Jan,
The isolation of the filaments will not prevent the damage caused by a CRT
when it arcs. As you know just because two transistors cross to the same NTE
does not mean that the two devices are equal. The original could have a
higher rating and be within the NTE's specifications. Try cleaning the CRT
to remove any loose flakes. The spark gap might be bad.
