Re: [TCML] Re-visited - Newbie question - Where does all the energy go?

Peter,

Maybe there is another coiler in your area that could visit you and look it over. Where are you located?

Do you have access to an oscilloscope and signal generator?  It would be good to check the as built frequency of the secondary then set the primary to match that frequency plus about 5%. That would insure you are tuned close to optimal and not on one of the resonant frequencies... 

 If you don't have access to the test equipment a local ham radio club usually has someone more than willing to bring their gear over and help out. In fact they love a new challenge especially on old technology and it gives them something to talk about on the radio....

Regards,
BrianB
