NOTE:

• Due to standardization, replacements in the

parts list may be different from the parts speci-
fied 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 order-
ing these items.
