HP-82104A Card Reader Repair Questions

[matty_K]

Thank you for the reference to your notes. I had read the portion on repairing the pinch roller, but I hadn’t looked further to see the portions on waveforms.

Regarding the cover (and just to make sure I understand), how does one lift the rear of the cover to clear the lugs without having any surface to lever against? What is your preferred tool/method? One slip and you’ve bent the pins going up to the switch board or damaged the components just under the edge of the cover.
