Hi! need a powersupply for a MC-preamp. I already have a DC-supply like the one in the attached picture. I want to connect this to the 3045/3094 regulator in the next picture. I guess I would have to modify the DC-supply in some way to make this possible? Also, I need to get one more cable with the small, white connector in the picture. Anybody knows what they are called?

The DC supply is designed to be used with a transformer having two separate secondary windings, not a center-tapped winding.
The connectors on the voltage regulator board appear to be some version of JST. https://en.wikipedia.org/wiki/JST_connector
Also, one could potentially solder wires directly to the board rather than using the connectors.

Thanks! Yes the DC-supply is supposed to be used with a separate secondary windings transformer. Would I short out the DC-supply by connecting V+ and V- ?
You can connect one output lead of each supply to ground, it could be either V+ to ground or else V- to ground. For example, you could connect V+ of one supply to ground, and V- of the other supply to ground.
