Steve Ward's coil...Holly cow. Small but so powerfull. Appears like 6 ft + sparks from about 1 ft tall secondary.
Steve's new coil is excellent :) As far as I know, it's a DRSSTC designed for long bursts, operating at 500kHz, with "agile" DC bus voltage controlled by a Class-D amp. He can vary the bus voltage as the burst progresses, for optimal growth of those long sword sparks.

And it would be interesting to know aproximately secondary top volts needed for those long sword sparks... My rough guess is range 150-200 kV or thereabout.
