Need amp repair help - Can you ID this semiconductor?

[GaryM]

IT LIVES!!

Here is my final schematic with mods for the Road Electronics amp. Got it fired up today and it sounds fine.

As you can see, it has all new transistors. I balanced the differential pair, biased the class A stage to dissipate 2W total, balanced the VI limiter and sundry other changes. The bias circuit was the biggest change. The plastic bias transistors are bonded to the heatsink and it tracks temperature better than diodes.

I haven't verified the VI limiter transistors for proper bias as of yet.
