Working on an audio pipe amp. All output were burned up and drivers shorted. Replaced all the drivers. Checking drive signals before installing outputs. I have what looks like ringing on the 5 volts to the high side drive. The ringing follows all the the way out to the high side drive on the outputs. Is this normal? I put one output on each side to test and it shorted them as soon as I powered the amp. I have good signal on the driver board itself.
