Pulled this out of an old 70s LPB broadcast console. It's a simple mic preamp card built around a Beyerdynamic TR/BV 310 007 004 input transformer, date coded 1979, made in Germany. Its a simple op-amp based preamp with a 3-position gain switch (-45/-55/-65 dBm).
Great for a DIY rack build, or pull the Beyer for your own project. I have 2 available if you want a pair.
