Are any other capacitors melted/deformed (other than the output filter caps)?

Not that I could see, I'll take another look when I get home.
Any idea what may have happened or is this fairly normal?

If this resistor and capacitor are in series and connected across the speaker output, they were damaged when the larger filter capacitors failed.


The larger filter caps were likely damaged by abuse or the wrong speaker load impedance.

I'm not sure what could have happened, the amp hasn't seen anything lower than an impedance of 4. Havent pushed the amp at all and it always stayed really cool.

It's possible that the inductors have shorted turns. That would have caused excessive ripple on the caps. I haven't seen it yet on this amp but I haven't repaired many yet either.

Is the capacitor in series with the resistor and connected across the speaker output terminals as I described?

i've also mostly seen those large caps swell up, and even explode in the cold alaskan winters, mostly hand-in-hand with a discharge. just like what happens to a battery. almost always, this shorts the plates inside and fries other things. only single time i avoided damage to the circuits is when the caps were displayed and i knew not to power it up
