So I had this amplifier I purchased with some shorted output transistors. And the power supply was completely burnt crispy. 22r gate resistors and maybe 80n70's were in the power supply.
I removed the bad output transistors (irfp4229) and ordered 8 new ones on mouser or equivalent.
Removed and replaced all burnt driver transistors, mosfets and replaced al the gate resistors with 47R as I was going to use irf3205's.
The unit runs the 4 torridal, 4bank setup in the power supply.

Drive at the gates resistors.
When I place one fet in each bank (rectifiers removed) the fets heat up in seconds. Draws 3amps of current at idle.
Do I need to use 2 fets per bank as each has a individual push and pull?
