Ok, I opened the tester up deox'd it and in the process discovered that the 80 tube inside the tester had a loose piece of solid "silver" wire floating around inside the tube. I replaced it with one of the 80's I was originally trying to test. Same results. I jiggled the tube being tested and found that the socket must have a loose connection. By jiggling the tube, I was able to get a reading. Ok, I then noticed in the tube being tested that there are these white strips of material loose inside the tube. They have obviously flaked off of something inside the tube. The tube is well mirrored, still, and tests good. Anyone have an idea what these white "strips" could be? Thanks.
