I have a TMA 500.1 and when i got the amp the fuses and the power stage mosfets(irfz44n) were blown. I removed the blown fets and checked for shorts and found none. Then checked the gate resistors and they were good. Replaced all the power stage fets and checked again for shorts. No shorts. Applied power to the amp and immediately the power fets were blown. Any ideas???
