The rest of the coil (primary,secondary, toroid, RSG, etc.) is my old coil you
can find at http://www.saunalahti.fi/dncmrc/technical.html, that is:
7 turns of 3/16" copper tube, inner diameter 5.3", turn spacing 0.3". Flat
pancake. Inductance 13 µH. Clearance from inner turn to secondary 0.5".
0.05µF 50kV. A series of two surplus Maxwell capacitors model 30561 0.1µF 25kV
4.33" diameter gray PVC pipe, 19.7" wind with AWG 26 enamel wire, 7 layers of
epoxy paint. Secondary first turn 1.5" higher than primary pancake. Inductance
29 mH, self capacitance 8.3 pF, resistance 56 ohm.
15.7" outer diameter, about 17 pF mounted 1.6" over the secondary top.
550 pF 40kV capacitors (2) from tank terminals to ground and 3 mH toroid
inductors (2) in series with the tank terminals. Capacitor and inductors are
