Hi all! My name is Paolo Gaiardelli, I'm from Italy. This is my first message to the list. I've got a couple of questions: -I've a 2500V 100mA neon sign transformer, is this ok for a tesla coil? -I've built a 1"ID x 15" coil with 33gauge wire, and I get 3" sparks from it, I guess this is a bit too short spark. Is there any way to get longer sparks using that 2500V transformer? Thank you for your help:-) Paolo
