Are you just starting out? If so I would respectfully suggest
that you use a neon power supply until you get your feet wet.
Plate transformers and pole pigs require extensive ballasting/
control circuits before they can be safely operated.

See my Tesla References file for reprints with excellent
drawings/discussions of rotary spark gaps. We also need to
collect some digitized images of some of the gaps used by the

These are not too bad, though plastic film caps are better. We
prefer a capacitor with a pulse rating.

> How about vacume variable caps?

Typically vacuum variable caps are too small in value, not pulse
rated, and expensive. If you have some atypical caps then you may
find them useful.
