A digitally enhanced version of the RCA Television Division" history film. An excellent 1956 color film showing the technology of building a television, including vacuum tube production, quality control and testing of electronic components. Wonderful vintage technology from a great American company. I hope you enjoy this journey through the past. Run time: 26 minutes. (Educational, Historical)
Here are several suggested videos related to RCA Computers, and other early vacuum tube computers.

Footnote: The 1950’s production techniques and testing of TV vacuum tubes had to be improved even further for the tubes used in computers. Computer tubes demanded a higher rating for reliability and longevity, since early computers used thousands of tubes and tube replacement was a laborious task.
