Genuine Sanken 2SA1216 Supplier

[Delboy2]

As per title, I am looking for a replacement 2SA1216 Sanken transistor for my Audiolab 8000P as a fault with my DAC caused the said transistor to depart along with a common emitter 0.22ohm resistor. With there being many copies around I would be grateful if someone knows of a genuine supplier.

Cheers

I always had good luck with B&D, but the last Sanken MT-200's that I bought from them blew up in my face after a very thorough rebuild on a Nikko amp (worked fine till I ran it with full primary voltage, and then disintegrated...usually a sign of bogus parts).

 

[XEAGLEKEEPER]

I've had pretty good luck.I guess.I've used them (Sanken MT-200's) in Yamaha M-80's & M-85's under full rail at WOT on dummy loads--No problems and no complaints..

So far I have had no problem Sankens from B&D. They are my first stop looking for Sanken parts.

Delboy, I´ve got around 50 pieces left of both 2sa1216 and 2sc2922, even with the same prod. number on both npn and pnp. PM me, and we can find out something. I guarantee, these are genuine

Hi,

I just bought 10 of each 2SA1216Y and 2SC2922Y from them for a dead 8000P with some dead outputs. It was kept in a wall unit with doors and probably got too hot inside for it. It might have been forgotten and left on with the doors closed. Years of use too in too warm conditions because of wall unit and no air conditioning probably took their toll too!

Does the Y mean they should match well enough? I was thinking of replacing all outputs or is that a waste? Would any of the other transistors etc. be damaged too?

Thanks in advance!

I was under the impression that each channel only has one pair, can you post a photo of what you are looking at?

 

[Delboy2]

Each channel has 2 2SC2922 & 2 2SA1216's this is in the audiolab 8000p - in total 4 2SC2922's & 4 2SA1216's. The fault on mine caused 1 2SA1216 to demise along with 1 0.22 uf common emitter resistor (white with 3 legs). I replaced these and now works as before on mine there are glass diodes which look nothing special until there is a fault - they illuminate red, there is one of these diodes per pair of transistors.
Was wondering whether changing the op-amp (TL071 afaik) with a burr brown would improve the sound quality??

 

[richie00boy]

OK. I would change all devices to be from the same batch on the channel you repaired. The other channel you can leave alone. So you should just have one device to swap out - the "brother" of the one you already did.

The op-amp is for the DC servo and won't affect sound.

Thanks Richie!

I think you answered my question. So no further matching is required if they are from the same production group a long as it ends in the same letter?

thats far to simplified an approach IMO, they will likely be close, but they will not be matched

 

[rmyauck]

Matching outputs

QUSP,

How close do they have to match? I'll have to figure out how to test them.

Thanks very much in advance!
