     height: 5" diameter: 4"


Secondary: 3" D, 21.5" H

primary: .25" copper tubing .25" spacing, 5" D, 8" H

Power: 12/30 NST, .015uf 20kvdc mmc cap

Topload: 24" by 4" taped triod
                     -or-
             19" by 3" taped triod

Sparkgap: cheap adjustable series gap

I tried tuning it with either topload but, still dont work right, 1 foot 
sparks max, and racing sparks up the side.  Coupling set to .12, I don't 
know what to try next.
