Philco 84 Open Field Coil
#1

I was given a rather nice Model 84 by a co-worker about a year ago.  In the process of checking it out, I found it has an open Field Coil.  After procrastinating for a while, I've decided to attempt to repair the break.  The image below shows the field coil mounted on the speaker.  I have a couple of questions before I start.

1) The arrow in the picture points to what appears to be a paper 'band' that wraps around the outside of the coil.  What was the purpose for this wrap?  Was this there to provide strain relief for the solder joint that joins the rather large wire, with the small field coil wire?

2) Assuming that the paper band was for strain relief, any thoughts on how to put another band around the connections when I'm done repairing the coil and/or the connections? Ideas on what to use to do this?

3) One of the two connections to the coil is at the top of the coil as seen in the image.  The other is buried beneath the big "U" bracket that holds the coil to the speaker frame, roughly 90 degrees clockwise from the one you can see.  The connection at the top looks to be rather easily accessible, and I'm hoping that the break is there.  If that turns out not to be the case, any ideas on how to get to the other connection?

4) Any general ideas on things to remember to do, or not to do, as I'm doing this?

   

Thanks,
Jon
