Default Soundstream USA100 one channel dead

I have a USA100 sitting here with a fault somewhere in the signal path.
One channel has input on the FEB, the other hasn't.
I don't even have a signal at the dead channel's gainpot.

Because of the US-Flag silkscreen it's way hard to follow the traces.
So a schematic would be very helpful!
If anybody has some infos on this one or any other USA-Series amp I would be very thankful if I could get a copy!


Regards Julian
