OK?..manual is complet and helpfull... for repairing such a old and rare boombox like JVC PCM it is necessary...
;
Super Anleitung. Ordentliche Auflösung. Das ganze noch in Deutsch wäre zu schön. Alle Datenblätter sind sauber Kopiert und alle Leitungswege sind sauber ausgeführt

Thanks God for the internet and thanks for the service like this - proffessional solution on time.

About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.

The downloaded quality was as good as the orignial

Note: Whenever replacing the reel disk, perform the height checking and adjustment.

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.
