Default Re: Decca Bradford Preset Brightness Modification?

The original 10 chassis had a double pole thermal cuttout on the back protecting the mains input and the LT supply. Decca returned to the thermal cuttout on the later and final 31 and 37 chassis with a single pole cuttout protecting the Mains input.
