I had to put this aside due to other things but during that time I kept working on other electronics and have really learned a lot. I had been over that scope with a fine tooth comb, I checked every component. I needed a break. This scope like most 465s have been sitting. I had tried cleaning the contacts with automotive MAF cleaner previous to all this, all I had on hand that seemed reasonable. The problem was corrosion in the switches. I finally broke down and bought a can of DeoxIT D5. This fixed the traces corners. I didnt even need a calibrator to adjust them after that. Although I now own a working cal pak. WooHoo!
I have this theme going where when sometimes I fix something, something else breaks. My Beam Finder switch was damaged so I replaced it with a donor. Now my traces are flickering intensity badly. not sure if its related. Off to troubleshoot...
