I got this hitachi hca/hma 8500 set it worked then the meters shot straight up and now in protection and stays there. I've checked offset was good. bias was fine. Pulled both amps out nothing so Im pretty sure mosfets are fine. I'm suspecting one of the 32 fuse resistor or blown amp is full of them.Im just not sure of the best way to go forward while keeping those mosfets safe
