The unit most likely blew up a capacitor. If you look in through the slots on the top of the unit you should see 2 big black caps (C6901 and C6902) with shiny silver-ish tops. I should also point out that you probably flew up a 125v 8A (F901) glass fuse on the board that the AC cord plugs into. The glass fuse can be found at Radio Shack, but the caps are a bit more troublesome to find. They are 10,000uF 69v and thats just not a standard part, so you may need to up the voltage requirement and buy a 75v cap. Total to fix the amp yourself: Should be about $35 with shipping.

Might be over heating. Make sure you don't have anything sitting directly on top of it. I even put a little fan blowing outward at the back of my system to keep it cool.
