I need a 8pin neumann cable. Original neumann cost around 250€
Aftermarket cable which uses 8pin tuchel connectors and sommer octave cable costs about 100€
but i could get the connectors and the sommer octave cable for about 50€ and solder myself.
Just one problem the cable is only 7pin and the connectors 8pin.
Anybody know what wires get soldered to what pins on the connectors?

You probably want to say the cable has 7 wires/conductors and not pins.
Probably is 7 conductors plus Shield.


To know the Pinout the best thing is to check the schematics,
what microphones use that cable?
Get the schematics for those mics and the pinout will be there

I don't like to discourage diy on this forum, what is your time worth?
upon reread: cable is '7pin'
is that 7 conductor, plus shield? you need the schematic for the device/mic
what is the mic model?

The cable is going to connect an m149 with the n149a power supply.
The cable is a "sommer cable octave tube"

Heres the description
with our SC-Octave Tube which has been custom-designed for the connection of tube microphones or remote-controlled studio microphones. It has a total of 7 conductors, two for the supply voltage and the others for parameter-variable directivity, sensor (measuring) line, heating, and the voltage supply for the tube capsule. These five conductors consist of 72 superfine 0,05 mm single wires and guarantee a linear transmission and high flexibility.
Owing to its 100 % coverage shielding (helical copper mesh screen + AL fleece) the SC-Octave Tube is perfectly protected against all kinds of interference.
It is ideal for connecting Neumann, BPM, or Schoeps microphones.
