A friend of mine gave me an RD Audio RD-1750.1 amp that would blow fuses as soon as it was powered on. I opened it up and replaced 5 broken MOSFETs (the legs were broken off right at the body) but it still doesnt work. Basically, when I switch the amp on (remote goes high), the protection light comes on for a second, then just as the light goes out, the power light comes on, and the amp goes into dead-short mode (Im using a bench power supply with over-current protection so as not to waste fuses).
Where do I start? Ive looked for anything noticeably broken (burnt resistors, diodes, bulging/leaking caps) but I dont see anything.
