You can also look in the NTE Cross Reference S0024 is equivalent to NTE-199

Talon has the 0024's, but not the 27's.

But, they look like pretty basic and easily subbed transistors. A BC546 would be an easy sub for the S0024, and an MPSA42RA looks OK for the S0027. Both of those are stocked by Mouser.
