WV-1 Schematic

[MAXDM]

Hello all,

I have a set of transformers and a choke which were pulled out of a Neumann WV-1 maybe 15 years ago and I am considering building a copy, since I know (now) that those units are particularly appreciated among HI-FI enthusiasts.

Does anyone know where I could get a copy?

I have seen schematics of the WV-2 which is the stereo version, but it is a more complex circuit with two additional pentodes. The original, I remember, had a very simple circuit based around two double-triode tubes

any help would be appreciated
