CV172 noise diode
The prototype for this valve is E1468.
Saturation occurs with an anode voltage not greater than 50V. At a filament voltage of 7V the life of the valve is reduced to 100 hours. The value of the saturated anode current is normally regulated by variation of filament voltage.
Views of the internal structure of the valve. The filament is a single hairpin supported in the centre by a spring. The anode is supported at each side by metal plates which also support the getter carrier at the top of the envelope.
