I'm most interested to hear the results of further expts. I like the 
idea of the isolated topload to add C to the driver sec. I suppose 
this is par for the course really.
    I would like some clarification on the 1/4 1/2 wave issue. If the 
secondary is half wave resonant it would in fact have a natural 
frequency of 200kHz? Am I reading this correctly? 

Thanks again,
Malcolm
