If you are still learning about Tesla coils (grounding, ballasting, etc) I would strongly strongly strongly strongly discoura
ge building a quad-MOT coil as your first coil. It's somewhat more lethal than smaller coils. Disregard this if you've been playing with high-current HV in the past. TC's will generally not radiate enough to damage electronics. I would not run a quad-pack anywhere that remotely resembles indoors (e.g. a terrace).

I think to use as power supply 2mots with a voltage doubler.For the doubler can i use the mo caps?How much capacitance i need?Also with this dc output i need to make any changes to classic spark gap tesla coil?

Calm down and stop doubleposting; its only been a day. Yes, MO caps work fine. Amount of capacitance you need depends on how much Vdrop you can tolerate at your design current. No, you don't need to make any changes. Also, don't kill yourself. Familiarize yourslef with HV before making MOT coils.

You obviously haven`t done any research and if you try to make a dc coil now it almost certainly won`t work because you have to ballast the ht side or you`ll blow your diodes. Please don`t now post:

It depends on how big you want the coil to be. If you want a large one, use 4; If you want a small tesla coil, use 1. Using 2 transformers will lose a lot of energy without very much output imo.

Why? There are many things wrong with dual MOT stacks, but I've never heard of low power as one of them...

I guess I've just had a bad experience with MOTs. I had a dual MOT setup for a vttc and one of them was just slightly more powerful than the other. When a wire shorted out, I wondered why they were barely giving any power, until the shorted one literally exploded :( When I used Four mots, one of the transformers still fried, but it just stopped working and didn't explode. I think you have more wiggle room with four.
