This unit was designed to supply domestic radios from 220V DC Mains. The output was two voltages, one lower voltage for detector and earlier valves, and one higher voltage for audio output valves.

The unit has switched potentiometers to supply set voltages.

This case was connected to earth, to prevent accidental contact with the input DC.

The mains input plug was reversible, in case the output polarities were incorrect.
