The components identified by
mark 0 or dotted line with mark
0 are critical for safety.
Replace only with part number
specified.
• Items marked “*” are not stocked since they
are seldom required for routine service. Some
delay should be anticipated when ordering
these items.
• The mechanical parts with no reference num-
ber in the exploded views are not supplied.
• Hardware (# mark) list is given in the last of
the electrical parts list.
NOTE:
• -XX and -X mean standardized parts, so they
may have some difference from the original
one.

NOTE:
• Due to standardization, replacements in the
parts list may be different from the parts speci-
fied 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 order-
ing these items.
• SEMICONDUCTORS
In each case, u: µ, for example:
uA. . : µA. . uPA. . : µPA. .
uPB. . : µPB. . uPC. . : µPC. .
uPD. . : µPD. .
• CAPACITORS
uF: µF
• COILS

The components identified by
mark 0 or dotted line with mark
0 are critical for safety.
Replace only with part number
specified.
