Hello,
I bought a defective Accuphase P600.
Unfortunately one side of the power amplifier is broken. All 2SA1170 and 2SC2774 are defective. Does anyone have a tip where I can get these as not fake? Or can I install a replacement, which shouldn't actually be done with a device like this.
Does anyone perhaps have a circuit diagram of the device?
Kind regards, Mario

You can use both 2SA1295 / 2SC3264 or 2SA1216 / 2SC2922. Same house, pretty much the same otherwise.

Ah, maybe I should amend that suggestion. Stick to 2SA195 and sibling. The output stage is quoted as to develop 82,5V, so better safe than sorry.

How many are blown?? And yes...... these are genuine NOS. Only have these 4 pairs though 😉
There's this guy (Megaheinz) on Old fidelity.de who has a paper document, it might be worth trying to contact him.

At the moment I have installed 3 of the 2SA1494 and 2SC3858.
I have on output 500mV. Is is possible to adjust, or I have another problem?
I checked all the Transistor on the board and the Diodes too.
Attached the file from the other forum. I don't have better quality.
