   Troubleshooting Audio Amp

   Hi all,   
      
    I've identified an issue with my Uher tape recorder and I'd like your   
   opinion. There's a problem with the audio amplifier chain. I've   
   eliminated all other possible causes like dirty heads or faulty tape   
   etc etc. So when I'm listening to playback, the quality is frequently   
   varying from 'pretty good' to 'really quite crappy' and I'll expand on   
   what I mean by that. There's a distortion which comes and goes   
   intermittently. You know how vinyl records start off life being really   
   great sounding, but that gets progressively worse the more times   
   they're played? Now imagine if you will a vinyl record which has been   
   played repeatedly with a worn stylus until the recording is very   
   noticeably impaired; scratchy and gritty sounding and you will have a   
   good sense of the kind of distortion we're talking about here. What,   
   in your considered opinion, is the most likely cause of this problem   
   and how would you go about identifying the culprit? Distorted output's   
   a lot trickier than a break in the signal path to track down!   
      
   Cheers,
