1970s Advent Videobeam TV for free near me

The RCA and Philco systems were high end home consoles and we're mostly in the homes of the rich... someone posted a picture of an RCA set in a 40s house here in the last year. Most of the sets had the screen built into the cabinet and looked like a normal 18-24" TV only with an abnormally flat square corned screen for the time. Norelcos protelgram system was the only one to be commonly used with a screen separate from the cabinet...it was probably most commonly sold as an add on in the form of an end table that you wired into the yoke and video circuits of a 10-16" RCA 630 chassis TV or a similar table model set and would project a 3'x4' image on a standard film projection screen (common in homes back then) or a wall painted in a light color.

Protelgrams are a bit more common than the American sets, and there seem to be more Philco 2500s around than most RCAs.

The ETF has pictures of a lot of these sets. Most were rear projection screen in cabinet sets and had sub 21" screens so once brighter 21" CRTs became cheaper they conquered the market fast and only the systems talked for much bigger projection screens held market share.
