Seventy-five years ago today, the October 3, 1946, issue of the Pittsburgh Press carried this ad for the Emerson model 523, which tuned the broadcast band and would run off batteries or household current, with automatic switchover.

The set retailed for $47.20, which, according to this inflation calculator, works out to $662 in 2021 dollars, so the set was something that would be purchased by the well heeled.

The ad noted that other models started for $21.60, and also featured the model 512 radio and model 506 radio-phono.
