(1946 - 7 inch)
This is one of the first post-war TVs, circa 1945 or 1946. The primitive cabinet and chassis circuit design, and the 6-channel tuner, show the rudimentary nature of this very unusual TV. Very few Viewtone television sets were made, and only a couple have ever turned up.
Viewtone advertised its TVs to dealers in the September 1945 Radio-Television Journal. The cabinet measures 19" wide by 22" tall, and 21" deep. The special molded plastic screen has a 6" diagonal. This set has a "pre-war TV" styled chassis, with a large AC transformer--not the typical electrostatic RF system in most post-war 7" TVs. The picture tube is a DuMont 7EP4. The chassis has a combination of Loctal and Octal vacuum tubes. Here is a schematic diagram of a model VP-155, which appears to be almost identical to this set.
A similar Viewtone set advertised in the October, 1945 issue of Radio and Television Retailing magagine
