ELECTRICAL PARTS LIST

MAIN

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 :

, for example :

uA.... :
