TAPE ADJUSTMENTS

a. Replacing the head

1. After replacement, demagnetize the heads by using a degausser.

2. Be sure to clean the heads before attempting to make any adjustments.

3. Be sure both channels (1 and 2) are the same level. (Using a dual-channels oscilloscope).

4. All wiring should be returned to the original position after work is completed.

c. Adjusting motor speed

1. Insert the test tape (MTT-111 or etc. 3,000 Hz).

2. Press the PLAY button.

3. Use a flat-tip screwdriver to turn the SVR to adjust so that the frequency counter becomes 3,000 Hz.

4. Press the STOP button.

d. Replacing the motor

MOTOR SPEED ADJUSTMENT

b. Adjusting head azimuth

1. Load a test tape (VTT-738, etc. :10kHz) for azimuth adjustment.

2. Press the PLAY button.

3. Use a cross-tip screwdriver to turn the screw for normal azimuth adjustment so that the left and right outputs are maximized at the same phase during normal playback.

4. Press the STOP button.

e. Checking the mechanism torques

• Clean the head, capstan and pinch roller before making any measurement.
