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 earlytomid 1950s. And they appear in this, the cute, strange, delightful Tiny Tooner radio.
