Lisa AC interference coupling?

[sunder]

Sunder - I think this fix would be a useful thing to add to your FAQ on the subject, especially if blusnowkitty attempts it as well and it solves the problem for them. Compared to the recommended modification currently on the FAQ, it addresses the problem at its source in the PSU instead of accounting for it down the line on the video board (so the fix can be carried between systems), and it does not require the user fixing the Lisa to expose themselves to the high voltages and other dangers of the video circuitry and CRT. 

Yup, agreed.

My 2/10 has always had video artifacts... tearing between the scan lines. It changes as the horz phase is adjusted. I end up having to run the phase almost all the way to the left, and use the centering magnets to get the picture back in the middle of the CRT. The tearing changes depending on what is shown on the right most pixel.

I've not been able to figure out why. I've recapped both the video board and psu.
