Service manual made no mention of this adjustment. I adjusted each side for about 30 mV. Measurements were taken across the emitter resistors of the one of the output transistors from each channel. At the end of the video it can be seen that the amount of distortion increased as the bias voltage was decreased. Since the time duration of the distortion is constant, it would make itself more noticeable at lower output levels.
