And there were 'farm' sets that worked off of 32 volts, some had vibrator
power supplies but some used 32 VDC as the B+. The 32 volt systems used
outlets just like 110vac outlets.

Could well have been 32V --- just assumed 6V based on the batteries Dad had in
the cellar. They were wired direct to the radio, not through any outlets.
Radio was the only "electric" thing in the house.
