for Sansui the sobriquet, "sansunog". The stability problems of the model seems have to been corrected in later released.

yes, i remember i repaired one unit sometime in the early 90's...and yes it kept blowing output transistors...so the fix i did was to modify the circuit so that is used less parts....the circuit is fully complimentary push-pull from input to output...i simplified the circuit to look like a Leach amp..... :)

That's a good one. The biggest Onkyo power amp that arrived here in Davao was a defective M-508. It's possible the M-510 Grand Integra would be coming soon. 

sandawa,

i am interested in the defective M509, i would like to have it as long as all major parts are intact...thanks.. :)

Nelson,

I think that's close to a perfect match. I have a P-306 and I'm impressed with its performance. The tone controls, if you're the type who needs these, have wider range compared with other preamps. Even the phono section is quite good. The P-306R should come out better.

Tony,

No, I did not get the defective M508. But wait, I just smoked my AU-X11 last night since I was experimenting with its external connectors -- 2 external preamps, 2 external power amps could be connected to it -- and in my excitement I plugged it in a 220-watt hole. It's been with me without problem for about 5 years now and has been an anchor in one of my major systems. If my technician can't fix it, you can take it away next year -- but beware, it shows 32 kgs. on my bathroom scale.

Sir Sandawa,

Thanks for the reply.
I might as well grab that matching preamp.
Time to shell out some more. :'( :)

Btw, i hope your AU-X11 be fixed in no time,
it is one of Sansui's best.
At 32kg, it's even heavier than the M-509! :o
Goodluck Sir, keep us posted on the development.

Sorry, it's actually 28 kgs. based on audio heritage site but my scale showed 30 kgs., I think my weighing scale is defective.

I took the opportunity to open the AU-XII which I failed to do in the past since it's too heavy and set up tightly in a rack (too big -- 21X17X8 -- taller, wider and deeper than normal amps). Here are some of the photos taken a few minutes back which could serve as reference for those who might have a chance to find a unit adrift on Manila Bay one of these days:

depending on how long it was soaked at 220, i doubt the traffo's fried, there should be fuses to protect them...otoh...
now you have a chance to do the next best thing, which is to convert this amp finally to a 220 volt amp...torroids are available with 220volt primaries...looks to me there is a separate psu for the front end as well...i am trying to locate schematics...torroids can be ordered at rs philippines....

look out for bulging electrolytics...on the right-hand pcb of the last picture...there looks like one bulging cap.....i could be wrong...i am used to looking at bulging caps on motherboards.... ;D

Tony,

It took just a few seconds but I could hear one pop and saw some smoke. I believe the transformers are okay -- yes there are two. I just brought it to my technician an hour ago and he said it's likely some caps and smaller parts, hoping the damage did not reach the transistors. The technician has been repairing Jap domestic amps on a daily basis for at least 10 years now -- he's employed by the biggest Jap hifi importer here in Davao -- so, I'm quite confident with his ability. Unfortunately, he's almost illiterate when it comes to valve amps.

Ivann,

If the price of my a607MOS Premium would be used as gauge, an a607NRAII (the last of the a607 amps produced -- 1999 -- before Sansui went under) could be quoted from P6K to P8K by surplus Jap hifi dealers here in Davao. That would likely be the quotes from Manila's Pier dealers. In Europe and the US, hifi enthusiasts are willing to buy those gems way over Japan prices, which could be close to $1,000 per unit.

 Integra's power amps with large VU meters. Yesterday, got my opportunity
 and i can't let the rare chance slip away....
 Yes, it is the Onkyo Integra M-509....
 Been using  it the whole day and it runs smoothly with no hint of any
 problem whatsoever.
 The sound is full, warm, balanced and controlled even in high volume.
 It's well worth the loooong wait.
 Grab one guys! ;)

I wonder how's pricing of those units there now. Regular Alpha 607s here in Davao are now quoted as high as P6K, from as low as P3.5K in previous years (Japan used price $200-400). I got my 607 Mos Premium limited edition (160 watts power consumption at the back) at P9K (Japan used price $600-700). My AU-XII (used price $600-800) was bought at P8K four years ago, so the AU-X1 should be within that range, probably higher now.

I'm a lucky guy. I brought the AU-XII to the technician 11 a.m. yesterday but he apologized he would not be able to attend to it immediately since he still has to fix an electronic organ used by a local band. So, I said no hurry. But I need a feedback before I leave for Manila in two weeks so I could look for parts in Raon if necessary.

What do you know, I just got a text saying my AU-XII has been singing perfectly for two hours and ready for pick up. Repair charge quoted was P450 (less than $10 for foreign audio enthusiasts monitoring this thread), but I intend to give him P1K ($20).

BTW, he was telling me yesterday he has accumulated a stash of rare parts for upscale Japanese solid state amps. But he said he's not selling any, merely hedging for personal use and for future repairs. I believe him since he's the amp specialist for the biggest importer of Japanese hifi here in Davao.

Thanks, problem is I bought two extension cords from CDR-King (P180 each?) last week, one I hooked to a 1,500-watt 100V transformer and another to 220V line in my living room. I forgot to put labels and accidentally plugged the AU-XII to the 220V line the other night. Then, "pop" it goes with white smoke coming out of the back grill. The smell was almost unbearable. Anyway it took just a couple of seconds since I was able to switch off the extension cord immediately.

Wala pa akong nakikitang ganyan dito pero pag may naligaw, titimbreahn kita. Kadalasan ang nakakarating dito yung P306, /R, /RS lang. Pero mura ang bigay dito ng preamp between P1.5K to P2.5K lang depende sa condition. Pinakamahal ko nang nabili dito Denon PRA 2000 @ P2.5K, pero resale price nito sa Hifido pumapalo pa ng 100,000 yen. All the others were bought from P1.5K to P2k.

Don,

Totoo yang sinabi mo at mabuti binanggit mo yan. Napaka importante sa hifi collectors na may trusted technician. Sa dami ng vintage gear ko na pwedeng masira, kailangan ko ng reliable technical support. Kahit personal problem nito tinutulungan ko at so far, hindi naman uma-abuso. Kung minsan kasi yung maliit na halaga lang sa atin, napakalaking bagay na sa iba.

we had the same problem in our plant before where we had this assortment of 220 and 110volts equipments...accidents did happen very often.........so we came up with the following solutions. :)

1. installed 120/130 volt mov's after the fuse on equipment rated for 110 volts.
2. replaced the outlets and plugs for 110 volt equipment to a different type so that plugging in equipment on a wrong voltage is not possible.

this is applicable on the home setting also...

Good thing you mentioned this since this is an effective solution for those with a lot of Jap hifi equipment. Actually, I grew up with dual 220/110v outlets in Manila and also had it installed here in Davao (in my home which is 8 kms away from central business district). However, I now live in a rented apartment downtown and that's the problem. No 110v outlets.

The way we did it at home was 220v pairs of flat holes on the left and right sides of the plate and a pair of round holes for the outlet in between. That way, no chance of costly mistakes since all 200v appliances would have flat prongs and 110v would have round prongs. I'll probably install external tubes for 110v outlets in the next few days. Or, I'll spray red paint on all my 100v extension cords just to make sure I won't repeat the same mistake.

sorry for the OT....what happened there was that you smoked the MOV's inside the PSU....MOV's are installed in shunt each with the two main filter caps, it was designed that way so that in case of such accidents, there would be smaller bang, the mov's are small and fries as an open circuit as opposed to other semicons which fries as a short in most cases...

so the next time that scenario happens in that psu, expect a louder bang!!!!

But! but! The widow won't let go of it for "sentimental reasons"!
It is complete with its matching tuner, tape deck, open reel tape deck, turntable,

We've offered monetary considerations, but to no avail....

Hi Tony,

Indeed, the Pioneer Spec 1 and Spec 2 are awesome pre power amp combination.

to the proud owner of the onkyo m509... congrats..
Was that your group waiting while a technician was soldering something in the amp? Maybe not. i think the group i saw at the store was trying to convince the seller to sell the amp to them but the seller stuck to his guns saying that he is already talking to somebody. i may be wrong though.

But that that amp is an eyecatcher.... those meters really looks so MACHO!!!

Sir Sandawa... congrats thin on the successful repair of your auxii.

and YES.. those SPECS 1, 2, 3 AND 4 are amps to die for. :)
I wonder... was the owner a member of PinoyDVD? You have to try and visit widow again and again. lol... sabi nga nila...walang matimtimang birhen sa matiyagang manalangin...

 Thank you Sir Lord Foo,

 Yes it was us waiting for the M-509 to be fixed, luckily the problem was just the relay. The seller gave the amp
to us for the reason that the original buyer was not responding to his messages and calls.
Been using it everyday since, the amp works flawlessly, thank God!
Yes, the huge VU meters are fantastic!

 About the Specs, the owner was not a member of PDVD...
It was bought brand new during the Specs heydey! Btw, it is housed in original
Pioneer rack complete with its matching audio equipment!
It was just sleeping there for years now.

Yes bro, I seen your Onkyo pre amp including your M509. Yup those speakers had been there for quite sometime now, not sure if its a denon or a sony.

What I got, dont know if you've seen it when you went there, are the Huge Yamaha Vintage Speakers.

 Hi Bro,

 Yes! yes! Those vintage Yamaha speakers! I've seen it the day i bought the M-509.
 But when i return for the pre amp, it was very noticeably missing!
 Those are indeed vintage looking, i must admit, i was tempted to have it tested, but,
 even if it impresses me, i don't have the space for it. As it is indeed huge!

Those are just too big of an enclosure for a midrange.

Hi 2 all fellow PDVD members! Bago lang po ako d2 and this is my 1st post......

Meron po kasi ako Sansui Au-D607 na nabli ko last september. 

Last week nagprorotect yung relay tapos blinking lang yung ilaw tapos nagkaroon yung right channel ng popping sound, ano po kaya may problema?

Mga Masters, HELLLLLLLLP naman po.....TY
Title: Re: Surplus amps

 Hi Sansutsut,

 That is a good Sansui, in fact i have one.
Bring it to a good electronic technician,
before something of a major problem may occur.
 That is a dual power supply Sansui model amp,
AU-D607, 70wpc.
 My main concern when buying for an amp are the
output transistors.
 Sansui usually uses Sanken or Toshiba.
Those transistors are hard to find nowadays, worst,
not available anymore.

Sir, how about yung ang tagal bago pumalo ng relay and yung output sound ng right ay mas malakas kaysa output ng left? Possible kaya sa mga leaky capacitors?

Siguro nga po tama kayo dalahin ko sa good electronic technician!

Post by: Nelson O on Dec 13, 2008 at 11:21 AM

Sansui amps takes few seconds for the relay to activate, this is normal.
It should be about 5 secs. Longer than that, there might be a problem somewhere.
Well regarding the output sound, AU-D607 has a selector switch at the back, that
contact point may became dirty over time (preamp-power amp sel. switch) and may result
to problem to the output sound, Try cleaning it with a contact cleaner.

Sir Nelson O,

My AU-D607 activated the relay mga 30seconds
to 1 minute.Nakita ko po yung sinasabi nyo na
switch at the back of my amp, pwede po pala
maging separate power amp and separate pre amp?
Wala po ba talagang jumper wire betwen
pre-amp out and power amp in sa rca at the
back, kasi po sa ibang amp na nakikita ko
ay meron.

Ty po ng marami ulit...... ;)
Title: Re: Surplus amps
Post by: Nelson O on Dec 13, 2008 at 04:22 PM

 
 Yes, AU-D607 can be used as an integrated, pre
 amplifier or power amplifier by properly setting the
 selector switch at the back, the reason for not having
 a jumper wire.

 Thanks Sansutsut,

 Yes, i'm the lucky (am i? hehehe...) owner of the all intact,
all original power output transistors (all Sankens) M-509.
It's a 200wpc at 8 ohms power amplifier and weighs 31kg.
My heaviest amp being the 9090db (24kg) before having the
M-509. You should see the vu meters in action! Fantastic!
Btw, about the fuse lamp. I think Raon is the best place to look
for those vintage electronic parts.

 Ah, ok, you're referring to FJMR.
 IMHO, every AU alpha regardless of the model
 are well designed.

wala po sir, dun din po sa FJMR yun.
audition ko lang pati yung Alpha na 607,
sa 507xr medyo ok yung pandinig ko.
pero sabi naka reserve na daw ung 507xr.
May nkapila pa nga po sa akin na
mag aaudition din sa mga Sansui's...hehehehe

Hello po!.. merry xmas to all!!

I'd purchased 1 unit of PA for my audio setup. This was been made by Victor japan (110VAC from pier) and model is M-1100. I would like to ask a favor from anyone if you have any idea/s regarding this amp? I am also asking if anybody here has keeping a specs/diagram for this type of amp.. As I opened the console, it was been driven by a 7-pin power pack IC (STK-00125 product code). I tried to search on google & yahoo but this was not been displayed even the datasheet for this IC does not display also.

Need everybody's help.. thanks for the support!!

hi all i would just like to ask something about the speaker terminals of most of our vintage amps. i tried using a bannana plug kaso di sya kasya. what are the other alternatives of connecting ur speaker wire aside from using barewire

btw my terminals look like this

My dilemma also. There are protrusions around the binding posts and no contacts for spade lugs, while standard banana plugs are too loose at the rear holes of the posts. Very time-consuming having to pull out the wires from spade/banana plugs and thread the bare wires when you want to change amps. I hope our gurus here have some solutions :).

Post by: Reymer on Dec 26, 2008 at 04:31 PM
Unless you are willing to replace the speaker terminals, I think there's no other way but to use bare wire :(. All my vintage amps do not accept banana plugs or spade lugs either.

Title: Re: Surplus amps
Post by: sandawa on Dec 26, 2008 at 08:14 PM
Kung may butas yung speaker connector terminals, para talaga sa pin-type. Kung walang butas, pang bare wire siya. But if you want to use pin, magpuputol ka. No problem for Monster Cable pins dahil malambot, madaling mabali pero mas matibay gamitin for the old speaker terminals pag maikli na siya, kung hindi ka naghihinayang putulin kasi may gold content daw yun kaya daw easy to break (ewan ko lang!). Yung Quantum may malambot at may matigas, talagang bakal na gold-plated, kung minsan mahirap baliin parang mga mumurahin na pins. Unlike the cheap pins, the branded ones are connected line banana plugs, meron ding butas at screw to accommodate various wire sizes, so madali rin magtanggal.

I wish I could post photos of some of my hooked vintage amps using long (mostly Yamaha power amps) and short pins (old Accuphase, Sansuis and Luxmans) kaya lang nasa Maynila ako ngayon.

if you dont want to tamper your amp or want it preserve for possible future resell,
what you can do is to make a temporary adaptor connector temporarily fixed to  the amp.
Buy the speaker connector that you prefer accdg to your need.
Solder a short pair of speaker wires to your preferred connector (at the back preferably) and then the other ends stripped of bare wire (these you connect to your amp's original speaker connector 'semi-permanently for the time being youre enjoying your amp...).Insulate the expose soldered metal part of your connector to avoid touching the bare amp chassis.Try to temporarily, fix this adaptor jig via wire wrap or equivalent  using chassis holes/screws as 'anchor'.
If you plan to resell in the future, just remove this temp jig speaker connector preserving your amp in its orig condition...(buyers usually prefer stock condition...)
sorry guys, no pictures (too busy these holidays...)...just use your imagination based on what i described above.

You really feel it kung naka swerte ka. It happened again to me last Thursday at MCS.
Was just passing by looking for cd/dvd and went in this store at basement. Naka lapag sa isang tabi, naka balot ng plastic, got curious and saw it was a Marantz PM-84D in pristine condition, parang NOS  :o. from a collector also sabi ni Richard (you know him) but does not want to tell me who or if owner is a member of this forum. Any ways, isang tawaran lang sa tex, tapos ang boxing..
To the previous owner, sir if you are a member, please send me PM. I would like to thank you personally.
Thank you sir. NOS looking na   8), NOS sounding pa  :o. and best of all, at PIER price pa!!!! :-* parang pang HiFi-Do

May nabili po ako last week na Yamaha AV Receiver.

DSP-AX520 @ Php6,000

Im sure napamahal ako, hehehehe

No remote po, so most likely, I will have to search for a universal remote.

Any ideas po kung anung brand? I see a lot of CDR-King remotes na universal pwede na kaya?

Also, plano ko po sumali sa mga masters dito na mahilig mag scour ng vintage amps at preamps.

Sana po you could post a link of must buy items and models para in case makita ko i can post here if its available so that di tayo mawalan ng info.

you can try hifido and vintage knob to check out which vintage amps are valuable there are several websites naman for you to check the value of an amp

for the remote control you can try out the cdr king remotes basta compatible (its worth a try for P120 you cant go wrong) however malamang limited lang ang controls na magagamit mo like volume etc...

Tnx masters

usually a preamp would have output plugs (rca left and right labelled as out). you connect this to the power amps input. If kakabit mo sa AV reciever dapat may preout yung av reciever mo to be able to do this. note there might be some compatibility issues considering ur av reciever is 5.1 channel while your power amp is 2 channel lang so technically 2 channel lang mapopower ng power amp mo

Anyone here knows the owner of the Denon PMA-1000 left in one of hte shops in MCS? Already forgot which one as I hurried out after listening to it for about 15mins, had to pick up my gf at the SolGen's. There were scratches on the top plate and a chip on the back of the left wood panel, I was hoping I could negotiate for a lower price. Thing is they already lost track of the owner, and it's been sitting in there for around 2 years.


Was hoping to get it for 5k so I could have the scratches painted over and wood panels replaced. good old Class A power, would have grabbed it already if it was in better aesthetic condition, although the front panel's nearly faultless.

NO!!! In my experience no sir.

Get a 100 v transformer for 100v jap units. In the long run your 100v units will get busted if powered from a 110 stepdown transformer. Not immediately; but in time.

However, my sansui amplifier when i used a 110v transforme goes into protect mode when it gets strong bass signals from the CD Player. The protect pilot lamp indicator starts blinking. All audio cuts off. Then after a while the lights stops blinking again and the amp goes live again. Then it drops off again when bass signal is received.

I shifted to a 100v stepdown i got from the Pier. (please get the larger units not the smaller units. they cost a bit more though) and the amp never had problems again.

I presume that that will be the same problem with a 100 v CD player plugged into a 110 v transformer.

i hope this helps

Medyo general ung question sir. You need to mention brands and models here. I myself have not purchased any raon amp being partial to either vintage amps or the newer home theatre amps.

Can I assume that you are referring to the New China HT amps in raon?

HMMMM. this is out of topic pala noh? Still

However my brother have been buying amps in raon and have done some research on them. He says there are so so china amps and there are a few great new china amps also.

To illustrate, one of the first 5.1 amp he bought as a newbie did not make him happy after a while. He opened it up and lo and behold... the rear or surround speakers were connected directly to the source for the front speakers...andaya...grabe. What a horrendous gimmick!!!! This will probably scare you off but it is gruesomely true.

After that...my brother did some searches in this forum, sent some email inquiries and was adviced by some guru about the good models...(i forgot which).. The model even had option for upgrading to double the output and kaya pa rin ng power source... i will txt him re the model and brand and post later. I remember it has cooling fans and the top has a transparent cover. He now has two of them. Bought upgraded with some parts he also bought from Raon. He uses one them to power some Vintage JUBAL JBL speakers ins office and a 5.1 set up at home.

In short sir...you need to know what brand/models are the best over there. Maybe some of the gurus here can pipe in and identify those yummy ones...

in some cases you can get away with it, i did.....but why take the risk? ;D

cd players use  very small transformers, and at times there is plenty of space inside so that you can just get a 110/220 small traffo and use it as an auto-trafo......or....

you can have that traffo converted to 220 volt primary...wouldn't cost you much...and the conversion can be done in raon, "while you wait".....there are lots of transformer rewinders along the streets of raon.....

Medyo OT tayo since this is a surplus amp thread but I have actually asked a technician to change the transformer of my Victor CDP from 100V to 220V and I was surprised it took him only less than an hour to do it. What he did was buy a transformer with various voltage taps as replacement to the original one.

There's a minor problem though. After, say, two hours and you go close to the CDP, you'll hear a slight hum coming from the transformer. It's not heard on the music/speaker though. I could live with this minor fault since there's no hum after an hour even if I get my ears close to the CDP's cover. I'm using my converted CDP for over a year now.

LordFoo,

Good to hear from you again. We miss you in a thread opened by Southpeak on vintage hifi. I didn't realize there are so many of us here who are into collecting surplus amps.

Yes, I was only charged P350 for everything. I was told the transformer used costs only P250. I checked out how it was done and realized it was really simple since even the 100V transformer's taps have labels which could be the basis in connecting the wires when the 220V transformer is installed.

If only the technician used a more expensive transformer, maybe the hum would not occur when it gets hot.

word of caution to those who have their transformers converted: make sure the replacement transformers produce the same secondary voltage and current as the originals. some unscrupulous techs replace only with the nearest value, say 9 or 12 volts for a 10 volt secondary. that would be synonymous to using a 90 or 120 volt supply to your 100 volt equipment.

Oops, this gets me a  bit confused. I'm not a technician, just a hifi enthusiast willing to learn from those properly trained in this field. I don't understand why the output on 100v transformer becomes relevant again after conversion.

What if I do this:

1. Remove the old 100v transformer and put voltage labels -- say, 6v, 9v and 12v -- on the wires cut using the transformer tap values as basis.

2. I plug in the replacement 220v transformer (same same size and wattage) and test if the corresponding taps -- 6v, 9v, 12v -- produce accurate values. I'd probably do it immediately after plugging and after 2 hours to see and hear if the voltages vary or the transformer hums when it gets hot.

3. If I get the desired results, I install the new 220v transformer in my equipment.

My question is, would there be a problem with that?

It's that simple to me but I could be wrong. BTW, this is not OT since this could apply to smaller surplus 100v amps where conversion cost could be practical.

your plan is sound......go for it... ;D

the object of voltage conversion is to get rid of that 100 volt primary coil and be able to just plug into the wall....

i have done lots of voltage conversions in the past....

there are many ways of doing it and what step to take depends on a case by case basis...

1. if there is room inside the unit itself, merely adding a small transformer with 220/110 volt primary and using just the primary as an auto transformer feeding the 100volt original transformer from the 110volt tap is enough.....now do not worry much if that is a 110volt tap feeding a 100 volt primary.....there is enough impedance to limit current so that the 10 volt difference amounts to nothing.

2. there are cases wherein the transformer is designed so that the primary coil and secondary coils are built as separate(independent of each other) units on the transformer core such that you can dismantle the coils (and not disturb the secondary coils,) and just work on the primary coils to convert to 220.....i have done a lot of this, this is the best conversion if you ask me.....though requires more work....

... a non-issue in conversion ... provided of course, its not in the magnitude of probably 20% or more! But still will not guarantee exactly 10V with your gear if plugged in your wall outlet.

The truth is that you are lucky enough if you can get 220Vac right at your wall outlet ... and if you are using 220-110 transformer, it might be possible that you will just end up with the desired 100V!   


If you are nearby a utility transformer, chances are, you are getting a generous supply as much as 240V.... and that even if you use a 220V-100Vac in this situation will still push the 110V to your equipment. That 100Vac rating on your transformer will be reduced to just letters!   


If you are really paranoid to have your equipment suck 100V, then use decent AVR that has 100V output - the servo-control one works great .


Typical operations of an electrical gear is +/- 10% of plate voltage

its just 15wpc but when i heard it yesterday, anakng*&%$! it drove my b&w602s2 with ease and the sound- vintage malapad,fullbodied,lush tube-like! talo ang luxman r3045 ko! unfortunately the unit offered was really old,"gusgusin", tuner had problem with the dial tho fully functioning and, partida- installed was a a cheap china-powercap so i declined. kung marunong at matyaga lang ako mag-restore at magpalit ng cap (an elna 33000uf was included as replacement), baka di ko na pinalampas. so if any of you happen to see this or an sx780, dont be fooled with its light weight - 9kg and 15wpc power.

Just to share a similar observation. Three of my amps are now in my wife's Las Pinas home: Musical Fidelity A-120 (40wpc of pure class A); A&R Cambridge (or Arcam) Alpha 6 (50wpc) and a Pioneer SA-710 (20wpc). The MF-A120 is of course a different breed, but between the 20-watt Pioneer SA-710 and the Arcam Alpha 6, the Pioneer SA-710 is significantly superior. And to think that the Arcam Alpha 6 is British high current design than puts out 100wpc @ 4 ohms.

The SA-710 (1973) also beats the Pioneer A-UK3 (1993) which is equivalent to the much hyped Pioneer A-400 (30wpc) designed by John Bamford, a British audio engineer working for Pioneer's UK subsidiary. My take on this is if the "legendary" Pioneer A-400 is really that good as UK publications reported in the early '90s, how come it failed to be appreciated by the hifi market outside UK? BTW, A-UK3's (A-400) typical resale price in the Japanese used market is only 6,000 yen. In comparison the SA-710, despite being 20 years older, is still quoted at 10,000 yen.

i also had the pioneer uk3 and it pales in comparison to the sx770. iba talaga ang 60s 70s vintage gears, many sounds tubey! sana maayos at "mapaliguan" yung sx770 at babalikan ko ;D

so, sir ahobbit; for an ordinary user with no technical or engineering background, no tools and gadgets; may i ask whats the best to use with japanese surplus gears?

for quite some time, ive been using stac avr with my jap. surplus gears and had no problems.

tnx

I mentioned it na, and tony confirmed it ...

a decent avr with 100V output is a sure way of getting 100V no matter what's your wall outlet rating +/- of 220V range ... pag 220V lang output mo sa AVR, then get a transformer with 100V output and plug it into your AVR to ensure a steady 220V comes into your transformer and out a steady 100V

sir! di ko tinantanan yung pioneer sx770 na gusgusin.
tama yung mga taga AK > http://www.audiokarma.org/forums/showthread.php?t=113874

ang ganda tumunog ni bulilit! ewan ko kung ano ang binudbod na betsin nung hapon na gumawa neto pero nakakamangha, 15wpc ang liit ng transformer, iisa ang power cap (china replacement pa, may elna cap ako dito pamalit). ok 220volts na ito at ang sorpresa - may preamp out na, may center channel out pa! kinabit ko sa subwoofer yung center channel gumana subwoofer hehehe

now the challenge- "paliguan" ang sx770!  ;D

nga pala meron pang isa inooffer sakin pioneer tube receiver using 6bm8 power tubes, di ko makita info sa net nung model s45x yata nakatatak sa likod....abangan!

you can replace the electrolytic caps in the power amp sectioon, it's been a long time, your amp can use new and fresh caps.....

thanks! thats just what i had in mind. im just curious sir tonyt, theres only one "big" cap beside the smallish transformer in this amp. right now, a replacement chinese-made cap is in place tho i have a 2200uf/50v and 3300uf 50v elnas. the 2200uf fits the hole for the original cap...

can i have a copy of the manual? i'll pm you my email addr if you have time to have it scanned and sent. TIA

if it was done before, im sure it can be done again! like movie remakes. the younger generation of audiophiles might want a taste of the "glory of the past" and compare it with present day amps. baka mabaligtad ang pananaw nila sa audio hobby! (like that guy in audiokarma.org link i posted)

quote from AK member doodz66 - I just got a mint condition SX 770 for $40 and it sounds incredible. I am hearing things on cd's that I have played forever for the first time. The soundstaging is awesome. I hooked it up to my system in place of my $1400 Linn Majik and now I am reevaluating what I think about audio. I love the classic stuff, but I can't believe that it makes me happier than the Linn. I wish someone could explain it..."

yes, the good ole days when the schematic diagram is included in the brochure/manual. eh ngayon yung iba di mailakip ang schematics; ewan kung nagttpid o baka naman delicate, baka magka.aberya? ::)

not quite the same sir. the ca-r1 doesnt have classA operation and it might not even be "vintage" yet if the ff: translation is accurate. the speaker terminals are pushbutton type not the typical screwtype thats common to many vintage stuff.

i havent listened to it hooked up with cdp. i used the pioneer sx770 as tuner for easy listening last night. malambing not too fullbodied/lush; good details and soundstage.

CA-V1 is from c. '78/79, part of "lower" lineups and (seemingly) not distributed much ; CA-T1 is the tuner that goes with it.

Yam' at that time had some fairly similar lineups which still are little mysteries to me and rarities anyway:
CA-V1,
CA-X1,
CA-S1,
CA-R1,
CA-G1...
...all integrated amps with often a dedicated tuner alongside (seemingly), and the "R" and "X" units being (seemingly) nearer the regular units (CA-2000 etc)... Currently hunting some lit' on all of these but no luck so far...

Those models are indeed 'mysteries' but not really rarities -- a lot of them drifted here in Davao since late '90s. The Russian hifi sites also showcase many of them.

BTW, the technician who just repaired my Sansui alpha 907 told me a problematic line in the Yamaha series is the magnetic type such as the B6 and the B70 power amps that were based on Robert Carver's (Phase Linear, Carver, and Sunfire) design. These came out in late '70s and early '80s. These are lightweight amps with high RMS ratings. For instance the B6 weighs only 9 kgs. but rated 200wpc at 8 ohms. I'm lucky my B6 is A-ok, otherwise it could be headed for the dumps.

Yes, what we call here as 'Surplus' hifi is expensive/upscale hifi to them. The Chinese are paying more for Japanese vintage than new 'boutique' type hifi that they produce. If you look at their hifi trading sites, their prices for vintage Jap hifi are way over Tokyo's used hifi prices.

A couple of years ago, a Vietnamese vintage hifi enthusiast sent me an email inquiring about my gear since he also has a similar collection. I later found out he's a high-ranking government official. Meron din taga Bangladesh who's an official of an international development agency who has communicated with me in the past on amplifiers similar to what we own.

nani,

so, do you think the days of "pier surplus" are numbered?  ::) (i heard fewer good quality surplus units are coming in)

update on the "pioneer s45x" - i tested it awhile ago and grabe ang ganda! taob ang amxel34/bom tube preamp combo sa bass and lower mids in driving my bw602s2 and ribbon planars (sans subwoofer pa!) tho taob sa upper mids and HF, medyo laidback. it uses 6bm8 power pentod and triode combi tubes (partida trigon lang ang nakakabit)...

only problem  is it isnt really a pioneer. ;D although the marking inside front panel glass is s45x, research showed it really is an Allied 333 /pioneer sx34. there are pioneer logos on some parts (those square alum parts on the right hand side of the unit). another thing is the tuner - tuned to japanes fm so 3channels only

as much as i'm enamoured by the sound quality, i didnt get it.

Rene,

Pier's vintage hifi glory days were over for at least two years now. High-income Americans and Europeans are buying straight from Hifido and other online sources. The English guy who talked to me over the phone from HK two years ago was a lawyer for Lloyd's. Instead of going home straight to London, he traveled to Tokyo just to buy a Sansui a907 amplifier whose used price could go over 200,000 yen for premium models. 

Rich Chinese, Thais and Vietnamese are buying from their traders vintage Japan gear at higher than Tokyo prices. Kaya dun na pumunta yung magaganda. Sa atin yung dumadating kung meron pa, mahinang klase, laspag na ang faceplate or cover, at faulty units -- difficult to recycle. Sa madaling salita, true hifi junks na.

Rene,

Pier's vintage hifi glory days were over for at least two years now. High-income Americans and Europeans are buying straight from Hifido and other online sources. The English guy who talked to me over the phone from HK two years ago was a lawyer for Lloyd's. Instead of going home straight to London, he traveled to Tokyo just to buy a Sansui a907 amplifier whose used price could go over 200,000 yen for premium models. 

Rich Chinese, Thais and Vietnamese are buying from their traders vintage Japan gear at higher than Tokyo prices. Kaya dun na pumunta yung magaganda. Sa atin yung dumadating kung meron pa, mahinang klase, laspag na ang faceplate or cover, at faulty units -- difficult to recycle. Sa madaling salita, true hifi junks na. Kaya kapag merong dumating na maganda, kahit mahal, kuha na -- parang yung Sansui a607 MOS Premium (45wpc) ko at P9K. Medyo masama ang loob ko dun, kasi yung presyong yun dati a907 series na.

kabibitaw ko lang ng sansui au9500 huhuhu. pero ok lang i know it will be soon in the good hands of sir mardoc, who i heard is also an audio hobbyist and an avid collector of audiophile gears.

For several years now, some posters in this thread have been asking me through PM for amp units I'm selling. For the Nth time, I'm not selling any. I'm happy with just collecting vintage hifi. I also need money but not that urgent.

In fairness to members of this forum, however, if you're serious enough to travel down south to Davao and would like to see my equipment, take your chance on any hifi unit you'd see in my place and if I'm in good mood, I might sell it to you at a good price. That's what Romy Martinez did a month ago, thus he went home with a Sansui AU-D907F at P5K (to be fair and transparent with members of this thread.)

The thing is I don't have the time to ship heavy gear as well as the patience to deal long distance. I admit I have too many in my collection and I'd probably want to limit my amps to only two dozens instead of close to three dozens now. But then again, I'd be equally happy to keep all of them. So, please understand my situation.

TU-D707 underneath and AU-D607 on top, what a sight! Those black Sansuis

That's a nice preamp, although the Carver brand was much maligned by US hifi enthusiasts even those in AudioKarma. Still, Bob Carver is an interesting personality with all those vintage hifi he was responsible for.  Check his classic fight with Stereophile here:

sayang nawala kay bob ang carver. actually, noon hanap din carver tfm amp but ended with adcom amp. kababasa ng mga magazines - stereo review, audio, audio critic, TAS etc. wala pa internet nung panahon natin na de-pihit ang pagdial ng talepono with matching crossline/partyline...

Kung rotary tuning yan, i-check mo sa technician na nakakaintindi meron lang yatang papalitan na isang piyesa (chip?) para maging US-standard at makuha mo lahat ng istasyon. Kasi, naalala ko two years ago, may nagpabili sa akin na Chinese trader dito sa Davao nuong part na yun sa Raon pero hindi ako nakabili, kasi out of stock.

Meron akong Sony Japanese standard tuner dito na converted at kuha lahat ang istasyon.

Dito sa Davao kasi, basta merong piyesa, kayang-kaya nilang i-convert yan. Yung ibang wise na technician dito nuon, ang sabi sa akin nag-stock na sila nung part na kailangan, kaya lang magbabayad ka ng medyo mahal pag nagpa-convert ka.

IMO mas magagaling ang technician dito pagdating sa Japanese surplus compared sa Metro Manila. Kasi siguro sa dami nang binagsak na mura kaya marami silang na-repair. Isa pa yung iba dito talagang may direct contact sa mga Hapon, nakaka-konsulta sila sa technical matters.

saan ka sa nueva ecija? taga san-isidro, malapit ako, pero nasa pasig ang familiy ko at the moment because my kids are in college...

just make sure that your units are clean inside and out, if you want you can momentarily plug it in at 110volts just so the capacitors have a chance to "reform" after a long lay-off....or you can series connect a 150 lamp for a minute....do not connect speakers nor plug in inputs just as yet...

the purpose of this excercise is to make sure no smoke comes out.... ;D

when everything is clear, then you can use your amp the normal way....type ko yung Sansui AU-D907X.... ;D

let me quote our in-house guru, sir sandawa,

For several years now, some posters in this thread have been asking me through PM for amp units I'm selling. For the Nth time, I'm not selling any. I'm happy with just collecting vintage hifi. I also need money but not that urgent.

 So, please understand my situation...

guilty of the same situation...
kidding aside, will let you know sir when I plan.
As of now, just happy looking at them even if not using them.
Just coming off from AU-777 usage, rotation use at least every 3 months to exercise the electronics/lytics..
Yes, its an engineering  marvel looking at the insides of those beasts, made by our audio forefathers.

just make sure that your units are clean inside and out, if you want you can momentarily plug it in at 110volts just so the capacitors have a chance to "reform" after a long lay-off....or you can series connect a 150 lamp for a minute....do not connect speakers nor plug in inputs just as yet...

the purpose of this excercise is to make sure no smoke comes out.... ;D

when everything is clear, then you can use your amp the normal way....type ko yung Sansui AU-D907X.... ;D

incidentally, medyo lamang ang PMA-830 kaysa 850 due the fact that it has "class A" output capability, yung 850 wala. but ultimately, we would like to have the 850 MkII, which is more powerfull and also has class A output..

Thanks. :) How is a receiver different from an integrated amp, on the amplifier part? :) Aside from the receiver having a tuner, does the amplifier of a receiver differ from the amplifier of an integrated amp? Bago lang kasi e.hehehe.

I am thinking of buying another integrated amplifier that has a better output than my current one and I am thinking of buying a receiver, after auditioning it, just because it is a sansui and has a greater rated output.hehe

Post by: iamlistening on Sep 23, 2009 at 10:56 AM
Thank you for the reply. :) Yes, I got the information from the translated site.I was just wondering what it means.hehe.

 Anyway, the amplifier looks like the picture above. No scratches and all the lettering are intact. In fact I think it was never been used, which is highly doubtful since the amp is older than I am. :)

It sounds very neutral, unlike the onkyo that I have. I do not get tired listening to it, and I could hear the more details compared to the onkyo integra A-722.

When I went to the pier, last weekend, they had a sansui power amplifier BA-150, one guy has already paid for it and it was reserved by him ( paid (6K) for it). I got the AU-1100 for only 2k. I was considering the AU-707 but the guy would not budge with his 6.5K price. So I kinda jump on the AU-1100 when i saw it was only selling for 2k.hehehe. Did I get the better bargain?

Hello Everyone. I have an OLD AVR http://audio-database.com/DENON-COLUMBIA/amp/avc-2000-e.html. I have tried connecting old speakers (from a mini component) and the sound is good. Any input on how to make use of it will be appreciated, like is it worth buying speakers to match this equipment, what speakers shall i get. Right now my setup is laptop (Dell Studio) with HDMI and Pana 37x10, i am just using the monitor out (Audio) of the TV going into the AVR. Is this better than buying HTIB?

Your ideas will be highly appreciated. TIA.

I just had my Harman Kardon 330C receiver restored with new caps and output transistor. Before restoration it sounded very good for a 20w/ch rms hi current amp. I'm excited to hear the "restored to new" version when I get my hands on it this week.  ::)

Does anyone here has experience on vintage h/k amps? I found the sound to my liking, even better than some Sansui, Pioneer, Marantz vintage amps I had before. It's more tube like to me, warm, smooth but detailed and airy much like the old Denons I had before also.  :)

A few months ago, I bought a complete audio analogue system; a paganini cd player and a pucini se amp.  Not being contented, I upgraded the amp to pucini setetanta to try out how 70watts will affect the sound imaging.  It was melodious to say the least.  Unfortunately a few weeks ago, I bought a marantz pm 550dc and I cant believe the sound coming out. It was fantastic to say the least.  the unit cost me less than 10k and it sounded better than my system! I can't believe it.  Now I'm hooked.  I started looking for vintage marantz in Manila but I guess there is a reason why they call it vintage. it is difficult to find.  I started ordering from the internet and hopefully, I get it before the end of the year :)  If there is any good soul here looking to sell their vintage marantz, think of me :)  I'm in the market to change my whole system.

soemthing to think about,  ;D they were saying the same when triodes were upstaged by pentodes in the mass market scene.....that was a good 50 ~ 60 years ago.

agree din. call it economics of mass marketing.

True, it's economics. Reproducing upscale vintage audio of the '70s and '80s today requires a lot of cash, notwithstanding increasing technology efficiency. A case in point is the decision of Luxman to reproduce its '70s and '80s amps.

SQ-38's last model in late '70s using 50CA10 tubes on power section was sold at 168,000 yen or roughly $700 at then prevailing exchange rate. The new SQ-38u released two years ago was sold at $5,000 if I'm not mistaken and it does not even use those much-acclaimed 50CA10s. When Jap audiophiles complained, Luxman's CEO said the retail price of the SQ-38u would double if they would use 50CA10s, which was produced by NEC for Luxman's valve line in the '70s.

The Luxman L-550, a 50wpc pure class A released in 1981 at 250,000 yen (just over $1,000 at 1981 exchange rate), was re-issued as L-550u two years ago with a new faceplate but at an introductory price of roughly $3,000. Sansui in 1999 also re-issued the 1965 AU-111 but with a huge price difference: 440,000 yen as against 65,000 yen for the original unit.

Surely, current manufacturers could reproduce the good sound of those upscale vintage units but at a much higher price, which only a very small segment of the market could afford. For instance, if the L-550u is sold here, its price would probably be at least P150,000. I can't afford that, besides I got my original L-550 at less than P10k.

Gud day! Anyone here has or experienced using a Pioneer SA-8900 Mk2, integrated amp, 100v japan version. I believe the american equivalent is the SA-9500 mk2.

dont want to offend you,suggestion lang.
since he is a friend, why not borrow and listen to it in your set-up?
ano po ba ang "audiophile grade soundquality" , in your own definition ???, iba iba kasi ang response ng tenga and likes natin.
however, these gears i believe conform to certain form of known audio standards to pass quality gates.
so, i believe its a matter of preference and being subjective.

You have a point there, though, layo kasi nya samin and I don't have a service right now. Also, I have my own insight on the pioneer though not as solid as, let say, marantz, sansui  or luxman, which I had the pleasure of using before. I also want to gauge my personal insight with what others would say on the amp para I can verify my findings din.  :)   
Title: Re: Surplus amps
Post by: dana on Nov 10, 2009 at 08:55 AM
Ok fair enough, understand your situation Allan.
I have some pioneers. The nearest I have with your inquiry about SA-8900II is my SA-8800II.
It is "audiophile sounding" to my taste.
I cant describe how good it is but is pretty much satisfied.
The bass is tight (just the way i like it) and the highs are just enough to sizzle. The mids are ok too.
Soundstage wise, it seems ok though I have limited listening space cramped with other things like furnitures around. The sound it produces is pleasant to me and is alright as listened by some friends.
I cant compare it with classic amps, though I have the feeling it can stand on its own merits.Listened to some though.
Besides, its very hard for me to recall the sound experience in detail for other amps. That is why, Im amazed when some described them in detail thru memory, describing/praising them so & so... :D
Im not a purist, if I feel the source material signal in  my set up needs some adjustments,I adjust the tone
as it pleases me and the way I feel the sounds ok.In the first place,I was not around in the recording booth, so dont know how those music was recorded, so I cant tell what is the actual recording sound (also, factor in the recording taste/ability of the recording engineer). I doubt also, even if I was there, if my memory can accurately reproduce the recording condition. I just adjust the sound if I feel it is too flat, or the percussion effects, the vocals need to be emphasized , too tame or what. Sometimes, I listen also to flat condition or in tone defeat mode, if I feel the sound material is fine.

mine looks similar lang, except for the green display:http://www.classicaudio.com/value/pio/SA8800.html
my pioneer set-up: generic dvd player as cdp > SA-8800II > decent spkr wires (gauge 12) > victor speakers:sx-3II/5II
gudluck :).

Post by: allan1836 on Nov 10, 2009 at 04:37 PM
Thanks very much dana, for your time in giving a short review of your pioneer SA-8800II. I'm sure it's a close relative to the SA-8900II, thus, similar characteristics. And with your statements, I think it's a good buy for me. Just wonder, is your amp powerful enough to drive floorstanding speakers with 89db sensitivity?

I admit I was a purist before and won't touch the tone control at all but lately my perception is changing.  :-\ This started when I tried combining PC audio with my home system. I found some music recordings (specially mp3 files) being enhanced by some music software enhancer like bbe on windows media player. Also, the limitations of the speakers, environment, etc. really need to be address by some music manipulation.

Again thanks for the help.  ;)   
Title: Re: Surplus amps
Post by: dana on Nov 10, 2009 at 05:24 PM
the amp (SA-8800II), has more than enough power of 80Wrms/ch @ 8 ohms load, .005THD, as specified) to drive an 89db sensitivity floorstanders, I believe. Question is, how loud can you play it as your environment permits? In  my case or usual case, 5 watts of power is  loud enough for home listening level (unless, its a dedicated/treated closed sound room). Some disciples/believers of SE tube amps, are happy with as small as 0.75W/ch driving a high efficiency vintage speaker system. :)

I also have the SA-8800II which I did a re-cap recently, its a versatile little integrated amp. I like everything of it specifically the tone controls which are similar to an eqaulizer, in fact I like it so much I placed it with in my luggage when I moved out of the country.  ;D

FWIW, audio amplifier manufacture in japan goes thru a certein "fad cycle" and so you will see amplifier topologies that are simmilar from brand to brand, it depends on what semiconductor chips are avaialble at the time of manufacture from such fab houses as toshiba, matshisita, fuji, sanken and others... ;D

parang lonta, minsan bell bottoms, minsan straight cut, minsan pitis....etc.etc......

minsan dual power transformers, minsan naman torroids.....

having a repair shop in the 90's afforded me a look inside many of these japanese amps, specially those coming from saudi and those brought in by japayuki's...... ;D

From my early impressions, compared to the Hafler DH-220 it is much more detailed and has wider soundstage. Don't know how to put in English but - mas manipis ng konti tumunog. And, the base of the Technics is much more distinct. I also think is sounds more analog when used on my CDPs - I have a Sony CDP-301V, 228ESD and X333ES.

Gutchy,

Oo. 4K lang bigay sa akin ni Manang. May nag offer din sa akin ng Sansui AU-X1 (taga South). Medyo nahirapan akong mag desisyon. Ang naging basehan ko na lang ay dahil may 907F ako at siguro naman hindi nalalayo ang tunog kaya pinatulan ko na iyung Technics. Anyway, kahit anong oras puwede naman ako bumisita sa Antipolo at makinig ng 907F. Medyo malayo pa ako sa SU-V10 pero kapag may lumabas noon susunggabin ko na  ;D

May malambing lang ng konti Sansui pero mas maganda ang base at soundstage ng Technics. Mas malalaman ko kapag bisita ko uli sa Antipolo. From stack knowledge lang kasi basehan ko sa Sansui.

Hindi ko pa na test sa Diatone, sa Sony speakers pa lang. Dalhin ko from Antipolo next week para ma burn-in iyung Diatone dito  ;D Buti ni-remind mo ako ...

It doesn't matter when CD was made if you're using analog connections.  

Vintage amps are just as good if not better than many amps today.   Technics is a well known high fidelity brand and this one was among their so-called "new class A" amps back then.  Provided the parts are original, get it. But that's the risk, you won't know it.

actually, mahirap talaga or di mo maririnig and difference especially if you are to compare them  on flat eq.(bass/treble defeat mode, loudness off) using same speaker and source material/player, because amps are supposedly designed neutral, designed with the objective of ruler flat 0 db freq. response.Flavorings na lan ung loudness,bass,treble settings. Also, iba iba rin ang freq response ng mga listener based sa study ni Dr Fletcher-Munsen  Curve...wag ka mag alala, maraming ganyan., di ka nag iisa.baka ung iba sabi lan may nadedetect na difference, pero wala tlaga deep inside ;D.ung iba, golden ear daw tawag...ewan ko lan...kung matiyaga ka, subukan mo magpa blindtest sa mga audio friends mo.
importante, maganda source material mo bago mo maenjoy music.
always clean your ears and as suggested ng iba, have the earwax removed clinically (once a yr?).

Anyone tried the Surplus shop sa kanto ng Edsa tapat ng isang condo near the GMA Kamuning MRT station? I saw some Hi-fi equipment there nung naghahanap ako ng pre-fabricated screens for my kitchen windows. Hindi ko na nga lang napuntahan yung section kasi nagmamadali ako.
Bisitahin ko nga ulit this Sat. :)

Up ko na din dun sa question ko for a reputable shop where I can have our vintage akai amps restored.

Hi Terii, long time no-hear from you. That's a heavyweight and very expensive I'm sure. Congratulations! how I wish something like that drifts to our islands. I had placed orders (for smaller items) at Hifido a couple of times since early last year but I was unlucky and always lose to European buyers.

POSTSCRIPT: I just checked Hifido. So, you're the buyer of B-2301 last week at 113,000 yen (over 1,000 euros). Including courier charge from Tokyo to Paris, I could be wrong, but your total cost for the B-2301 (37 kilograms) would be approaching (or over)2,000 euros for this unit?

Hello Sandawa, yes is long time
I have wavered between the Denon POA 3000 RG  and B 2301
Finally, I took the B 2301
http://www.hifido.jp/KWsansui/G0104/P0/A10/J/0-20/S0/C10-49717-52854-00/
B 2301 in France its rating is 1500 € over 2000 € depending on the general condition of the amp
Shipping to France is 45,000 yen by UPS and is the same price for the Denon
as I said long time ago on this forum, I prefer to buy directly in Japan
it costs less to me, it bothers me not that it is 100 volts
requires a very large voltage transformer
But the Denon POA 3000 RG is also interesting

What's good is that we're sure that Japan-brand 100v units were made of superior quality, unlike Japanese 120v or 220-240v units that are likely with inferior parts inside. By the way, there are vintage Japan domestic models of Accuphase and Luxman, originally in 100 volts, that have internal (transformer) adjustments for 220-240v.

Hi Terii,

The internals look more like the alpha907 series than the AU-X series -- four primary power caps plus two more on the side but smaller in size. Beautiful front face. I noticed B2301's price at Hifido is increasing. The other day, Hifido was offering another unit at over $1,500. Acquisition cost of that unit could escalate to $2,500 for European, or American buyers. Congratulations again!

Hi! I'm new here in the forum, but a long time lurker lol. I recently bought a Pioneer SA 8800 at a local surplus shop but I'm kinda confused when I saw these pics:

1. http://audio-database.com/PIONEER-EX...sa-8800-e.html

2. http://www.hifiengine.com/manuals/pioneer/sa-8800.shtml

My question is, are there two versions of this model? and which one is better? The first pic resembles the Pioneer SA 7500  ???
Title: Re: Surplus amps
Post by: sandawa on Aug 27, 2010 at 01:44 PM
dieseldust,

Yes, there are two versions of Pioneer A-8800, the Japanese and the US models. The US model looks better though with power meter window and blue fluoroscan. However, I'm one who believes that Japanese domestic units in general are more superior compared with Japan-brand units sold abroad including those in the US. That's because the international models were meant to compete in the mass market where quality is often sacrificed for looks. IMHO, however, the better Jap domestic unit comparable and probably even better than the US SA-8800 fluroscan model is the SA-8800II, which has two separate transformers likely with enough headroom to reproduce more accurately those low notes.

seanongpogi,

I'm hesitant to reply to your query since I'm not a 'master' and I haven't owned an M-73. But since no one was answering, the easy way for me to make a decision when confronted by this problem is to look at original and resale values available online.

The original price is here:

Tnx for the info sir sandawa. Finally, nahanap ko na rin ang surplus store dito sa'min lol! I bought the Pioneer A-8800 for 3,400. I consider it as a steal because as what you've said, it is superior to the Flouroscan models which were released in the US.
Title: Re: Surplus amps
Post by: sandawa on Aug 27, 2010 at 08:00 PM
dieseldust,

I think it's the Japanese Pioneer SA-8800II which is more superior than the US fluoroscan Pioneer SA-8800. Btw, William, the trader I introduced to you, has several interesting amps in his bodega here in Davao. If you plan to buy another amp call him, I think he's willing to ship.

I got a pair of classic US floorstander DCM TimeWindow from William a week ago. I'll post on the Vintage Gallery thread this interesting pair of speakers when I return to Davao next week.

Postscript: I had to edit my post, especially on my comment on SA-8800's pricing. I'm sorry.

Would like to inquire who among you guys have a NEC A-10 and what are your impressions.

P7.5k for NEC A-10 is reasonable, even cheap. I own an A-10 Type IV which I bought about 5 years ago. Used to be one of my favorites since it has good deep bass and could compete with the best at moderate room listening volume. The excellent low-frequency response is maybe due to its two big transformers (unit weight is 28kgs if I'm not mistaken although RMS rating is only 60wpc.) It has no tone controls, and I use it as power amp. Mine has three sets of speaker terminals, the first one labeled 'Direct' whatever that means.

In recent times, I realized it's not in the same class as Sansui a907, AU-XII or Luxman's L550. It's more in same category as Sansui a707, Accuphase 302, and Denon POA-1001 (all these amps are active at home where I work, thus I could compare, interchanging speakers and amps for years already).

Here are some photos of my unit:

Just a tip. The Sansuis, Pioneers, Marantz, etc. in the Marketplace section are priced very low considering the quality of those models and how 'bb3', the owner, took good care of those units. I know the seller personally. He's a collector not a trader and is not after profit but merely trimming his collection.

I too would like to sell over half of my amps and speaker pairs at roughly my acquisition cost and would be happy with just a dozen amps and probably a dozen-and-a-half speaker pairs at home. Unfortunately, it's not easy selling here in Davao. Shipping the units to Manila is a hassle and requires additional cost of over P1,000 per unit. That's because about 75% of my amps are over 20kgs in weight and air freight Davao-Manila is P60/kg.

Good to hear from you again, AV. I used to be a European- and American-brand fanatic too and I still have a lot of European and US brands on my shelves. This vintage Jap hifi disease, however, started when I got a study grant that sent me to Tokyo in mid '80s and saw those Jap audio equipment that never appeared on British and US hifi magazines.

In late '90s, I saw Jap vintage amps on several websites and realized those units could be shipped to us cheap as 'surplus' units. Those were the years when Japan introduced a minor revision in its electrical standard that pushed consumers to get rid of their old appliances.

Duon na nag-iba ang mundo ko ng hifi. Unlike before, when I could afford only one or two sets of good audio, now, with cheap 'surplus' equipment, I could collect the best units many of which not even The Absolute Sound, Stereophile, and British magazine editors have actually seen and tested.

The technology for high fidelity sound amplification has basically ceased after 1984 -1986 when the world's consumer electronic companies started their love affair with anything DIGITAL and multichannel.   What developed after was only a matter of addition, from 2.0 to 5.1, 7.1 to 10.1 channels.  But the basic circuit topography for each channel is hardly improved. In fact, they're regressed in quality because most discrete parts have now been reduced to ICs, the better to accommodate more channels.

About the only amplifcation technology that improved were those amps used to power subwoofers which are able to miniaturize the sonic ability to reproduce 26 hz into cube-sized 12-inchers.  They were able to improve on Class "D" topography which are never considered high fidelity due to high switching distortion products but are capable of high power of up to 1,000 watts RMS with efficient electrical consumption compared to class A and A/B.

Yup, it's trim-down time for me. Maintaining and rotating these 50+ amps can be a pain both on the back and pocket!
Am also anticipating a move to a smaller place late next year and unless my wife would consider sleeping beside several marantz or sui units, i guess i have to scale down the number. :D

Like you, will probably maintain about a dozen of those i would consider keepers. (the sui a707 would definitely be one of them ;))

Have been contemplating if the NEC A10x would stay.
which brings me to an earlier question about the NEC A10. If the sound of the A10x is any indication of how the older A10 performs, i would say that you hit it spot on Nani. Karangko nga ng a707 ang tunog. the A10x has the delicate highs and air of the a707, natural mids, and surprisingly packs a lot of lows for its 60 watt rating.
it does not have that colored, midbass bloom (some consider bloated) which i enjoy but more of a "higher end" sound - for lack of better words.

If i am presently on the market for an amp of this character, I would seriously consider these NEC series.

cheers

Boy, I'm sorry I get tactless sometimes in giving my opinion and comparing vintage/surplus hifi I have used or currently using. I believe the A-10X is superior compared with older A-10 models if HifiDo pricing is used as indicator. I almost texted you on the Sansui AU-D907 yesterday. Buti na lang nakapagpigil. Ayoko nang magdagdag, unless may mga Sansui limited edition na dumating, or '90s edition valve models would suddenly show up. Bahala na!

I'm focused these past days on a new combi: Luxman SQ-38FDII (1976) feeding Yamaha B3 (1980-VFET) and driving JBL 4313 (1979). I bought about 500 pieces of '50s to '70s almost-mint condition LPs from a warehouse here. Apparently, these came from an American vinyl collector -- about two hundred of Miles Davis, Bird, Coleman Hawkins, Chet Baker and other jazz legends -- covering 5 LPs daily, since early September. I'd say magical dynamic valve sound from these 30-year old gear reproducing 40- to 60-year old recordings.

BTW, for those who sent PMs, one or two I failed to reply to, I'm not sure yet, which ones I'd sell. PM me before mid-November, I'll be in Manila before Christmas.

Don't sweat it Nani. I understood what you meant.
I just wanted to point out also how these NEC series, largely unknown in the local audio arena, can really be 'sleepers'
just waiting for the audio community to discover their superior performance.
The dual mono A10X was constructed, I believe, in the same vein as the Cellos, Krells, etc.
Gold binding posts and thick copper chassis bed are just some features that put the A10X several notches above the rest. Even the location of the AC cable mukhang pinagisipan. It runs from the bottom/middle of the unit and not from the regular rear panel location.
Just talking about this really gives me second thoughts if I will let it go or stay.
As you mentioned - Bahala na! ;D

my problem is i can't seem to find a replacement for it., the original part is nma1216 and nmc1216, even its 2sc and 2sa replacement is hard to find..  hope someone can help or direct me where can i find those tranny.. Thanks in advance

nma1216 and nmc1216 are toshiba transistors made specially for sansui. May mga original T0-3 type sanken transistors pa na binebenta sa raon, pero paisa-isa na lang at mahirap makabuo ng apat na pares (assuming apat na complementary pairs ang kailangan mo). mas maganda na lang try mo yung motorola na replacements na T0-3 type din (merun ata sa alexsan, sa raon din). At least makakabuo ka pa ng complementary pairs.

If Japanese buyers' preference is used as basis (see HifiDo's past transactions), assuming both units are in same condition, the Sansui would be a better buy. The highest last transaction of a607 at HifiDo was quoted 35,000 yen while the Integra 917F was sold 30,000 yen.

I think SPEC 2 and SPEC 4 (which are popular in the US) are actually international versions of Japanese Pioneer's M-77 and M-75. Problema hindi nilabas ng mga Hapon yung mga (Pioneer) Exclusive amps nila. Baka ayaw ipa-kopya sa mga Kano, parang SIT/VFET amps ng Sony at Yamaha.

Kung ako sa 'yo, bibigyan ko ng full amount yung nagbebenta ng Onkyo 917F. Pero may option to return, say 2 days, with 'rent' of P250 (or P150) per day. Ibig sabihin, kung hindi ka satisfied, isosoli mo ang unit balik ang pera mo less P500 for the 2 days you used it.

Kung magustuhan mo ang unit compared with a607, wala nang solian ng unit at ng pera. I-dispose mo na lang yung Sansui a607 mo. At least hindi ka magsisisi dahil pinili mo yung gusto mo. 

I did that a couple of times here in Davao, I usually risk P500 for a two-day trial of amps costing over P5k. At least I'm sure I got what I want.

Darn, I was able to drop by at Chattys 4 weeks ago, got my eye on a Sony ES-555 DTS Receiver, got a glimpse of this Pioneer Integrated Amp that says on the front "Simple and Straight". I think its a pioneer UK3-MK2 with a detachable power cord and no tone controls. 3.5k according to Ate Vangie, did'nt paid much attention because of the ES555 only to find out later that night when I did a search that it was the same as the legendary Pioneer A-400 and classified as being one of the top ten must have audio equipment of all times, its no 4 on the list, no. 1 is the Linn Sondek turntable.

Called the next day, reserve na daw.

one way to know is to listen to it, better with your own set of speakers and your source material.
if its good to your liking, go for it...

to some, the more you read manuals or info related to this hobby, the more confused you become & the more you doubt your judgement ;D

Wala na rin dumadating dito sa Davao. The last good model -- Luxman L550 -- that I got early this year came from a Cebu dealer of Jap audio surplus.

What happened, if I'm not mistaken, was Jap consumers have already adjusted to the government's new electrical standard that was imposed about 3 or 4 years ago. Since yung lumang equipment non-compliant sa new standard, binenta nila or binigay sa recyclers bago na-implement officially yung bagong policy. We benefited from that since the early discards were sent to our ports and sold by local traders at "junk" prices (remember the controversial JPEPA -- zero customs duties for imported recyclable materials from Japan?).

Also, Jap vintage hifi are sold at a premium in Shanghai and other major cities in China, up to 10 times higher than the price we buy those items (high-end hifi sa kanila yan at mas mahal kaysa locally made 'upscale audio' products). Kaya yung mga recyclers sa Japan, sa Chinese traders na nagbenta starting 2007 as per stories from Davao importers/traders.

If you badly need a good Jap hifi gear, the best way is to get it from HifiDo like what American and European audiophiles are doing. But be prepared to pay more. The original Luxman L-550, for instance, would sell at about $1,000 in Hifido before freight charges. I got two units of this from the local suppliers at an average acquisition cost of less than P10k each.

There are bargains though -- an example is Technics SL1200 series, a new edition mint unit could be bought as low as $200. Dito kahit sugatan na ang SL1200 tumatakbo pa ng P20k. Also, cartridges and some audio accessories (mostly useless, but good for bragging) are also cheaper via HifiDo.

Less problem kung receiver ang gusto mo. Kasi ang Japan receivers naman hindi mo magagamit ang tuner, hanggang 90 Mhz lang ang FM. You have to scout from local ads for receivers issued in US -- kuha lahat ng istasyon. Got one -- MCS 3233 (JC Penney brand) -- last month from a warehouse here that buys used stuff from Goodwill in the US.

Kasing laki at kamukha ng Pioneer/Technics heavyweights pero apa ang loob. About 10 kgs lang pero 19X7 inches. Sa 30 wpc, disente na ang tunog after pairing it with JBL 316 Pro in my living room. Sabi nila gawa raw ito ng Technics or Kenwood, likely inferior parts, and rebadged as 'Modular Component Systems' for JC Penney. At least pwedeng pang-harabas, P2k lang naman.

Title: Re: Surplus amps
Post by: sandawa on Nov 23, 2010 at 06:07 AM
Pwede mag-rechannel/re-tune ng Japanese receivers/tuners pero hindi ganun kaganda ang labas. Maingay, or hindi pa rin makuha lahat. Malaki ang diprensya sa original 88-108 Mhz na US/Philippine tuner standard. Kaya hindi nagpasok ang mga importers ng maraming Jap receivers dito sa Davao dahil binabalik ng buyers yung mga unang benta. Unlike the amplifiers where buyers don't have much expectations. Basta nakalagay sa likod at least "100 watts" at binabayo yung "200-watt" speakers nila (kailangan daw pala at least doble ang rating ng speakers, sabi nung mga tambay dito  ;D ;D ;D ), okay na.

Yes, the MCS was bought here in Davao. I saw a smaller Superscope receiver (with the label 'Superscope by Marantz' at the back) quoted at P1.5k when I bought the MCS but I was in a hurry and it has no sound when I first tested it. It was gone a few hours later when I returned to the warehouse.

pwede yan, na try ko na, medyo mas tataas ang rails mo dahil 200 lang ang magiging rating nyang nakaseries....

ang rails mo ay tataas ng factor na 220/200 or 10% higher.......

ang isang hindi maganda dyan ay kapag mas mataas ang power draw ng isang channel, medyo magbabatakan sila......

yup, that is what i mean.....if you want, you can series connect the primaries and parallel connect the secondaries so that in effect the two transformers becomes one unit, that way even ang draw sa two traffos at maiwasan yung pagbabatakan nila.....

to connect the secondaries in parallel, you have to take the corresponding wire from one traffo and connect to the same colored wire of the other traffo, do this for the center tap also...you now have to series connect the primaries, and inrder to find out if you have the correct polarity, connect at 220 incandescent lamp in bettwen the two transformer primaries and then the other 2 wires to your 220 volt source, if the lamp light up bright, then you have the wrong polarity, just reverse one of the leads and you are done....

remember, to get the polarity right, the lamp must not be lit when you connect it to the power source...

side effect ng pagtaas ng line voltage ang pagtaas din ng magnetising current ng traffos mo....

pa rewind mo na sa 220 para wala kang sakit ng ulo...

Mga expert, Good Day po! First time ko lang po member dito... Medyo nahihilig na din po ako sa mga vintage sound set up, baka po matulungan nyo ako kung san pa pwede makabili ng Preamp module (Onkyo P-309 o Lo D HCA-9000) na maganda po yung bass out put nya at may subsonic na din po pati na merun din kayo mare rekomenda parametric equalizer... Marami salamat po. Vhinx

Salamat po sa feedback Sir Sandawa, If possible po na merun kayo benta na PreAmps yung swuabe po sa sound output lalo na sa bass eh paki inform na lang po ako... Wala na po kasi ako makita maganda sa pier manila eh kaya.

BTW, starting pa lang po ako mag collect ng mga vintage sounds module simula lang po mabasa ko mga forum na PinoyDVD at PinoyAudio, lalo na po ng makita ko mga collection nyo dito... Ibang-iba po talaga yung ganda sound pag branded lalo na vintage set up.

For now po, I have Sansui RG-900R Equalizer, Victor XL-V313 CDP at Pioneer PD-7070, Kevler KX-650 speaker (using Knozert & Sakura amps lang) at soon baka po makuha ko sa Tito ko yung Luxman-507u amp at Coral DX-5B speaker nya bago siya balik sa abroad.

Marami Salamat po. Vhinx

Hi All! It's been awhile since I posted here, medyo na iba ang bisyo.  ::) But lately I have been tinkering again with my audio toys, hirap talikuran talaga!  ;D I recently acquired a rare Sansui AU- Alpha 507 MRV in good condition. I bought it on impulse since it's an alpha series though this model was a more recent (1997) product from Sansui. I've owned earlier alpha series versions and found them very nice thus I expect similarly on this one.  And I was not disappointed !  :o

The sound of this relatively newer alpha series is for me more transparent and has deeper bass than the earlier alpha series, though generally the midrange is a bit thinner. But this was augmented with a sweet and open sound.

Now I've seen models like the alpha i, mrx, nra,mosfet series, etc. in the net but this mrv is very hard to researched on. Can I ask the experts here a short history, review on this alpha 507 mrv? Is this model be considered a collectors item? TIA  :)

Here are some pics of the unit I found on the net (exactly the same as my actual unit) :

About 5 years ago when we had so many used Japanese amps arriving here in Davao, the Sansui a707i would be quoted at P5k and the D-707x at P4.5k. The last time I saw an a707i, two years ago I think, the price was P6k and a D-707x at P5k. I think your traders there in Bacolod are using HifiDo as price reference -- those amps are still selling in Japan's used market at roughly $500 each.

I bought a near mint condition vintage sansui AU-555A in pier, about 4 or 5 yrs ago. haggled it for 2.3K without the step down voltage transformer.  it has separate bass, midrange (YES! midrange) and treble controls.  I see indications it was manufactured in Japan in 1971. I haven't replaced any capacitors or any parts inside, its build is very good.

Lately I paired it with a used acoustic research M4 holographic imaging speaker I got from a garage sale, ...and the music is.... very sweet, very musical....  I love the midrange....and the bass.... no need for subwoofer for well recorded CDs...

It has been compared to having a sound very close to that of a tube amp. see below:

Here's a bit of the good description from http://www.sansui.us/Amplifiers.htm

"Once upon a time, Sansui was a mere transformer manufacturer.  It was natural progress that Sansui started manufacturing amplifiers and tuners in its early history.  In the late 1950Â’s to the early 1960Â’s, Sansui had developed a sense of mission to be a world class audiophile manufacture.  That was the reason that Sansui introduced the first pre-main (integrated) tube amplifier SM-88 in Japan.  Sansui introduced only two more tube integrated amplifiers, AU-70 and AU-111, before they moved forward to the solid state silicon transistor amplifier, AU-777 in 1967.

From 1967 to 1970, Sansui introduced the array of the single number three digits integrated amplifiers.  They were AU-222, AU-333, AU-555, AU-666, AU-777, AU-888, and AU-999 followed by improved versions; AU-555A and AU-777D.  The sound of this series was very close to that of tube amps.  Even mixing with tube amplifiers with frequency divided multi-power amps system, it sounded natural".

Check all control and switches for any noise. Ask them to open up the cover (if they will allow this) and see for any sign of repair or burn marks. Burn mark is a sign an over heating component. Also check for bulging and leaking capacitors.

Listen for any distortion while playing music. Play with the switches and control, see if everything is working fine. Let the amp play music for awhile as some of the problem while only show up when the amp starts to heat up. And if you can, bring a test disc wherein you could listen accurately to the left and right channel to hear if they sound both equal.

I hope this helps.

Mabigat at hindi gaanong maporma. Kapag sinilip mo yaring tanso iyung kaha at mga heatsink tapos dambuhala mga capacitor at transformer tapos presyong halos konti lang lagpas sa abot kaya, huwag ka ng mag-alinlangan bilhin mo na. O hindi kaya i-reserve mo na at utangin mo na ang kulang. Kunin mo na agad baka may makauna pa sa iyo.

Surplus yan! for 28K, it is not worth it. Lumang modelo na yan at mga parts nyan ay pwede na bumigay anytime. Specially mga electrolytic capacitors nyan ay nagiging leaky na. Pwede yan sa 28K kung 10 years free parts n labor warranty (joke lang).

Hanap ka na lang bro sa mga japan surplus store. Dun din kasi bumibili mga taga pier kaya lang wholesale sila.Nagkalat mga japan surplus stores kahit saan. happy and lucky hunting na lang.Pag may magandang dumating ay tinatawag na yan sa mga favorite suki kaya tsamba ka na lang kung abutin mo pa.

Sa Eastern shipping dati kami nagbababa surplus electronics from japan at may shop ako dati sa tapat ng bahay ng mga Araneta sa Farmers Cubao. Nagwhowholesale kami sa Raon at the rest ay binebenta ko sa shop sa Cubao.

Sa ngayon kasi, Mas mahal bumili mga Vietnamese, Hongkong at ibang kapit bansa pa kaysa sa atin kaya dun napupunta mga magaganda electronics.

Sansui AU907 series, pwede na yan sa 5k. Marami kasi bagito na pumapatol sa mataas na presyo kaya nagmamahal paninda sa pier. pero konti na lang dumadating electronics sa ngayon kasi halo na ng mga furnitures ang household items laman ng mga container na galing japan.

High demand kaya high price...

madami pa ba surplus amp sa pier? thanks!
Title: Re: Surplus amps
Post by: allan1836 on May 10, 2012 at 10:30 PM
Halos wala ng surplus shops sa pier for audio electronics. Mas mabenta ngayon surplus bikes and furnitures as I see it. @juanbote is right, most surplus audio items are redirected to Vietnam or China, which is funny, since as we know China is the oem makers of almost all know electronic brands. But, it seems Chinese audiophiles, still prefers Japan made products. This says a lot of the quality of domestic Japan products and also reflects the quality of the new breed of audio products.  ::)

I also want to know if meron pa bang good source of surplus audio electronics sa metromanila or talagang nearing extinct na.  :D

The late 90's to early 2K is the golden era for me sa pier. Luckily, that time, I was working at Del Bros at South Harbor so after work diretso sa audio shops don. I remember seeing all those hi end amps, cdp and speakers naka balandra lang sa harap ng mga stores. Your wallet is the limit lang sa pagbili noon.  ;D Haayy... those were the good old days.  :)

newbie here pero matagal na akong lurker sa site na to. Saw this Yamaha a-1 and victor a-x55 this morning. Pinili ko yung yamaha over victor kasi parang mas maganda yung tunog nya. yung speaker pala na ginamit namin ay diatone ds-73dii.  i bought the amplifier and speaker for 6.5k.  maganda din ba yung victor a-x55?

parang popcorn nga. malakas nung mga unang beses. nagsimula to nung medyo tinaasan ko ang volume. akala ko nasira na ang bass ng diatone kasi malayo ang inabante ng cone at parang tumigas tpos dahan-dahang bumalik sa normal position.

you have to let your technician check it out, clean the boards, look for cold solder joints, these are usual in mass produced boards......

ipa-check mo na sa technician bale yung ac out nya sa power amp di na pantay yung voltage kaya parang may pop-corn na yung tunog yung trimmer malamang nagchange value na at pati yung mga electrolytic capacitor luma na din....nakakasira ng SPEAKER yang ganyan problema dapat pang testing mo yung mga patapon na speaker na lang...TIA!   ;)

Title: Re: Surplus amps
Post by: sandawa on Jul 30, 2012 at 07:45 AM
Sorry, pero sa totoo lang, I can't comment on the model you mentioned since I haven't used one. I probably owned over a hundred amps already in my over 35 years in this hobby -- from European to American and lately mostly vintage Japanese. Pero isa sa pinaka-konti sa major Jap brands na nasubukan ko yung Sony, probably the most is three amps. In fact of over two dozen amps I have now here in Davao, only one is Sony (555 ESG) but I'm quite happy with it.

Swerte ka meron kang a907. Bihira yan dito sa Pilipinas. It was never released in the US market and very few units were sold in Europe, halos walang inilabas sa UK, instead sa France at Germany sila nag-benta.
Title: Re: Surplus amps
Post by: banesto on Jul 30, 2012 at 04:11 PM
oo nga po sir sandawa, marami nga kumukursunada ng a907 ko pero nang mabasa ko ang tungkol sa a907 nyo ay lalo ko itong minahal. tama po ba sir na lagi kong pinipihit ang mga control ng 907 3 times a week para maiwasan ang cracking. ok po ba yun. minsan kasi dinadala ko pa sa technician e super bigat at mahal maningil.
Title: Re: Surplus amps
Post by: sandawa on Jul 30, 2012 at 06:09 PM
Ang akin a907iMos Ltd at a907. Yung a907 may problema, hirap ang technician ayusin, iba daw ang configuration kasi ng a907 series at mahirap ang piyesa. Parang multi-stage amplification yata ang sabi sa akin. Kaya siguro iba ang buga niya sa woofer. Kung hindi ako nagkakamali, 28 kgs ang a907, yung a907iMos Limited, 31kgs. Meron din akong AU-907 Limited, parang de-tubo ang tunog pero kulang sa power muscle, tulad ng AU-X series.

From experience, effective ang a907 series mag-drive ng big woofers -- 15-inch types. Kaya nuon JBL-4430 (now bi-amped with a pair of Sansui AU-X11s) ang nakakabit sa a907iMos ko. Ngayon yung Technics SB-7000 na. Maganda rin ang resulta. Kayang-kaya niyang palabasin yung deep bass ng big woofers di tulad ng iba kong amplifiers, even those rated 160wpc and above in RMS, parang bitin mag-drive ng big woofers.

Anak ng putakte..hehehe…ung technics ko na 8080a nagtampo ata , naghahanapn daw kasi ako ng technician lol

Kanina while playing around 40-60mins at 10oclock vol biglang nawala ung sounds sa speaker – hindi naman mainit ung amp
nakaON pa din naman ung amp and cd player was still playing

pinatay ko den lumabas ulit ung sounds then parang pumupunta sya sa protect mode…after a minute

so ginawa ko pahinga after 30mins played Olivia ONG songs nakatapos ng 5songs then nagpalit ako ng cd – craig david – nawala ulit ung kanta
usually I use the amp more than 5hours  pero now ko lang naexp to hehe..

so turn off and on nagprotect mode ulit
so what I did was to  there was a setting sa amp    DC and LOW CUT 2hz
always naka DC si MAIN – theres a light indicator for DC
binaba ko sya sa LOW Cut then everything was fine I played for 30mins kaya lang papunta na ako office…bukas ko ulit kalikutin…bakit kaya..??

any opinion guys? salamat

I'm not sure bro, pero yun DC was supposed to be for Direct Control sa main amps which means for pre-amp bypass, merun din ako amp dati na Vintage Onkyo Integra na merun din DC servo na nasa clipping control section naman. Yun LOWCUT naman ang pag kakaalam ko sa pre-amp LOW & High's filtering in the other terms is "Subsonic Filter"... Wait lang tayo sa mga Master of Vintage gear for further explanation sa concern mo bro. ;)

Yup mag kaiba sila, yun Lowcat for pre-amp filtering na pag switch mo sya ay mag change freq yun Low and/or even high's... Yun DC if I not mistaken use for source direct to the main amp (at hindi na dadaan pa sa pre-amp which is tone control - BASS & TREBLE)...

Sir kunin niyo na iyung Marantz. Kapag iba iyan baka wala na iyan. Mahirap mag-testing ng maayos sa mga surplus shops kaya hindi magandang basehan listening test doon. Kahit pa siguro nasa 8k hanggang 10k kukunin ko iyan.

Mas maganda tunog ng Class A. Mas malambing, malinis at mas detailed.

Kailangan mo lang ng high sensitivity speakers specially sa Marantz PM90 kasi 25W per channel lang siya. Kung mga 90dB pataas speakers mo mas maririnig mo ng maayos kung ano ang diperensya ng Class A sa Class AB.

Mas maganda tunog ng Class A. Mas malambing, malinis at mas detailed.

Kailangan mo lang ng high sensitivity speakers specially sa Marantz PM90 kasi 25W per channel lang siya. Kung mga 90dB pataas speakers mo mas maririnig mo ng maayos kung ano ang diperensya ng Class A sa Class AB.

+1 Sir Mel, and its better to use exchaust fan for excessive heat if you use class A mode... :) ;)

may isang concern pa mga brader. PM90 is 25wpc in class A, recommended amp for Mx5 is 25-200watts, ano ang magiging resulta? TIA
Title: Re: Surplus amps
Post by: rascal101 on Aug 04, 2012 at 09:56 PM
Kapag mababa sensitivity ng speaker hindi magiging ganun ka dynamic ang tunog tapos medyo kulang din sa low freq. Kapag nagka budget ka mag high sensitivity 92dB pataas full range ka na rin  ;D

Puwede ka rin mag-abang sa Pier ng 25-40W rated power na speakers. Mga 70s o early 80s speaker mga ito na kadalasan Alnico iyung gamit na magnet. Maganda iyung Diatone at Sony speakers (base sa mga nabili ko). Mga 1.5K to 2.5K usually mga ganitong speakers sa Pier.

mga braders, need your comments pls.
napadaan ako kanina sa isang japan surplus shop, may nakita akong sansui AU alpha555 and a marantz PM90. I tested the PM90, kya lang di maganda yata condition ng speakers, pero good sounding pa rin,  they are selling for 7500. does anybody knows kung magkano na dapat ang price nito, considering this is a 1991 release., sinubukan kung buhatin, nabigla ako, super bigat pala. 27kg

hi sir! nasaan po ung surplus shop na ito? thank you! :)

ok bro, maraming salamat sa mga payo :)

if you are a purist, then it might be good to start searching for the matching sansui pre-amp. if not theres a multitude of pre-amps out there to try from Solid state to tubes...

Klipsch reference  RB-3 is a very good speaker, because of high efficiency you don't need a much higher wattage amps. Match this with tube pre-amps (hybrid) or use tube buffer on your CD output makes a good start.\While using tube amps is the excellent match for this speakers

I'm no master bro, pero istorya ko lang sa iyo ang ginawa ko, noong nakita at natesting ko si marantz PM90, iniwan ko muna sya, internet agad ako, ni review ko ang capability,specs, reviews, etc, and best of all, ikinunsulta ko dito sa surplus amp thread, at dahil sa payo ng mga members, nabili ko sya and enjoying very much the surplus amp ;) ,for me, I prefer good condition branded surplus amps than ::).... happy hunting :)

From experience, effective ang a907 series mag-drive ng big woofers -- 15-inch types. Kaya nuon JBL-4430 (now bi-amped with a pair of Sansui AU-X11s) ang nakakabit sa a907iMos ko. Ngayon yung Technics SB-7000 na. Maganda rin ang resulta. Kayang-kaya niyang palabasin yung deep bass ng big woofers di tulad ng iba kong amplifiers, even those rated 160wpc and above in RMS, parang bitin mag-drive ng big woofers.
  Hi sir Sandawa, gud day po. Para sa inyo ano mas gusto nyo tube amp or ss amp? Gusto ko sana kasing sumubok ng tube amps esp. tube pre amp. Thanks
Title: Re: Surplus amps
Post by: sandawa on Aug 21, 2012 at 10:56 AM
Depende yan, nasa room ko yung Luxman SQ-38FDII, which is a premium tube amp, but I did sell low (lugi!) my Sansui AU-70 and Wired State Tono.

That means, I'm more of the solid state type since I like alpha 907 series a lot, better than the Sansui AU-X series or even the Luxman 550, a classic pure A amp. The AU-X, by the way, is regarded as tube-sounding by audiophiles in the US. It's described by Sansui enthusiasts as a purists' amp, pero manipis ang tunog para sa akin for a 160wpc 30-kg amp.

Also, among my favorite combinations are SS-based: Yamaha B3 Vfet with Epos 14; and Sansui AU-D907 Limited with DCM TimeWindow.

Siguro yung hardware preference, depende sa music na pinakikinggan. I like folk and folk-rock, vintage pop as well as big sound chamber music, or choral pieces for my gears in my living room, malakas ang volume. Acoustic/vintage and electronic jazz as well as classic strings and piano are usually played in my room.

I'm close to 40 years into this hobby by the way.

Thanks Sir Sandawa, sabi nila magastos daw ang tube amp. Batay sa paliwanag nyo stay muna ako sa ss amp. tutal nakapakinig na ako ng mga tube amp to my friends at sa pakiwari ko di pa rin sila satisfied. Parehas tayo Sir ng type ng music like slow rock and vintage pop music. Nasanay na ang tenga ko sa a907 kaya pag napakinggan ko yung ibang amp ay medyo nakukulangan ako.

I only have a Yamaha NS-120 speakers and I'm not sure if kakayanin nang speaks ang amp since it's rated at 200wpc while my speaker ay nasa 200w peak na. ...wat dya think mga sirs?...TIA

Mura nga, swerte ka. That used to sell P5k up even during the peak years of vintage hifi here in Davao (5 to 12 years ago). P3.5k could only buy AU-D607 during those years. Yan ba yung kay Kano, sa GSIS Village?

Naku po! Hindi totoo yan, napakaraming collectible Sansui amps na wala ako. Siguro medyo nakapili lang ako kasi roughly 30 years na ako dito sa hobby na 'to. Kailangan lang talaga marunong makipaglaro sa traders, but not necessarily buying at high price. During the early years of vintage Japanese hifi here in Davao, I even deposit cash to get first priority on arriving surplus amps. Kung minsan, natutulog ang pera ko for months pero halos ganun din naman sa bangko ngayon. At least, you earn goodwill and future favors from an honest trader for just a 4-figure deposit. Sa bangko, with that amount, you're nothing.

Walang issue yan, pwede yan kahit sabay.

Since may Volume control yung isang pre-out,Try mo din tangalin yung pre-amp and DIRECT yung variable na pre-out sa Power Amp.

if your handy with the soldering iron, check the power supply boards for leaky caps or caps that not in the right shape.. if not bring it to a qualified technician

thanks sir banesto, check ko caps nya pagbalik ko, may iba pa bang dapat i check by ocular inspection regarding its condition? syempre, di ko sya ite test para kunyari tanggap ko sya na defective para mababa lang ang tawad ko, he he
Title: Re: Surplus amps
Post by: qguy on Oct 11, 2012 at 09:15 AM
Check the large caps if intact  and no cracks sa bottom, these tend to be on the expensive side.  Check mo na rin sa net if may mga parts na unobtainium or unavailable or expensive to be on the safe side. Some models of output transistors were specially made and are no longer in production, I know sa Pioneer meron unobtanium parts, sa Sansui I am not sure

if nag pro-protect malamang may problem sa power supply, but that does not mean na yung lang ang problem.

IMHO, not unless super cheap or super rare yung item, I would not buy if it does not sound, ok lang yung mga, thumps and pops when you  flick switches or adjust th evolume control as these can be easily fixed.

Marami pinanggagalingan/sanhi nang nag "protect/clipping", It is possible from main power supply (X-former, E-Cap's, regulator, etc.) - Then Power amp (transistor/IC/Cap's)... Pwede ma-repair yan pero hindi tayo sure kung merun pa avail na parts specially IC's & Transistor's.

Pwede mahingi yung contact number nung technician, sir? Walang reliable Sansui/Luxman technician malapit sa amin. Thanks!

Sir banesto, kayo yata makaka tulong dito...


Salamat sa reply.  Blue housing na alps yung volume nya.

Merun po Alps vol pots sa eleshop manila pero yun standard na gray lang @ 50kohms nakita ko.

Btw, kung yun Sony at onkyo mo ay vol pot lang problema, pwede mo muna pansamantala pa replace nang ordinary pots for the meantime habang nag source out ka original parts para pwede mo muna sila magamit.

OK na ang sony at onkyo ko mga masters.  Replacement volume muna pinakabit ko sa sony amp baka kasi may makita ako sa future.  Yung onkyo nman nilinis lng ng technician ang volume.

Sansui 707f - pinalitan ang sanken 2sa1215n tska sanken 2sc2921n. nxt week ko pa kukunin.

Sansui 907 limited - problema daw nya ang relay.  Nakuha ko kanina at

eto xa ngayn.

Medyo malayo yung shop nya ngayon compared sa dating pwesto if your coming from the South but I think it's worth the trip. He specializes with Sansui by the way.

Hndi kasi pwedeng subukan ang mga amps sa warehouse.  Ang pwede lng ay i-plug at tingnan kung may power.  As-is daw kasi yung bentahan.

2sc5200 at 2sa1943 available sa newport at electromark less than 100 each....

sir tony, kung gagamitin ko itong 2sc5200 and 2sa1943, meron pa ba ko papalitan na component pang bias sa transistor? o derecho papalitan ko lang sa socket?
(-edit TO-3PL pala casing nito sir  :-\)

Nakausap ko din si Sir Dan, titingnan daw nya kung meron pa sya nma and nmc transistors.,
sa tingin nyo should i opt with the original kung meron pa available or replace ko na lahat?

the mjl21194/21193 have the same casing as the 2sc5200 and 2sa1943, and these japanese trannies are better in terms of gain linearity (beta droops) and frequency response than even the original trannies in your sansui.....

the mjl21194/21193 have the same casing as the 2sc5200 and 2sa1943, and these japanese trannies are better in terms of gain linearity (beta droops) and frequency response than even the original trannies in your sansui.....

yes sir,MJL21194/21193 is to-3pl package (same as 2sc5200/2sa1943) and MJ21194/21193 is to-3..

Mga sir.   Meron po bang mabibilhan ng STK3102IV para sa Marantz PM-80 ko?  Meron xang sound output pero after 3-5 seconds nawawala.  Tingin ko yun ang sira kasi kalimitan daw sa model na 'to yung STK ang problema.

Decided to get back into the hobby after a couple of years of time off :) Rather than having my Luxman amp in storage repaired, I thought of looking up some items in the market section. Unfortunately, I missed out on this deal http://www.pinoydvd.com/index.php/topic,173455.0.html  :(

To cheer myself up, called in sick to work last Monday ;D and headed to the Pier (boy, did I miss that place). After countless "ano hanap mo, boss?" and going through all the familiar stores, with no hopes of finding a gem really, I stopped by this store that sells mainly sewing machines with a few amps on display. Still nothing. Pero napansin ko sa katabing store may mga amps na mukhang for repair lahat. Tingin-tingin lang and underneath the pile of amps and literary nasa pinakababa....BULAGA! Sansui AU-D907

parasmi: Boss, for repair ba lahat ng items nyo dito?
technician: Yung iba gawa na, sir.
parasmi: Saan dyan yung mga sira?
technician: Yung naka hilera dun (pointing to where the Sansui is placed)
parasmi:  Eh magkano po yung Sansui na nandun sa pinakababa as-is?
technician: Ah yung 907? (aba! alam nya) OK na yun, sir
parasmi: ;D
parasmi: Magkano, boss?
technician: 8,500
parasmi: ;D

Wala ng tawad-tawad, inspect, testing, bayad, balot, uwi

It's basically the A-717/A-71 with video switching capabilities. Per specs, it can drive a 4-ohm speaker

Mga bossing, brader and guru's first amp ko ay isang Luxman m-120a, near mint condition, bought at a shop in Dau, Mabalacat.

Newbie pa po ako kaya wala masyadong alam sa quality ng mga amps wether it's new, used or vintage.

Ano po masasabi niyo sa power amp na nabili ko. Any feedbacks will be highly appreciated.

Thanks... :-D

A few months ago, I bought a complete audio analogue system; a paganini cd player and a pucini se amp.  Not being contented, I upgraded the amp to pucini setetanta to try out how 70watts will affect the sound imaging.  It was melodious to say the least.  Unfortunately a few weeks ago, I bought a marantz pm 550dc and I cant believe the sound coming out. It was fantastic to say the least.  the unit cost me less than 10k and it sounded better than my system! I can't believe it.  Now I'm hooked.  I started looking for vintage marantz in Manila but I guess there is a reason why they call it vintage. it is difficult to find.  I started ordering from the internet and hopefully, I get it before the end of the year :)  If there is any good soul here looking to sell their vintage marantz, think of me :)  I'm in the market to change my whole system.
mer0n akong vintage marantz receiver sr4000 bka my interested dyan

Yes sir, Just went there again yesterday. Found some PA (mackie's, mcintosh, peavy etc...), receivers (sherwood etc...) and processors (iba iba brand), mixers (mic and generic) and a lot of brands that I don't recognized. Usually mga pang mobile po mga amp nia dun (e.g. Ramsa) at sa isang store may nakita ako na audio video distribution amp (nakalimutan ko lang ang brand) with lots of input and outputs at the back.

Was lookin for speaker to be paired on my Luxman amp, may nakita ako dun na Cerwin Vega VS-100, JBL 2800, Jamo floorstanders, Grundig, an old Sansui speakers (defective tweeters and edges), JBL j2050 BS. Meron din pala mga guitar amps like Hartke

Got another vintage amp from a new source, it's a Trio KA-7300.

Update lang po mga brader, lumipat na ang LTO sa Metrotown Mall. Wala na din mga surplus shops dun sa dating puwesto ng LTO.

Kagagaling lang kaninang tanghali at nag-ikot ikot para maghanap sana ng mga amps. Sa isang electronic repair shop nagtanong ako kung may alam siya na nagbebenta, wala daw siya alam at yung mga kanya ay nabenta na niya. Inikot ko mata ko sa shop niya at di ko inaasahan na makikita ko ang isang Sansui TU-7700 Receiver. Yun nga lang may nag-mamayari na daw sabi ni manong technician.

Anyways pati na wood restoration (on going - hubo ang amp ko ngayun) and inspection from a technician roughly around 10K na, such a little amount for the sound that I was lookin for (I guess somebody might quote me on this but of course we know that it's a highly subjective matter) since I got started in this hobby.   ;D

Have done some cleaning on the knobs & toggle switches (using WD-40 and a hair dryer to get rid of any residue) and faceplate (liquid soap and water then wipe it with 3M microfiber cloth para iwas sa scratch) para di lang maganda ang tunog pati na ang looks, hehehe

Makikihalo lang ng konti. Kung 100 volts yang L-505V (Jap domestic model), meron yang adjustment for 220 volts sa loob, tabi ng transformer. The unit should be unplugged when you make the conversion.

In my case, I slid the switch from 100V to 220V when I got my unit over 10 years ago -- tapos ayaw tumunog! I then uncovered the 100v/220v switch plate, removed the wires connected to the 100v terminals and connected them to the 220v terminals.

After completing this process, I realized even the two outlets at the back of the unit are already 220v. Unfortunately, I realized I have already 7 vintage Luxman amps last year so I sold my 220-volt L-505V at a price slightly higher than my acquisition cost.

Here's the undressed unit (yung merong white arrow ang switch)

you let the cat out of the bag, this is a very helpful trick....:D
and inexpensive too....
what i do is clip all leads and sort out the connections for 220 and
make direct connections, the extra joint leads covered with shrink tubing
and ty-wrapped into a neat bundle, so then what comes out is just two
wires for 220 volts...
not all amps can be tweaked like this, it depends on the way the traffo was done,

here is a link of the Theta Tube monoblocks i converted to 220 without a sweat,

as an aside, Japan domestic models are of better quality than export models.... 8)

Title: Re: Surplus amps
Post by: sandawa on Oct 02, 2013 at 02:43 PM
Not all Jap domestic amps have hidden switches inside though, even the Luxmans. I have five more Luxmans here: SQ-38FD, 2 units of L-550, 1 unit of L-530, and 1 L-80 Silver Anniversary Edition. All five have fixed 100v power.

But I found out the same trick applies to my Accuphase E-302. Nakalagay sa likod 100 volts, kapag binuksan mo, meron din syang 220v switch na nakatago sa loob.

Does that mean doesn't have provision for wiring to 220V?  :(

I was deciding if pa-rewind na lang but otherwise will retain na lang ang original voltage input as I'm using an AVR (500W) at the moment.

Papakuha daw niya sa tao niya duon para malaman ano mga models.

parang SM dito, they've got it all.


si raff (darkangel), mukhang maraming hinahakot lately ;D, naambunan tuloy ako ng TRIO na pinagsawaan na nya :)
Anyway, para medyo related sa mga nagbabakal (vintage amps...), Darkangel posted way back that he used WD40 to clean the pots and slide switches. I dont recommend that, since it leaves a grease type residue. Instead, you can use the cigarette fluid (FUJI, in red plastic), mura lan or  Ethyl Alcohol...
use syringe, para sa mga hard to reach - patak patak tapos konting pihit pihit.

You said that for me before.....Well kanya kanyang tenga yan....Some were Luxman lover....Some were Sui's
lover etc....etc. For me Sansui esp vintage hi end amplipiers sounded best. Other amps lack in mids or hi's or bass.....other amps was good in mid's and hi's but lack in bass or vice versa..... As for Yamaha.... I have also
Yamaha amps before maybe 3 but I'm not satisfied so I sold them. I have so many Vintage Sansui amps esp
hi end....Two of my hi end amps like Sansui AU-919 and Sansui AU-Xlll Mos Vintage goes to Forseti. They are all
super mint condition, Yung iba di ko na maalala kung sino nakabili.
          Many pdvd members kept Vintage Sansui like Sir Sandawa, Forseti and many others. You can ask some
advice with them. Sansui Alpha 907 made me feel satisfied so wala na akong ganang maghanap pa ng ibang
mga amps. Parang nakuha nya lahat..... Yung bass....mid....Hi.....perfect lahat para sa akin. At pulidong
tumunog.

lang to be safe kumuha ka ng mint na higher model lalo na kung hi end.

Have been researching on those western amps (Leach, Oviation, E-amp, Quad 405-2) that uses onsemi transistors and would build one before this year ends. Will probably start with the Oviation sx which is a 15w RMS symmetrical CFA topology Pure Class A, it uses MJL1381 and MJL1302 on its output stage.

Before I even got my vintage amps I bought a defective Marantz pm54 to be used as a case for a Class A amp that uses MJ21195/96 output transistors but never finished building one as I got busy looking for integrated amps in pier and later on near our area (Pampanga).

super mint condition, Yung iba di ko na maalala kung sino nakabili.
          Many pdvd members kept Vintage Sansui like Sir Sandawa, Forseti and many others. You can ask some
advice with them. Sansui Alpha 907 made me feel satisfied so wala na akong ganang maghanap pa ng ibang
mga amps. Parang nakuha nya lahat..... Yung bass....mid....Hi.....perfect lahat para sa akin. At pulidong
tumunog.
           Just try Sansui amps sir para malaman mo ang pagkaka iba.....Ikaw mismo makakapansin nyan, kaya
lang to be safe kumuha ka ng mint na higher model lalo na kung hi end.


sir Ernie, I have been told that my Sansui BA-150 came from you...
How would you compare its sound signature with other Sansui amp in your stable?

thanks Sir! I'll ask my friend about it.

I think it's the PC park Japan shop, same as the one in MCS. I find their pricing on the high side though.

BA-150 sounds detailed with gud hi's and mid's. It's only 45wpc but it sounded well enough esp at lower
volume.

Just came from H&R in Pasig.  They now carry branded surplus amps/speakers.  I saw a few polk studio monitor 50s and 70s floorstanders,  onkyo htib,  martin logan floorstanders and subs,  a lot of sony subs, etc.

Make sure to test the units before buying.  Every time I go there, I see someone complaining about a defective product although a tv I bought there 3 years ago still works perfectly.

Merong mga tuner, amps, guitar amps at lots of speaker doon.
Meron din mga guitar and toys.

Matanong ko lang. Marami pa rin bang AMPS na mabibili sa Pier? I would really like to find a good music stuff with small budget. I read the start of this thread. Merong recommendations na I agree that are good AMPS. But its way back 2003.

Any models you can recommend na I can still find?

Ang hirap pa kausap ng mga nagtitinda dun, power consumption daw ang sukatan nila ng presyo pero bakit mas mataas bentahan nila ng power amplifier nila samantalang halos kalahati ang agwat ng integrated amplifier sa power amplifier. Isa lang sagot skin, ganun daw kasi talaga.

Marami kasi don wala talagang alam, binebase lang nila sa mga ginagawa ng kapwa nagtitinda, kya madalas lumabas na overrated ang paninda nila hence overpriced. Parang kala na wlang alam lahat ng mga tumitingin don. Mas mabuti pa mag antay kana lang dito kaysa MAGaksaya ng oras don ;D

Para sa mga surplus/vintage amps, anong mga parts ang dapat palitan so that the amp will be usable for many more years, and usually magkano ang nagagastos for these replacements. I guess this additional cost should be factored in para sa mga nagplaplanong bumili ng mga surplus or vintage amps ;). Hope somebody can comment on this .Thanks in advance

Question lang mga brader, do we need to shell out huge amount of money para lang ma-attain ang audio nirvana or even just the satisfaction of hearing a good sounding amp and speakers?

I know di tayo pare pareho ng lalim ng bulsa, yung iba dito sobrang lalim, yung iba sakto lang, ako naman kakaunti lang lagayan ng bulsa ko, hehe. Anyways most of the audio enthusiast here swear to the sound of Sansui (bias ba?), I'm sure as with most everything that's tangible you can't have it all pero I like the idea na sana maging open tayo sa klase ng amp kung mosfet man o transistor ang output na gamit at huwag puro na lang Sansui ang nababasa ko dito sa thread na ito. After all, this is a thread for Surplus amp and not Sansui thread. Madami na ang nagpost na sabi trust your ears pero puro Sansui lang ineendorse, what's with them anyway? Padinig nga minsan para naman mai-compare ko sa mga amp ko na nadinig na at ginagamit ngayun, hehehe

Currently I have acquired a Diatone DA-A7000, it's a 6 channel amp and compared to the 607 and 707 of sansui I would choose the sound of the Diatone hands down.

Meron din ako Sui 707 at 919, pero mas nagagamit ko si never heard.

Medyo nakukuha mo din pala nasa isip ko bro, :-D
Same with the Sony TA-1055a, a 20watter amp pero you would be surprise at how it sound, huge soundstage for a little amp.

Take note, pag tiningnan mo ang loob ng amp na to... matatawa ka, kasi parang yung mga amps na mumurahin at liliit ng components. Kaya talagang nagulat ako. Traffo, tranny at caps puro mukang kolokoy lang... ;D

Malaking bagay talaga amp-speaker matching. I've experienced this (Di ba Ka Ernie? ;)) Madami akong amps na TOTL, pero isa lang ang talagang gusto ko :)

At buti na lng may dalawa akong speaker na kahit alin sa amp ko ang ipares ay maganda pa rin ang sq though magkaiba syempre ang sound character nila.

Hindi naman malalim bulsa ko kaya pinag-ipunan ko talaga alpha 907, i was hesitant nga kasi i haven't heard an alpha before kaso nung dumating and nakita ko kung gano kasariwa parang i forgot how much i spent for this amp, lalo na nang nadinig ko, and yes match sya speakers na i have. Ako din bugbog na tenga ko sa praise ng alpha dito sa thread so i opted to source out one dahil walang mahanap dito. Luckily napakaganda ng nakuha ko
Title: Re: Surplus amps
Post by: Hammerheart on Jul 07, 2014 at 06:02 PM
I have spent so much sa iba ibang amps kung susumahin mo sobra sobra pa pambili ng alpha 907, and yet yung 907 ang money well spent ko. I had many good amps but not as great as this one. All i can say is that alphas are meant to be paired with B&Ws :)

Question lang mga brader, do we need to shell out huge amount of money para lang ma-attain ang audio nirvana or even just the satisfaction of hearing a good sounding amp and speakers?

I know di tayo pare pareho ng lalim ng bulsa, yung iba dito sobrang lalim, yung iba sakto lang, ako naman kakaunti lang lagayan ng bulsa ko, hehe. Anyways most of the audio enthusiast here swear to the sound of Sansui (bias ba?), I'm sure as with most everything that's tangible you can't have it all pero I like the idea na sana maging open tayo sa klase ng amp kung mosfet man o transistor ang output na gamit at huwag puro na lang Sansui ang nababasa ko dito sa thread na ito. After all, this is a thread for Surplus amp and not Sansui thread. Madami na ang nagpost na sabi trust your ears pero puro Sansui lang ineendorse, what's with them anyway? Padinig nga minsan para naman mai-compare ko sa mga amp ko na nadinig na at ginagamit ngayun, hehehe

Currently I have acquired a Diatone DA-A7000, it's a 6 channel amp and compared to the 607 and 707 of sansui I would choose the sound of the Diatone hands down.

Very subjective ito. Depende rin kung saan na nasanay ang tenga ng listener. Our ears will eventually adjust or adapt to what we usually listen to. I dont think I can claim that "this amp is better than this one". Its just a matter of taste, 'ika nga nila.:)
Minsan din, when we suddenly hear something different from what we have, akala mo mas maganda na. In time, makikita mo rin mga flaws (para ding sa bebot ba? :D)

Sir darkangel69 are talking about the alpha 607 and 707?
On the contrary i happen to listen to an alpha 607 extra and was extremely impressed. Maybe the alpha 707 is better as one of my friend from cebu is bragging about it. Oh well our musical preferences really differ.
Ako kasi if i would be offered an alpha amp be it a 607, 707 and hopefully 907, i'll pay for it without any hesistation. Napaganda ng alpha series ng sansui. Sa 607 pa lang i am very impressed na lalo na siguro 907. Padinig joey. :)

I can bring my victor ax1000 or the diatone da-a7000 so I myself can make a direct comparison over sansui's alpha series. We could use a set of speakers or two.

Simple analogy lang audio. The reason why marami nagsasabi na sobra ganda tunog ng Sansui because they have tried and heard other vintage brands like Pio....r, Lu...an, Ke....d and ended up liking Sansui. I agree not all models of sansui are good sounding, pero when you get the chance to hear specific models, I'm sure game ender.

I myself was a trying hard hobbyist to high end audio before. I used to own Krell KSA 50, and I still have some brands from my amp collections, pero when I heard the vintage sansui amps BAM!!!! yun yung sound na gusto ko. Simple principle lang audio " Cause and Effect", siyempre pag maganda tunog automatic sasabihin ng listener na maganda, mahirap magsinungaling sa sarili ha ha.

But again, nobody is pushing the brand sansui here, it's just so happen sobra ganda lang talaga tunog.

Another testament for liking sansui, you can check other international forums eg.

In fact they are drooling to get and collect sansui in their stash.

Sir how do you compare the sound signature of the two brands( Accuphase and Sansui ), specifically the vintage models. I have not heard any Sansui vintage sing. Hanggang himas lang sa display sa Sta Rosa. 
Title: Re: Surplus amps
Post by: banesto on Aug 03, 2014 at 05:40 PM
Ngayon lang din ako nagkaroon ng accuphase e-205 but nagulat ako sa sounding ng accuphase.....
Very much detailed....the LF is deep and alive and the mid and highs are very sweet. Well sobrang linis
talaga tumunog ng accuphase, kaya pala napakamahal nya. Para sa akin both alpha 907 and Accuphase
E-205 ay parehong maganda.  :) sa linis tumunog medyo lamang ang Accuphase.  :)

Marami na ring nagsusulputan na maganda sa ibat ibang ibang tindahan kaya palagay ko ay hindi na parehas dati kung saan sa may Pier lang. Sa dami rin ng mga amplifier, speaker, etc etc na binebenta ngayong sa "marketplace" ay hindi mo na kailangan pang lumakbay ng ganun kalayo.

Ang siste lang siguro ngayon ay hindi na tulad dati na madali makahanap ng murang vintage high end. Meron pa ring mga high end pero triple o apat ng beses na presyo kumpara sa dati.
Title: Re: Surplus amps
Post by: Tempter on Aug 09, 2016 at 12:08 PM
Wala ka ng makikitang maganda don both presyo and unit. Puros pinagpilian na, at yung mga natitirang magandang model pinagkahuyan na overpriced pa. Kahit sa speaker puro overpriced din, as if naman sobrang gaganda hehe!!!
Title: Re: Surplus amps
Post by: rascal101 on Aug 22, 2016 at 05:12 PM
Tiempo tiempo din. Depende rin iyun sa dating ng kargamento nila. Di naman kasi sing dalas ang dating ngayon kumpara dati. Tsaka mas marami na ring mga bidder ngayon. Eh kung nakuha iyung container noong ibang bidder na hindi taga Pier eh di ang bagsak ay sa ibang lugar.

Kailangan mas masigasig ka at di lang sa Pier umabang para siguradong may makuha.

Hello all, just bought a wharfedale 220 and paired it with a sansui 207ii. I'm somehow torn between the matching as I feel that there is something else better. Would you be able to recommend an amplifier suited for the bookshelf. I'm currently looking at the surplus amps up for sale at our local resellers:

> Pioneer SA 8800ii
> Yamaha AX-890
> NEC A-700
> Trio KA 3002
> Sony TAF 555ES
> Kenwood DA 1100EX

If you have other recommendations please feel free to let me know so I can look it up.

I have the same setup in the past SA 8800ii + wharf 8.1.... This Pioneer paired well with many speakers, amps and pre-amps I had. Now in moderate use I've re-capped it since then...definitely a keeper.

My hk citation 21.Not really a surplus amp.finally had it fixed after not running for 20+ years. I'm amazed with what it has done to my simple setup. Time to look for a turntable as i now have a phono input.

Question. If my power and pre amp have volume controls. Which one should i set to max and which one should i use to adjust the volume.

Dami dati sa Pier. Dun nga ako naka score ng iba't ibang "mamahaling" amps, speakers at CDP.

Kakalungkot at naiba na ang panahon. Dati rati nasa 3-5K lang mga amps. Ang speakers mas mura ng konti tapos ang CDP naman mas mura sa mga speakers.

Same yan with surplus car parts from Japan. Medyo mahirap na ang stocks coming in from Japan because our neighboring countries like Malaysia, Indonesia etc are gobbling up the inventory.

You are far better off sourcing it from the US.  Doon nagkalat mga good condition 70's. 80's and 90's amps.  Sa Flea market lang dami mo makikita.
