Here's an update.

Macdrone sent me a new analog board. He tested it in his machine and it boots. Unfortunately, it doesn't work in mine. It's actually worse.

I was able to eliminate the horizontal lines by adjusting the brightness knob, but the display is seriously warped and there's a lot of scattered noisy pixels. The warping moves down the display.

I tried adjusting the pot on the board to 12 and 5V, but it won't go that high. It maxes out at a little over 11 and 4 volts.

I'm already in the hole $30 for the caps and the board. I think I'll chalk this one up as a loss since I think it's a combination of the two boards not working. At this point, it might be easier (cheaper) to just keep my eye out for a new machine all together. Maybe finally get a Classic II or an SE/30.
