Correction to my post #4 - The coupling capacitors in the AF amplifier are 10uF, the emitter bypass caps are 100uF.

The manual is quite helpful as it gives details of several test parameters for each channel - e.g. insert 120mV rms 1kHz sinewave into the tape input, measure 6.9V rms across 3.2 ohm load applied to speaker outputs. You can do this test initially without dismantling.
