Yes it is.  The MK1 coil winding.  Then, later on it is the Jeanna circuit after she modded it to get over 1,000 volts from an AA bat.

Bill,

I think I found it here:

So here is my BIG Joule Thief based on a Metglas Powerlite C-Core AMCC-320.
It has two oscillators sharing the same core. This is a 12 Volt design and is mainly
for recharging 12 Volt lead acid batteries. The input will be provided from a 120 Watt
solar panel. I have some soldering work to do on this unit before first run. I'm still
waiting for some parts in the snail mail. But I hope to get the unit done this weekend.
Two over-sized panel meters make this unit look quite retro. LOL

@all and Ground loop

I made a video of the Mk1 winding , based on Jeanna observation it transformed the radian tall spikes into something similar to AC waves , but benefit is to be able to load the secondary without losing power on the JT led .

Basically you wind one layer then come back winding the wire between the other wire so you have one layer thick on the top but 2 layer thick in the middle of the toroid .

Thank you for posting this information.
This is what I was looking for.
