My manual showed up and I got a good meter.
The DC balance adjusted with VR1 and VR2 measures:
L 5mV
R 0mV
VR3 and VR5 adjust within specs at 56 and 70mV
VR4 and VR6 start at 136mV with both pots fully counterclockwise and only increases with any attempt at adjustment.
I have noticed that the transistors Q1 and Q2 are ECG033(black) and Q5 and Q6 are ECG034(green) while the ones at Q3 and Q4 are 2sc2526(black) and Q7 and Q8 are 2sa1076(green). The replacements (ECG033 and ECG034) are on the heatsink that gets really hot.
