[Phono-L] Patching Pot Metal Reproducer

[Ron L'Herault]

John,

Is the diaphragm the same size as in other common reproducers?  APSCO or
George Vollema would then have them.

I suppose someone could have hard soldered the nut on.  You need a small
torch to melt it.  I can try it at the lab if you want to come over.

Gents,

I'm attempting to rebuilt a generic sound-box from a Berg Artone portable
phonograph. The potmetal shell parts are still solid but showing numerous
cracks and the supports for the needle-bar have cracks dangerously close to
the screw holes. I had planned on filling the cracks with JB Weld, any
opinions, ideas? I need a flat rubber gasket material as well, any ideas
where I could locate such a beast? Finally I was unable to melt the solder
holding the needle-bar to the diaphagm, which appears to be copper or
copper-plated, it seems to be a lump of solder holding a small nut in place
to the front of the diaphragm. The needle-bar appears to unscrew from the
diaphragm, an earlier repair possibly? Any tips would be most appreciated.


Regards,

John B.
