	These are all Japanese transistor numbers, sometimes
written 2SCnnnn; I have a cross-reference for the first,
which is a NPN audio power transistor (replaceable by RCA SK9085
if you can find an SK-series dealer in your area).  The second
and third numbers aren't in my book (1985 edition) but a dealer
who stocks SK parts can probably find them.  All the Cnnnn parts
are audio frequency NPN bipolar transistors, if that helps.
	Parenthetically, some such components are matched with
diodes on the same heatsink, and replacements for such have
to be exact.  In addition to RCA SK series, Philips ECG series
is a widely stocked consumer equipment semiconductor replacement
line; check your phone book for either, under Electronic Equipment
and Supplies.
