I can use all of the ac and don't want to rectify to eliminate half of it.

a diode bridge will rectify the totality of the AC current minus the diodes threshole voltage.
the losses with a bridge is ~1.4volts, whitch is the diode threshole voltage of 2 diodes.

instead of this:
/\  /\  /\  /\
   \/  \/  \/  \/

you will get this:
/\/\/\/\/\/\/\/\

a single diode:
/\_/\_/\_/\

that is true, no ferrite will resonnate at the same frequency.
but their resonnating frequency should be relatively close to each other if they are from same batch.

ressonnance have more then one effect, one of them is energy compression.
problem is, you can't tap that energy off without turnning the ressonnance effect off.
trying to use the energy will lower the energy compression effect, if not kill it completly.
if the resonnance is not used for its compression effect, then its other effect can by usefull in a circuit.

if you want to prouve me wrong on this, you will be better trying with Dr Stiffler SEG then trying with a jt.
those 2 are using different ways to basicly get the same end results.

I have scene Dr. Stiffler's stuff but I haven't kept up with it as it was beyond my understanding at the time.  I understand your explination.

Here's my latest coil using the Goldmine 5 for $1 toroid. This is untested, I need to get some other stuff done before I start playing with it. I spent about an hour winding this.

3 Turn Base Coil
7 Turn Collector Coil
150 Turn Pickup Coil

Pickup coil is wrapped up then down. From the end of the Collector coil to the start of the Base coil back to the end of the Collector coil.

Stay tuned... Until then, enjoy the pics!

Dam.. your coils are sooo nice. 

Good job I can't wait to see what that is capable of!

Thanks!

It could have been better if I took more time on it. If you look close you can see a couple of spots where I had to skip an overlap on the pickup on the way back because the alignment was getting off.

Oh well    if it turns out good, I can spend more time on the next one that will have 30ga in place of the 26ga pickup coil and I should be able to put 250 or so turns on it 

Just got done mowing the lawn, taking a break now. Got lots more stuff to do, but I might get around to testing today and we'll see just how good it does 

Also, this new coil was inspired by Xee2's latest achievements. Thanks for the inspiration Xee2
