Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270°C during
repairing.
•Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
•Be careful not to apply force on the conductor when soldering or
unsoldering.
Notes on chip component replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

SECTION 1
SERVICING NOTES
This set detects the rotation of the idler gear (A) (side S) using the
photo reflector (PH751). The PH751 is mounted on the MAIN
board, therefore the idler gear (A) (side S) cannot be detected with
the MAIN board removed. As a result, the motor (M601) cannot
be controlled, causing malfunction.
Further, the MD CONT switch (S601) is also mounted on the
MAIN board, and with the board removed, the mechanism posi-
tion cannot be detected and the operation is not changed over.
Therefore, when the voltage check is executed with the MAIN
board removed, follow the procedure provided below.
1. Setting
1) Refer to “3. DISASSEMBLY”, and remove the MAIN board.
2) Connect the MAIN board to the motor (M601) using jumper
wires. These can be connected easily with the use of the
extension tool (Part No. 1-769-143-11) (ten in one set).
3) Connect the AF oscillator to the TP752 and the BT401 (BATT–
).
4) Supply 1.5 V to the battery terminals using the regulated power
supply.
2. Preset state
To set the PLAY, FF, REW modes, the preset state must be set.
1) Check that the slider (NRA) and the MD CONT switch (S601)
are set to the center position. If not, set the preset state as fol-
low.
2) Move the MD CONT switch (S601) to the side, which the
slider (NRA) is facing.
3) The slider (NRA) will move when the regulated power supply
switch is set to OFF once and then set to ON. Move the MD
CONT switch (S601) according to this timing and set to the
center position.
3. FF, REW modes
1) Check that the preset state is set.
2) Input the square wave or sine wave to the TP752 and the BT401
(BATT–).
3) Press the [FF] button or [REW] button .
4. PLAY mode
1) Check that the preset state is set.
2) Input the square wave to the TP752 and the BT401 (BATT–).
3) Press the Ybutton will move the slider (NRA) once towards
the side REV and then to the side FWD. Move the MD CONT
switch (S601) according to this timing will set the PLAY mode
(side FWD). Press the Ybutton another time for a second
and move the MD CONT switch (S601) according to the move-
ment of the slider (NRA) will set the PLAY mode (side REV).
Note 1: If the above fails, perform from preset again.
Note 2: When using headphones, the timing for move the MD
CONT switch (S601) can be determined from the beep
sound.

Tape Speed Adjustment
Procedure :
1. Playback WS-48A (tape center part) in the FWD state and ad-
just RV601 so that the frequency counter reading becomes
3,000Hz.
Standard value : 2,910–3,090Hz
2. Playback WS-48A (tape center part) in the REV state.
Check that frequency counter reading is within ±1.5%
(apporox.45Hz) of the reading of step 1.
Adjustment Location :
4-1. MECHANICAL ADJUSTMENTS
PRECAUTION
1. Clean the following parts with a denatured-alcohol-moistened
swab :
playback head pinch roller
capstan rubber belt
2. Demagnetize the playback head with a head demagnetizer.
Do not use a magnetized screwdriver for the adjustments.
3. These measurement and adjustment should be performed with
the rated power supply voltage (1.5 V) unless otherwise noted.

ELECTRICAL PARTS LIST MAIN
NOTE :
•Due to standardization, replacements in the
parts list may be different from the parts
specified in the diagrams or the components
used on the set.
•-XX, -X mean standardized parts, so they
may have some difference from the original
one.
•RESISTORS
All resistors are in ohms
METAL : Metal-film resistor
METAL OXIDE :Metal oxide-film resistor
F : nonflammable
•Items marked “ * ”are not stocked since they
are seldom required for routine service. Some
delay should be anticipated when ordering
these items.
•SEMICONDUCTORS
In each case, u : µ, for example :
uA.... : µA.... , uPA.... : µPA....
uPB.... : µPB.... , uPC.... : µPC....
uPD.... : µPD....
•CAPACITORS
uF : µF
•COILS
uH : µH
When indicating parts by reference num-
ber, please include the board.
