I got one of these amps in and they had the twisted wires switched around on 1 side of the amp . Which blew all of the outputs .
The twisted wires are disconnected from the rectifier side amp still draws excessive current .
Here is what I get on the power supply fets
Scope set to 5us .5 volts/div
The trace was centered before taking pics
If these look good any ideas where to start checking ?

To clarify, I misread. Since you were mentioning the reversed wires for the outputs, I thought that you were referring to the outputs. My mistake.
It looks like the PNP drivers are open or have a bad connection to ground. Is the base drive to the PNP drivers going to ground?
Do you read 0 ohms between the collector of the PNP drivers and ground?
