Setting the bias for the power amp section of an audio ...
https://electronics.stackexchange.com/questions/289929/setting-the-bias-for-the-power-amp-section-of-an-audio-amplifier
the power amp section is really the output stage (OPS). The input and vas stages are in the driver circuit. the ops is quite innovative. to check bias of it, measure voltage across j/m -> should be around 4v -> 6 pn junctions.
