Nice work. I have the scope out but have been drinking mass quantities of Corona and cant seem to understand the concept of differentials? Please explain!!

@all

I have had a break through of sorts. I Now believe the JT can go over a 1.0! I will soon prove this with the LLA1. I have a good friend who works for a company called General Dynamics he stopped by and took a look at my setup and said I need to move away from ferrite cores. And said something about COP over 1.0. I have done some research and the military is using a JT with different alloys.

Please read this:

The soft magnetic properties of amorphous alloy toroids is improved by turning under tension an amorphous alloy ribbon onto itself to form a winding having a preselected number of turns such that the radially acting compressive stress is minimized. In one embodiment, the radially acting compressive stress is locally minimized by using such a toroid pole-piece geometry that the windings have as little an area of curvature as is possible. In another embodiment, the radially acting compressive stress is globally minimized by turning the ribbon onto itself such that successive turns of the winding are wrapped with progressively less tension.

Exciting stuff! More research shows that the MEG uses the same type of alloys. Here is a link for the Toroids.

@ALL and Altrez

Really interesting !

I also have found some piezo transformer

Ring transformers

The high-power ring-shaped ceramic multilayer transformer is Noliac's patented PZT transformer designed to operate on the thickness mode resonance, enabling extremely high power density levels.

This technology is especially attractive for compact and high efficiency step up or step down applications, such as adaptors for electronic equipment.

Additional benefits include:

    * Very high efficiency (>98%)
    * High power density (>40 W/cm3)
    * Little electromagnetic interference (EMI)
    * Very high and variable transformation ratios possible
    * Integrated galvanic insulation between input and output
    * Working frequency in the range 400kHz to 2MHz

WELL WELL WELL....   

HUMMMMMM ......   

I POST SH!T THEY TURN OFF ON MY SCREEN ON MY LAPTOP..... 

ILL LEAVE IT THERE ... 

IST!

BTW A WHILE AGO I MADE A SEDJUESTION FOR A RODIN COIL  WITH A CRYSTAL CORE TUNED TO YOU GUESSED IT ....    ...

HUMMMMMM

OOOO BUT I HAD TO REALIZE WHO AND WHAT I AM ...  WHY HOW AND ALL THE OTHER QUESTIONS THAT REMAIN UNANSWERED ...

@all

all those that talk about lost in the jt and OU nothing is ever lost , just transformed , those that still can't see , look at those 3 video , like i said all along the energy is only limited by the number of pickup coil .

Now dose a jt transmit , well LoL ...

Thank to Lid and Jonny!
