Re: 1938 Murphy A56V television restoration
One trick I discovered for restoring very old speakers, often the paper has dried out and become quite brittle. If that has happened it is possible to rejuvenate it by using a solution of 3 or 4 parts of mineral turpentine to 1 part of Linseed oil. It is gently brushed on with a very soft brush (like a makeup brush). After a day the turps evaporates leaving the small amount of linseed oil in evenly dispersed in the paper.
