CV172

Information - Help 
ID = 28012
       
 
   
Tube type:  Noise Diode 
Identical to CV172 = E1468

Base Loctal-9-Pin (B9G)
Was used by Technology / Measurement
Filament Vf 6 Volts / If 1 Ampere / Direct
Description

Tungsten filament saturated diode, designed to be used as RF noise generator.

18mA mean anode current at 6V.

7V max filament voltage, resulting in a reduced life in the order of 100 hours.

During WWII this tube was appreciated as one of the best noise source. The schematic diagram of a noise generator using CV172 is even given in the volume 'Microwave Receivers' from the MIT Radiation Laboratory series.
