Joe,
Nice looking beast. I am particularly interested in the toroid and I
wondered how accurate JavaTc will prove to be with a toroid of that tubular
design, have you actually measured the resonant freq with a scope etc. to
see what you *actually* have? The bare secondary coil on its own would give
105.42 kHz and I wondered how much capacitance those tubular toroid's give,
when compared to an equivalent sized conventional solid toroid.
Looking at the measurements, you inputted it seems you have the equivalent
of a 12 x 48 inch toroid with its centre line at 84.375 inches. With a
conventional top load, this, along with your secondary, would give an
overall freq of 65 kHz so according to JavaTc there is little difference, as
it gives you 66.14 kHz for the tubular one.
The specs I used are:
----------------------------------------------------

6.375 = Radius 1
6.375 = Radius 2

4.37:1 = H/D Aspect Ratio

120.62 mH = Les-Effective Series Inductance
117.257 mH = Lee-Equivalent Energy Inductance
