Here is one that allows both PI and PI-EL design.  It also includes
analysis (most unusual and most helpful, I think you will agree),  to
show you what you are getting with a given design.  Transmission
is shown, with tabulated data for fundamental, second, and third
harmonics.  Voltages across each component and current through
each component are shown.  Boxes to enter values and buttons
to "tune" critical items.
