You want to talk about foolishness, the damper and regulator had to be matched. I checked the schematic and noted that those tube heaters were connected in series, running off a center tapped 12 volt heater secondary. All the other tubes were run off one side or the other to ground. I just grounded the center point of the damper and the regulator. Problem solved!
