Zenith Trans-Oceanic Portable Radio- workingModel G500 Chassis 5G40
This radio comes with delightful extras: the original operating guide, schematics page with diagrams and parts list, and a 1950 White\'s Radio Log.I tested it and was able to pick up several stations. The radio gets signal, the sound works, volume dial works. The radio didn\'t come with headphones or the Wavemagnet,although the suction cups are there.The 2 knobs are missing, and everything is a bit dusty.
I will pack it well but can\'t guarantee that the radio will arrive working if it is jolted in shipping.Local pickup is available in the Dayton, Ohio area.
Description taken from antiqueradio.org:One of the more interesting Zenith TransOceanic radios, the G500 provides a bridge between 1940s and 1950s designs. It was manufactured for only 18 months, from 1949-1951, and it originally sold for $99.50.On the outside, the G500 looks nearly identical to earlier 8G005models from the 1940s. It has the same big rotary dial inside a brass bezel, surrounded by a shiny black faceplate.Inside the lid, however, you\'ll notice an obvious difference. The G500 has a large, handsome Zenith badge, proclaiming it as \"The Royalty of Radios,\" where the 8G005 sets had a simple black circle.The big difference between the G500 and earlier models was to be found under the hood.

The earliest TransOceanics used loktal type tubes, which have a glass envelope and a metal base that snaps firmly into its socket. That sort of tube was a good choice in the 1940s, especially for portable and military radios which would endure a certain amount of jiggling.

By 1949, however, the better choice was the all-glass miniature tube, which was cheaper to manufacture, and, thanks to its lighter weight, needing no snap-in base.

The G500 replaced the former 117Z6 rectifier tube with a solid-state selenium rectifier and it substituted a single 3V4 multi-function tube for the multiple tubes previously used for audio amplification.The net result of these changes was to reduce the tube count from eight tubes to five, decreasing the manufacturing cost as well as the the power requirements, which extended the radio\'s battery life.
