In series, perhaps, in order to get ~15-20kV of dielectric rating?
In your original post, you said you used _a_ 630V cap, which was
misleading to say the least.

Yes.

Yes.

I always recommend building your own TC parts, especially as part of
a planned design process, so that you will have at least some
understanding of what is going on in your coil.

Does the new bank possess the same capacitance as the old bank?
Perhaps your primary LC tank is now out of tune with your secondary.
