It could just be the angle the pictures were taken, or maybe it's the way the shrink was applied to the caps. But the two caps I've marked with red arrows look like they may be bulging.
If so, I'd be re-capping before I used it again, using caps rated for 105 ºC. Some of those Pass amps run hot!
Mr. Shovel,
I think your right. Never dawned on me as I have been using it.
Want the job? I can send it to you. I really don't want to deal with transistors. If one blew I wouldn't know what to do to trouble shoot it.
Paul,
That makes two of us! I "lurk to learn" here on the Tube DIY Asylum. As little as I know about tubes (compared to the regulars here), I know even less about SS.
Maybe you could find someone at the link below who would be of more help.
Good luck.
Plate = collector
grid = base
cathode = emmiter

I noticed a brown spot in the middle picture.
The upper tranistor looks to be getting hot.
I would change both of the transistors in that channel too.

That burn spot looks to me like a bad solder connection overheating. The middle lead on a TO220 package is the usually the collector so there would be some current there.
Since this amp is so simple and old, I would replace all the transistors with modern types based on the Pass and ESP pages.
But again, this was not a very good amp IMO, especially in it's legacy configuration. You can do much better and even the Pass site has gone beyond this old design.
