6. Bias frequency Adjustment

L330 .........................................................................56 kHz ± 2 kHz

7. Tape speed Adjustment

Settings: • Test tape: MT111

• Test point: PHONES JACK (J251)

• Adjustment location: SFR761

Method: Play back the test tape and adjust so that the output

frequency is 3000 Hz ±30 Hz.

8. Azimuth Adjustment

Settings: • Test tape: TTA-320

• Test point: PHONES JACK (J251)

• Adjustment location: Azimuth adjustment screw
