Hi, I've just got a few quick questions.... Are there any/many coilers from Australia on this list (other to me?) and/or are there any Australian teslathons or stuff like that?? and How can I tell if my coil is over coupled or under coupled? I'm running a 4.25" coil with a 30 degree primary on 1350VA and am getting terrible results after tweaking everything from the caps to the ground rods. could over coupling be a major factor here??? thanks
