Is G1/G2 just a Joule Thief circuit?
How are 2 Joule Thief circuits wired together in your circuit?

Thanks

You can use joule thief there. They tune itself to resonance easily and all we need from them is high voltage BEMF spikes 180 degrees to current phase in the choke.

@penno64,

E head to head means you will have room for four coils, you will use only two of them, the fine wire. You will also learn about magnetic current in this test, those cores stick together after power is switch off and stay that way. This depends on the phase of the sine wave is in when power is switched off. Magnetic current will go in the core forever.

Thanks Jack,

I got that, but this is the bit that gets me -

"Then connect the similar coil from second MOT as shown"

p.s. a wiring diagram is what this dummy (me) needs

wire it as shown in the one trafo setup, there is a picture on page 3. If you are uncertain how windings go, then try both ways. But use the bulb for limiting current in case you quessed wrong. There is also picture about this in page 3.

Ok Jack,

Results for first part of test-

L - Coil - bulb - N   =  no light.

Checked all connections and measured voltage at bulb - less than 1v AC

Bulb 60w - dc resistance = 72 ohms

Mot finer gauge wire  - dc resistance = 150 ohms
