This “Semiconductor Pin Assignments” CD-ROM allows you to search for

semiconductors used in B&P Company equipment.
Semiconductors that cannot be searched for on this CD-ROM are listed in the

service manual for the corresponding unit. The service manual contains a com-
plete list of all semiconductors and their ID Nos., and thus should be used together

with the CD-ROM.

The following describes the semiconductor types used in
this unit.

For semiconductors marked with page numbers in the
index, refer to the corresponding pages in this section.

However, in some cases incompatible types are also listed,
therefore, when a part is to be replaced, also refer to the

Spare Parts section.
In addition, for semiconductors with ID Nos., refer to the

separate CD-ROM titled “Semiconductor Pin Assignments”
(Sony Part No. 9-968-546-xx) that allows searching for

parts by semiconductor type or ID No.
The semiconductors in the manual or on the CD-ROM are

listed by equivalent types. Thus the external view or the
index mark indication may differ from the actual type.

Pin assignments and block diagrams are based on the IC
manufacturer’s data book.
