TABLE OF CONTENTS
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.
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.

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
demagnetizer. (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
supply voltage unless otherwise noted.

ELECTRICAL PARTS LIST
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.
•Abbreviation
EE : East European model
1E : No indication of contry of origin
