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 jest OK. Schematy czytelne, opisane niektóre procedury.

Note on Schematic Diagram: � 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. Note: The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. � U : B+ Line. � H : adjustment for repair. � Power voltage is dc 14.4V and fed with regulated dc power supply from ACC and BATT cords. � Voltage and waveforms are dc with respect to ground under no-signal conditions. no mark : CD PLAY � : Impossible to measure � 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. � Signal path. J : CD
