Measure across the emitter resistors (.33ohm/3W) Rm81 & 83 for the left channel and Rm82 & 84 for the right channel. See the service manual p9, bottom left corner diagram "Measurement of Bias Current". If you look closely at the diagram you'll see they even converted mA to Mv.
More info here on the mA and mV thing - they told me there would be no math!
Good job by the way on getting it up and running!
