Bardzo dobra jakość skanu, przystępna cena. Instrukcja serwisowa okazała się przydatna przy "reanimowaniu" dwudziestoparoletniego decka, który teraz pięknie gra :)
Documentation made available quickly and It is good quality. Thanks.

C : panel designation. U : B+ Line. Power voltage is dc 3 V and fed with regulated dc power supply from battery terminal. Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. Voltages and waveforms are dc with respect to ground in playback mode. no mark : FM (RADIO SECTION) PLAY (TAPE SECTION) ( ) : AM Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. Circled numbers refer to waveforms.
