ADJUSTMENT

(b)Adjustment

Assemble the tape deck into the radio set. (As the tape

speed will vary a little depending on the radio set, the
speed should be adjusted with the radio set in which the
deck is actually used.)

Connect the output to the frequency counter, and play the

test tape mentioned above with the deck set in FOR-
WARD mode.

Insert a screwdriver into a speed adjusting hole of the

motor, and rotate a little so that its tip enters VR for
adjustment.

Rotating slowly the screwdriver CW or CCW, adjust the

frequency to 3 kHz.

3.1.2  Azimuth Adjustment

(this adjustment is necessary if head was replaced.)

(a) Tools required

Test tape

1

ABEX TCC-153(10 kHz)

2

Mirror tape such as TEAC MTT-902

Screw locking bond 

(b) Adjustment

Playing the mirror tape in FWD mode, rotate screw 

A

and 

B

so as to eliminate a curl at the guides on both

ends of head while looking into the mirror.

Play the tape in REV mode. and make adjustment in the

same manner.

Connect the head output to electronic voltmeter, and

insert the TCC-153 tape. Play the tape in FWD mode,
and search the point where the output becomes maxi-
mum while rotating the screw

A

. Then, play the tape in

REV mode, make adjustment in the same manner while
rotating the screw

B

.

Further, reverse the tape, and in FWD and REV modes

respectively, search the point where the output of L and
R channels becomes maximum.

To lock the screws, apply the bond to periphery of both

screws.

3.1 Adjustment

3.1.1 Tape Speed Adjustment

(this adjustment is necessary if main motor was replaced.)

(a) Tools required

Test tape ABEX TCC-112 (frequency 3 kHz)
Ceramic screwdriver (tip 1.2mm)
Frequency counter
Radio set
