HP 54845A Oscilloscope A/D Hybrid Cleaning

I repaired a 54845A oscilloscope (well I got it to boot, and then got rid of the self-test & calibration errors) and I wanted to share a specific part fo the video.

I couldn't find anywhere on the web someone showing what they did to clean the A/D Hybrids on the scopes acquisition board. I was failing the FISO self test and vertical calibration till I did this cleaning.

Now the scope is passing those items and working well.

The excellent teardown/repair on "The Signal Path" is here:
