You are entirely correct in you analysis, but many of the list users are
using specially manufactured capacitors designed specifically for Tesla
Coil work. These capacitors are rated for VRMS, not VDC. Still, as Ed
Sonderman's recent experience pointed out, the caps should still probably
be somewhat overrated.
