The part No. of transistors,
IC and diodes mentioned
in the
schematic diagram stand for production part No. Regarding the
part No. with &Y mark, the production part No. are different from
the replacement part No.
Therefore, when placing an order for
replacement part, please use the part No. in the replacement
part list.
