Some have speculated that they must have had the problem since they were new but that seems unlikely.

There was an exact reproduction made of the transformer and it had the same problem.

The transformer can be replaced with a solid state HV module but they are very expensive.

There's a thread on the problem here:

I think there was a more in depth thread on the subject but I can't find it.

And a page on making the SS replacement: http://www.myvintagetv.com/philco_hv.htm

Google the model number and you'll find more on the subject.
Has anyone tried adapting a surplus Motorola electostat coil and circuit to these sets.
