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
In each case, u : µ, for example :
uA.... : µA.... , uPA.... : µPA....
uPB.... : µPB.... , uPC.... : µPC....
uPD.... : µPD....
• CAPACITORS
uF : µF
• COILS
uH : µH
