Peter -

How did you test for the secondary resonant frequency? Did you use the
bottom of the secondary connection test. This test is shown in my Tesla Coil
Construction Guide. What were your secondary parameters? This is a very
important test for all coilers. Did you check the capacitance reduction of
one of your toroids with this test? This is also an excellent test for
E-Tesla6 with a toroid on the secondary.

John,
       last weekend I finally got a way to directly measure the resonant F of
one of my secondaries, I got 204.8 KHz.  ETesla6 predicted 204 KHz.  Thats
less than 1% error.  Nothing else comes that close.  ETesla6 is the method
by
which everything else can be guaged.  As to the question about the use of
Wheeler and Medhurst, of course they should be used, you don't need the
accuracy of ETesla6 to get a TC to work, just adjust the primary tap until
it works, for that Wheeler and Medhurst+80%Toroid work just fine to get you
into the ball park.
