Please post a schematic, a sketch, anything concrete that we can use to see what exactly you're doing here.
Enough with the word salad. It's time for another course, hopefully a more nourishing one.
See, post #83.
OK, now we're getting somewhere.
I'm taking the liberty of posting your schematic here for all to see:

So now, would you care to explain in some detail how this is supposed to work?
"no-C2_10us_output_4-graphs.JPG" and "no-C2_20us_output_4-graphs.JPG" and "no-C2_50us_output_4-graphs.JPG" demonstrate in their upper two graphs that a parasitic oscillation has already begun to form within the resistor named, "Bulb100W" since they're oscillating faster than the sine wave generator's waveform in the lower two graphs. At "no-C2_100us_output_4-graphs.JPG", the amplitude of those parasitic oscillations appears to diminish, but picks up at "no-C2_200us_output_4-graphs.JPG" with an altered wave form of spikes which the simulator renders as triangle wave shapes but they're not since there are no plots other than the peaks and the troughs. The amplitude of these spikes becomes unstable at "no-C2_500us_output_4-graphs.JPG". This instability continues at "no-C2_1ms_output_4-graphs.JPG" with an additional feature of a more obvious growth of amplitude averaged over time. At "no-C2_2s_output_2-graphs.JPG", the output remains unstable but with a twist: it becomes a periodic instability peaking at a consistent limit due to a periodic collapse, after which, it quickly resumes its upward exponential growth rate from the bottom end of each collapse. This periodic collapse prevents an unbridled growth of amplitude.
Yet, the peaks are a bit excessive since lightbulbs are not supposed to be capable of tolerating peaks of voltage at 424 and one-half volts. Yet, that's where the peaks of voltage top off at for the resistor which is named, "Bulb100W" in the upper left corner of the schematic. Since heat is the initial impetus for the filament of an incandescent lightbulb to become illuminated, these extreme peaks of voltage might be better suited for an electric heater after adjustments are made to accommodate the parameters of an electric heater?
Making these adjustments, although complicatedly involving several factors all at once, is possible which is what makes this circuit archetype one of my favorites (from a theoretical standpoint) if the mystery of how to build it could be resolved. I think there are four factors to simultaneously keep track of (if my memory serves me): the self-inductance parameters of each of the three sets of coils (counts as three parameters since each of the three sets of coils share the same value of self-inductance among each set), and the frequency of the sine source.
So, those claims of tolerance are not claims so much as they are requirements made upon those components.
The sine wave source is shorted to itself to reduce to a bare minimum its output so as to not interfere with my intention to nurture the formation of parasitic oscillations. For if these PO's don't form right away, then they won't form at all because they will become continuously suppressed. We can't see them on the ""no-C2_10us_output_4-graphs.JPG" graph. So, you'll have to trust me that they are there. It's like a fire you try to start by rubbing two sticks together in hopes of producing a spark to light some dry tinder nearby. The initial moments during simulator runtime are what make all the difference between success and failure.
I use the Trapezoidal approximation engine, rather than Gear or Backward Euler, since I don't have the patience to wait that long.
The inspiration for this design comes courtesy of a single-phase induction motor I removed from a Nostalgia Ice Cream Making Machine which runs its motor off of A/C at 50 watts. If you were to unwind the main coil of a single-phase induction motor and cut its magnetic winding wire into five equal lengths, and rewind them together in parallel connection to each other, then you'd have coils Cu1 through Cu5.
The starter coils for a single-phase induction motor have been renamed, Fe1 and Fe2. The aluminum coil in the upper right corner of the schematic represents the rotor coil of a single-phase induction motor.
The fact that these coils are named after copper, iron and aluminum is purely conjecture on my part in an attempt to speculate how to fashion three magnetic couplings among these eight coils in which three distinct and mathematically precise percentage of couplings are somehow made possible. This was my speculation when I drafted this schematic two years ago.
But now I'm of a different persuasion. I'm willing to speculate that ferrous and aluminum sheet metals might maneuver the magnetic couplings among these eight copper coils since Micro-Cap assumes that all stand-alone inductors will be wound with standard, copper enameled winding wire.
These three magnetic couplings are the byproduct of precise relationships of the following rules of thumb...
- The first magnetic coupling between the five Cu1 through Cu5 coils and the two Fe1 and Fe2 coils, is defined by the ".define primary 0.7" statement in the middle of the schematic to the far right. It must be equal to or greater than the golden ratio of 61.8% and less than 100%.
- The second magnetic coupling between the five Cu1 through Cu5 coils and the singular aluminum coil, is defined by the ".define secondary 0.5477" statement. This value results from subtracting the first coupling from 100% and taking its square root.
- The third magnetic coupling between the two Fe1 and Fe2 coils and the lone aluminum coil is found by subtracting the first coupling from 100% and taking its cube power unless you chose for your first coupling the golden ratio in which case you take the fractional portion (to the right of the decimal point) of the square root of five to be this coupling. But if you were to choose 99% as your first coupling, then you'll probably have to adjust this third coupling up or down by trial and error or else remove this parameter from the simulation file since it will be extremely small: (1 - 0.99) = 0.01 when raised to the 3rd power = 0.000001 .
Just because this design was inspired by an electric ice cream machine motor does not imply that any of these coils are intended to rotate. Think of them, instead, as multiple coils interacting with each other in multiple ways. For instance, due to the lowered 3rd magnetic coupling, implies at least two things: a lowered mutual induction and an elevated mutual capacitance among these three coils since mutual capacitance and mutual inductance are inversely related to each other.
What's with the coils made of different material (copper, iron, aluminum): why does the material matter?
You repeatedly write "tolerates XXXV" on various components: what does that mean? are those the voltage ratings of those parts?
The only source of power I see is your sinewave generator; is that correct? no other power inputs?
The neon bulb could be considered as a "source" since it produces negative current due to its negative resistance.
I did an interesting experiment in Paul Falstad's simulator in which I placed a battery in series with a negative resistor and a capacitor. Lo, and behold, the current went backwards -- recharging the battery -- despite whatever voltage I put into the battery.

But due to a hazard of the circuit blowing up if there was *any* residual charge left remaining on C2 from prior runs, I had to remove it and make other adjustments to accommodate its removal while retaining the characteristic behavior of this circuit.
