This voltage stabiliser has a maximum current output of 75 mA. This is above the normal range and was therefore designed to supply a stabilised voltage directly rather than act as a reference in a stabiliser power supply with a series pass valve.

The striking voltage was 135 volts. Pin 4 is a priming anode to strike the discharge.

Looking down into the valve the pinch is on the left, then the bottom mica and then the sealed anode cylinder that has been ribbed for greater regidity. Note that in this balloon envelope there is no locating top mica.

See also CV45 for a later tropicalised version with a classic envelope.

The balloon envelope is 50 mm in diameter, and excluding the B4 base pins is 102 mm tall.
