This scheme is exactly what i'm looking for ! I didn't find it anywhere else.
Unfortunately the scheme size is really too small so unreadable.
Have you a better picture ? It would be great for trying to repair this board.

Fab

Here is the original "DC CONV2 DMG" board. Problem is, I can't identify everything. For starters, the large barrel shaped part completely eludes me and 3/5 of the diodes have absolutely no markings. The transistors are labelled but the code for Q4 could potentially point to an NPN or PNP.
And since I can't figure out what the big part is, simulations in LTspice don't do a whole lot for us.
