A very early run (2006) of my 8 inch coil. This was powered by a homemade transformer and used a blown static gap and 70nF, with a welder as the ballast. <br />Coil has been greatly modified since then (2015). <br />It now uses a pig, 200 bps SRSG, more capacitance (125nF consisting of 230 odd Cornell Dubillier caps) and a much bigger toroid and custom made ballast.
