i built the mag amp dubble toroide


does it look correct?

ist!

22ga 

dc winding 16 turns x2

ac winding 17 turns x 2

[Mk1]

@ist

I think you could go , more turns on the ac side like 1/3 dc , 2/3 ac , also since it take one wire for dc switching 2 toroid , the jt has 2 wire so 4 core would be nice , it would also mean 4 ac coils to rectify , also condensers are ac caps ,

The jt is closer to a mag amps , then a regular transformer , they don't share the same property , interesting , are limitations the same?

xee,
It is not that it is not working for me.

There are too many things that changed between what I have been working on and this newer set of ideas for me to know what made them better, indeed, to even know if they ARE better.

At one point today, I put a light in the jt ckt in the usual place (as your ckt is) and it was very bright. but it also used more amps. You have said that your ckt takes very little, but also that the light is dim. Maybe that is what I saw.

I will try with all these parts again with one of the other toroids whose properties I already checked out.

I will make some attempts to change only one thing at a time. First, I will get my order of toroids which has different kinds but also has 4 more like the ones I used for the MK1 and hybrid.

For instance, I will add only 1 cap at the base of the transistor. Already this is 2 parts different from what gadgetmail has because he has been using the PNP. So, I will make that work and check it out.

Then I will add a cap at the battery as you have done, and see what that does.

Then a second cap at the transistor base if nothing is yet improved over what I had before.

In all of this I will try a PNP which I did tonight too, and the 2222 and then I will wind one of the newer rings. One is twice as big as the others.


Thank you for all your help. I am sure I will be asking you dozens of more questions. I appreciate your ideas and advice.

ok bro ...

4 cores you got it .... 

i will find 4 the same and i will make mods to my coils ..  1/3 2/3 .. dc ac ...   but

b4 i do this do my windings look  correct  as well the wireing ..            ?

ist!

ok so i will make 4  2 wound the way they are showen and 2 the exact oppsite..

yeah, I think this is right.

What limitations are you referring to? I admit I didn't read all that page, I will go back and read it.

good find, btw. At first, I thought it was too far afield, then I realized it is really close to the jt.

It has been under our noses for so long! But now, we need to figure out how to mod all the electrical things in our lives to work on this high freq, low amps. mmmm more fun.

thank you,
