C91 is in the hv reg line, so I'm not sure what 130pf cap you mean cause there is none in the area.

IF the 6BK4A failed, it could shunt too much voltage to the cap and toast the cathode resistor and cap there, what kind of cap was it?

It may have just been bad/ weak, DO make sure that what ever you replace it with is rated at 1kv or more, and that all other parts in the area are OK and that V17 is not toast.

Remember, when you adjust G1, or brightness, the shunt regulator V17 works to keep the HV stable, so something weird happened here in the area.
