Thanks Ron and BDM, for your suggestions. Ron, even though I had "cleaned" the band selector switch with a quality contact cleaner/lubricant, I still did more of what you suggested. You have much more experience than I with this. I used a different kind of cleaner and the a toothbrush with a "haircut" (I had cut the bristles short so it would pass between very close switch wafers.), but with little or no improvement. I used a contact burnishing tool (I'm retired from the telephone company and we used this tool to burnish relay contacts.) with still no help. Still convinced that I was onto something, I "flexed" the movable rotary contact fingers on the third switch wafer and, "Voila!" Something happened! It turned out that the rivets connecting the front side contacts to the rear side contacts were intermittent and when flexed, contact was restored. There were movable tabs on both sides of the wafer, but they hod no electrical contact because they performed separate functions, but at times met the same switch contact finger. The solution was to solder a short wire from the front side to the rear side and now she "runs like a scalded dog," to use a typical NASCAR expression! Thanks to all who have scratched their heads on this problem and especially you who have responded. May God bless your day!
