I have seen variable tuned capacitors on E-Bay.  Think they are used for
radio transmitting stuff, or whatever you can dream up.  If you could build
one of those such to with stand the high voltage it would be a pretty cool
way
to do some fine tuning.  Maybe even motorize it so that you could fine tune
on the fly.  I have never tried it, however have thought about wanting to do
it.

Cheers,
Bill
