1964 Color CRT producers and sizes.
Here is something from 1964. https://worldradiohistory.com/Archiv...an-1964-11.pdf ….. page 50 of the 11/1964 Electronic Technician. …………
RCA and Rauland (Zenith) are shipping the new 25” tubes. There are currently 4 US manufacturers of color tubes. (I thought there were more). RCA, Sylvania, Rauland and National Video. Philco and Admiral plan to start production of 21” tubes in 1965. RCA, Rauland and Sylvania will have sample 19” tubes available in 1965. Earlier in the year, Motorola had stated they were having problems securing round and 23’ rectangular tubes from National Video. (Sorry, but I thought I put the link in my prior post. In the next few days, I will have a post with color tv history for the 1950’s, after going thru almost 120 issues of Electronic Technician)
