If not that clean & tighten module connections.

Thanks, I will give it a try. I spent some time touching up convergence and am very impressed with the vertical sharpness. I can’t believe Zenith’s CRTs had a focus this sharp. The horizontal sharpness needs work though as can be seen from the grid test pattern where the dots at the center of the grids have streaking to the right. Even if chroma gain is set to black and white, the streaking persists. I know Zenith used electrolytic capacitors to AC couple the video signal path. So I will try replacing those with polypropylene film capacitors. Any other idea what to check for this streaking?
