Hi everyone. I am reporting to you because you offered such good advice. I have found the problem and fixed it but I am embarrassed?to disclose that it was the relay. I had cleaned it thoroughly (I thought) but after eliminating everything else, an Elmer suggested that I revisit the relay. So after spending almost an hour gaining access, cleaning contacts again, and some minor adjustments, my TR-3 works and works well. Thank you all again.
