"PN4250" (40V breakdown) or "PN4250A" (60V breakdown) might
be easier to find than the "2N" version. These are in a
TO-92 package. The "A" version is identical except for the
higher voltage rating. The PN4250A is used in various places
in the 990 discrete op-amp.

Idunno bout the rest of you, but when I'm trying to select parts that I
don't understand well enough to choose good ones over bad, I scrounge
up a schematic for a circuit I know is done right, and see what they
used. The fact that JH uses this part would be a good argument for me
to use it.
