Re: Not enough pimary inductance?
"I had heard the well circulated wive's tale that off axis L would waste
energy. This test graphically proved that it does not.
The practical conclusion is that it IS technically acceptable to place a
high quality air core tuning coil in series with the Tesla coil primary
coil in order to achieve 'fine tuning' without throwing away hard won RF
tank circuit energy!
Real valuable knowledge gleaned by the actual doing.

That is, indeed, an old wive's tale. What will happen, however, is
that the coefficient of coupling will be reduced. However, that doesn't
mean any power will be lost, unless the added coil is lossy.
