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.
