notes: label: Description (Brief)
content: A 5-pin plastic base, banana pins, with tipless T-shaped envelope. Label printed: “Stabilovolt / [STV logo] / STV280/40”. Donor’s card reads: “Voltage stabilizer made by the General Electric Co. Ltd. of England. This tube came from the British battleship Nelson during her visit to the Philadelphia Navy Yard in World War II. Constructed to operate on the gaseous principle, without filament or heater, this tube has a series of four gaps connected across the supply line. Connections can be made from each of these elements through resistors to the line, in effect making several regulating connections in parallel to give one regulated voltage. Also the tube can be connected and used as a voltage divider with different voltages taken from the different gap sections through the necessary resistors and condensers. A very rugged tube capable of handling 60 milliamperes when used as a voltage divider.”
