RCA Electronics Course
I remember watching on TV in the mid 1960's a wonderful basic electronics course taught by John W. Wentworth of RCA. It covered basic components and circuitry, all the way up through audio, radio and finally even television.
This series was comprised of a dozen or so half-hour lectures, wonderfully illustrated with professional graphics, chalkboard drawings, and in many cases actual demonstrations. The last show/lecture in the series included a study of how black & white television worked, not just including receivers, but also cameras and video recording. They opened up some of the broadcast television equipment of that era to explain how it worked, including a quadruplex "Television Tape" recorder. (I think it might have been an RCA TRT-1A.) In my area, it was broadcast from FILM on educational television WQED-TV. However, they probably got it from NET (PBS predecessor) or perhaps even directly from RCA. The course appeared to be targeted to a national audience, or perhaps even the military or other very large entity. It was not a locally produced show. I'm wondering if this series might have been produced to go along with printed RCA training courses. Perhaps NET somehow got access to these films after they were produced and decided to air them on TV. Does anyone else remember seeing, or even hearing about, this excellent series of filmed lectures on electronics? Do you remember the title? Does anyone know where these films might be today? It would be great if a set of these films could be found, especially that last episode, because it really showcased, in great detail, the television technology of that era.

Wild guess - RCA proprietary, released to NET or even just to that station after someone begged and pleaded for free material to fill their schedule.
I would love to see what sort of lecture Wentworth could produce - have only read his publications.
