	The rolled capacitors are a perfectly good way to go for Tesla stuff,
as they're pretty low loss and easy to rebuild; the usual construction
approaches that of the extended foil capacitor and the guys who came up
with them knew what they were doing.  Also big, messy, and no where near
stable enough for tuning narrow band transmitters.  More lately someone
has come on the idea of using large banks of pulse-rated tubular
capacitors in series/parallel.  That's a lot easier to build and works
exceedingly well.  In fact, it's sort of revolutionized the world of TC
building, said world being at least as weird as that of lowfers!  Some
of those guys are running over 25 kW and producing arcs well over 20
feet long! Not the sort of thing that would go unnoticed in the
household or neighborhood..........

See http://www.spectrotek.com for my still pictures and movies taken at
the 2003 Florida Teslathon. The big machine managed to put out 16 foot
arcs with about 17KW input.  Not bad for a rainy day!
