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.

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