I have tried this:
http://www.coe.ufrj.br/~acmq/tesla/mres4.html
This is the case where the resonator is connected to the top of the
primary
coil.
With a tap in the primary, the system would work too, but the number of
cycles required for complete energy transfer becomes associated with the
voltage gain in a way even worse than in the directly coupled system.
A high voltage gain would require many cycles for complete energy
transfer, as in a regular Tesla coil with low coupling.

It would be better to invert the connections and connect the primary
capacitor to the tap and the resonator to the top of the coil.
