Thank you very much Ted. I am looking into building a new coil very shortly ( I have quite a collection now ) as soon as I finish the new secondary I will consider using a DC resonant charging system for the primary circuit in my new coil. Thanks for the links!

While 2kV or so in a classic AC spark gap design is so low that gaps are tricky my view is that the appropriate configuration to use with a single MOT is DC resonant charging. There are many successful single MOT DC designs similar to that of Steve Connor (Scopeboy) at http://scopeboy.com/tesla/tc2schem.html
