I did not, but I sure will. I guess that would never have occurred to me, but it makes total sense. Thank you, sir.

I replied to this post, but it wound up posting somewhere else. Still don't have all this fancy-dancy forum stuff figured out. I have not cleaned the input contacts, but I certainly will try that. After 50 yrs., it could probably use it. Thanks for the suggestion. That probably would not have occurred to me.
