I just shorted that diode and it did cool it off.   

I've got about a little less than 100mV at the speaker terminals. 

I come from the world of analog synthesizer repair and often times replace all the capacitors in a synth as part of preventative maintenance.  If this isn't how it's done with amps, dually noted.    

There were a whole series of issues that needed to be repaired in this amp.  One of the filter caps was toast.  There was a transistor that was bent / shorted in the pre-amp section.   All easy fixes.  Everything sounds great now, I just worry about the temperature of the output section. 

I believe this amp is a clone of the Peavey Standard 260H.  I do have schematics I can scan at a later point if this would be helpful.  I appreciate everybody's input! 

I replaced all of the caps in the amp.  This has the Model 340 solid state power amp section.  I didn't take a look at the bias on the output transistors (which seems like a great place to start).  I will be sure to check this out tonight.

I just replaced all of the capacitors in an Earth Sound Research Original 2000 head.  Interestingly enough, once I replaced all of the capacitors the output section of the amplifier now runs super hot.   Any ideas of why this may be?

All capacitor values match design values.   The amp itself has a 4ohm output and I am running it through an 8ohm cab.

My guess is that this may be normal, but I don't remember the amp being this hot before I re-capped it.
