Accuphase P-300S

I recently got an Accuphase P-300S, and there is no service manual or schematic available for this model. Does anyone know what the factory setting is for bias voltage (or current)?
Thank you.

The only thing I can find is that the P-300S is rated for 100 Watts power consumption with 0 signal input. With power=current*line voltage, measure the input current and set the bias so that you're drawing 100 Watts. At 120VAC about .833 amps.
