Resistance isn't the main concern in a classic TC sec. It's the number of
turns and the coil radius that's important for high inductance ratio.
Reasonable Q factor but not critical for great performance.
Use 26 AWG on your 6.25 inch dia. coilform for good performance. Run at
around 180 mA with .04 uF capacitor on primary. A good copper pipe primary
gap with 10-12 pipes with 50 cfm cooling fan. .210 inch maximum gap with
NSTs. Use a Terry filter on the NSTs. 14 x 4 or 14 x 5 inch toroid atop
sec. Flat spiral primary.
