Edisonic gaskets

[coyote]

I've taken apart a ton of DD reproducers and a few dance reproducers, but this was my first Edisonic. The original gaskets look almost like they were cork, but have the paper liners and were as brittle as original "rubber" gaskets, but they looked different, maybe rubberized cloth? Did Edison use different gaskets in the Edisonic reproducers, or are these just so dried up they LOOK like cork?

Btw, it sounded great even with these gaskets, although it needed a new stylus as the old one was leaving marks during the "dead wax" test. I swapped a Dance stylus as I didn't feel like soldering on a new hook for the spring.

Also along these lines, adding to the question of the best diaphragm, after comparing original and Bogantz diaphragms in a number of DD repros, I have to say I much prefer the originals. My apologies to Greg.

I've come across these cork gaskets in a standard reproducer on a very late L35 too, so they were probably changed late in the game as a cost reduction more than anything else knowing Edison
I'm not sure if they were actually cork, but I think so.

I have run into a number of cork gasket sets in my day. In fact the Edisonic update that came with one of my machines also used the cork set. Most sets are rubber, but once in a while you see them, I don't know if they are original or latter replacements?

IIRC, the cork gaskets were standard '23 and later and were used for any factory replacements due to the instability of the rubber gaskets of the time. I think Steve Medved may have some input in this too.

Bill,

What gaskets did you use in the Edisonic that I got from you? It is by far the best sounding Edisonic I have ever heard - Rocky can attest to that as well I think!
