Thank you! It is my very last coil that I made, the years are starting to weigh on me. I fear I am one of a dying breed.

It is really nice, because it is small, but powerful! I was really surprised by the incredibly small primary, which is unusual for that kind of coil. Can you share some more information? Resonant frequency, secondary size and turns, resonating cap.
