This hooded sweatshirt proudly shows off the glorious RCA brand logo as it was printed on the boxes of the legendary Radiotron vacuum tubes between the 1920s and 1930s.
Radiotron tubes were used over a period spanning decades in many electronic devices such as radios, tv sets, computers and also theremins.
Even the great inventor Léon Theremin used several Radiotron tubes in the design of the famous RCA Victor Theremin and the custom theremin made for Clara Rockmore known as the “Claramin”.
