Hi List,
     Well, I feel I need a reply on this one. All who were at the Florida
Teslathon last Aug or Sept(can't remember), got to watch the vertical Tesla
coil firing away with the 2 pole transformers tied to it. Lets see now 280
volts at 50 amps...lots of input power. The toobs are rated at 4000 volts.
Mine are running 7500 volts. I really don't care if they last for 10 years.
I have had failures in just about every componet. I have spares. I would
estimate the spark length at 3 to 3½ feet at this power level. The spark is
longer on ½ wave, but looks cooler and sounds meaner on full-wave. With the
discharge point removed the spark danced around the toroid just like my SG
coil. I see Dave McKinnon has already got the date for the 2004 Florida
Teslathon on his site. Since we have it at my house, we're all going to have
lots MORE fun this year. Hey Shad, Michael, Ralph put your $.02 in.

Later,

James
