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.

10. Head Azimuth Adjustment (DECK 1, DECK 2) Settings: Test tape: TI�A-300 �* Test point: TP8(Lch), TP9(Rch) Adjustment location: Head azimuth adjustment screw Method: Play back (FWD) the 10kHz signal of the test tape and adjust screw so that the output becomes maximum. Next, perform on REV PLAY mode.

13. REC/PB Frequency Response Check Settings: Test tape: �ITA-615 (Normal) � Test point: TP8(Lch), TP9(Rch) Input signal : 1kHz / 8kHz (LINE IN) Method : Apply a lkHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP8(Lch), TP9(Rch) becomes 8-10mV. Record and play back the lkHz and 10kHz signals and check that the output is OdB a 4,0dB.
