Thanks Stefan,

yes, the Pungs-Drossel is an early transductor!

I just love the sentence:
"Das Mikrofon musste sich unmittelbar am Sender befinden und der Sprecher war ständig in Gefahr, sich an den vom Antennenstom durchflossenen Geräten den Mund oder die Nase zu verbrennen." 

Water cooled microphones were hi-tech in those days! :-)

Hello Johan,

Very nice, thanks for the link!
Here is another link which explains something, also with a historic background. 
https://de.wikipedia.org/wiki/Pungs-Drossel
The site is only in German but maybe it translates good in https://translate.google.com/translate?hl=de&sl=de&tl=en&u=https%3A%2F%2Fde.wikipedia.org%2Fwiki%2FPungs-Drossel
