I have the punch that has completely obliverated the power supply and 2 shorted output transistors. I have drive still on all the ps gate signal. My question is does this amp have 16ohm gates in q1004, Q1003, and Q100? Are they the same fet 75344G?. Q1000, Q1002, Q1005 have the normal 60.5ohm. the outputs are IRFP260N. I can't believe the drivers survived or ic. They complete burnt the mosfets off the pads.

Ok I got them from mouser. Just making sure. The ps burnt up so bad and only two of the output failed. Since it has a all new ps, it will have all new fets in the output stage as well. I can see the drive signal when I probe the output drive board and a triangle wave on one pin. But not at output transistor locations.
