ber, please include the board name.
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 ser-
vice.
Some delay should be anticipated when
ordering these items.
• SEMICONDUCTORS
In each case, u: μ, for example:
