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 L206.....................................................................630kHz CT202<591YU ONLY>................................... 1440kHz CT201...............................1440kHz 4. FM VT Adjustment Settings: Test point TP1(VT) Adjustment location ................................................L204 Method:` Set to FM 59.75MHz<591YU>,76MHz 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.

Tape Speed Adjustment Settings: Test tape : TTA100 Test point : HEADPHONE (J001) Adjustment location : SFR101 Supper BASS: OFF Tape select: NORM Direction: FWD Volume: MAX10dB Method: Play back the test tape and adjust for 3000Hz±60Hz (FWD) and confirm the the test tape 3000Hz±60Hz (RVE). 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.
