OK WE GOT IT NOW

People use them all the time for high votage experiments off the mains, and if your like me, one experiment leads to another ect, ect...

Just a friendly warning because we care about you.

I have been using old aircraft magneto coils 10-24kv,
9-12 volts at 100hz.

You can get old ones free( dont ask me why they save them) at most airports that work on piston powerd aircraft.

Thanks for the advice! im sure you all as I, do not want anybody dead. I have had a close call once where I almost touched the wrong lead in a circuit containing a charged bank of capacitors around half of a farad charged to around 5kv, luckily my friend smaked my hand away which in retrospect hurt less than what I was about to do. It wouldnt have killed me as the path would have just been through my hand, but man, I dont think my hand would have looked the same after that! After that experiance I am extreemly careful in my experiments.

A flyback is another option, you can get quite a large amount of power into them using a mazzilli driver but thats an art in its self.

You should have no problem putting transformers in series, people do it with MOTs all the time for Tesla coils. The secondaries are in series while the primaries are in parallel, but that is with mains, I don't think it would work with low power.

Awesome! thanks, I already looked at flybacks and was surprised at the ammount of coils the cramed into it! Im actually right now in the process of rebuilding one I took appart to learn from. Question, would that circuit give off a wave form similar to....../l/l/l/l/l/l/l/l/l/l/l, ramp generator? and that last one about transformers in series is brilliant! I dont know why I didnt think of that myself, it only makes sense, where I was trying litterally put the transformers in series, with secondary of one connected to the primary of another, it did work, but man, did I ever blow a few power sources in the learning process!

Im not an electrical engineer, but am gettin an engineering degree. I actually may decide to go over to electrical engineering as well, or switch all together as it is my real interest. @ all....Thanks again for helping me out, I dont often post, and usually find things out for myself, but I do spend alot of time here reading, and it still blows my mind that people will go out of their way to draw up diagrams and solutions to other peoples inquiries! You guys rock lol.

With a forum name like Armagdn, you're sure to bring upon yourself a demise to your personal safety and well being sooner or later... considering you are experimenting with HV!!

Not me... I'm saved! Ya know, one of the raptured 144,000 or thereabouts!

Only my son and my dog follow me around in life. The rest of the world is quite safe... from me that is.

I don't think so, although I haven't built one of these myself.
I know that the circuit can deliver quite a lot of power, having the cap there it acts like the primary of a TC, but how exactly it works i'm not sure, I'm not an engineer either, just a tinkerer.

The waves from mine look like the ones in ignition circuits.
A sharp spike with ringing( oscillations) after.

It depends on how you drive it.

We are talking about the Mazzilli driver. Are you also?

well you can get any dc resistance with a normal mulimeter 'cause the resistance is far higher..mabey use a wire insulation checking multimeter?and you have to get the polarity correct or the diode(if is a diode split transformer)will not allow you to read anything

The transformer in a microwave oven is built as cheaply as it can. The windings don't have enough turns to make it efficient. They don't care if the transformer wastes 150W when its output is 700W.
I works at the low mains frequency, not at a high frequency.
