This evening I reinstalled the yoke and CRT wiring. When hooking up the yellow CRT wire to a terminal strip, I found this. First off you know that I clean off all excess solder and old component leads. Then install the wiring and components. After cleaning off the terminal, I had what looked like a small ball of solder left. I tried to pry it loose, but that didn't work. Upon real close inspection, I saw that it was a clipped off lead soldered to the lower portion of the lug! I used some solder wick to free it from the lug. It was very close to the chassis, very close. I don't know if that was there before I messed with it or not. In any case I'm glad I found it!
