Steve,

I think that with careful selection of the size of the capacitors in the 
voltage multiplier you can effectively create the ballast in the multiplier 
itself.  This at least has been my experience using a simple half wave 
voltage doubler circuit in my tube coil.  Lowering the capacitance on the 
voltage doubler significantly reduces the output of the coil.
