This EHT rectifier is a low power device, suitable for the CRT's used in indicating instruments such as oscilloscopes.

The number of equivalents suggests that this was a standard device of its time.

The series resistance to be used with the valve has to be above 62,000 Ohms and the maximum reservoir capacitor value us 0.25µF.

The anode is a cylindrical bell with the cathode assembly held vertically within it. The heather/cathode is always separated from the anode by a 3.5 mm gap.

The thin glass tube envelope is 17 mm in diameter and, excluding the B7G base pins, is 48 mm tall.
