It was set up as 1x.

If 10x, I would have had to divide by 10 to get the real voltage figure.

thanks.

err..., i think you meant, multiple by 10.

@MK1:

That video is very interesting.  Folks should look at that and see what maybe we can do with it.  Thanks.

@all

I have found this interesting schematic , searching for the tpu. also http://www.loris-hemlof.com/thetpu.pdf


This one is for fun http://www.loris-hemlof.com/UFO.html  I don't really care what people think about ufo , i am bias since i have seen one years ago.

@all

Look at this it can be done with a toroid. http://www.youtube.com/watch?v=dEEaAwwGTZM

Thanks MK1,

I do think it is just about fiddling. The mag field in/around/from/to/? the center of my toroids has made the light go out and the transistor momentarily stop working on several of my jtc's. I am not surprised to see what this video showed.

Thanks for sharing the link.

If you look closley at one of them (torids), there is 2 inside one wire wrapps, soooo what have we here? I have heard we can piggyback torids one on top of each other heres proof.

Would Jeanna be able to make a double torid of each JT she posted 2day in her amazing circuit?
instead of her single JT torids, I bet there is heeps more power to tap out of them now. Sorry Jeanna, no rest for you tomorra he he

Congradulations Jeanna, on your amasing success with your present JT.

thanks

Now a hint, begin to think about paralling up the second stages.

Hold that thought, Jim.

I still need to make 2 tiered circuits with the filter and the medium toroids.  (I will skip the "bad blue" and only maybe use the high permeability). .

Then even later, I will be using the MK2 which actually has multiple secondaries on one toroid.

My thought on adding layers of coils and toroids is to go slowly. I think it is all too easy to happen upon a phase cancelling effect by stabbing at coils in the dark, so to speak. I want a better idea of what to expect from small multiplications before I go too fast.

(I always dive right into the deep end, but then, I get out of the pool and learn how to swim - if you get my meaning.)


@theNOP,
I did mean divide. That is about the only thing that is clear in my manual. ... I think...

@Thanks all for smiling at my results and progress.

@All,
please advise.
I asked jesus a while back to make the secondary drawn in a less schematic and more drawing way. It helps to explain with the schematic more precisely what I am doing. If it is unnecessary and too wrong and odd, please let me know and I will change the schematic.

I will be going through the most likely suspects in the next week(s) and posting that schematic over and over, so, now is a better time to change it. The real advantage of using the "proper" schematic is that I can easily identify how many turns are on each side of the primary, and how many turns in the secondary right there in the schematic.

Thank you,

jeanna
