Yes, a dead 555 (56?) would be a much happier situation, but --

You could take it to a local TV repair shop.  I'm not sure, but weren't PET 
monitors modified Zenith TVs?  A 70's Zenith TV would be right up their 
alley -- the guy working there probably cut his teeth on the family console 
as a teenager :) .

You have a schematic?  BONUS!  Take it along to the shop :) .

BTW, that 10 kV comes out of one of those voltage multipliers mentioned here 
lately.  Odd coincidence.
