   Does it become good and bad at the same places each time you play the   
   same tape?  If it does, the problen is in the recording.

   Make a probe to feed the signal into on a high-impedance, high-gain   
   amplifier and trace the signal through the machine.  Is it diistorted at   
   the playback head?  At the volume control?  At the line-level output?   
   At the loudspeaker terminals (you could have a damaged loudspeaker)?
