TABLE OF CONTENTS
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.

PRECAUTION
1. Clean the following parts with a denatured-alcohol-moistened
swab :
record/playback/erase head pinch roller
rubber belts capstan
2. Demagnetize the record/playback/erase head with a head de-
magnetizer. (Do not bring the head demagnetizer close to the
erase head.)
3. Do not use a magnetized screwdriver for the adjustments.
4. The adjustments should be performed with the rated power sup-
ply voltage unless otherwise noted.

Procedure:
• Reform 2.4 cm/s speed adjustment before 1.2 cm/s speed adjust-
ment mode : playback
Frequency difference between the beginning and the end of the
tapeshould be within ±0.5%.
Adjustment Location :
First remove the plate, blind.
1. Tape Speed : 2.4 cm/s
Playback WS-24 (tape center part) and adjust RV601 so that
reading on the digital frequency counter becomes 3,000 Hz.
2. Tape Speed : 1.2 cm/s
Playback WS-24 (tape center part) and adjust RV602 so that
reading on the digital frequency counter becomes 3,000 Hz.

ELECTRICAL PARTS LIST
Ref. No. Part No. Description Remark Ref. No. Part No. Description Remark
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 and -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
number, please include the board.
