replacement for 2sb649/2sd669

[millwood]

I need a set of npn/pnp driver transistors in a 55-60 vdc applications (so the tip31/32 twin is out). originally the schematics used 2sb649/2sd669 but digikey doesn't have them so I am looking for alternatives here.

The transistors will be driving 3-4 mosfets, BTW.

Any suggestions? Thanks in advance.

the 2sb649/2sd669 driving output mosfets sounds like a randy slone amp. he seems to use them in many of his books; nice fellow.
