Scored one on the bay tonight, never really seen any octal AA5 tubes in the ST shape, so had to have it. Zenith branded tube, seller showed it as having tested out good. I know these were used in those Zenith Bakelite chassis radios, but were they as common as a 12SA7GT? (or even a metal SA7)

Yes, have only seen in ~1940 Zeniths. Has anyone ever seen a 35Z5G or 35L6G?

Yes, it plays. No, there was no FM stereo in 1932. Yes, some people still enjoy AM radio.
