What's it like---tube, solid state...? Any indication of where it was made? The USA Regal company, based in Chicago, was mainly an instrument maker---the brand was owned by Harmony from sometime in the 1950s, which I assume means any Regal-branded amps would have been made by Valco. But there are also apparently some Regal amps that were made in Canada, and I don't know if that's the same company or not.
If it's a Valco-made tube amp, it ought to be good for *something*, but that something may or may not be bass. I couldn't find anything about the specific model number, but it might be possible to figure out what a similar Harmony or Supro model would be.
Photos would be good too.
Also, a second to what RickenBoogie said. Don't mess around inside tube amps unless you know what you're doing---there are voltages in there that can kill. It isn't *hard* to learn how to do it safely, but it's not a good thing to learn about through trial and error.
