MG> Glenn, my current big coil is bifilar wound with two 24 ga wires. This
MG> winding is approximately equal in surface area to an 18 ga. wire.
MG> The main reason I did it is because I had a TON on 24 gauge wire on
MG> hand. It works fine, I get 8 foot point to point discharges outside
MG> in the driveway at a power input of 5kva.
MG> The coil is 8 1/2" in diameter and the winding length is 30" at about
MG> 750 turns, with a 6X36" torus on top. (130 Khz.)
