It wouldn't surprise me if a foil/paper tubular cap in the vertical circuit shorted, causing overvoltage (ergo overcurrent) through the resistor.

Just a guess (Many other possibilities)

There is an electrolytic on the cathode of the vert output that
causes the bottom to pull up. Eventually the vert should be recapped
except for the discs. Also the 3 legged integrators changed.
Check all resistors especially high ohms ones. Do recapping
one at a time then test to be sure of no mistakes.
These will be of interest........
