A TU77 can run on household 240v. If I recall it used the 240 for the 
big blower motor and the rest of the stuff ran on 110.

1 phase 240 is just 2 120 volts out of phase. Looking at the 780 it has 
3-5 power supplies in it, each one running on 120v. My guess is the main 
fan blower is 3 phase 208, and each of the power supplies is run off a 
208-common leg (giving 120v).

Big ole monster, but if you can put a 240v motor on the blower you 
should be able to rewire it to run on a couple of household 240 circuits.
