SUCCESS:--I was able to remove the three pins holding the field coil frame to the speaker shell. Then I was able to use an automobile gear puller to remove the field coil pin (see photos).
Now I need to find someone to rewind the field coil with about a pound of 36 Ga wire and I can move on to the next step.
I'm not sure how I'll get the pin press fit back in place yet but one step at a time.
Thanks for all the photos and suggestions.
Mark

Those are details better left to the ones who know. Maybe you disconnected the wrong end of the wire.RodB — 06:22 PM
