I have 250v incoming to the main transformer of my mill, the output of the transformer is 65v. I need to get this down to about 60v, I am trying to come up with options.
Probably the easiest would be to buy a 250v to 240v(or somewhere around there) step down transformer, but I don't have the cash to spend.
Could I wrap a few more turns on the primary side of the transformer?
What about putting a 5 ohm, 50 watt resistor inline on the secondary side. The max current is 10 amps, and I know the voltage would vary with load (that's probably a bad idea). I should mention this transformer is for stepper power, not control logic.
Any more thoughts?

Wouldn't adding turns to the primary be equivalent to taking turns off the secondary?
It's actually a 3 phase transformer.

Yes, Of course your right, the turns/volt ratio would increase, you would have to change all three primaries, or use two buck/boost transformers on two of the secondary phases.
