I'm new to the list and have been collecting information and parts to
build
a tesla coil.
I am planning to build a bipolar coil.

My current specs are looking like this:

Secondary- 20 Awg wound 56" on a 6.25" pvc form, approx 1700 turns
Primary- 6 turns .25" copper tube flat spiral 4.5" id, 8" od at center
of
secondary
Hv Supply- 2x 15kV 60mA NST (parallel)
Cap- .03uF 45kV pulse capacitor
------------------------------------------------------------------------

>>Topload- 2x 6" aluminum dryer duct 30" diameter toroid, 1 on each end
4"
from secondary windings.<<

Lee,
Are you building a twin bipolar, or a horizontal 1/2-wave?
See my bipolar pics at

Secondary frequency- 112.76kHz
Primary- 232.96 kHz

I used javatc to do the calculations.  If you want to see the complete
output let me know.

Any ideas?

Thanks,
Lee K.
