I've been using a 115V 60Hz (15KV/30ma) Transco NST for months on UK
50Hz mains with no problems.  I'm using a 240 / 115 stepdown

I've also run two 115V 60Hz microwave oven transformers with their
primaries in series directly from 240VAC juice, with no ill effects. 
I don't think you'll have any trouble with your NSTs wired in series 
and run with 50Hz power.

You will need a slightly larger primary capacitance if you are
trying to impedance match your xfmr to your cap.  Also, your coil 
will fire at 100pps instead of 120pps.  I don't think it matters very 
much though.

In a few weeks I'll be making a trip to a country that uses 220v as the
standard line voltage.......I have a large supply of 15kv NST with the
primaries rated at 110v.I plan on bringing some friends a medium size
TC........would I be able to use 2 -15kv NST and run the primaries in series
using the 220v line voltage and of course hooking up the secondaries in series
to the tank circuit of the TC? Any problems here?.........Also their A/C
voltage is 50hz,but I don't think that will matter except a little different
tuning from 60hz? I want to take every thing with me and won't have time to
search for local 220v NST.
 Thanks, Dan
