In this video I'm investigating what I think can be called an asymmetrical transformer. In this type of transformer we have influence from one side to the other but not as much from the other side to the one.
The source where I got it from used this type of transformer to be able and add current to a voltage source that wasn't able to light up a light bulb. It is then the goal to create that extra current with least amount of input.
This is nothing new (you can search on bucking coils, asymmetrical transformer) but it's the first time for me I could get good results and therefor I share you my setup and test results.
An example of an asymmetrical transformer is the Austin Ring transformer used to power the lights on transmitting towers from grid. This transformer allows power to go from the grid to the lights but block feed back from the RF of the tower to the grid. To be clear, at the moment I understand an asymmetrical transformer as a transformer with one direction influence as talked about here.
The primary connected to grid has ferrite core while the secondary is air core with the ferrit ring in the center to be able and receive the magnetic field from primary.

!!! Important: !!!
This only works when the signal in the grey coil has a signal with frequency that's a resonant frequency of the blue coil.
In my blue coil the best frequency is around 40Mhz but the 8Mhz used in this video is also a possibility but less then the 40Mhz. It's important to search for a frequency where the blue coil is in resonance (or harmonic).
I'm waiting for approval to share a video link to video of somebody else on this. If I get approval I will add it in the video comments.
This are 2 pictures of experiments done before making this video:

You can see in the latest picture why my scope probe is connected with the red-black twisted wire, it's to add very small capacitance in series with scope probe capacitance to have final capacitance be very low.
I could get the wave back as connection with probe directly to the coil by adding capacitors, also adding a plate gave good influence but I first want to look at power setups and then I can see if i can use this knowledge to improve the output in that situation.
