I replaced the driver transistors and those two diodes including D5 same 2.20 volt on all 6 gate pads.
Is it possible LM317T and LM337SP could be faulty? The amp will power on still but I noticed both regulators get extremely hot. And the outputs got hot too.
Are all of the heatsink mounted components tightly clamped to the heatsink? If not, clamp them. Does the amp work properly?
Ok I just put th amp back in the heat sink clamped all the transistors amp does power on and plays audio on one of the channels amp doesn't appear to be drawing excessive current or getting hot. I also checked the gate pads again and there is 5 volt on all six even with two IRF3205's installed for testing. The MTP50N's are still good should reinstall those or just replace all six with 3205's?
Are you saying that one channel is dead?
Replace all of the PS transistors with 3205s. If the PS gate resistors are greater than 51 ohms, replace them with 47 ohm resistors.

And does that resistor '1002' connect to anything? I bridged the connection. The other channel plays audio now but it's staticky.
