Are there any other issues with the amp?

This amp is two ohm stable if the amp was driving less than a two ohm load, this may have shortened the lifespan of these caps.

I see this from time to time and if there are no other issues, replacing the caps should take care of the problem.
 
This is a common problem. Replacing the outputs and caps should fix the amp. You can replace all the outputs and filter caps, but I don't think it's necesssary.

Again, the failure may be due to the amp being worked too hard.
 
alright do you know a good source for these parts? I got this amp with a lot of others from a pawn shop as they had been returned as broken so i have no idea the past of this amp but i think your right just someone who didnt know what they was doing probly had the gains completely up
 
Here is a link for the IXTQ36N30P's. You may be able to buy them from Allied or Digikey.
IXTQ36N30P IXYS | Mouser

The caps can be replaced with anyting with the same value and same footprint, maybe Nichicon or Vishay.

Or someone else on this forum may be able to recommend a good source. If you can find a spare parts board that would work.

2200UF 25V 105 degree for the filter caps and 10UF 200V non polarized for the caps near the output inductors.
 
This amp tends to run pretty warm,and idle current of 5 amps isn't out of range.The output inductor can withstand a significient amount of heat. If there isn't a thermal gap pad you may consider installing one between the inductor and amp cover.
