Neumann TVT Junction amplifier

This is a summing device and amplifier coming from the very first line of germanium transistor consoles Neumann made in the first part of the 60's.

AC151 transistors, inout 8000 ohms unbalanced, output 80 ohms. Runs on 12 volts

You'll need an amphenol 23 pin T2701 connector to wire it.

Didn't had the possibility to actually test it, but it's kind of new old stock module I guess
