COMMON PARTS LISTS
FOR RESISTORS & CAPACITORS

FOR nesmons
CAPAClTORS -

On this parts list. ten sorts of resistors, & seventeen sorts of
capacitors, which are commonly used in the Sansui products,
are listed. Since these resmtors & capacitors on this list are omit-
ted from service manual, please confirm shape. resistance or

capacnance value, schematic diagram, and this list on the parts
when replacing the parts with trouble. in addition, please pay
attention to fill out the name and stock number (8 digit) of parts
when order.

With the issue of this pans list, please abandon the Common

Part List for Resistance 8i Capacitors" previously issued.

Notice:
Capacitors 8i Resistors on this parts list include one not to
be used in Sensui products. therefore they can not be sup-
plied although ordered.
