• 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
Note:
When indicating parts by reference
number, please include the board
name.
