Rod,

Not intending to be flipant, but ....3,555,555.556 volts!!!!!!

Whew! Golly!

In probably the most highly developed mathematical model imaginable, I think
there might be a bit of bauble about the first digit (3) in your answer,
much less the .556volt trailing figure!!! 

 There are no such useful equations extant that wouldn't pose a great threat
of self-deception to any person so bold as to use them or foolish enough to
accept their resultant output values.

This is a long sought form of teslarian nirvana.  Just plug in the numbers,
turn the ole crank and presto, infinite precision and confidence in output
voltage prior to the first turn of wire on a resonator.

If someone thinks they have it,  walk away,  They haven't built six of these
systems yet.  Most haven't built one!!!!

  Armchair theorists are as common as the seasickness in this business.
Followed quickly by wanna-be mathematicians.

Builders seeking true engineering guidelines are few and often reticent on
precise value predictions in direct proportion to the number of systems they
have assembled.
