Unknown capacitance?! How's that?!

Is it really so that you didn't calculate ANYTHING about your TC? Not even
resonance frequencies, inductances, nothing?!
You gotta be kidding :)
If this is your situation, I suggest you get (or get back to) WinTesla and run
some calculations with it. Nobody can give you suggestions without exact specs.
of your TC.
