telefunken: Volume potmeter stuck

One of the issues of my Telefunkend Concertino 8 was a stuck volume potmeter: it could only be rotated with force.The potmeter is hidden quite deep. I succeeded in removing it by loosening four screws holding the entire potmeter assembly. You need to desolder the connections first. After taking out the potmeter, you can take it apart and free the shaft. Be careful not to damage the resistive element, it cannot be fixed, see the excellent article by Roberto. I added photo's for reference.
