Prototype Twin Coil
This Tesla Coil was my first attempt at making a twin coil. My plan was to build a miniature twin coil in order to prove to myself that I had the theory down. After building most of it one Sunday evening, and substituting parts for the yet unbuilt portion, I concluding that the experiment was a success. After finishing it and extensive tuning, I achieved about a 12" spark between the two coils. Although this was very inefficient, it worked, and I was excited!
I have been having a severe problem
of internal secondary arcing. I have burnt the inside of one PVC tube from
the top HV terminal down the inner wall of the tube to the base.
The arc was so severe that the PVC was melted and prominent branches or
black char appear. The coil is now mostly repaired and fully functional.
