Forte Model 5

[Andrewc556]

Does anyone have a schematic for a forte audio model 5? I'm trying to fix a problem with one that has a large dc offset in one channel(1.5 volts) and the bias on the output transistors is unstable. As well, does anyone know the correct bias current for the output stage? The working channel is biased around 100 mA. It's using GT20D201/GT20D101 IGBT's.

Thanks

There were never any schematics released for these Forte amps from what I have been told.

They were past my time.
