The Master Of Magnetics "Steven Mark"

I'm not sure marco, because the writing is erased on it, or I can't see it (maybe I'm going blind

I would say use something like NTE2343.  Lot's of transistors should do the job.

Okay  thanks.
i will take a grasp into the scrap box to see if there's anything which will do the job.

I just rewatched all the videos,Ã,  and I noticed something.

The magnet that he uses to "stimulate" the larger and the smaller units,Ã,  IS SHIELDED ON BOTH SIDES, by the iron laminations.Ã, 

There is no field outside of it, or very little, so whether the small toroids have iron in them or not can't quite be determined.Ã,  

I brought a small magnet close to bailing wire, and it has quite some attraction, so I don't know, hard to tell.

Here it is : Turboresearch Volume 3

next chapter is going to be about the out of phase transformers.

Thanks man, an excellent document, the circuit config you have in there is similiar
to this one.  So I,m going to reconfigure and try out the one in the pdf...

Wonder what would happen with a diamagnetic material...
