A 16 inch porthole television, recently restored by me. It is a Zenith H2438, which uses the 24H20 television chassis, and a basic power supply and single-ended audio amplifier chassis, with 24 vacuum tubes in total.

Super! AAAA+++ Images are very surreal! The industry should have kept the port-hole screens!

Would anyone know how I would go about in finding / buying one of these? I love the look of the porthole television. (Im in UK not sure if that has any difference.)

Was the imagery made to fit the 'porthole' screen by vertical-stretching or horizontal-overscanning, or both?
@tom16mm
@tom16mm 7 лет назад
Vertical stretching. Basically, the image raster is stretched vertically (or squashed horizontally) into a square, and the corners of that square are lost to overscan. This set has a switch on the font panel that gives the viewer the ability to reduce the vertical height of the image to undistorted 4:3, leaving bars at the top and bottom. It's an early aspect ratio control!

@@tom16mm I just herd that the rational of the time was that a round screen is a fit for round human eyes.

I have just acquired a 1950 Zenith TV, the audio works fine but there's no picture, any suggestions on where to start to get this fixed? I'd love to have it as a working TV

This. Is. Awesome. Thanks so much for uploading this. *I* want a round TV. Where can I buy one? None on Ebay. Someday all TVs and computer monitors will be round or oval. (I saw it in the "1984" movie. So when we get to the very distant, futuristic year of 1984 all the TVs will be round.) Now round screens didn't last long in the beginning of TV, because people were "squares" back then. But now people are liberated, and need to be freed from all the bothersome corners and right angles.

Yep, you got it! Elmo TRV-16. Mine has lots of issues with the camera, but it works decently with black and white material.

Looks like a rather expensive and pointless hobby. Old clocks, cars, and that sort of thing, at least still have some purpose and functionality. Unlike a seventy year old television that's so obsolete that it bares little resemblance to a modern television, and is for all practical purposes non-functional.
