Hi brian, 
I assembled a cap farm of 50 15uf x 660VAC which I was going to use as a 
3uf, 33KV tank cap. Then I started to figure out how big a tranny I would 
need to resonate with it and gave it up until the day I hit the lottery. 
Some things to consider: 
If you use quick connects, there is always a little resistance in terminal 
connections and corrosion thereon.  R(ac)<2*sqrt(L/C) is required for 
oscillations. 
If you use semicircular jumpers, you're adding inductance L (.5 turn) x 2 x 
66, which may limit the frequency response noticeably. 
Worth a try though, Let us know how it works.
