Coil Specs



	Hello,

	Here are the specs for my first coil:

	Line Xfmr: 15KV/30mA Franceformer (NST)
		Power: 450VA
	Capacitor: LTR MMC-Approx. 0.0075 microfarads -at- 42,000VDC
	Primary coil: Helical-5.5 turns 1/4 inch copper tubing, 1/4 inch
spacing
		Height: 3 inches, 3.5 inches to top of arc ring, spaced
approximately 1/2 inch 				inside the primary
		Diameter: 12 inches
		Primary inductance (max): 15.43 microhenries
		Primary resonant frequency (min): 556.8KHz
	Secondary Coil: 696 turns of 26 gauge wire on a 3 inch diameter form
		Height: Windings: 12 inches, overall: 14.5 inches (0.5
inches on the bottom, before windings, 2 inches after the windings)
		Secondary inductance: 8164.31 microhenries
		Self-capacitance: ???
		Topload: 4 inch OD, 1 inch cross-section toroid
			Capacitance: 4.418 picofarads
		Secondary resonant frequency (max): 861.97KHz
	Spark gap: Richard Quick style gap-3 gaps
		Firing voltage (input to Xfmr): 110V

	No safety gap yet, and I won't put in chokes.  Feedback?  Anything
I need to change?
