content: A 7-pin glass base with tipped T-shaped envelope. Miniature tube. Stamped: “3A5 / CBS / Made in U.S.A.” Donor’s card reads: “Twin triode made by CBS-Hytron for use in high frequency applications. The relatively large filament employed enables it to supply the high peak currents required on radio frequency power applications. In Class C service with its units in push-pull this tube will deliver a power output of 2 watts at 490 megacycles. The two coated filaments may be operated in parallel at 1.4 volts or in series at 2.8 volts and .22 or .11 ampere, respectively.” See also: https://www.radiomuseum.org/tubes/tube_3a5.html.
