Well, the yoke would not clear the socket no matter what. I carefully took it apart (about two hours of work) and saved the coils for replacements. I couldn't get the yoke while on the tube in the chassis because it is installed from the rear and the tube from the front.
Anyway, it works again! I still have to find out why the focus is at the end of the range (either too much or too little current thru the focus coil). The picture is clear and bright. The tube woke up faster than I ever expected. Pictures tomorrow!
