I was hoping you would ask him in his YouTube comments and on Russian forums that he often participates in.

Please show him the diagram below and ask him whether his transformer is laid out as depicted on Diag.1 or Diag.2.
Also, please ask him which winding terminals are soldered to the copper shields.

According to me the beginning of the coil soldered to the shield and the end of the coil soldered the shield 2 to it ...Lacy...

I just counted turns in slow motion of video.
It appears there was 25 turns on isolation on top of copper foil. You might start with 30 then cut wire down until best results if you get 1:1 pot core like there..

Hopefully that helps

Hello All:

Quick question:

Does this look like the copper foil tape used in the video?

hi HG8AD,

You have a valid point from photo.Same copper wire can be used without using another copper to link to circuit.
But do try to solder little further away from the gap if you are re-creating copper shield.

But your (cavity or gap) looks little funny it should be across the "bobbin area" for both side.Only one\left copper side is correct ,it seems your "gap" is twice as wide as the original device shown in video 4.
Just try to follow the original layout since it's working device.
If your untested version of copper shielding were to fail it will waste the time taken to wind a another coil."It will be as good as starting from scratch,afresh once more.But i got no say if you got time on your side"

hi lost_bro,

Before you actually purchase item have you noticed the width of the copper tape spec "10mm" or 1cm is actually insufficient to cover the cross section of bobbin winding area.
Why not go for thin "copper sheet or copper foil" which can be cut even with scissors and easy to apply for any size of bobbin height.

Once soldered copper wire to sheet after cutting sheet to bobbin spec.Then stick onto place with see through tape or you can also attach very thin double sided tape under the cut copper pieces.
This would be similar to a copper tape.

This is just my 2 cent worth of advise.I shall leave it to you to decide.
