Graham Gunderson's Energy conference presentation Most impressive and mysterious

[Spokane1]

Dear All,
Here are some additional photos of Graham's H-Bridge that was used at the presentation.
Some additional notes:
The custom power transformer is driven directly from the IXD driver chip with no MOSFET employed.
The small transistors (8 each) seen on the center power supply board are emitter followlers.
The commercial Half Bridge circuit (Blue sub-circuit board SOIC-16) has been modified with the addition of surface mount capacitors to provide the +20 and -5 gate switching voltages.
The input voltage to the H-Bridge was 12 VDC provided from a 300 mW (for all the logice and gates) wall wart.
Enjoy

Dear All,
Does anybody out there have any knowlege of this torroid winder machine a Jovil JV150. According to Goggle it is designed to wind small torroids up to 8 mm in diameter (smaller than an dime) with up to 9" of three conductor wire.
This machine has been donated to Graham to promote the construction of his next generation of driver power supplies for the SiC MOSFETS, however a manual was not to be found on a simple Goggle search.
If this machine can be made operational it may really speed up availability of the high speed driver circuits that are used in the Implosion Transformer Device.

Here is a link to the company support site.  I didn't see a manual but there is a listing with email address and phone number for a dealer in the U.S.

Here is a video showing a different model in operation.  Maybe it will help in figuring out how to use the one he has.

Dear citfta,
Thanks for the tip. That was going to be the next step, but it appears that the original US company has been bought out by a Chinese corporation. It might be really tough getting documentation for a discontinued model.

I have bigger models of Jovil machines but not the one in the photo.
I remember that before being called  'Jovil" that company went by a different name: "Universal".
