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, -X mean standardized parts, so they
may have some difference from the original
one.

•

Items marked “*” are not stocked since they
are seldom required for routine service.
Some delay should be anticipated when
ordering these items.

•

CAPACITORS:
uF: µF

•

RESISTORS
All resistors are in ohms.
METAL: metal-film resistor
METAL OXIDE: Metal Oxide-film resistor
F: nonflammable

•

COILS
uH: µH

The components identified by mark

dotted line with mark

are critical for safety.

Replace only with part number specified.

•

SEMICONDUCTORS
In each case, u: µ, for example:
uA...: µA... , uPA... , µPA... ,
uPB... , µPB... , uPC... , µPC... ,
uPD..., µPD...

When indicating parts by reference number,
please include the board name.
