The CV188 voltage stabiliser was designed for accurate regulation. It has a B4 base but the envelope is small and compact. The striking voltage is 140, and once ionisation has occurred the tube can regulate the 100 Volt output to 2 Volts for currents of between 1 and 8 mA. This high stability low current device would be useful for stabilising supplies to oscillators or as a reference voltage in valve voltage stabilisers.
The wide glass tube envelope is 27 mm in diameter and, excluding the B4 base pins, is 63 mm tall.
