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 !

� Color Tuner: TU200 TEPB5-02 Selects a desired radio wave and changes it to the video IF signal. � Video IF Amp.: Q200 2SC4670 Amplifies the video IF signal output from the tuner TU by 10 times (20 dB). � Video Det./Sound Det./FM Det./AFT/AGC: IC200 M51348FP Eliminates the carrier wave in the video IF signal, and picks up the video signal and the sound IF signal. Also, the sound signal is picked up from the sound IF signal by FM detection. � Audio Amp.: IC600 NJM2070M Sound amplification. � Chroma Circuit: IC300 IR3P96B Generates the tricolor (red, green, and blue) from the video signal. � Display Control/ Auto-Tuning Control : IC700 MSM6770GS Controls the display. � Tuning Voltage Generator: IC270 BA10358F Generates the tuning voltage with the tuning pulse (TU) output from 6.
