With audio demo: Vintage Neumann V472-2 dual mic preamp card - fully recapped - 6 .. 46dB Gain

Vintage Neumann V472-2 DUAL mic preamp card

Tested and fully working, check out my audio demo above.

Beautiful German broadcasting design from the late 1970s.
The V472-2 has a very puristic electronic topology, based on just a discrete proprietary Neumann OA20 opamp as active gain element, and beautiful input and output transformers by Haufe.

The preamp already has been recapped and is good to go for the next decades.
This listing is for the pictured module with the serial # 1193.

The module delivers 6 .. 46dB of gain by design, set via external resistors that go on the edge connector.
This can be raised by lowering the resistors in the feedback loop, R6 and R106.
I've achieved up to around 60dB gain this way.
Power requirement: 24V DC.

Also see the schematic above.
