The AC-DC sets built in the US, weren't only built for cost reasons, but there was a lot of DC districts in the larger cities.
Philco built a few, strictly 110 volt DC sets, in the early 30's. They used paper power supply caps, in case it was connected reverse polarity.
BTW, didn't Britain have DC districts in some of the larger cities, as well.
