They probably did.
You could look up my Telefunken restoration 2 years or so ago. (has both the sch with tubes and my mod for 120V).
They still have a bucking resistor, but when converted to 120V, there was not enough voltage left for the rectifier (50V required) so I used solid state doubler.
The summary voltage of the restr of the tubes is 100V; with the rectifier it would be 150V, so you still had to buck 70V.
But for conversion to 120V it is not enough.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
