This amp is PC-0695-C.1
It came in with 2 shorted outputs in the 2 series channel.
I replace all 4 in the channel, all gate resistors and source resistors tested fine.
Power up the amp it draws 40amps current. If I remove Q243 and Q246 the amp powers and idles fine but R257 gets smoking hot because of the rail dc on the output terminal.
I only have 13.50vdc on the source pad of these 2 outputs. I should see full rail voltage.
I have +31.92vdc with these 2 outputs removed on the bridging terminal of the 2 series channel.
Anybody have any ideas?
