I think your MMC of .0078 would be just fine to a 30mA NST.  The .03 Maxwell would be too large for your transformer.

Hello all 

new to the list an finally acting on the bug that bit me 30 years ago, building a coil.
So far I'm in the gathering the components stage . have the following :

15kv 30ma neon sign transformer
  components for a RQ type spark gap 
  100ft of 1/2 inch copper tubing 
   50 ft superflex GTO-15 hv wire
   
  Next on the list is the capacitor.. using the various calculators out there I figure I need about .007uf ?  resonant for the transformer would be .0053 but from what I have read using a static spark gap you need a bit more .. is this enough? I am planning on a MMC using Cornell-Dubillier 942C20P15K-F one string of 19 for .0078uf and 38kv  or.. should I go for a Maxwell at .03uf and 35kv? <this capacitor thing is making my head hurt > 

after that it wont be too much worry to get a secondary wound  I have access to a coil winding machine  I haven't figured out the specs on that yet  when I get that figured I can figure out the primary .

I also have 1 833a transmitting tube I picked up somewhere but figure I better start with a spark gap coil before I try my hand at a tube coil 

So my fine fellows.. does it sound like I'm on the right track or have I gone horribly astray? any comments  and or advise would be greatly appreciated .
