Hi John,
 Very nice coil you have. Your careful construction really looks great. The
secondary I was using is no where
near your's in size, but that was just a test.
 How come nobody seems to use tappable primary's and grid coils(within
limits I mean)? Seems alot easier than
changing caps.
 I will use the original mica cap for current limiting. I don't know what I
was thinking anyway, since MOT's
put out around 2300 volts. Mabey I could remove windings from the secondary.
  Regards,
 James T
