Tell us about yourself!
I'm thinking about building a VTTC following your schematic. A few years back I bought a GU-81M, so I will finally put it to use, but I have a few questions. First of all, when I input your values to javatc I get a resonant frequency of around 885khz, far from your 350khz. I am in the US so no metric lol. I am going to design a coil that is based loosly off your dimensions, just as a baseline.
