• 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.

• RESISTORS

All resistors are in ohms
METAL: Metal-film resistor
METAL OXIDE: Metal Oxide-film resistor
F : nonflammable
