Not sure it was half-wave rectifiers, more like thyristor power supplies chopping great lumps out of the mains. These were used in sets that had 'half-mains' live chassis at around 110V....never did like the idea. The manufactures used big chokes on the mains input to reduce the noise fed back into the mains.
