Schuchhardt microphone

I wondered how they were arranged electrically. what came to mind was the possibility that they were in say parallel to provide more power output? maybe as a transmitter modulator?

It wouldn't matter how they were connected, Brian, assuming that there isn't anything connected in antiphase for some strange reason.

Series, parallel or series parallel, the output power would be the same although, obviously, the impedance would vary, dependent on the individual arrangement.

Its a shame I cant get it open but even taking the felt off the back I might not get it apart.

If it works, there is nothing to be gained by taking it apart but everything to lose if you damage it, so I'd leave well alone, Dave.
