ADJUSTMENT
<TAPEPLAYERSECTION>
1. Motor load adjustment.
Perform the STOP−>PLAY and REVERSE operations ( or
PAUSE ON−>OFF ) after the motor is replaced. When the
tape starts running smooth, this adjustment is not necessary.
If wow is conspicuous at the begining of the tape-run, perform
this adjustment following the procedure below.
1) Solder both resistor pattern (B) and (C) of the MOTOR
AND GOVERNOR MATCHING ADJ. resistor group.
2) Set the tape speed (using speed adjustment SFR101).
3) Restrict the motor rotation by hand (or turn PAUSE ON).
4) Remove your hand and listen to the begining of the tape-run.
5) When the rise of tape is running is smooth, no more
adjustment is necessary.
If wow continues for 1 to 2 seconds at the rise time, reduce
the combined resistance according to procedure 6 and check
that the tape starts running smooth.
6) Solder the resistor pattern according to the table below.
7) Finally re-check the tape speed.
Caution : Cool the pattern down to normal temperature
after soldering. If the pattern remains heated,
the governor circuit does not operate normally.
