What is this thing?

Here's a card roughly 8"x5" inches made by Neumann. It has a 2 pin power plug to go to the wall.
Model NK48a 01 Nr. A 416

What is this thing?

Type "Neumann NK48a" into google for your answer.

Let's see, power tx, diode bridge, big cap, couple of smaller caps, transistor with heat sink, couple of smaller transistors, few resistors. Looks like a power supply to me, 48V I would gess from the name. A vintage one and made by numann, nice one! I would have it on my wall at the mixing room!

Now... google says....... phantom power supply!!! What do I win?

Yeah, just after I posted this, I did a search. Any idea on how to hook this thing up? I can play shuffle with the best of them but I am clueless on this type of stuff. Could I build a mic pre and use this to power it? would it be able to power more than one channel? Help please

how do I hook this thing up to be used?

I would put it as exposure, you could use it as phantom and get a couple of channels with it, but not for the whole pre... I don't know where is the output but shouldn't be hard to see folowing traces, you should see where are the 48V and use it as output, just avoid the mains wires when you are measuring.

It's nice thing but isn't hard to build a new one, plus this may look excelent in the wall waiting for people to ask what it is.

so in theory and if I'm understanding correctly, if I built say a stereo pair of API 312 clones, would this Neumann work as a power supply for both or would it only supply the phantom and another PSU would actually be powering the preamp? thanks for all of you all's patience and explanations. I truly do appreciate your taking the time to help.

The card will supply only 48 Volt phantom.

Best to keep it as a museum piece.

Nothing to be gained in using it when you can get 48v for Phantom along with your other voltages from one power supply design, of which there are so many designs out there. Plus awesome vintage tone is not made by a phantom power supply.

hell, if I'm not gonna use it....anyone wanna trade for it?
