Ron;

Thanks! I am convinced that these models are capable of some decent sound and I kept noticing that the response to the volume and tone controls kept changing as the radio warmed up. I finally decided to replace many of the resistors in the Phase Inverter and 1st. Audio stages. They were all OEM parts and were 20% tolerance parts. I began checking their values and found many were more than 20% off value, so I changed them. The radio is now playing and sounds better (less distortion even with elevated volume). I will leave it on for hours now and see if anything else develops. So far it is noticeably better than it was.

The BSR changer appears to need the idler/drive wheel surface sanded lightly to remove glaze. It does not want to go completely through a change cycle when cold without some assistance. The change cycle gear has already been removed, cleaned and relubricated. That made a significant difference in the ability of the changer to work properly. The motor shaft spins freely, so that is not the source of the problem. The turntable has been cleaned and relubricated too, so it is eliminated as a problem source too.

More later.
