I'm back. Ill start thinking about ballasting when the house's wiring starts burning up.
Anyway, the real point of this thread was to try to find out the calculations of the primary coil- How do I go abouts this??
If I can't find any calculations Ill use vasil's specs and schematic, the only problem with that is I have wound the secondary of 1500 tuns around a 2" former, so I may have to alter it a bit...
i have found you build a good coil if you leave yourself "room to move" as long as you primary has enough room to tune you can get a good output.. i used wintesla at 2/3rds of the rated output of the MOTs (and don't trust your amp meter on the primary side i have had some very misleading results)

Right now I am having trouble sourcing suitable tank caps for cheap, but ill see what turns up.
So the primary is somewhat a guess but I do need some guidelines. I assume the primary is not going to be more than 100 turns but experimenting with 0 to 100 turns, adding one more turn each time could be a very tedious task... Any ways around this?

Lp*Cp = Ls*Cs Starting from the basic equation calculate the secondary resonance frequency. Calculate the inductance of a primary coil with 10-14 turns, according with your secondary parameters (coupling, pri-sec spacing, etc) and then find the primary cap needed.

Yay! Thats what I was looking for (I think) Now all I need is some caps... Thanks,
