True, the 750 might need 220. I really can't remember. But when I set u= p
a few, with a TU78, and a few RM05's at the warehouse I was storing them, I really only needed a single phase.

And again, in the US, 220 requires "two phases" but the actual eq= uipment
only needed a single source of 220. So it was "single phase". Cle= ar as
mud? :)

A quick trawl through the Bitsavers = 11/750 field maintenance docs did not definitively answer the question.=C2= =A0 Looks like it could have been 240V 12A or 120V 24A.
