[QUOTE="smoka, post: 6285090, member: 606721"] I used to intern at an electrical devices company and in my spare time I would bring in my friends blown amps to play around with. I learned a few things but its not easy to work without any schematics... The only help I can offer, is to inspect the amp very carefully, most of the time you will find a burn mark etc where the amp blew. Also its usually one of the transistors that go first so check them well. If it is going into protect, I would guess its a short somewhere in the power supply. If you get the amp to turn on, but no sound. Use a signal gen as an input to the rca's to get a constant source, then use an o-scope to 'follow' the signal through the amp. Again this is just stuff I found while playing around, not very technical, but good luck. [/QUOTE]
