a few things

Zeniths used good caps, the only ones that may give trouble would be any bumble bees that may be there (maybe one across the line). Mass replacement is not advised. If you see any single electros esp if they are black with red paint, they can cause trouble. The cans typically are fine, esp if you did a soft start up. ONLY deal with parts that are suspect when you have a working set. Mass preventive replacement of caps on a nearly working set is not the way to go.

for vert issues, look for drifted resistors in the boost supply to the vert height pot and the feedback resistor from the cathode of the vert out back to the multivibrator.

check the electrolytic used for bypass in the vert out cathode.

replace the .1 elemenco (white ceramic if still there) that is used to filter the boost supply that is used after the height pot. Use a 2kv cap get them from mouser.

check the cathode resistor used in the vert out, 4700 1 watt.

Lin defects can be height defects that are trying to be compensated for by adjusting the Lin control too much.
