notes: label: Description (Brief)
content: A 6-pin metal base with center post, top contact, T-shaped envelope. Stamped: “Bendix / Made in U.S.A. / HY-G-300”. Donor’s card reads: “Beam power amplifier made by the Red Bank Division of the Bendix Corporation, Eatontown, NJ. Built for the most severe service, to Mil-Spec for missile and similar service. Nonex hard glass with a heat expansion factor of one-third of soft glass is used for the envelope. This combined with the tungsten stem seals helps to ensure long life. Exhausted to an unusually high degree with an outgassing of all elements by means of electronic bombardment as well as induction heating insured a maximum life expectancy. Capable of continuous operation at temperatures up to 300 C. Pure tungsten heater: 6.3 volts at 1.2 amperes. Ceramic shield prevents getter flash from forming interelectrode leakage. Maximum DC plate voltage 3000, screen voltage 850, plate dissipation 30 watts.” See also: https://www.radiomuseum.org/tubes/tube_6889.html.
