[sdiy] uPC41C

[Louis van Dompselaar]

I'm repairing an SH3A which has been mistreated a bit by some electronics
novice (to put it mildly).  A number of 2SC945s was removed and replaced
by a random collection of BC547, BC550 and BC560 (yes, in some places
PNP instead of NPN).

More importantly, the uPC41C dual PNP pair was removed and replaced by
two (probably unmatched) BC560's.  As the uPC41C is probably unobtainium,
has anyone ever replaced one with another PNP pair?  The SSM2220 would
be the most obvious choice as it's pin-compatible and easy to obtain.

I do have plenty of 2SA798s lying around as well that can probably be
made to fit the footprint.
