Hi Gary,

I dont see anything wrong with Mike's proposal as long as they are the same ratings and used in pairs. If not, he could always use neutral for the return and drive one off one side of 220 and the other off of the other side of 220. The latter would work for an odd number of NST's. In any case, he will need to phase the NSTs correctly before paralleling the secondaries.

This is not a good plan.

Do this experement with two 120 volt light bulbs before you try it with neons. Connect a 100 watt light bulb in series with a 75 watt light bulb and connect them to 220 volts. Watch what happens then decide for youself.

I've had thoughts of running my sg tesla coil from 220v.
I may end up with 2, 3, or 4 NST's.
  If I have 2 NST's, I thought I would series the primaries
and parrallel the secondaries, and run it on 220v. Ok, I think.

If I have 4 NST's, I'll series 2 sets and then parrallel the sets.
Ok I think.

With 3 I don't know.

  Feedback appreciated.
