Zenith Advanced System 3 picture tube testing

[Kevin Kuehn]

Finally today I got around to replacing 31 leaky capacitors, and it seems to have done wonders. Basically the picture looks very good to me, and no sign of those green retrace lines I recall seeing 12 years ago. The only very minor issue I see is some subtle shading down in the lower right corner. It's hardly noticeable unless there's a solid color on the screen, but then again sometimes it looks fine then too. I can see it best on the two b&w pictures below. I want to thank everyone for helping out with the suggestions on getting this set going.
