designing VTTC

[Matyáš Suchý]

hello, I wanted to ask how I can create my own circuit for VTTC, I'm 14 years old, I've already built a vttc from a GU-81M tube but it was according to the diagram from the internet, now I would like to make something from GU-39-B, but I don't know what kind. values of capacitors and etc to use or what exactly it depends on so I would be very happy if someone was able to help me

Hi Matyas and welcome to HVF!

Please do include some more information, like pictures of your first VTTC and maybe list some of the stuff you already have, that you think you will use for your next VTTC.

I got some equations on my VTTC1 article, on how to calculate load impedance and resonant capacitor, according to chosen tube: https://kaizerpowerelectronics.dk/tesla-coils/kaizer-vttc-i/

Generally there is not many guides on VTTCs, as its all really just tube amplifiers from old tube books. There is thousands of old free tube books scanned and free for download at: http://www.tubebooks.org/index.html

hello, my mistake, when I wrote that I built VTTC, I rather meant that I was just working on IT And that is why I would like to know how to design VTTC to find out the values I need
