The VR22 battery triode was a popular type and had many equivalent types. The service types show that it was used by all armed services from the 1930s. As an audio output valve it produced 0.18 Watts.

Power was a wet accumulator for the filament and a dry battery for the anode supply.

The balloon envelope is 38 mm in diameter and, excluding the B4 base pins, is 80 mm tall.
