I have a Randall Warhead 1st generation that worked great, but a few months ago I noticed the amp started to lower in volume and "fizzle" out while I was playing. Now, nothing comes out of the speakers period. I have the matching cabs so made sure impedance wasn't the cause.  I have cleaned all jacks and even tried a patch cable on the send/return.

The amp powers on OK, the only way I can use the amp is if I plug the effects loop send into another power amp.

On a side note, the only sound that can be heard is If I turn the volume knobs to max, I can barely "hear" the amp through the speakers, just NO volume whatsoever.

I'm guessing caps or transformer?  It just worked and then fizzled while I was playing one day.

Anyway, I appreciate your time if you have any advice.
