Hi all,
I scabbed this baby up from our local council cleanup. Both
channels are blown up - ie driver transistors are SC collector to emitter.
Does anyone know what the bias current should be so I can set it up after
repairs. (Otherwise I'll get a manual form HCSD)

Thanks
Giles

**I don't have a manual for the 3900Z, but based on other, similar Sansewer
amps, you should be safe around 10mA per output device.
