Blown Threshold S/300 Stasis II

I over drove it tonight and it went quiet without warning.The on/off light works.
I was really pushing it but I heard no distortion or clipping.I've never played it this loud,but I feel I still had head room.
Im using a re-built Dynaco ST-70 on top.
The Dyna seems fine.
The Threshold has a breaker for a on/off switch but I didnt notice if it had tripped.
One thing I did notice,is the left channel heat sinks were considerably warmer (not hot) than the right channel heat sinks.
Anyway,the amp is dead quiet.
Could it be the breaker/on/off switch 'burned' and a simple replacement may cure the problem?
Or am I in trouble?
Thank you for any advice.

I used to have a forte amp that I believe was made by threshold. Inside that amp each channel had 2 fuses.
Try taking the top off and see if they are blown. If so, you might find replacements at radio shack.

Perhaps you should listen to music without blasting out your eardrums and your masterpiece Threshold amp? Even so, I can't imagine driving this amp to failure. Check fuses and/or preamp.
