I have also been restoring my 630TS and after the replacement of all the paper caps, all the electrolytics, and all resistors out of tolerance by more than 7% I recall seeing a similar (if not the same) image while using my little 5AXP4 test CRT. Unfortunately I did not take any pictures of that problem. Since then I have spent several days struggling with the video, audio, and tuner alignment. This is my first attempt at aligning a tuner, so I could be completely wrong. Most of my struggle was with the tuner alignment which ended up being solved by carefully selecting the 6J6 tube that worked best (alignment sweep response pattern wise) in each of the three tuner 6J6 positions. It went from only getting a weak picture and no sound of channel 3 on tuner channel 4 to getting a good picture and good sound of channel 3 on tuner channel 3 and channel 4 on tuner channel 4. I found that I had to perform the video and audio alignment again after the tuner alignment to get the video and sound right. The final video alignment was able to flatten the response curve, but not as good as the alignment figure in the procedure. Here is an picture after the final tuner and IF alignment. Its not well focused yet but I do not seen any smearing now. I still need to go over the horiz/vert linearity and size adjustments once the chassis is back in the cabinet.
