The  Yoke had  very  much uncommon   chemical components in that  yoke.
It is considered by me as  dangerous  although  we didn't have tools  of analysis of that structure at the test site.
The side effects :
Everyone from 6 experimenters including me but possibly excluding Antannas who was   documenting  the event was affected.
Aidas the young guy start to lose hair and experiencing   terrible headaches.
Gintas was the oldest of us. the same  but little lesser,  he didn't lose hair.

I didn't start to have health problems immediately.

As Aidas mentioned that he  had previously problems while we tested  halogen  lamp acting as a load, where I was instructing Aidas over the internet
video   conference what to do ...
The positive effect of that   made me to go to Lithuania to see it  by myself.
At the very first minutes  in Kaunas  Test room Aidas  wanted to stop testing  and I was  afraid that my trip
all expenses and discomfort will be wasted. So I placed my head nest to the yoke under test and said that  this is only Aidas imagination.
I recall I felt hot, yes hot  right after placing my head  next to  yoke under  the test (in about 7-10 minutes  after ..)

I had terrible  headaches and I was losing balance for a about 3 months prolonging to 5-6 months  after the Lithuania Experiment.
So  I was able to walk, but changing position of the head made me to lose balance or when bending or  trying to touch my feet with fingers I was falling down..
Well not so much  falling down but I was looking for something vertical  next to me  in case..
Changing position from vertical to horizontal was a challenge, this ended definitively with free fall  .

Than in 1960 Russians  were trying to add to the powder  something more.
How ferrite cores are made today .

this one  compacting metal powder shows exactly the same process as is used in cintered ferrites
https://www.youtube.com/shorts/QZThsst0RIg

Ferrite is a polycrystal, sintered material with high electrical resistivity. The high resistance of ferrite makes eddy current losses extremely
low at high frequencies. Therefore, unlike other magnetic components, ferrite can be used at considerably high frequencies. Manganese-
zinc(Mn-Zn) ferrites can be used at frequencies up to several megahertz.
The basic ferrite materials are obtained in an extremely high purity. These materials are mixed, calcined, milled, granulated, formed by
pressing, and sintered at a temperature of 1000°C to 1400°C, then machined. The electrical and mechanical properties of a particular
ferrite material are obtained by the material formulation and the processing applied. Extraordinary exacting process controls are required
to assure the high uniformity of product for which TDK ferrites are well known. Through the above processes, ferrite materials can be
optimized for specific applications.

You are taking  fine  iron  powder, wet it with water, place that into huge ceramic  horizonally rotating cylinders  and let it rust for  24 hours
while rotating. Than you soak the water , let it dry . The rust is preventing  the powder  particles  from conducting.
Than you place that powder in the form giving it  desire  shape ,  you add some  bonding compound and  press it  with
hydraulic press 500kg pressure . Than you  have very fragile form  called green stage ferrite.
Than you place it into  furnace heating it till it particles bonds into solid stage.

I add some more pictures and picture with original schematic

It is this yoke  experiment that made  all my trip to Lithuania beneficial knowledge wise
In this part of experiment we got subsequently  600W out of two 1 Wat generators and than 1kW  dissipated on the load halogen lightbulb.
I witnessed only 600W. In the time of testing 1kW load  I fall asleep.

I'm looking at number of views under  my photos.
It looks like it is not much of interest as of yet
should I stop it now?
you don't want it ... you  don't have it .. simple  like that.
I'm working on it  second day now... my time is more important to me...

Thank you so much Wesley.

You have been more generous than I could have hoped for.

PLEASE PLEASE add more if you can find the time and patience.

Even though there are not many views I am the one who needs whatever information that you can provide.

Much gratitude.
