If you absolutely have to, you could build your own 10:1 probe.

http://zone.ni.com/devzone/cda/ph/p/id/17

shows how - along with the equation R1C1 = R2C2.
One of the caps is a small variable to do frequency compensation while watching a square wave.
It could be that making C1 fixed with C2 variable is more practical.

Searching ebay for 10:1 probe or 10x probe might turn up something?

Hi Earl,

I would post a pic of the gate waveform with a good probe--if I had a good probe! :-[

The best probe that I have is a 1x cheapie.  I am looking into getting some better x10 probes--something that I've put off for far too long!

I assume the gate waveforms are OK because I can scope across the FET output, and when the FET turns on the voltage drops straight down to zero--very little slope from what I can see.  Also, the FETs are stone cold, even at high frequencies.

I know the above observations will not replace good scope measurements, but that's all I can do at the moment...

Hello All,

Well, the secondary is wound.  How long did it take?  I lost count!   ;D  Winding it didn't take very long, but "straightning" and "spacing" and "waxing", well, let's just say that it took a while.   ;)

The first picture is of the secondary (16 gauge, teflon coated solid, silverplated wire) taped with #35 electrical tape.  Over this I applied the motor tape.  It wrinkled, but still makes a "solid" surface for the last windings, that of the 6 primaries.  (To be wound with 20 gauge teflon coated, solid, silverplated.  The red wire in picture)

Happy winding to all,
Bruce

(I still have to wrap another core after this one is finished!  My fingers are sore thinking about it.)
1.  Lindsay's Stack TPU Posted Picture.  All Wound CCW  Collectors three turns and HORIZONTAL, not vertical.

2.  3 Tube amps, sending three frequency's, each having two signals, one in-phase & one inverted 180 deg, opposing signals in each collector (via control wires). 

3.  Collector is Magnetic Loop Antenna, made of lamp chord wire, wound flat.  Inside loop is antenna, outside loop is for output.  First collector is tuned via tuned tank, to the fundamental.  Second collector is tuned tank to the second harmonic (component).  Third collector is tuned tank to the third harmonic (component)  Frequency is determined by taking the circumference frequency, reducing the size by .88 inches.  Divide this frequency by 1000, and you have your second harmonic.  Divide this by 2 and you have your fundamental.  Multiply that by 3 and you have your third harmonic component.  Tune the collectors to each of these.  Input the fundamental and two modulation frequencies, made to create replicas of the fundamental, second harmonic and the third.

4.  The three frequency's circulating in the collectors, both in phase and inverted, begin to create hundreds of thousands of created frequency's, via intermodulation, that subtract to the fundamental and its harmonics.  This is called "Catalyst".

5.  The three AC PURE sine signals, travel through the amplification stage, Nonlinear, producing the second harmonic and third.  (distortion)

6.  These signals then travel the control coils, are rectified by a full wave bridge, and then sent into the output outer loop as all positive pulsed DC.  This then becomes the output and "collects" the current.

P.S.  The Kicks are harmonic distortion with passive intermodulation.  Can't see it without a spectrum analyzer, normally unless trained to see it on a scope.

Hello All,

I first marked the core for all SIX primary placements.   ;)

And then I wound 28 turns, waxed and taped my first of six primary segments.  I am using 20 gauge, solid, teflon coated, silver plated wire for the primaries.  Winding is from left to right, CCW.

I hope to do one a night, over the course of the next five nights. 

Cheers,
Bruce

Coil is looking excellent, Bruce!

Are you going to precisely space the primary windings like you did to the secondary?  (Not sure if that's really neccessary, just thought I'd ask.)

Attached is a (blurry, sorry!) screenshot of the current controller, displaying fake data of course. ;)  As you can see, I am planning to make the controller able to handle two cores at once for increased power output...I still have a lot of work to go...

Tried posting this last night but my browser kept crashing when I loaded pages here...

Bruce, hard to tell here on this small laptop screen, but that sure looks CW to me. It looks like the camera is closest to the finish end of the winding, and the winding at that end is exiting at the top, When I tried clicking on the image to save so I could open it in a program and blow it up, the image would not download. So I can't be sure. Remember, the way to determine direction of wind is by looking at it from the point of view of CCW wave fronts passing through the centerline of the coil from start to end. The windings should be corkscrewing CCW as you are passing through that coil from start to finish.
