Thanks for this "hard to find" service manual. This Sony PS212A is a very good turntable that needed to be restored !
 ;
Excellent quality on these manuals. Same as having the original printed manual and incredibly useful when doing a custom install like me. Keep it up on the good work.
;
This is an excellent information source. Great quality and tons of info regarding technical service for the Technics SH8065.
;
5 stars on this manual since it is the complete version, not the half manual you find free for download all over the web. Good job.

CHECKING AND ADJUSTMENT OF TAKE-UP TORQUE IN REWIND MODE
� Remove the cassette housing control assembly. � After short-circuiting TP801 provided at the center (facing to the main PWB), plug in the power cord. � 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 TAKE-UP TORQUE IN FAST FORWARD MODE
� Remove the cassette housing control assembly. � After short-circuiting TP801 provided at the center (facing to the main PWB), plug in the power cord. � 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 4-9. � 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.
