ADJUSTMENT
1. AM IF Adjustment L205 ................................................................. 450kHz 2. AM VT Check Settings : · Test point : TP1 (VT) Method : Set to AM 530kHz and check that the voltage at the test point is within 0.8V ~ 1.5V. Then set to AM 1710kHz and check that the test point is less than 10.0V. 3. FM VT Check Settings : · Test point : TP1 (VT) Method : Set to FM 76.0MHz , 87.5MHz and check that the voltage at the test point is 1.1V ± 0.3V , 2.3V ± 0.5V . Then set to FM 108.0MHz , 108.1MHz and check that the test point is less than 11.0V. 4. AM Tracking Adjustment L203 ................................................................. 630kHz TC201 ............................................................. 1440kHz 5. FM Tracking Adjustment L201 .............................................................. 87.5MHz
6. Tape Speed Adjustment Settings : · Test tape : TTA100 · Test point : Phones Jack (J101) · Volume : MAX · Adjustment location : SFR401 Method : Play back the test tape and adjust SFR401 for 3010Hz ± 10Hz (FWD). Then confirm WOW is less than 0.52%.
