Very good service and quick service, very good quality of service manual!
;
Great tape deck manual!
I'm very positively surprised, because it is a very long manual, lot of pages, drawings, diagrams, description of how to make the alignment and adjustment procedures.
It is as good as the old "Naka" manuals from the 1970's - if somebody have seen them, they know what I mean by that.
I recommend to buy this very much !

Detailed schematic diagram, manual for professionals
IC description
Pin 65 - GY Analog Green/Luma Input This input pin takes the AC-coupled analog compinent signal Green or Luma. The amplitude is 1.0V maximum at 75 Ohms and a couplign capacitor of 220nF. Internally, the DC-offset of the input signal is adjusted via the programmable internal clamping circuit. Connect to ground if not used.
Pin 66 - GNDGY Analog Ground This is the ground pin for the A/D converter of the Green or Luma signal and must be connected to ground. Note : All ground pins of the chip(i.e. 18,52,58,60,62,64, 66, and 68) must be connected together low rresistive. The layout of the PCB must take into consideration the need for a low-noise ground.
Pin 67 - RV Analog Red/V Chroma Input This input pin takes the AC-coupled analog component signal Red or V Chroma. The amplitude is 1.0V maximum at 75ohms and a coupling capacitor of 220nF. Internally, the DC-offset of the input signal is adjusted via the programmable internal clamping circuit. Connect to ground if not used.
Pin 68 - GNDRY Analog Ground This is the ground pin for the A/D converter of the Red or V Chroma signal and must be connected to ground. Note : All ground pins of the chip (i.e. 18,52,58,62,64,66, and 68) must be connected together low resistive. The layout of the PCB must take into consideration the need for a low-noise ground.
