Please be nice im having a bad day
i dont understan the electronics i do understand his
drawing combine the transforme and spiral winds
in a ceramic you dont need to build this its already done
a car coil get a good one the ceramic minimises the frequency loss
hope this helps

without knowing how the transformers are wired i can't say if thats right but i am going to post a pic below..
and also the driver you got may be to high of a freq.. i think it runs at 30khz.. you will need lower freq..
also you will have to do something that would be hard without a scope but you may be able to check the output of the aircoil with a meter.. you need as much voltage out of the aircoil as you can get.. with a scope you can see the very tall spikes .. that a meter won't show..
it would be nice if you have a driver that was adjustable with the freq..
i would love to have a function generator.. but maybe later if things get better..
below is how they have to be wired.. on the transformers are hard to get cause you have to know were the beginning and end on the windings are wound..
let me know if you need anything

this is one of my versions of the vta or what ever..
you can pulse the transformers or the aircoils..
if you decide to build it ..

Hi Kooler,
What are your input/ouput measurements ?
