content: A 4-pin ceramic base with top and side contacts, T-shaped envelope. Stamped on envelope: “Eimac / Reg. U.S. Pat. Off. / 35-TG / Made in U.S.A.”; on base: "JAN-CIM-35TG / Made in U.S.A." Donor’s card reads: “Triode, transmitting type made by Eitel-McCullough of San Carlos, Calif., from about 1933. A high Mu triode having a plate dissipation of about 50 watts. For use as an amplifier, oscillator, or modulator at frequencies up to 100 megacycles. The same as the type T-35 except that the grid is brought out through the side of the envelope. Thoriated tungsten filament: 5 volts at 4 amperes. Amplification factor 40. When used as a Class C amplifier 1500 volts at 90 milliamps on the plate, 150 volt negative control grid bias, this tube will deliver up to 105 watts of radio frequency power up to 100 megacycles.” See also: https://www.radiomuseum.org/tubes/tube_35tg.html.
