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.

• 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.

• SEMICONDUCTORS
