I've got one of these too, although not from the same seller - mine has the tuning meter. It works well but is near-dead on FM. This, it seems, is a common fault. I think it might be a faulty capacitor in the IF strip, but haven't summoned up the enthusiasm to dig any further. I also have another one in for repair with the same symptoms, only this one might have a tuner fault *as well* 
While I've searched and read the threads on other forums, if anyone has any other insight I'd be glad to hear from you
BTW, does anyone have *really* good quality scans of the schematics? The various copies I'm working from are a bit hit and miss. Of course, the model was changed several times during its long life, which doesn't really help... I haven't looked at these for a few months now - but I remember thinking that the AM/FM switching was done in an interesting fashion: using DC voltages to switch via diodes and transistors rather than putting the audio through the contacts on the turrets...
Cheers,
Mark
