demagnetizer. (Do not bring the head demagnetizer close
to the erase head.)
Do not use a magnetized screwdriver for the adjustments.
3. After the adjustments, apply suitable locking compound to
the parts adjusted.
4, The adjustments should be performed with the rated
power supply voltage unless otherwise noted.
5. The adjustments should be performed in the order given
in this service manual. (As a general rule, playback
circuit adjustment should be completed before performing
recording circuit adjustment.)

Deliver the standard input signal level to the input jack
and set the REC LEVEL control to obtain the standard

2. Turn the adjustment screw and check output peaks. If
the peaks do not match for L-CH and R-CH, turn the
adjustment screw so that outputs match within 1 dB of
