Up to now you are the BEST! Prompt-efficient and so reasonable ! I have been after SONY service manual for quite some time !Thank you very much ! I can recomend your service to
all my collegagues ! V.Bergfield .

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 complete manual with all the needed details of calibrations and service instructions about the radio receiver.
A big deal.
Many thanks !

Notes: 1. Hold the torque gauge by hand so that it is not moved. 2. Do not keep the reel disk in lock state. Do not allow long-time measurement.

CHECKING AND ADJUSTMENT OF TAKEUP TORQUE IN REWIND MODE
• Remove the cassette housing control assembly. • After short-circuiting TP7701 and TP7702 provided at the left on the main PWB, plug in the power cord, then turn on the power. • Setting 1. Set a torque gauge to zero on the scale. Place it on the supply reel disk. 2. Press the rewind button. 3. To calculate the remaining capacity, slowly rotate the take-up reel disk, and then shift it into the rewind mode. • Checking 1. Turn the torque gauge slowly (one rotation every 2 to 3 seconds) by hand in the CCW direction. 2. Make sure that the indication of torque gauge is not less than 30mN·m (306gf·cm).

CHECKING AND ADJUSTMENT OF TAKEUP TORQUE IN FAST FORWARD MODE
• Remove the cassette housing control assembly. • After short-circuiting TP7701 and TP7702 provided at the left on the main PWB, plug in the power cord, then turn on the power. • Setting 1. Set a torque gauge to zero on the scale. Place it on the take-up reel disk. 2. Press the FF button. 3. To calculate the remaining capacity of the play back mode, slowly rotate the supply reel disk, and then shift it into the forward mode. • Checking 1. Turn the torque gauge slowly (one rotation every 2 to 3 seconds) by hand in the CW direction. 2. Make sure that the indication of torque gauge is not less than 30mN·m (306gf·cm).

Figure 1-8. • Adjustment 1. If the FF winding-up torque is less than the specified value, clean the capstan D.D. motor pulley, drive belt, and limiter pulley with cleaning liquid, and check again. 2. If the torque is less that the set value, replace the reel belt.
• Adjustment 1. If the rewind winding-up torque is less than the specified value, clean the capstan D.D. motor pulley, drive belt, and limiter pulley with cleaning liquid, rewind again, and check the winding-up torque. 2. If the winding-up torque is still out of range, replace the drive belt.
