notes: label: Description (Brief)
content: Western Electric type VT-1 radio tube, nickel-plated brass base with 4 pins, tipped T-shaped envelope. Maker's stamp on base shell. Donor card reads: "Triode made by Western Electric Company, this was the general purpose tube used by all US armed forces for receiving purposes in World War 1. Because of the large elements, is was not a satisfactory radio frequency amplifier, but it was an excellent detector and audio amplifier. Non-corrosive gold alloy tips were placed on the pins for better socket contact. Derived almost directly from the Western Electric 203-A tube, with very little modification of the elements. Variable "B" [battery] voltage was not required for efficient detector action. Filament: oxide coated, 5 volts at 1.1 amperes. Known as the WE type "J" and US Navy number CW-931. Plate impedance 10000 to 25000 ohms; plate voltage 20 to 100; plate current .5 to 2.0 milliamperes."
