jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.
Instrukcja bardzo czytelna. zawiera co potrzeba. Polecam

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.
