Default X-ref for 2SC2526 and 2SA1076

I've looked everywhere and can find no information or cross-reference on the 2SC2526 and 2SA1076 transistors. I have a Pioneer receiver (SX-3900) that uses two pair in parallel per channel (non-switching class AB?), and would like to order up some extras just to have on hand.

Does anyone know what these would cross with, or who would still make them. The originals were made by Sanken, but there was nothing on their site about them.

Thanks,

Mike

Post specs

Hi Mike,
2SC2526 specs are:160V 12A 120W hFE=110 fT=80Mhz
2SA1076 specs are: same except fT=50Mhz
The above from The (Japanese) Transistor Manual, 1986.

If you can mount the plastic MJL3281A and MJL1302A, you'll be flying.
If not, try to find 2SA1216/2SC2922 or 2SA1494/2SC3858.
As a last resort, try whatever these cross to in ECG or NTE. I test these before using them.

Default 2SA1216 and 2SC2922 will be more than enought

They are Sanken Devices too.... 250Watts, 150 Volts, 16 Amperes, Ft enough.

Good Luck.

Carlos

Carlos... I think they are 200w not 250w devices... also they are 180vce not 150v and 17 amps not 16A LOL Carlos, you need some sleep!

Default replacement overkill

Either way, mjarve has the answers enough to help I hope.

Default Cross with 2SA1295/2SC3264

>Anatech
Is crossing 2SA1076/2SC2526 with 2SA1295/2SC3264 a good idea?
Luxman L530 needs to be repaired.
Regs,
Jarek

Hi Jarek,
Yes, but your new ones are a little slower than the originals. Power, voltage and current are all greater.

I don't think the sub will be any trouble at all unless they are fakes.

The originals were made by Fujitsu, not Sanken.

The closest are Toshiba ring-emitter power devices, even have a case that looks a bit like the strange ones of the 1076/2526.
Not made anymore either, but can be found ocassionally. (now and then i stumble on a few of them, usually buy them for a few dolares)

Best Sanken match are the 2SA1215/2SC2921, several shops sell these for lower prices than the 2SA1295/2SC3264 pair.
(unless you are able to trace a few 2SA1094/2SC2564)

Nice amplifier btw, the L-530 was just about the best integrated in the mid 80s. Better than a Revox or an Accuphase, unless you had twice as much cash for an Accuphase E303.

Hi Jacco,
Agreed, a very nice amplifier. I had the pleasure of working on them under warranty.
