MEASUREMENTS
AND
ADJUSTMENTS
English
e Arm-lift height adjustment
The arm-lift height (distance between the stylus tip and
record
surface
when
the
cueing
control
is
set
to
the
‘'
¥”
position) has been adjusted at the factory to approximately
5 mm (3/16). (Fig. 10)
If
the
clearance
is
too
narrow
or
too
wide
(because
of
different
cartridge
dimensions,
for
example),
turn
the
adjustment
screw
clockwise
or
counterclockwise.
(See Fig. 11)
Clockwise rotation
—distance between the record and stylus tip is decreassed.
Counterclockwise rotation
—distance between the record and stylus tip is increased.
e Adjustment of automatic return position (Fig. 12)
1. Put the stylus protector on the cartridge.
2. Take off the rubber cap covering the adjustment screw
section
and
move
the
tonearm
toward
the
center
of
the
record.
Then,
the
auto-return
position
adjustment
screw
will
appear.
If the tonearm tends to return to the arm rest before the
play has finished,
—turn counterclockwise.
If the tonearm fails to return after the final groove,
—turn clockwise.
e@ Overhang adjustment (Fig. 13)
15 mm is the correct overhang for this tonearm.
Loosen the screws and move the cartridge forward or
backward until the distance between the stylus tip and the
plug becomes 52 mm (2-3/64”).
Tigthen the screws without moving the cartridge.
Adjust the horizontal zero balance, stylus pressure and arm-
lift height whenever you change the cartridge.

e Adjustment of rotational speed
After replacement of drive IC (1C101) and variable resistors
(VR202, 203) or when the rated speed is not obtained by
tuning the pitch control knob, perform the adjustment
according to the following procedure.
1. Remove the bottom board. (Refer to ‘‘Disassembly
Instructions’’.)
. Place the set on the player repair table.
. Put on the record and play.
. Push the speed selector button to ‘45 r.p.m.”.
. Turn the pitch control knob to central position.
(See Fig. 14)
. Adjust VR202 by the screwdriver from under the set
until the rated speed (45 r.p.m.) is obtained while check-
ing it through the stroboscope. (See Fig. 15)
. Push the speed selector button to 33 r.p.m.”.
8. Adjust VR203 by the screwdriver until the rated speed
(33-1/3 r.p.m.) is obtained while checking it through
the stroboscope. (See Fig. 15)
9. After completing the above-mentioned adjustment,
check that the rated speeds can be obtained by pushing
the speed selector button.
Note: Be sure to perform the adjustment of 45 r.p.m. first.
10. As a simple method, it is also possible to adjust VR202
and VR203, removing the turntable. (See Fig. 16)
