Ctc-1

[Geist]

Hi All;
Is/Was there a CTC-1 or CTC-2 ?? I have seen mentioned a CTC-5, But Don't know the History of the CTC series, nor of What RCA put out as far as Color sets.. I know that their tri-gun color system is what was adopted over the CBS color wheel system.. But, don't know what model was the first RCA color set released by them.. If, I remember right it would have been around 1955 or 1956, Am I right ?? When I was a kid, I had some black and white sets that had plug in for the CBS Color system.. And later saw an article about it in a Popular Electronics article..
THANK YOU Marty
