I have begun my physical model of GKTC1(tuned coil).
I start with (5) 23 foot lengths of 30awg magwire.
The first wire length is wound on a 1 inch height of 4 inch diameter sched 30 pvc(the thinner stuff) for 20 turns with about 4.5 inch leads.
Do not cut the ends but tape them down.
The last 4 lengths are the 4 control coil segments of 30 turns each.
Fold each one in half to get the middle starting point and then wind in both directions RHR over the pvc and the collector coil.
Graduate the windings so each one takes up its whole quadrant of the pvc.
Do not cut the ends but tape them down.
And use a lighter to remove the varnish from the ends.

The control segments are jumpered equivilant to Tesla 390721 bucking coil transformer in the lower right hand corner of the patent diagram.

Now the collector and the control coils are the same mass.
This is a single layer.
I am going to drive this with a 555.
This is also used to verify the calculations and the application I am building. One should be able to change the wire gauge and get a TPU built from a spec sheet. We will see.
30 awg isn't tiring on the hands as it is a flying wire mess to deal with, besides being hard to see.

More updates later after I fire it up.

--giantkiller. I need a break right now.

Finally some tuning.. Thanks for the pics GK! Looks great.

This may help some folks understand coil winding     http://www.ee.surrey.ac.uk/Workshop/advice/coils/air_coils.html#flx   @ inovation - good luck on your coil looks good . The lighting control usally runs at 2 to 5 MHz - be careful not to heat up the mofets.  @ gk looks good was looking on paper with 2 coils like your setup it would be interesting to see what a coil 6 wraps around the middle as sorta a bias coil.  Thank You Mike
