Hi all,
If one had a coil powered by a 9/30 NST and all things remaining the
same, added another 9/30 NST how much of a jump inwards on the primary
would they need to make?
I ran this through TeslaCAD and it jumped in from turn 9-10 all the way
in to turns 6-7. This seemed like a bit much to me and I was curious to
see what you all thought. I will be doing just this tomorrow so any/all
ideas or suggestions are welcome. BTW you can see specific coil details
at the link below.
