TAPE ADJUSTMENTS
a. Adjusting Azimuth
Be sure to clean the heads before attempting to make any adjustment.
Be sure both channel’s waveform are the same for the phase matching.
Be sure both channels (1 and 2) are the same level using a dual-channel oscilloscope.
After completion of the adjustment, apply the threadlock (TB-1401B) to the azimuth adjustment screws to fix them securely.
Load an azimuth adjustment test tape (VT-f-703 etc., 10 kHz)
in tape deck.
Press the PLAY button.
Use a cross-tip screwdriver to turn the screw for azimuth
adjustment so that the left and right outputs are maximized.
Press the STOP button.
b. Replacing the Head
R/P HEAD
l After replacing the head, demagnetize the head by using a
degausser.
l All wiring should be returned to the original position after work is
completed.
