Has anyone an idea, or experienced what happens on the positions of the source switch of the Dirigent, in the case of an FM stereo version ?

So far i found the diagram of the non-fm-stereo and even there the rotary wiring is unclear.

It seems the fm-stereo only plays on 1 channel when switched to FM-B, no idea if this is ok...

It's OK.

The first FM stereo test-broadcasts was done using two FM (mono) frequencies, one for left and another for right, thus requiring two receivers.

You could use the FM-B setting, in which the Dirigent would receive one of the channels and send it to one speaker output.
You could then connect a second receiver (f.e. a Beolit) to the Dirigents Radio socket and tune it to the second frequency.
The Dirigent would then send its signal to the other speaker output, thereby reproducing the stereo signal.
I deliberately use past tense because the 2x Mono = Stereo broadcasts was soon dropped in favour of the MPX encoding.

Today, you need the optional MPX stereo decoder to produce stereo, in which case the FM-A setting should be used exclusively.
