notes: label: Description (Brief)
content: A plastic base with 8 pins and center post, T-shaped envelope. Donor’s card reads: “Medium Mu twin triode made for the Admiral Corporation prior to 1950 for use in their television receivers. Glass octal type used as a combined vertical oscillator and horizontal deflection amplifier. Also used as phase inverters, multivibrators, or resistance coupled amplifiers in radio equipment. Except for the common heater, the two triodes are independent of each other. This particular tube was purchased in [my] television set on 1 November 1950 and was used daily until 21 December 1957 [when it] was removed ... when the filament emission fell below a satisfactory point. Heater type filament: 6.3 volts at .6 ampere. Plate voltage, each triode, 25 volts; negative control grid bias 8 volts.” See also: https://www.radiomuseum.org/tubes/tube_6sn7gt.html.
