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.
 ;
Wszystko w porządku.
Instrukcja czytelna i kompletna.
Dziękuję.
all right!
thank you.

12. Tape Speed Adjustment (DECK 2) Settings : � Test tape : TTA�100 � Test point : TP8(Lch), TP9(Rch) � Adjustment location : SFR1 Method : Play back the test tape and adjust SFR1 so that the frequency counter reads 3000Hz ± 5Hz (FWD) and FWD SPEED ± 45Hz (REV). 13. Head Azimuth Adjustment (DECK 1, DECK 2) Settings : � Test tape : TTA�330 � Test point : TP8(Lch), TP9(Rch) � Adjustment location : Azimuth adjustment screw Method : Play back (FWD) the 8kHz signal of the test tape and adjust screw so that the output becomes maximum. Next, perform on REV PLAY mode. 14. PB Frequency Response Check (DECK 1, DECK 2) Settings : � Test tape : TTA�330 � Test point :TP8(Lch), TP9(Rch) Method : Play back the 315Hz and 8kHz signals of the test tape and check that the output ratio of the 8kHz signal with respect to that of the 315Hz signal is within 5.0dB. 15. PB Sensitivity Check (DECK 1, DECK 2) Settings : � Test tape : TTA�200 � Test point : TP8(Lch), TP9(Rch) Method : Play back the test tape and check that the output level of the test point is 110mV ± 3.0dB. 16. REC/PB Frequency Response Adjustment (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP8(Lch), TP9(Rch) � Input signal : 1kHz / 8kHz (LINE IN) � Adjustment location : SFR451 (Lch) SFR452 (Rch) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP8, TP9 becomes -20VU (-26dBV). Record and play back the 1kHz and 8kHz signals and adjust SFRs so that the output of the 8kHz signals becomes 1.5dB ± 0.5dB with respect to that of the 1kHz signal. 17. REC/PB Sensitivity Check (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP8(Lch), TP9(Rch) � Input signal : 1kHz (LINE IN) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at TP8, TP9 becomes 0VU (-6dBV). Record and play back the 1kHz signals and check that the output is -1dB ± 3.5dB.

18. µ-con OSC Adjustment Settings : � Test point : TP11(KEY-SCAN), GND � Adjustment location : L951 Method : Connect a frequency counter across TP11 and GND via a CR network filter. Then adjust L951 so that the test point becomes 184.94Hz ± 0.18Hz.
