Hi Ed,

I have a video of that coil as well, and it really produced some 
amazing output.  I believe Richard Quick got the "equidrive" 
configuration from Richard Hull and the Tesla Coil Builders of 
Richmond.  Hull used it in some of his magnifiers.  TCBOR also 
originated the "RQ" gap which Quick later popularized.
