Good afternoon everyone, on this occasion I am urging you to repair this Kicker brand amplifier model ZX1000.1 REV 2.1. At the beginning, damage was found in the power supply, it has already been recovered and in the output stage there is an auxiliary supply that was damaged, the 2 htp18n06g were replaced and the 1n4002 diode is already oscillating, but now I have stopped at the driver card, I already managed to get it to turn on and stay on, I don't have any pulses in the output fets, I mention that I have the fets outside the board since if I leave them inside they won't stay on, greetings

To clarify, you have a triangle wave on pin 4 and 0v DC on pin 3? Yes
DCV on the two output terminals of the LM361? Pin 9. 4.64v Pin 11. 0v
DCV on the 4 PS terminals of the LM361?
Pin 1. 15.36v
Pin 6. -15.35v
Pin 14. 2.6 with reference to pin 10 and 4.9v with reference to gnd

If 8, 13 and 14 are all 5v above pin 10, you have ±15v on the supply terminals 1 and 6 and the triangle waveform is constantly crossing the voltage on pin 3 (both read 0v DC), you should have a square wave output. If not, that would tend to indicate that the LM361 is defective.
Are you saying that pins 9 and 11 only connect to those diodes?
If the amp won't stay on with the outputs in the circuit, you won't be able to do any further troubleshooting.
Do you think the problem before could simply have been dirty contacts on the driver board connector?
