Title: RME-69 volume control Post by: N9AXl on July 19, 2020, 11:00:58 AM I am restoring this RME-69.The volume control appears actuated by a long rod which also actuated a NC relay which I assume is a T/R switch. The rod I have doesn’t appear to fit the volume control. The end of the rod is a hole bisected by a brass flange. Does anyone understand how this works? Is NC or normally open the position for volume? Right now the radio is completely dead but I did replace the PS caps and tubes. Powers up but no sound.
