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

Note: � All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. � All resistors are in � and 1/4 W or less unless otherwise � � � � � specified. ¢ : internal component. U : B+ Line. H : adjustment for repair. Power voltage is dc 3 V and fed with regulated dc power supply from external power voltage jack. Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. no mark : FM 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.
