That is a great help, thanks James. I had a service shop diagnose the amp and they said three of the transistors were bad and the estimated it would be $250 to replace them all. So, I'm considering doing it myself!
If you mean the output transistors the one that I worked on had 2SA1265 (PNP) and 2SC3182 (NPN), 2 pairs per channel for a total of 8 outputs. I used ON-Semi NJW0302G and NJW0281G.

The driver transistors were 2SA1306A and 2SC3298A. I used ON-Semi MJE15033G and MJE15032G.

For the other assorted transistors I'd have to look, it's been a while.
Cheers,
