Hello everyone. Just as the title, i wan't to build a 3kV adjustable power supply, but i can't find anything around that may help understanding how to do it. I don't need any high current, simplest and cheapest as possible. I would like to have some DIY tutorial, diagrams and more.

Yes !
You may use a light dimmer, 120V, 500W and Microwave Ovem Transformer . The MOT receives 120V and transform to 2200V . Remember that one secondary HV lead is connected by the manufacturer to the transformer core. The primary is to be connected in series with the dimmer.
The mot you can find easyly in the street or in the Enviromental Day Party. No cost. And inside the mot a lot of usefull components to do HV. ! The dimeer is$$ 5.99 +tax
It is appropriate to put a 4 amp fuse, 20mm of copper wire # 27 (0.36mm diameter) can perform the 4 A protrection with perfection
Regards !

Edit : the 2200V refer to RMS voltage, or 3100 volts of peak. Using the microwave capacitors and microwave rectifiers you may double this voltage (6200V)

wow that's fantastic, thanks a lot. I think i'm gonna go around looking for some microwave oven. I've been looking for infos around and having a mot would be fantastic. I'll let you know when i find one. Thanks

Thats DC don't you need AC and what will you be using it for?

I think it will be ok AC 2200volt dimmerable, it's already a good voltage. What i'm going to do? Actually i don't know, but it's nice to have a high voltage AC out. I can always correct it with a diode bridge.

Remember that when using the dimmer, the output voltage will no longer be a sine wave. The peak voltage will stay for the most part, so eg. the rectified voltage wont change much and then quickly as you regulate towards zero.
