FISHER MPX 75

I am in the process of adding a Fisher multiplexer to SABA Freiburg 400/11 US export model with the 7 pin multiplex socket. Before I connect it, I would like to make sure of all the necessary changes I need to make to the Freiburg, for the audio output, from the discriminator, to the input of the multiplexer.

The directions for SABA's E12 multiplexer, are a little more involved , than for the MPX 75.

Does anyone have the schematic for the MPX 75, and full directions on how to install the unit on a Freiburg?

Hallo OmerS,

there you can find any informations:

The Fisher MPX 75 uses 230 V DC for B+, the Fisher MPX 77 ( which I have)uses 180 V DC. If someone has the schematic for the 75, I would appreciate it.

I would be able to see what changes, if any, I need to make on my 77, for it to work on the SABA
