Does anyone have any experience working on a Neumann WV2a phono preamp? Looking for schematics, potential mods, etc.

No experience, but I found a reasonably readable schematic:

I believe it uses a battery for cathode bias.

AFAIK, its a Nickel-Cadmium-Akkumulator, developed by Neumann.

Seems like a few folks are using NiMH batteries in their place.

Those things are with a lot of money. I'd think twice about modifying it. Because of that unit the Neumann VG1 amplifier racks are unaffordable as cutting racks. The phono pre is worth more to audiophiles than the complete rack is worth to cutters.

The guys who own it want it back in shape for sale. It was part of a whole collection of cutting lathes and other stuff from the 50s. I’m gonna give it a quick look over for them.

If there is a list of "other stuff" for sale I'd like to take a look at it.

Sure thing. These guys are selling off as much stuff as possible to help pay for rebuilding their old Neumann lathe.

I hope the lathe guys have a supply of lacquers.  Otherwise they just have a huge doorstop.

I have restored a lot of Neumann lathes. I have a lot of little hard to find things.
