   Hi Chief, the problem is in the main amp section, of that I'm fairly   
   certain. I ruled out speakers for that left-channel-cutting-out problem   
   long ago. However, speakers WERE the problem for the loss of treble I   
   posted about earlier, but it was not loose connections. I was using some   
   humongous White Van speakers I bought used for $20 a while back. I   
   mainly use them stacked to support one end of a pull-up bar. One seems   
   to be not as trebly as the other. But with the system hooked up to some   
   good Kliptsch speakers both channels are singing beautifully. While   
   playing a 100 Hz tone, all AC voltages read consistent from left to   
   right after changing some electrolytic caps and intermediate stage   
   transistors that had inconsistent readings earlier. I swapped the output   
   transistors from left to right. Maybe reseating them might have solved   
   the problem, only time will tell. At the moment both channels are   
   singing. The receiver is open, top and bottom and sitting on one end and   
   that is how it will stay for the next week or two. But I'm pretty sure   
   that no matter how long I wait, the problem won't occur again until I   
   button it up.   
      
   It's not so much that I need this receiver. It's that I feel challenged   
   by the problem.
