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.

this amp has superb construction!

8 filter caps on psu ====> low esr!

heat pipes, fiins on copper pipes, freon fluid coolant inside the copper tube carries heat way from the output trannie junctions effectively!

mc phono capable using step-up input transformers!

what more can i say? this is a "must have" collectors' item!

and at 2,800 this is a steal......

Mga Sirs,

Ako po iyung nakabili ng Sansui AU-D907F sa tulong ni Sir Gutchy. Akala ko pangit iyun pala ... Yun di ang sinabi ko sa Yamaha CA-1000 noong dumaan kami ni Sir Gutchy sa Pier noong nakaraang Martes ... Pagtingin ko sa niji the ff: day ganda pala nung CA-1000. Noong binalikan ko that day wala na raw. Noong umaga kinuha iyung Sony TA-4650 at Yamaha CA-1000. Mahirap talaga magsalita ng "pangit". Nakakadalawa na ako (buti na lang noong una nakuha ko iyung Sansui). Sa susunod uling shipment sa Pier hinding hindi na ako magpapalagpas at ... wala nang salitang "pangit"...

BTW, mayroon din palang surplus shop sa Bulacan ... Dumaan ako noong Saturday at nakakita ako ng ... Sansui AU-D907 ... Php 2800 lang ... Unahan uli ...

Guthcy.. ...I got the Ca1000 and TA4650....after i came back for the 907 that u already got. I used the money earmarked for the aud907 into getting the two amps. So you can see how good your amp is. Dalawa ang katumbas!!!

sandawa · « **Reply #1413 on:** Oct 24, 2005 at 01:00 PM »

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.

Mga Sirs,

Iyung pong Surplus shop sa Bulacan, "as is" at "no return no exchange" ang bentahan. Hindi po puwedeng buksan. Iyung Sansui AU-D907 wala po iyung speaker connections niya. Other than that mukhang wala nang ibang missing. Tinignan ko iyung pictures sa http://www.sansui.us/images/AUD907/ at parehas na parehas iyung hitsura. 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.

Foo.

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 lord foo,

Thanks!

Oo nga sir dalawa katumbas.. kc sa power rating cla tumitingin.. pero sir good buy
din ung dalawa nyong amp.. sarap talagang mag-collect ng ganitong amp.. everytime na mkakita ako ng magandang amp sa pier dko mapigilan ung sarili kong bilhin.. hay!!

sir rascal101,

ok pa ba physical condition nung mga amp sa Bulacan?
bka may makita kang Yamaha AX-2000 dun.. PM mo skin..

Thanks!

sandawa · « **Reply #1419 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.

Mga Sirs,

Di ko pa alam kung kailan dating nung container. Pa sched pa po ako. Anyway, para nagkakaintindihan tayo lahat pwede huwag niyo muna patulan iyung Sansui AU-D907. Minamataan ko kasi iyon. Kung oks na lahat ...

Pwede sabay sabay na lang tayo getting there at pagdating dun pagkasunduan na lang natin kung kanino mapupunta iyung mga pinagpilian na amplifier. Magdesignate tayo ng number sa isa't isa at ibobola natin. Kung ano ang napili mong number mapupunta sa iyo ang nakadesignate na amplifier.

Dadaan ako ngayong Saturday Oct 29 around 10am.

Anong say niyo ...

2 x 230watts is a very good figure! how much are they selling this amp?

rascal101 · « **Reply #1430 on:** Oct 30, 2005 at 05:05 AM »

Mga Sirs,

Sabihin ko na location ... di ko na binili iyung Sansui AU-D907 (BTW nasa Sylvia's ito ...)

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).

There you have it folks ...

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.

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".

sandawa · « **Reply #1437 on:** Oct 31, 2005 at 09:02 PM »

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.

akyatbundok · « **Reply #1438 on:** Oct 31, 2005 at 09:46 PM »

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!
