GEC CV2171 (A2087) noise diode for frequencies up to 500MHz.
The valve has a tungsten filament and so is a bright emitter.
The specifications of the valve say that saturated emission of 5mA should be obtainable at a maximum anode voltage of 40V. At 20mA saturation, the valve life is reduced to 100-300 hours. The value of saturated anode current varies with filament voltage. The prototype of this valve was VX3120.
