TAPE ADJUSTMENTS
1. Azimuth Adjustment
• Be sure to clean the heads before attempting to make any adjustment.
• Be sure both channels (1 and 2) are the same level.
(Using a dual-channel oscilloscope)
• Be sure both channel's waveform are same for the phase matching.
• After completion of the adjustment, use the threadlock (TB-1401B) to
secure the azimuth adjustment screws.
LID CLOSE KEY
PRESS
1. Open the lid. And press the "Lid Close Key" as Fig.1.
2. Load a test tape (VTT-738 etc. : 10kHz) in the Deck.
3. Press the PLAY button. (Normal playback)
4. Use a + 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. See Fig.2.
5. Press the PLAY button. (Reverse playback)
6. Use a + tip screwdriver to turn the screw for reverse azimuth
adjustment so that the left and right outputs are maximized
at the same phase during reverse playback.
7. Adjust so that the waveforms for the left and right channels are in alignment.

2. Tape Speed Adjustment
• Connect the Frequency Counter to TAPE OUT.
1. Insert the test tape (MTT-111N, etc.; 3,000Hz) into the DECK.

hole for adjustment
2. Press the PLAY button. .
MOTOR
3. Adjust a hole on the motor bottom so that a frequency counter reading of 3,000
±5Hz
is obtained.See Fig.3.
4. Press the STOP button, and eject the test tape.
