The CV284 is a voltage stabiliser producing an output voltage of 75 Volts.

The data-sheet describes pin 4 as either connected to the anode or to a priming anode. The latter is provided when the circuit design involves connection the CV284 to a permanent heavy load shunting the stabiliser. In any case pin 4 should be connected to the other anode pins via a 15 kΩ resistor.

The cylindrical anode is closed at both ends by the support micas.

The thin glass tube envelope is 18 mm in diameter, and excluding the B7G base pins is 46 mm tall.

Reference: Data-sheet. Type CV284 was first introduced in 1954. See also 1954 adverts.
