7) Finally re-check the tape speed.
Caution : Cool the patterns down to normal tempera-
ture after soldering. If the pattern remains
heated,the gorvernor circuit does not
operate normally.

1. AM IF Adjustment
IFT201..................................................................450kHz
2. AM VT Check
Settings:  Test point: TP1 (VT)
Method: Set to AM 530kHz and check the TP1 is
1.0V-0.2/+0.3V. Then set to AM 1710kHz
and check the test point is less than 10.0V.
3. AM Tracking Adjustment

Settings: Test point TP1(VT)
Adjustment location ................................................L204
Method:` Set to FM 59.75MHz<591YU>,76MHz
<EXCEPT 591YU> and adjust L204 so that
the testpoint becomes 0.9V±0.1V. Then set
to FM108.1MHz and check that the test
point is less than 12.0V.

6. TV VT Adjustment<591YU ONLY>
Settings: Test point TP1(VT)
Adjustment location ................................................L203
Method: Set to TV 2ch and adjust L203 so that
the test point becomes 1.0V±0.1V. Then set
to TV13 ch and check that the test point is
less than 12.0V.

9. GOVERNER 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 beginning
of the tape-run, perform this adjustment following the
procedures below.
1) Solder resistor pattern 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 beginning of the
tape-run.

8. Tape Speed Adjustment
Settings:  Test tape : TTA100
 Test point : HEADPHONE (J001)
 Adjustment location : SFR101
 Supper BASS: OFF
 Tape select: NORM
 Direction: FWD
 Volume: MAX10dB
Method: Play back the test tape and adjust for
3000Hz±60Hz (FWD) and confirm the
the test tape 3000Hz±60Hz (RVE).

5) When the rise of tape running is smooth, no more
adjustment 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.
