Hmm...very small sphere or toroid?
That's not good I think.
Very small top capacitance will degrade the performance further.
Remember I want 1 Mhz coil to push to 1000 W .
But thanks for the advice on caps.
I really wanted to use MMC.

But you can't have too much top C, or the fRes will be pushed down. Presumably, you want decent voltage, so the C can't be too big, either. If Cpri is 0.01 uF (10,000pF), and you want 10 times the voltage out(a few hundred kV, assuming you are running Vpri at 30kV), you need Csec<100 pF. (Vsec/Vpri = sqrt(Cpri/Csec), since the energy stored in Cpri eventually winds up in Csec)
