Assuming the rib on the cap is positive. I believe the cap was in backwards. Should be 100 uf @ 25v. I would go to 35v or 50v for a little more margin. Attached is more of that circuit, which is dynamic convergence and associated wiring, from Zenith CM-122, confirming that SAMS in that area is correct. In the SAMS picture, Cap positive, was oriented to the back of the chassis.

I don't pretend to understand dynamic convergence circuits but you could have impacted several coils and controls on the convergence board/clover. From your prior threads you have been working on that board. Did/do all of the controls work?

Do you have any pictures of the chassis from your prior recap?
Would it be possible for you to post the adjustment section of the CM-122? I want to see if it compares to the Sams, or if it has better/different procedures.
