What is that? I don't know the term.

 

[bremusound]

If you mean „Masse“, that‘s the German word for „GND/Ground“.

So what is pin 6 here then?

 

[MagnetoSound]

MESSEINGANG = measurement input.

It’s where you inject test signal for the head amp.

There is no polarisation input on U67.

MESSEINGANG = measurement input.

Correct or calibration input, as noted in the schematic.
