This exhibit is a cold cathode voltage stabiliser. VS111 is the RAF designation and AW3 is the UK Army designation. Both types were renamed CV1110.
The working voltage is 120 Volts and for currents of between 6 - 75 mA the voltage is maintained to five volts of the target value.
Such valves would be used to achieve stable voltages for sensitive circuits such as oscillators. Also such a tube run at constant current would form a reference voltage for a valve voltage regulator. Oscilloscopes and radar displays would be fed from fully stabilised supplies.
The discharge is held within the closed cylinder the maintained voltage is a function of the electrode geometery and spacing.
The balloon envelope is 50 mm in diameter and, excluding the B4 base pins, is 106 mm tall.
