   After spending the weekend up to my elbows in this receiver it is   
   playing beautifully through both channels and the left channel hasn't   
   cut out since I reseated the output transistors, which I am hoping is   
   what was causing the problem, because that means I fixed it.   
      
   To Tim Schwartz, I can see how the speaker switch may have been causing   
   the problem since it is between the main amp and the speakers, and if it   
   crops up again I will go to that next by jumping around it. I know it   
   isn't the relay because I jumped that and the problem persisted. And   
   looking back at the last time I posted about this 3 years ago I pulled   
   the relay and buffed the contacts with exceedingly fine wet/dry sandpaper.   
      
   And thanks to Dave Platt for the tip about playing a 100Hz tone to probe   
   for AC voltages. That was a real point in the right direction for me.   
      
   All in all, I learned a lot this time around. I may even try to   
   resurrect that Harmon Kardon 930 a friend of mine gave me a while back.   
   It eats 3 amp speakers fuses in one channel.
