1950s TWO-TUBE pocket-size radio RARE 'Tiny Tooner' pre-transistor -

Subminiature vacuum tubes. Developed during the 1940s, these little tubes were quickly supplanted by transistors in electronics devices. But they did appear in a few, rare devices highly prized by collectors for their rarity and their quirky technology. They appeared in this, the Belmont Boulevard radio from 1947. That's a good looker and there is a video on this channel all about it. And those little tubes appeared in this Emerson 747 model as shown in this striking ad for it that ran in the early-to-mid 1950s. And they appear in this, the cute, strange, delightful “Tiny Tooner“ radio.
