The PA20 is a PX4 style of triode. Perhaps a wartime old stock replacement.
While some "Audio" people want them there is nothing great about triode PAs. Pentode/Beam-Tetrodes are far better. It may only have been due to royalties that PA triodes were made so long rather than Pentode/Beam-Tetrodes being used universally.
A nice little set to have if it cleans up OK, even just for display.
