The problem im having with this amp is it keeps shorting the powr suply fets within 2 secs with only power and ground hooked up ..

All fets are new drivers test ok.. All gate resistors test fine..

The power supply fets are IRFZ44N's Drivers are C1027 and A1023 Gate resistors are 22 ohms..

Is there a good replacement for the drivers ??

I will try replacing them even though they test ok and see what i can come up with or does anyone have any ideas where to start ?
