6. Azimuth Adjustment
Settings : Test tape : TTA-320 (TTA-3.30)
Test point : PHONES JACK (J101)
S-BASS : OFF
TAPE SELECTOR : NORMAL
VOLUME : MAX
Adjustment location : Azimuth adjustment
screw
Method : Play back the 8kHz signal of the test tape and
adjust so that the output becomes maximum.
7. Tape speed adjustment
Settings : Test tape : TTA-100 (TAPE CENTER)
Test point : PHONES JACK (J101)
Adjustment location : SFR101
Method : Play back the test tape and adjust for 3015 ± 10 Hz.
8. GOVERNOR 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.
Ifwowisconspicuousatthebeginningofthetape-run,perform
this adjustment following the procedure below.
1) Solder only medium resistor pattern (B) of the MOTOR
AND GOVERNOR MATCHING ADJ. resistor group.
2) Set the tape speed (using speed adjustment SFR).
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)Whentheriseoftaperunningissmooth,nomoreadjustment
is necessary.
If wow continues for 1 to 2 seconds at the rise time, change
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 patterns down to normal temperature
after soldering. If the pattern remains heated,
the governor circuit does not operate normally.
