My HP-24 supply is for my HA-14 SSB linear amplifier. Cool little
thing, it's a simplified SB-200 with a separated power supply.
They managed to fit the transformer and caps onto the same chassis as
the HP-23 transceiver supply.

I originally did get it in a speaker case, but, I traded it away for
something else...

If you wanted to keep the speaker and e-bay the power supply, I could surely
understand that. *No one seems to make good station speakers any more.
