A while back I wrote about a nice Atwater-Kent 60 highboy I had purchased that worked well for a little while, and then the sound cut out. I pulled it out today to check things over one more time, still not getting an reading through two of the pins on the plug, but knowing the field coil was working, I decided to check the voice coil at the binding posts. Well, one of the voice coil wires was almost totally broken loose, hanging by one thin strand. Apparently whatever had cuased the small hole on the cone had also hit that wire and the vibrations from playing must have finally broken contact totally. Re-soldered it and now the radio plays again. Which is good because AK used way too much rubber wire and rubber shields under that chassis...   As long as I don't have to disturb it, everyone will be fine...

The kind of wire AK used is probably shedding the insulation every time the music plays . Or even now.
No special disturbance needed.
