Ground Zero PLUTONIUM GZPA 1.8000D Blowing output fets random

Hi all!

I have been working on the amplifier for a couple of days and have a problem with starting it "cold" as soon as I turn it off. Starting it for 5-6 seconds wouldn't oscillate twice out of ten. if it has a final stage (IRFP360LC) then it will unfortunately shoot you.
I have already replaced IR2113 on it. If you go then you can unwind completely, do not collapse. What can cause it?

It won't be the driver it will be the NAND gates not having enough dead time.
Without a schematic, not a lot more I can guess on.

Going with the DLM4000a controller, this information is missing

Are you connecting or disconnecting from DC power instead of AC power?

It has been tested with a 14v 43A power supply with adjustable current limit. I simply turn on / off with Remote

You might need to force a power-on reset for the controller.
