Hi David,
                The easy recipe to making a magnifier:
Design exactly as you would for a 2 coil system but treat your 
secondary as though it were cut into two pieces.  To work out its 
(non-top loaded) resonant frequency, sum the inductances of the 
extra coil and secondary coil (call it Ltot), thenm calculate the self 
capacitances of the two separately. Sum those capacitances 
together (call it Ctot) and apply the usual resonance formula to get a 
ballpark resonant frequency for the entire structure. Interconnection 
wires/pipes/straps will tend to lower this figure a bit. Note that you 
must calculate separate Cselfs for this to work. As usual, adding a 
terminal to the extra coil will lower the final frequency.
        For fine detail on designing an optimum system where all 
energy ends up in the extra coil, refer to Dr de Queiroz's excellent
posts on the subject in the list archives.

Regards,
Malcolm
