This was a bit of mess when I got it! The faults were:
Tuner not soldered in correctly - no AM!
Tuner cogwheel assembly had no backlash tension
Channel control transistors soldered in the wrong way
Tuning photo-detectors failing
stereo mpx mis-adjusted
stereo lamp blown (replaced by zener+led)
very very dirty - nicotine cleaned off with alcohol
