The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.

@radhoo I plan on making another video, just haven't gotten to it yet.
@Littleventure They should work OK. The first time you plug this in use an atx computer supply. That way if there's a problem unlimited amps don't go through the fets and kill them.

More amps = better quality sound from my observations.
My circuit puts out 10kV @9mA, I still have to measure ho many amps are going in. The flyback doesn't even get warm, but the primary coil sure does. I had to change the coil to some 14ga litz wire. It helped cut the heat, but it made no difference in sound quality.
I can draw the arc to about 2 inches, but at anything more than 1 inch the music disappears.
By the way, the circuit runs fine with a cracked (and glued) core. Yeah, I dropped it.

You don't need thick turns of wire for a zvs. I used 22awg magnet wire on mine, and I pushed 1.3kW out of the FBT. You should reakky use litz wire though. Look at the inductors on a crt board and you'll see it's braided litz wire. Unwrap them and you have about a yard of it to use for whatever you want.
As for the 555 ic, I have some made by signetics 30 years ago. Maybe those won't die.
1.3kW through a flyback?
Would love to see some vids of this. What was the input into the ZVS voltage and current wise?

I plan on making a video soon, but input voltage was 36V and the current was too high to measure with my multimeter. It was a standard computer monitor flyback.

You know the voltage output drops when drawing current (to a low voltage when shorted) so the output power is not just the product of the peak voltage and peak current. Power is the product of the output current and voltage at the same time.
