If you were looking for a radio in Milwaukee a hundred years ago, this Magnavox TRF-5 would have been a good choice. As the name implies, it had five tubes. Apparently, 3 of them were for RF, with the other two for audio amplification to drive the included speaker.
It is shown here in an ad for Gimbels, in the December 5, 1925 issue of the Milwaukee Leader. The price tag of $89 works out to $1651 in 2025 dollars.
