Philco 90

Yes, it is quite a common problem and is harder to perform than the re-coning, especially in the 70/90 speakers that have pressed-in magnetic rod.
In a 20's speaker which is pretty much the same, the rod is held by a nut, and so it is in model H or G speakers.
Still, a field coil, even if easier to extract, uses lots of wire and many-many turns.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
