SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the
power cord is less than 460 kohms, the unit is defective.
Some illustrations using in this service manual are slightly different from the actual set.

ASSEMBLY
1. Remove the main unit with the packing from
the box and take off the packing.
2. Set the 45-rpm adaptor on the main unit as
shown in the diagram.
3. Insert the turntable onto the center spindle.
4. Set the belt on the driving pulley. (The belt is
wound on the turntable.)
5. Set the turntable sheet on the turntable.
6. Remove the tie securing the tonearm.

CONNECTIONS
1. Connect the left (white) and right (red) output cords respectively to your amplifier’s PHONO jacks
etc .
2. Connect the ground wire to the amplifier’s signal ground terminal.
3. Plug the power cord into a wall outlet. (Or if the amplifier has power outlets, plug it in there, but
before doing so, read the amplifier’s manual and check that the capacity is sufficient.)

CARTRIDGE REPLACEMENT
(The cartridge forms a single body with the head shell. Use the following procedure to replace it.)
1. Remove the screw on the bottom of the head
shell sa shown in the diagram.
Screw (philips) small
Screwdriver
(philips) small
Desk, table, etc
2. Rotate the entire head shell gently in both directions.
The neck of the head shell is attached to the pipe
arm.
Turn it gently until the shell comes loose.
3. Carefully remove the head shell.
(Be careful not to break the lead wire.)
4. Remove the tip of the lead wire from the carridge terminal.
5. Install the new cartridge (with head shell).
The polarities are as shown on the diagram.

METHOD OF ADJUSTMENT
1. Relationship between belt and pulley.
Check that the belt is not touching the collars
(A) of the motor pulley. If it is, remove the turntable and reattach the belt at the center of the
turntable skirt.

2. Speed adjustment
If the speed is off, adjust it with the variable
resistor on the motor control board.
Adjust for 33 r.p.m first, then set at 45 r.p.m
and check.
After adjusting, check the two speeds (33 and
45 r.p.m) once again.
This diagram shows the bottom panel.

4. Stylus tip height adjustment
(1) Adjust the stylus tip height under standard
conditions.
(Standard conditions: with the turntable,
turntable sheet, and record set)
(2) The styus tip height should be adjusted to
about 6mm when returned (5-7mm at the
outermost position for 17cm records).
Foot
3. Lead in and lead out adjustment
(1) Lead in
(Test record: Hitachi HT-5 (30cm))
Check that the stylus lowers at 5 to 25
counts for both 17 cm and 30 cm records.
(2) Lead out
(Test record: Nippon Columbia EM-1001
(17cm))
Check that the pickup returns at 3 to 15
counts (3mm pitch).
If the counts are off , adjust as follows:
(a) Fasten the pickup to the arm rest.
(b) Insert a screwdriver into the lead in or lead
out adjustment holes and adjust.

(3) If the stylus tip is too high, sound may be
distorted and the stylus may not advance.
If it is too low, it may scratch the record
when returning.
(4) Adjust using the lifter screw.
Turn clockwise to lower the stylus tip.
Turn counterclockwise to lift the stylus tip.
