John, I had tried nearly everything with that machine including rewiring the baffles, taking baffles in and out of the circuit, using different capacitance capacitors all the way from 5 to 12 uP. I hadn't gotten to the point of soldering yet, although I had replaced most of the brass connectors on the electronic control.
It seemed as though everytime there was a major shift in humidity everything that was in perfect balance before would go out AGAIN. Last summer I had it working perfectly on just one baffle. Then as winter came on, I ended up adding the other two baffles back in to get the dryness right. As it got warmer and more humid in the basement it started overdrying again. The thought doing a biennial addition and removal of baffle circuits through the burner access door was less than appealing. I grew weary. I still have all of the parts in a shoebox that will be lovingly stored marked "1967 DG806 electronic control"
