I bought one of these as an Ebay fixer-upper very cheaply. Amazingly it had a production build fault that meant no panel lights came on. The main pcb could also be configured SU-Z100 (not sure about the differences) and that's where the screwup came about. The panel leds are all powered from a current reg TR (Q801) but the current setting resistor (R803) only connects one end. Just link the free end to D802 cathode. The area around Q801 had got quite hot so resoldering and wire linking were necessary. I changed D802 zener to 10V ( D802 measured 13-14V on ext test) to set current to 20mA - the rating of the leds. The lower part of the rectangular display has no leds because the pcb was missing. You can see where it clips in but it's not there and not in the partial schema. Obviously not fitted at the factory. There were no other probs (even the slider pots are as new) except the plastic front assembly which is VERY weak where plastic arms support the pcb and top cover. I removed a collection of little plastic bits. None was critical. It is well worth the effort / expense of restoring one of these. The audio quality is simply excellent. Curiously it retains 1970s mechanical switches while incorporating state of the art IC electronics, inc the main amps.
A low-volume stop-gap before digital switching became the norm and a valued addition to my collection. Recommended.
