Hi Oldie Goldie,

I have 2 RCA 6BT Farm sets that have a similar concentric dial setup.  Funny, the condenser looks similar to the Philco.  This setup may have been common to several sets, even a lowly Arvin 4 tube "Rhythm Baby" job that I have the chassis from.  On that one, someone got frustrated and soldered the 2 shafts together.I think that the 3 ball bearings act as the planetary gears in this setup.  In reviewing TV Man's thread, I think that there may be a clip that is supposed to hold the thing together.  the following pics are from the thread from TVMan.  Is it only the inner shaft pulling or both the in er and outer.  If both the inner and outer, then the clip is missing.  If only the inner, then there is something else wrong.

   
   
   

Hope this helps.
