Thanks for the reply Ron. Yes, the 4.7 is new and connected to the bottom side of the control to ground. So, my volume control is OK then. One thing I did find is that the 33K resistor #54 in the Sams print, was connected as shown in the Riders for the run 121 chassis, at the tap. The Sams shows it connected to the bottom side of the control.

I removed the tap connection for the resistor and placed it on the bottom of the control but it still squeals. If I keep the current draw below 460ma I can get normal audio from the radio, albeit very low, which one would expect.
