Does anyone make acceptable replacement diaphragms? I was thinking of bidding on it.

I occasionally make diaphragms of the correct Aluminium grade and thickness

At least the starting price is now a more realistic reflection of it's condition.
As well as being back to front, the diaphragm appears to be corroded and may need replacing.

Wow - time flies very fast indeed.

I may well be wrong, but I assume that Expert sound-boxes are rarer than EMG sound-boxes ?

I think this because I see fewer Expert ones and Expert was a later 'off-shoot' from EMG and so were produced for fewer years ?

Also, I seem to remember that on this forum some-one once said that they prefer the Expert (or was it EMG ?) two spring sound-boxes to the 4 spring versions. I can't remember when or where this was said.

When it came to me it had an 2-spring EMG "Horseshoe" in the original box with instructions. Frank James and other authorities told me that this was a better soundbox than the 2-spring Expert, and after Ian Maxted rebuilt it for me the sound quality was and still is superb. Watching Ian work his magic, I felt that I was in the presence of a master.
In the interests of originality I also use a "New Old Stock" Meltrope III which runs the EMG pretty close.
