Steve Tubejunke 09-05-2007, 12:58 AM Man what a screen size! I don't think I've ever seen a vintage projection set with an almost modern looking screen that is that big. I tend not to have interest in projection sets so I am ignorant to a lot of their charicteristics. How big is that screen. Just a guess I would think 24" or better....... kx250rider 09-05-2007, 11:22 AM I've never seen this wood version with the pop-up... I've had & seen 4 or 5 of the 7'-tall leatherette box style UST Window to the World sets. Charles ChuckA 09-05-2007, 01:25 PM I have some additional info on this set on my web site: http://www.myvintagetv.com/united_states_television.htm It is a huge set, but picture quality is fair. Chuck Phil Nelson 09-05-2007, 10:02 PM I have some additional info on this set 30KV on the tube -- zounds! Phil Nelson ChuckA 09-05-2007, 11:44 PM 30KV on the tube -- zounds! Phil Nelson And even that doesn't help the brightness on this set. Chuck cbenham 09-09-2007, 05:30 PM This set is dimmer because it uses an f 1.9 lens instead of a reflecting mirror. There are pictures and a description of the CRT and lens assembly in Chapter 11, 'Projection Receiver Systems' on pages 226 and 227 of the 1953 McGraw-Hill book 'Principles of Television Servicing' by Rabinoff and Wolbrecht. I wonder how bright the picture would be if a 5AZP4 or a 4820A CRT were installed? ChuckA 09-10-2007, 07:00 PM I wonder how bright the picture would be if a 5AZP4 or a 4820A CRT were installed?
