Could just throw a 110V heater under it, but the problem is that the 10 is an original 220V version, and would like to keep it that way.
First original 1970s 220V #10 i´ve seen, and furthermore most likely born as a demonstrator/salesmans example for the European market back then.
Does it have a 220V tag, or just the usual Jensen way of crossing out and re-marking?
