A follow up post to the problem I described. I received several replies offering solutions since the post went live. One of them, from Mr Quek, a genius in my opinion, suggested I plug the board back and try again. He seemed to be confident of some loose connections causing the problem. I did try to fiddle around with the connectors the night I dismantled the circuit board. But you know what? He is right!!! That confirmed that he is indeed a genius! Thank you, Mr Quek!

Wong, after over fifty years working in electronics I wish I had a nickel for every board or component that was 'bad' when removed and worked when plugged back in. When stationed on Guam the tubes in the multi-couplers would 'fail' after 3 months. I started checking the failed tubes and they were ok. So we started just pulling them out of the socket and plugging them back in.It was a problem because there were hundreds of tubes in them, quite costly to replace every three months in stead of 18 months the normal life of vacuum tubes. Your comment will be posted after it is approved.
