But seems to me I need additional components like gretz and capacitors. I belive it is challange on its own to build such DC power supply. Any good sources for diy dc ps?

Typically, in the US, these have 480/240 V primary windings and 240/120 V secondary windings, selectable by moving some straps. By setting the straps right, you can get rated current at half voltage (and half power), so you can get 60 V AC (instead of 120 VAC). 60 V AC X 1.414 will give about 84 V DC. These transformers are often found at scrap yards for the scrap price. Likely, you can find similar units wherever you are.
