NOTES TO SERVICE ENGINEERS
MM Please -contact the nearest Sansui Authorized
Service Station for replacement parts. When order-
ing them, look up the part lists on pages 19 to 26
and let us know (1) the amplifier's model number,
2) name of the printed circuit board, (3) part No.,
(4) name of the part, and (5) its stock No. Using
nonstandard parts for temporary relief often impairs
the sound quality and over-all reliability of the
amplifier. Please take the trouble to contact your
nearest Sansui Authorized Service Station.
Mi Consult pages 17 to 26 when making repairs or
adjustments. To check or measure the amplifier
performance, connect load resistance of 4 to 16 ohms
to the amplifier's speaker output terminals first. To
check the electrical output characteristics, do not
remove the bonnet and bottom plate.
