How to remove the drive circuit P.C.B. and stator
frame
. Remove the main base and cabinet. (Refer to “How to
remove the main base and cabinet’”’.)
2. Remove the drive circuit P.C.B. setscrews @ ~@®.
(See Fig. 5)
3. Remove the stator frame setscrews @ ~ @ .
Remove the regulator transistor (Q3) setscrew @) and
connector @. Then, the drive circuit P.C.B. can be
separated from the stator frame. (See Fig. 5)
4. When removing the drive circuit P.C.B. and stator frame
together, remove the connector @ and setscrews @~
@ . (See Fig. 5)
e How to remove the arm base and tonearm
. Separate the main base from the cabinet. (Refer to
“How to remove the main base and cabinet”’.)
2. Remove the arm base setscrews @) ~ @. Then, the arm
base can be removed. (See Fig. 6)
3. When removing the tonearm, turn over the arm base and
remove the PU fixing plate setscrew @ and canceller
spring. (See Fig. 7)
4. Remove the phono output P.C.B. setscrew @ and un-
solder the 5 lead wires from the tonearm. (See Fig. 7)

5, Remove the tonearm setscrews @ and @ .
Then, the tonearm can be removed in the direction of
the arrow. (See Fig. 7)
6. When removing this lift base plate, remove the arm lift
setscrew @) before tuning over the arm base, and then
remove the arm lift. (See Fig. 6)
Note: Remove the spring under the arm lift at the same
time.
7. Remove the anti-skating control knob. (See Fig. 6)
8. Turn over the arm base and remove the PU fixing plate.
9. Remove the lift base plate setscrews @) and @. Then,
the lift base plate can be removed.
10. Before mounting the arm base, make sure that the auto-
matic mechanism is in the initial stage, and then shift
the cueing lever of the arm base down in the direction
of the arrow in order to make cueing-up. (See Fig. 7)
