Hi GUNRUNNERJOHN,
Thanks for the pictures. I tried the pot adjustment but there was no change. I was hoping to find the pot turned all the way in one direction or the other, but it was right in the middle with no change in either direction. I will be in the Bay Area late next week and am lucky enough to be able to drop by the plant in Santa Clara to have them take a look at all three boards to see where the problem is.
