This is a very good quality print (scan) of the original SONY service manual. The original from Sony is on very thin paper. Nevertheless it is very clear and sharp and excellent readable. I'm very satisfied to have now this rare document. I've looking for it many years (infrequent). It contains very detailed circuit diagrams, exploded views, part lists, PCB view with good readable connection lines. Very recommended.

A big deal.
Many thanks !

If "Adjustment could not be executed." of "Fig. 2" is displayed, make readjustment. Even after the readjustment, if "Fig. 2" screen is still displayed, adjust the "MR duty" again and perform "drive frequency and the motor control adjustment" again. However, after all the above, if the adjustment is still impossible, the SWM unit, the fixed tube unit, GMR tape unit, or MR head unit may be defective.
