TAPE ADJUSTMENTS
1. Remove the cover deck 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.1.
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.

•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.

3. Torque Measurement
• Connect the Frequency Counter to TAPE OUT.
1. Insert the test tape (MTT-111N, etc.; 3,000Hz) into the DECK.
2. Press the PLAY button. .
3. Adjust a hole on the motor bottom so that a frequency counter reading of 3,000
± 5Hz is obtained.See Fig.2.
4. Press the STOP button, and eject the test tape.

PRODUCT SAFETY NOTICE
Each precaution in this manual should be followed during servicing. Components identified with the IEC symbol !
!! in the parts list and the schematic diagram designated components
in which safety can be of special significance. When replacing a component identified by !
!! , use only the replacement parts designated, or parts with the same ratings of resistance,
wattage or voltage that are designated in the parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably
insulated from the supply circuit before returning the product to the customer.

SCHEMATIC DIAGRAM (AMPLIFIER)
This is a basic schematic diagram.
PRODUCT SAFETY NOTICE
Each precaution in this manual should be followed during servicing. Components identified with the IEC symbol !
!! in the
parts list and the schematic diagram designated components in which safety can be of special significance. When replacing
a component identified by !
!! , use only the replacement parts designated, or parts with the same ratings of resistance,
wattage or voltage that are designated in the parts list in this manual. Leakage-current or resistance measurements must
be made to determine that exposed parts are acceptably insulated from the supply circuit before returning the product to
the customer.
