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

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