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:

, for example:

uA. .

A. .

uPA. . :

PA. .

uPB. . :

PB. .

uPC. . :

PC. .

uPD. . :

PD. .

• CAPACITORS

uF:

• COILS

uH:

The components identified by
mark

or dotted line with mark

are critical for safety.

Replace only with part number
specified.

When indicating parts by reference
number, please include the board.
