RCA, the Radio
Corporation of America was not merely a manufacturer of radio, television, and phonograph
equipment for home entertainment. The company also made vacuum tubes for all sots
of electronic equipment, and produced a weekly radio broadcast called "Magic
Key" on the NBC Blue Network. Sticking to their communications roots, RCA
today markets televisions, microwave ovens, Android-based tablet computers, DVD
/ Blu Ray drives, telephones, 2-way radios, radios, clocks, antennas, and many other
devices - with no tubes in sight, not even in their TV displays.
RCA Radio Tubes Ad
The Quality of RCA Radio Tubes Is Never
Questioned
"Quality," says Webster's Dictionary, "is the excellence of character."
Since the beginning of radio, RCA has spent millions of dollars on engineering
research in the fields of the electronic art to create and preserve "the excellence
of character" that has been built into the hundreds of products that bear the RCA
trademark.
And so it is with RCA Radio Tubes.
The quality of RCA Radio Tubes has been accepted as standard the world over-
... that's why more than 325 million RCA Radio Tubes have been purchased by radio
owners.
... that's why more than thirty radio manufacturers use RCA Radio Tubes as original
equipment.
... that's why the majority of broadcasting stations in the United States, as
well as leading Foreign Stations, use RCA Radio Tubes.
... that's why over 5,000 motion picture theatres use RCA Radio Tubes in their
RCA Photophone Sound Equipment.
... that's why RCA Radio Tubes are standard equipment in Police, Aviation, Marine
and other communication apparatus.
In order to capitalize upon the tremendous public acceptance for RCA Radio Tubes,
radio dealers and service men should keep an adequate stock on hand at all times.

RCA presents the "Magic Key" every Sunday, 2 to 3 P.M., E.S.T., on the NBC Blue
Network.
