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.
