P-309ff EDISON Diaphragm for AMBEROLA Reproducer

P-309ff EDISON Diaphragm for AMBEROLA Reproducer. Reinforced design of recent manufacture. Works like new. Price is for one diaphragm with the cord linkage. In the photo light and reflections make the diaphragm look darker than it really is. [When replacing the diaphragm, you should also replace the gaskets, one on each side of the diaphragm. Gaskets are NOT included in this sale. The gaskets are available at P-385A and P-309ee.]
