Part2- Tuning “Driverless” ZVS Tesla Coil
In this video.- the main point is tuning a double resonant Tesla coil to run off a “driverless” ZVS oscillator. If done right, great output from the coil is possible even with small coils. This rig is built with readily available components and uses a PCB.
On some of the scope shots I talk about interference from the coil getting into the household mains. In fact this “noise” is actually not as bad as it looks and due to both the oscilloscope and the coil itself being my connected to the same isolation transformer. When repeated with the coil connected directly to the mains and using a battery powered scope, then there is no noise at all visible in the house mains.

PLEASE READ:
we are working on a kit. Will keep you posted. We can presently offer the board and all components except the primary coil and secondary. This set up doesn’t need a top load. Our plan is to creat a 3D printed former to use with quarter inch soft copper tubing. Any secondary will work. I’m using a 3.5 inch diameter PVC pipe wound to 6 inches with 34 awg magnet wire. This resonates at 275 kHz with a 100 nF capacitor. The primary is 5 turns 1/4 inch copper tube 5.5 inch OD tapped at turn 3.25. This seems to work well
