In this video we'll explore the early history of vacuum tubes through the pages of a RARE 1933 RCA Cunningham Radiotron RC-11 Manual. We'll briefly touch upon the battle of the tube makers, Lee De Forest's Audion and Elmer T. Cunningham's Audiotron, that took place from 1915-1919. (The Beta vs. VHS of its day!) And we'll talk about the emergence of RCA and it's virtual monopoly on tube distribution through the 1920s. Other players in this saga included AT&T, General Electric (GE), Westinghouse, and Western Electric. here's a cool PDF of the Cunningham Tube Manual from 1932, just before the RCA merger: https://ia801606.us.archive.org/30/items/Cunningham/Cunningham.pdf
