EXPLODED VIEWS
NOTE:
• -XX, -X mean standardized parts, so they may
have some differences from the original one.
• 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 number
in the exploded views are not supplied.
• Hardware (# mark) list and accessories and
packing materials are given in the last of this
parts list.

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.
• Items marked “*” are not stocked since they
are seldom required for routine service. Some
delay should be anticipated when ordering these
items.
• CAPACITORS:
uF: µF
• RESISTORS
All resistors are in ohms.
METAL: metal-film resistor
METAL OXIDE: Metal Oxide-film resistor
