My cousin tried fixing and amp like this. He said he changed a couple of mosfets but it didn't solve the problem. Then he gave me the amp so I decided to take a stab at it. I was hoping someone had the schematic, parts list or picture of the circuit board so that I can confirm he installed the correct mosfets. Any help would be greatly appreciated.

What does the amp do when you power it up?

I wasn't there when he powered it up and its been a couple of years since he attempted this repair so he doesn't remember. I only know that he change two of the fets. I wanted to confirm they were correct before I powered it up and possibly did more damage. The two fets I'm talking about are N2D F10P20F & N2D F10P20FR.

Those aren't FETs, they're rectifiers.

If you insert a 10 amp fuse in the B+ line and have all semiconductors tightly clamped to the heatsink, you shouldn't do any more damage (assuming that the rectifiers are installed in the correct locations - the board should be marked).
