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!

something intresting......  but after collecting 2 amps, and forever waiting for that ever so hard to find models i have grown weary and shifted to surplus speakers and cdps....

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

I would replace its amp module into a LM GC!  ;D  to make it productive in my setup!

Absolutely right! Especially if you have the time. Kaya nga inggit ako sa inyong mga GC masters diyan, lalo na yung JojoD ang handle, hanep daw kumana 'yun!

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!

maganda ang tunog sir, dahil siguro sa dami ng filters. pati yung mga masama sa original recording ang dinig ko parang naging mas listenable. sabi ko nga, mas maganda ang epek compared with Tono. pero kanya-kanyang dinig yan, baka naman defective na ang tenga ko.

relay70,

have you auditioned those amps you mentioned? mahirap din kasi maghanap ng specs sa net kaya all you have to do is audition them and decide kung ano swak sa panlasa mo bro.

Good luck on your hunting!  ;)

yup sir audiobyte its a Yamaha AX-1200 "junk" or surplus unit...... non-surplus items are alot more expensive, but this one seems to be missing the front panel that's why its considered "junk"...... sayang didn't have enough time to coordinate with our contact there, bidding closes in 2 hours and the highest bid is still 1.5k.

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.

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.
