  All -

  Beware of those so called TC simulators that are not supported by real
world empirical data. For example, finding an optimum coupling without real
world data on sparkovers between pri and sec coils will be of little use.
If a recommended coupling of a certain amount causes sparkovers the
coupling information is of no help. 

  A decending curve and an accending curve can be made to intersect a point
on the graph. The product of the two curves will be another curve that
gives an optimum condition where the curves intersect. This scenario is
often used to find a prefered condition. However, it must be understood
that there can be certain limitations. Computer programs like PSpice must
be properly applied to Tesla coil problems if they are to be beneficial to
the designer.

  I agree that a program made especially for Tesla coils is the best
approach. With this type of program the essential elements of both theory
and real world empirical data can be utilized to best advantage. All of the
unnecessary features of a "Universal Circuit" program based only on theory
can be eliminated. This would greatly simplify the use of the TC program
and coilers would be more apt to work with it.
