Dave is correct on the Philco model 32. It was made in different cabinets for several years until about 1935. These used vibrator supplies for high voltage. Philco made a model for the 1936 model line, their last 32 volt set model 642 which like some of the other sets made used low voltage, 32 volts for B+ with type 48 tubes in push pull. I have a Lafayette 32 volt set like the Philco 642 with type 48's. The power output is only about a third of a watt but the set performs amazingly well with only 32 volts on the plates of the tubes.
