   Thoroughly clean the pinchwheel. It could be accumalating microscopic   
   bits of ferrite embedded in the rubber. Chech one of the tapes on   
   another machine as if that is the case you will be corrupting all your   
   tapes each time you play them as the ferrite is in a sense recording or   
   deleting microscopically on each passage
