RCA Electron Tubes
November 1951 Radio & Television News Article

November 1951 Radio & TV News

I like the tag line RCA (Radio Corporation of America) chose for this 1951 advertisement pitching their vacuum tubes: "Electron tube with a military mind." However, what really caught my attention was the illustration that borrows the "ship in a bottle" (see example) theme. A lot of younger people might have no idea what is being alluded to given easy access to cheaply manufactured faux examples. Modern manufacturing techniques makes it relatively simple to form a bottle (especially a plastic one) around a pre-built ship model. The original technique required preparing much of the model as possible ahead of time, and then inserting the individual pieces through the narrow bottle neck and performing assembly using long nosed pliers and/or tweezers. A lot of preparation, patience, and skill is required to make a fine looking model. Maybe the advertisement creators stumbled upon this appropriate analogy to the challenging job it was to supply America's war machine with high performance and reliable tubes, and their intention was merely a juxtaposition of its vacuum tube product line with the myriad kinds of equipment that they helped the Allies ultimately secure victory over Axis powers.

RCA Electron Tubes Advertisement

RCA Electron Tubes, November 1951 Radio & Television News - RF CafeElectron tubes are the nerve ends of military intelligence - in systems set up and maintained by RCA Service Company field engineers.

Electron Tube with a military mind

With the rapid advance of airplanes, tanks, fast ships, and mechanized weapons of war, a swift, sure means of communication and detection is as important as are the new weapons themselves. It is provided - by electron tubes and electronics.

So important is this area of military intelligence that RCA Service field engineers - here and abroad - have lifted their efforts to new peaks. Working with our Armed Forces, they install and maintain such communications systems as short-wave radio and portable radiotelephones. They work with systems of detection, such as radar. They help ships and planes navigate with loran and shoran. These engineers are the link between research developments made at RCA Laboratories - and America's military strength.

The number of RCA field engineers has tripled since World War II. And they serve where needed, wherever an electron tube's "military mind" can be of military use.

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
