Extras ▼

 

The CV3798 is a 75 volt voltage stabiliser tube. The prototypes for this stabiliser were the OA3 and the VR75-30.
The striking voltage is 100 but a supply of 105 volts is suggested to take into account tolerances. The minimum current is 5 mA and in the working range of 5 - 40 mA the voltage regulation is 5 Volts.
The classic envelope is 35 mm in diameter and, excluding the IO base pins, is 84 mm tall.
References: Datasheet, 1040 & 3002. Type CV3798 was first introduced in 1943.
