Would anyone be willing to work on cap replacement on Mac Plus analog boards? If not I may just have to teach myself how to fix these things and start a service of my own. I love my Mac Plus when I can get video out of it.

If you're getting intermittent video out of your Mac Plus, check/resolder pin 1 on analog board end of the cable which connects the logic board to the analog board. That cable carries the video signal and that solder joint is notorious for failing.

The typical symptom is a Mac whose video goes to a single dot in the center of the screen and a whack to the left side of the Mac restores video.
