CV172 noise diode
|
The valve measures 70x36mm
overall and has a B9G base |
The prototype for this valve
is E1468.
Normal filament voltage |
6V |
Mean filament current |
1A |
Mean saturated anode current |
18mA |
Max permissible filament
voltage |
7V |
Approx spread of Vf over
a number of valves for Ia (saturated) |
6.25 to 6.75V |
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.
