hey all.. My friend recentally purchased this amp from a local pawn shop and it didn't work.. We tried to return it but the people were like "It worked when it left".. it didn't.. so he is stuck with this amp..

I pulled the back cover off of it, and two of the MOSFETs on the power supply have chunks taken out of them/holes burnt in them, so I want to replace them.. Just need a repair schematic tho... another thingy is when you feed power to it, the LED turns on then fades out, Like the power was applyed then cut off... could this be a side-effect of the MOSFET problem?

Thankyou...
Jude
