RE: [TCML] Tuning a Tesla Coil with an Oscilloscope

["Phil Tuck" <phil@xxxxxxxxxxx>]

I have used one of those devices when I did a side by side test with the
scope method and the device I used was fairly accurate and I was impressed
with it. If you wanted to tune the primary low allowing for streamer loading
as well, then the scope method may have the edge as that will get within an
accurate 1 kHz.

Heres a great Youtube video explaining the exact method you guys are talking
about.

But after spending too much time and money on sketchy, inaccurate used
equipment I built one of these.
I have personally had great results with this little device, I highly
recommend it..
