Hi Nolan,

I run a twin TC.  With two primaries in series, the inductance is twice that
of a single primary.  So the capacitor has to be half as capacitance.  Or,
keep it the same and change the primary taps so there are less turns.

In general L1C1 = L2C2 for the same resonant frequency.  so if L2 is twice
L1, the C2 must be half C1.
