The sec coil is 6.3"dia 17" high wound with 0.2mm wire, top load is 6x2"
abouts, coil itself is actually 113khz or so without topload though ive
never ran it without it so its 107, I know these figures are correct since I
connected the SSTC and my signal generator to my scope and adjusted the
frequency until they both matched on the scope, sig-gen has digital readout,
I thought it would come in handy when I brought it a couple of years ago
since it requires no math to work it all out ;-)
