RCA 621TS vs BELMONT 21A21

[benman94]

decojoe is correct, Viewtone produced sets before the 621TS. I have one, with a sales receipt dated November of 1945. That has to be among the earliest postwar sets. Part of the reason the set was able to make it to market so fast is that it is, for all intents and purposes, a pre-war design: AM sound, the IF strip is pulled almost verbatim from an RCA TT-5, the primitive 7EP4 CRT. In fact, if it weren't for the 7EP4 and the 6C4 oscillator in the tuner, it would be rather hard to distinguish it from a pre-war set.
I'd imagine the Belmont was next to market, or perhaps a DuMont offering. In any case, the 621TS and 630TS, which were introduced simultaneously, were not the first postwar sets, not by a long shot.
