Dear Teslalovers Hi to everybody, I had better results in terms of sparks lenght and power when a direct link with cable is done between the two references of primary and secondary coils of my Tesla. Isn't ?? What do you think about coupling methods ? What do you suggest to manage the RF ground connection ? I have a simple Tesla passive implementation setup with 300va 11kv 35ma primary HV transformer and 20 inches secondary coil 15pf toroidal top load with 250khz resonance.
