Technical walk-through and demonstration of spark generation from my first dual resonant Tesla coil. I finished this dual 811A vacuum tube Tesla Coil back in late 2008, which dates this back 15 years by now! At the time I finished this coil, my best camera at the time, could only record in 640×480 with horrible noise in dark surroundings. This video is the walk-through and demonstration video I wanted to make 15 years ago, but got done now 🙂
A VTTC is both a great starting point for building a Tesla coil and doubles as a vintage project. You can read all about calculations, design and all construction pictures in the article I wrote about this Tesla coil. You can find it all here, along with the original demonstration videos: Kaizer VTTC I
If you want to build your own Tesla coil, any kind, not just a 811A Vacuum Tube Tesla Coil. I highly recommend to check out https://highvoltageforum.net as a source of great help.
