RCA (Radio Corporation of America)
RCA appears in the archive mainly as a tube maker and publisher. Its receiving tube manuals were the standard reference of the tube era, and the archive has a 1950 edition, RC-16, a 336-page softcover covering tube theory, testing and data for every RCA receiving type of the day.
Many of the tubes that power amplifiers elsewhere in the archive started at RCA. The company introduced the 6L6 beam power tube in 1936, and its engineers in Camden, New Jersey, developed the 12AX7, which went on sale in 1947. RCA-branded tubes are also among the most common originals found in American amplifiers of the 1950s and 1960s.
The field guide to amplifier tubes covers these and other types, and the RCA maker page lists the RCA items on file.
