How can you get flux flowing the wrong way?  Well it must come from the load current creating the mmf that is across the inner magnetic inductor and that drives flux around the closed magnetic path that is inner in parallel with outer.  That in itself is something of a relevation and is hitherto an unknown effect.  But Brad's measurments seem to imply that very thing.

I believe MH's explanation to be mostly correct. Perhaps you are saying the same thing?

Well since my posts # 5777 and 5778 garnered nary a comment, thought I would try once more before throwing in the proverbial towel.

Here is another impulse test method that should kick the transformer into oscillation if there truly is a gain>1.

While it may be fun to discuss  measurement technique as I said before, when you are at the limits of your equipment and believe you have a device with gain, it may be time to try putting the rubber to the road with a real "proof of the pudding" test.

Good scientific method tests from many angles.

ION,

Is the battery wired in backwards? Maybe not. Kinda looks like it though. 

Alright, I think it is correct.

I will give that a go today Vortex-Thanks for your input.
I will have to ask the same as Poynt did-Is the battery around the wrong way?,or are we using a pnp transistor?.

Just a thought on the inner core for my larger build.
Would there be any harm in using a magnet from a speaker as the core?
Would the existing magnetic field causes any ill effects in the operation of the transformer?

ION,

Alright, I think it is correct.

I think the long plate on the battery is usually positive, but the labelling on the drawing is correct even if the plates are wrong.

Basically we are putting a negative charge into the primary (and some also into the secondary depending on the position of the feedback pot). When the transistor releases, the primary and secondary are free to ring at the self resonant frequency.

If there truly is gain or energy coming from somewhere? into the secondary, the normally damped waveform should reach a steady state, and then a core saturating  condition as the energy builds through regeneration via positive feedback, all dependent on the feedback pot setting.

Since this is an AC system with approximately 1:1 windings that are for the most part in phase, adding the positive feedback to the primary is not a problem.

I had to arrange the circuit this way to keep the transformer grounds and scoping points viable. Yes, it just looks upside down, but I didn't want to switch the positive rail, and wanted to keep the FG and scope grounds common to prevent ground loops.

If folks don't like this, there are other methods up my sleeve.

Kind Regards, Vortex1
