Bob.
 
I believe you claim.  That is great performance Bob.  I achieved 8 feet
terminal to terminal in the lab with my original first compact twin prototype
on just 2.5 KVA in, (I have all this on videotape with witnesses) so that
sounds close to your efficiency.  My coils were also wound with #18 enameled on
10" forms.  Rotary gap and Condenser Products 0.05uF capacitor.  I've never
found any nF caps to experiment with, but your experience would indicate that
they can apparently work just as well.
