Okay, so I did something pretty stupid.

I hooked up a JL w7 subwoofer (3 ohms) to my Onkyo TX-DS939 receiver (8 ohm minimum) to see if the sub worked. It was for a brief amount of time (not more than a couple of minutes).

Now there is a buzzing sound in all channels that goes away once the unit has warmed up. I opened it up and found some smaller caps that are buldging slightly...could that be the problem?

I've repaired car amps before, but never anything like this...

I doubt that the problem happened due to the sub, but still, this was a bad thing to do. Electronics works on a time scale on the order of microseconds. 'A couple of minutes' is by no means a 'brief amount of time', as far as asking for a erious failure, it could as well have been a century.
