The VR105/30 is a voltage stabiliser. The striking voltage is 135 Volts and the regulation is 4.0 Volts for currents between 5 and 40 mA.

The RCA identification is on the black base and the type designation is etched into the glass envelope.

The top view indicates the simple construction of a central wire anode in a circular cathode tube.

The classic envelope is 38 mm in diameter, and excluding the IO base pins is 87 mm tall.
