pagkakaiba lang ng acquisition natin sir eh ung sa akin is working,but the seller told me the minor defect,actualy cnabi nya na as-is daw bilihan
ibig sabihin ala ng balikan,pag good condition daw kc 5.5k benta nya(na sa tingin ko eh mura na kaya na icompare ko sa presyo ng SA A5)
cnugalan ko na,kc gusto ko talaga unit.swerte2 lang talaga pagbili.
ewan ko lang ba bakit...........basta happy ako sa amp ko.

you are one of my idol pag dating sa vintage,pati si sir mb88 and southpeak.

Ah ok,with those VU meters....Very relaxing to the eyes,dances with the music

[allan1836]

rodel5, mukhang para saiyo talaga unit na yan ah!  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!!    It also confirmed my theory that wharf speakers really need good high current amp to perform their best.

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...

[sandawa]

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):

Ok,my apology kung nasagasaan kita.pero wala akong intension na ganun

           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

pero sir,pede ko pa din siyang lagyan ng receiver hindi po ba? kahit generic lang..?

heads up lang

[allan1836]

rnb_zounds, yup bro exact piece un pics mo!  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" .  
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). 

[jaklord]

how much kaya sa pier: integra a-817ex?

[rodel5]

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.

[sandawa]

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).

[jaklord]

got already an onkyo integra 817ex from little chatty, 6.5k ung asking, haggled it up to 5.5k.

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.)

Sir sandawa,

Thanks for reiterating those excellent tips. Your contribution toward increasing our appreciation of vintage Japanese gears is well appreciated.

[dana]

Yes, agree to that...
Thanks Sandawa-san, not only from me but also from the rest of the bakal boyz out there

[Jairus]

Very informative post, as usual, Sandawa.  Thanks!

Problem here is, di na naman mapapakali mga bakal boys sa pag aligid sa mall hoping na may matisod.

Just want to share my James B. Lansing SA600 amp, though not surplus nakita ko lang sa house ng friend ko. Actually sa Uncle nya to just collecting dust dun sa place nila. 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.

  I started googling sa internet regarding this amp. and i think naka jackpot ako  .  Anyway here's the link regarding the amp:

Just dont know how to post pics of the actual unit. Need help on this.

i always get a kick  whenever  i go to this particular site. how lucky can one get

Hifido, the company where I bought the sansui AU alpha 607 mos limited, I have since 2 months and this is my preferred by my sansui
And await the arrival of alpha 607 cd player

[sandawa]

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.

sir sandawa,

saan po ba sa pier maka-ka-purchase ng quality power amps?  I am keen on buying a 3 power amps with dual mono construction.  Am not familiar with old amp models, please suggest a reliable brand and its model. thanks

[dana]

For your transformer needs, try contacting Edrel Sison 0917 5107948.
He & his company make quality transformers.
He can customize according to your load and needs.
I suggest palagyan mo na ng primary switch & fuse protection ung transformer mo.

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.

No, I am not a philipin but Tahitian living in paris
You are the priviliègés to philipines, you can do business in the surplus, we do not have on PARIS. Such sales on the 907 i mos limited, I almost buy it at hifido but as I had booked the next 607 NRA2
  Who will return to store at hifido patient then I
