5. Replacement and Adjustment of the Heads
1. Replacing the Head
2. Azimuth Adjustment
If the
azimuth
adjustment
standard
tape
is not
available, play a music cassette. When treble response
becomes optimum,
set the adjustment screw.
After
this adjustment, the screw (2) should be locked with a
bond.
6. Main Adjustments
If adjustment is needed, take the following steps.
Recording:
1. Slide the volume
control knobs
for both right
and left channels
so that the volume will be at
maximum.
2. Apply a signal to the microphone jack, and check
Fig. 12
to see if the meter needles deflect.
3. If both meter needles will not swing evenly, adjust
the semi-fixed resistors ((3) and @) alternately so
that both needles deflect evenly (See Fig. 12).
Turning the resistor in the direction of the arrow
makes
the needle
swing far.
For precise adjust-
ment, it is advisable to connnect a 100 22 resistor
across the head, and adjust the semi-fixed resistors
