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 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...
