notes: label: Description (Brief)
content: "A three-element, argon filled, grid-controlled rectifier with a filamentary cathode. It is primarily a rectifier of low internal impedance whose conduction cycle is determined by the relative instantaneous control-electrode and anode potentials. It is intended for use in special circuits as a relay or trigger-action device. A few of its other possible uses are: as a controlled-frequency oscillator giving a square wave-form, as a voltmeter or volume level-indicator, or as a source of sweep-voltage for a linear time axis."
