Well IMO life does not revolve around parasitics. 
In your case I would start thinking about crispy critters across the AC
or HV and/or a moisture induced problem from non use. 
Unplug the tubes and try again, preferably with a variac or by rewiring
for 240 but plugging into a 120V line. 
Carefully look for carbon tracks on all HV components to ground. 

Im not saying that a parasitic could not be the cause but I would
eliminate all of the more common faults first.
