ELECTRICAL PARTS LIST
NOTE:
• Due to standardization, replacements in the
parts list may be different from the parts
specifiedin thediagrams orthe 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
• 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.
