I was just looking at the schematic again. In the picture, the vertical linearity pot is a rather high wattage type. The 470 ohm resistor seems to make sense, even if the pot is turned to minimum resistance, there is still bias on the cathode. I also notice the 6K6 is triode connected. I would restore the circuit to original, per the schematic.
I find it strange, that some of the vertical circuitry is so far away from the sweep tubes. Rather complicated set to work on, plus the wiring is like a rat's nest.
