UPDATE. ok, there were 4 TIP35c's so the 35c's went on one side, and the 36c's go on the other, can someone tell me which side goes where?

I would check the output mosfets first and replace where necasary.
If the chips still get hot then one or more might have fried.

Had a similar problem on 2092 based system and the mosfets frying took out the 2092 too. Replaced both and teh amp was fine.
