One thing you might be able to do to kill it quickly is if you have a damaged HV meter that no longer works, you could use the biggest resistor from it as an HV bleeder. There were electronics mags back then that had spot suppressor articles with gun bias spot suppressor circuits.
I have a 1960 Zenith where the spot burned it's self into the phosphor, and I ended up swapping the CRT.
