Default Realistic SA-2001 Integrated Amplifier

I have an old (circa 1978-82)Realistic SA-2001.Does anyone know what the bias voltage for the 2 trimpots should be set for and where to read it?A schematic doesn't look like it's around.

Hi Aquarium,
Read the voltage drop across the two emitter resistors on each channel. Divide by the resistance and that's your current. How close are they?

I probably don't need to adjust the bias voltage right now.I am using the unit anyway and the DC readout from the speaker terminals seems O.K. Under 15mv each side so for now it's alright.I was hoping to get some info on this unit but this seems scarce.
