content: A small metal and ceramic can with 2 contacts on bottom, one on top. Stamped: “6BY4”. Donor’s card reads: “Triode made by the General Electric Company about 1957. A ceramic high Mu triode of parallel plane construction for use as a grounded grid radio frequency amplifier in combined VHF/UHF television receivers. So used, at 900 megacycles this tube exhibits a power gain of 15 dB and a noise factor of 8.5 with a 10 megacycle bandwidth. Special features of the tube include excellent isolation between input and output, low lead inductances, low interelectrode capacitances, short transit time, extremely high ratio of transconductance to plate current, and small size. Plate is connected to top cap, grid to the upper ring, cathode to bottom ring, and heater to the two bottom buttons. Heater type 6.3 volts at .25 ampere. As a grounded grid amplifier at 900 megacycles, 200 volts on the plate, 200 ohm cathode bias resistor, 5 milliamp plate current.” See also: https://www.radiomuseum.org/tubes/tube_6by4.html.
