Can't really call it a stout copper bars/hairpin circuit but it's wired in the same way using the same general setup minus the resonance and low drive frequency. Going to do some more testing with the hairpin circuit but it's still cool to see a flyback transformer being able to light some 120v bulbs. Even though they can produce some powerful arcs I wouldn't normally expect to be able to condense them into a 120v filament to get actual decent light. I've lit bulbs similar ways with high voltage arcs without a capacitor by just arcing to the bulb via the right type of spark gap and electrode. This is basically like the baby inspiration for the Tesla coil and you can see the radiation it puts out via an avramenko receiver. Without the resonance it's pretty similar to using any kind of high voltage high frequency discharges crammed into loads meant for much lower voltage. I know I could light those bulbs brighter for around the same amount of power or less a few other ways so it's less about efficiency and more about the cool stuff that happens at high frequencies and voltage. I can also fully light my 40 watt bulb given the right spark gap and quenching with only around what appears to be 50 watts input power. That doesn't quite make sense to me.
Also, there seems to be only one main difference I can see between a setup like this and a resonant one which is that in resonance it would work much better lighting even the shorted bulbs and may allow me to see standing waves along large enough copper transmission bars. I want to see bright bulbs with the shunt on so I'm going to try a pure AC source if I can get the transformer and the mains is low frequency so that's easy enough.
Based upon what I've seen so far I don't see it too much worth pursuing the flyback transformer trying to demonstrate the shunted load running but you can still see some cool effects and light bulbs. Before trying lower input frequencies I'm going to see what the ZVS driver does with a different high voltage transformer.
