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.... : µ A.... , uPA.... : µ PA....
uPB.... : µ PB.... , uPC.... : µ PC....
uPD.... : µ PD....
• CAPACITORS
uF : µ F
• COILS
uH : µ H
When indicating parts by reference num-
ber, please include the board.
