The 2N2920 would work as the input pair in a discrete op-amp, although the noise figure doesn't look brilliant.
It has a relatively high collector-emitter voltage of 60V so would also work as the input pair in a power amplifier.
As @Gus mentioned you could use the LH0002 to buffer an op-amp output. The specs are right for a high-output headphone amplifier. With a good modern op-amp this could be very high performance.
You might be able to find some old application notes for the LH002 like this https://www.ti.com/lit/an/snoa725a/snoa725a.pdf

I am not a fan of designing stuff just to use up old parts. I recall more than once at Peavey when trying to use up old parts actually generated more scrap.
The BUF634 and (more recent) LME49600 buffers do the same basic job as the LH0002 and are popular for audio amplifiers. There's a BUF634 app-note here: https://www.ti.com/lit/an/sboa065/sboa065.pdf which shows the basic hook-up with an op-amp, as well as many designs floating about on other (inferior, naturally) internet audio forums.
