3 coils on bottom copper core. Pulsed in parallel. Inductance is a little higher than previous Tesla coil so compwave a little smaller.
Bias is next on Tesla primary.

I put a closeup of your coil.
Your horizontals seem like you took twin speaker wire wound 2 something turns, in two sets per ring. If this is the case then please consider trying this.
Based on each horizontal loop wire turned 3 times.
L - 1 - 1 - 1 Top layer three turns
- 1 - 2 goes to second layer in same direction
- 2 - 2 - 2 - C 2nd layer three turns then to Common
C - 3 - 3 - 3 3rd layer three turns then to Common
- 4 - 3 goes to third layer in same direction
- 4 - 4 - 4 - R Bottom layer
Put all three rings in parallel and run the whole coil in tandem.
Run L C and R off your audio output.
Put the long verticals in parallel or series as you want the output or keep them all separate for now to identify their output polarities before you make an output strategy. Tank it and measure as you adjust frequencies on that freg gen program.
Once yo find the right frequency, play with the phasing.
I would say around 11,0000 hertz range but you will quickly find the sweet spot anyways. Then play with the phasing. Don't use those small coils yet.
Keep a nice magnet around to put it near the coils. If you have small neos like what I used in my moving litz wire video, try putting it in the center of the build.
Nice build by the way.
********* Pulsing coils ********
I have a new way of looking at coils and would like to share it with you.
Man if I noticed this years ago, I think it would have saved us so much time.
First of all we all agree that a scope will show the waveform of voltage/current activity or frequency responses at the scope point. OK so take any coil that has a center tap. Pulse one end and scope that end, you will see the response. Put the scope probe on the center tap and you will see half the first response. Now put the probe on the other coil end and you will see NO RESPONSE. On average, half the coil responds, the other half does not. NO matter if the coil is a straight piece of wire, a one turn loop or a 100 mile long wound coil, only half of it will really responds to the pulse. That is because the side that is connected permanently to the coil has already biased the complete coil and upon connection it will simply recede back into its half of the coil when the connection is made. It does not have to respond since it is already at its maximum forward position.
Remember in my pulsing coils videos when I pulsed the toroid coil and placed a Litz wire loop over it to light my LED, the LED would only light at a specific cross section and by moving it slightly off, the LED would not light up. Not knowing this, the loop was either on an active or non-active side of the coil.
If you want to have a strong pulse "reverberate" through 1 complete coil, or a complete Otto mode quadro coiling system, or whatever coiling system, YOU WILL ALWAYS NEED TWO IN SERIES. The pulse enters the first coil and thinks the complete first coil is only half of the total of two coils. So the pulse passes the coil completely. Then you pulse from the second coil side and now the pulse thinks it is only half of the total of two coils and passes it completely. You can have identical coils in series or two different coils in series as long as they are complimentary in inductance.
Telsa did this in the Tesla Ozone Patent. Two coils in series so the primary of the working circuit really was pulsing through out the coil and not only in half the primary coil. The capacitor discharge flys accros the primary and lands inside the coil of high inductance. Almost all the maximum level of the discharge is in the primary. Now I understand Teslas' logic for this.
Just think of the FTPU. Center toroid has two coils. There are two rings. There are two overwound coils. Always two.
The center toroid has two coils in bucking mode. If pulsed from one side, it will have only one of the coils active. So you pulse for one side, then the other side, and so on. The electronics to do this is above my head but maybe with an H-bridge type, or a simple pulse that splits with knowledge of the coils.
Romero's wheel uses drive coils. Two in series so I know that at least one of them is being used 100%, otherwise you are stuck with 50% of each coil. I know, some will say the 50% of one coil is still 100% of the energy put into it. Yes, but you are better off using a little more energy with two coils and have then each work 100% for the effect. Also with drive coils pushing against magnets, always pulse on the end that starts the wind closest to the core. At least if you have such a single coil that is only 50% active, put the active half nearest the core and if you have to switch the polarity against a magnet, then turn the coil itself and don't just switch the wires.This is where many go wrong. lol
So, to summarize lets look at a simple loop. Remember those?
When pulsing DC from one end....
1 loop makes half an active loop,
2 loops in parallel but offset 180 degrees will produce two distinct half active loops.
2 loops in series makes 1 active loop,
2 1/4 turns of a loop will make a 1 1/8 loop active loop.
Think of this. If you wind a primary on a toroid core of let's say 10 turns, then continue the wind but off the toroid for another 10 turns. Pulse on the side of the toroid and the pulse will travel accross the complete coil half that is on the toroid.
If our scopes do not lie, then electricity does not travel in a circuit. It just permeates conductors or better still, electricity is two biasing potentials that just have one goal and that is to meet and annihilate each other. This way, both return to the ether where they came from in the first place. You can see it in thunder clouds. The cloud is a loop of negative potential, the ground is a loop of positive potential. When the cloud gets as strong as the already immense ground potential, the spark starts towards the Earth, but the Earth, with a sigh of boredom toward the clouds' tirade, always sends its own spark upwards to meet the clouds' thunder bolt. Always, always and always. Electricity does not travel in one direction. It leaves both battery poles and advances into the circuit to meet at one circuit dependant point, usually somewhere in a coil because the coil has much more inductance then any other component so the chances of meeting there are greater.
One day when someone invents the NEGATIVE DIODE, we will realize this and it will open up a whole new world of electronics. I would call it bi-directional electronics.
I have been spending some major time on looking for things in EE we are doing wrong because from all the efforts, there must be some very slight errors that produce a major lack of effect. Small things, seemingly insignificant things, without the foumulas that are man derived and formulated to fit so well our reality. Look at the effects for what they are in real life, compare these to other natural phenomena to see where we are going wrong in our quest for YES "overunity". So there is definitely more to come AND MORE TO BETTER UNDERSTAND.
So when you plan to pulse a device, think that only half of it will respond.
Now, if you pulse both ends of a coil at inverse on/off, then when one side is on the other is off and there should be nothing going on at all. But if each side is adjusted so that they share a mutual on time that overlaps, that will be the real on time and the coil will now respond in both halves without an outside assistance off an added coil in series. The overlap window is very small. Otherwise if pulsing from one end, add another coil in series to it and see how it goes.
I cannot remember Tesla ever stating this outright like I have, but when you look at his designs, it seems like his was instinctive but he had to know this otherwise he would never have wanted to invent something better, like AC, that sort of takes care of the problem to a certain degree, but not completely since he was not dealing with square waves. That's why I suggest you try your above coil with sine wave audio as an easy start. Then advance to square waves but I don't know enough about the EE end to say how. Maybe with two H-Bridges one on each end with one slightly off.
wattsup
PS1: The guys that could take immediate advantage of this are those playing with JouleThief designs. If you have a 5 turns primary simply add another 5 turns to it but off the core. Pulse on the core end of the primary. see the difference. At five or more added turns, this will not change the inductance that much but now, it will make the primary that is on the core fully active. lol
PS2: Man, I am just waiting to be clobbered now.
