833A Vacuum Tube Tesla Coil (VTTC)

Vacuum tubes may be an old technology that is slowly being forgotten in the modern world, but there are still some really cool applications for them, including Tesla coils!

This is dangerous! Do not try this yourself unless you are experienced working with Tesla coils and high voltage electricity!

This Tesla coil is based around a large vacuum tube known as an 833A power triode, sometimes called the "cookie jar" triode, because it looks a lot like a glass cookie jar. These tubes were commonly used as amplifiers in radio transmitters, prior to the invention of transistor based amplifiers. Vacuum tube amplifier circuits are a more advanced way to drive Tesla coils than the traditional spark gap switching method, and result in very different looking arcs/streamers than spark gap coils.

The circuit for this coil is based off of the design of Steve Ward's VTTC-5 coil (https://www.stevehv.4hv.org/VTTC5.htm). Huge thanks to Steve for all of the information, including circuit designs and Tesla coil theory, that is so well documented on his website (https://www.stevehv.4hv.org/).
