Besides, that DC from ConEd probably isn't that pure. It's likely to just be rectified AC. Maybe from a 3 phase AC supply, so the low points don't hit zero. (the next positive phase waveform takes over before the first phase's zero crossing). Full of ripple. |

Come to think of it, I also looked at a 30s Zenith tombstone radio for a guy that was 32v. It was otherwise the same radio as the "Waltons" set that I suppose is one of the prized Zeniths.
I wonder if there were 32v Stratospheres??? Charles |

32v was pretty popular across rural America back in the thirties. I often hear of "Delco light plants" that were just 32v generators. After rural electrification there could not have been very many folks who stayed with the old setups.
I think with the AC/DC sets DC wasn't so much part of the planned design as it was just an added benefit. The vast majority of buyers had AC. I bet if you piled up all the tube radios ever built, 80% of them would be All-American Fivers. That cheap chassis allowed everyone to have a radio, and almost everyone to have several radios. It may not have been a safe design back in the thirties but things were different back then-lots of cars were still in service with crank starters, electric fans had holes in the guards big enough to stick your foot in-by the fifties these were built a lot safer.
