In addition to bumblebees, I think I see some "maroon drop" caps in there. They are brownish or maroon and look like modern orange drops except for the color.
Those are also candidates for replacement. My RCA CTC-7 had terrible sweep problems and other issues before I replaced them. It magically made a fine picture after all of the maroon drops had gone bye-bye.
Ditto, even more so, for any remaining paper caps. If the values are printed on the cases, you don't need a schematic to replace those. If you want this TV to work reliably for an audience, I would not even waste time testing those.
