My guess is that it likely contains one of those tiny Stancor (or equiv) power transformers. Barely the size of a 2W SE audio output unit, they provided 125-0-125VAC @ 10mA and 6.3VAC @ 600mA from a 115VAC primary. A single selenium rectifier and filter cap under the chassis would provide half-wave rectified +300V or about 160VDC with a pair of rectifiers in a full-wave circuit.
