Wanted: HMV/Victor No.4 Diaphragm and Gasket

Post by kirtley2012 »

I've got a brass HMV No.4 soundbox which had the worst case of hardened gaskets I'd seen and the diaphragm is separating and shot, anyone have spares?

Cheers

Forum member Soundgen sells mica diaphragms in various diameters, and good results can be obtained by replacing the one piece gasket with soft rubber tubing either side. This is also available from some eBay sellers.
