     You have a ground loop set up causing a feedback hum.   
      
   something is not plugged in all the way, or something that was not   
   plugged all the way in, is now.   
      
    A ground loop can be caused by attaching a ground as well as by   
   detaching one.   
      
     A ground lead from your stereo to your turntable chassis may stop it.   
   If it does not, then you need to 'free' a ground which is attached on   
   both ends of a cable, at one end.   
      
     Your "RCA" connectors can get oxidized on the outside.  These are the   
   jacks you plug into with your turntable leads.  They either need to be   
   better attached, or 'less' attached.   
      
     I know it is confusing, but a loop can be created by making a ground   
   connection which should not be there, as well as by not making one that   
   should be in place.   
      
     If you recently hooked the turntable up, you should re-check those   
   connections carefully.
