I just purchased an Edisonic Schubert, and I have a question for the group. I have been reading hear and there (not just on this site) that it is practically a given that the gaskets need to be changed on the reproducer. Being new to the world of Edison, how does one really tell if the gaskets are shot? This reproducer plays very loud and seems to handle most tone frequencies well. I will occasionally hear what sounds like the tone fracturing on really loud, higher frequencies, but it is hard to tell if it is the record or the reproducer.
I have no idea if the reproducer has ever been rebuilt (I don't think so). It looks like the diamond may have been changed, as it looks like it is soldered in place (and not a fantastic job of it either). I am just trying to determine what it might need to be playing at peak capacity. Your thoughts are appreciated.

You can be reasonably sure the old gaskets need replacing. They are cheap.. Ebay has a good set that runs most of the time..
If after you get the gaskets the problems with the original diaphragm continue you might consider a new diaphragm..

"Reasonably sure" is a good way to put it: meaning that one should not assume a rebuild is necessary in ALL cases. I recently bought an LU-37 (London Upright) with its original standard reproducer in place--and I will not touch it as it has the best sound of ANY Edison reproducer I have heard. Ultimately, one has to subject these reproducers to personally tone tests--and sometimes resist the urge to send them off for a rebuild as sometimes you will find that the original diaphragm and gaskets have held up remarkably well and should NOT be touched.

I use a crude but effective check - gently suck the end of the reproducer. If it holds the vacuum, the gaskets are ok and on the maxim of "If it ain't broke, don't fix it" you can happily use the reproducer right away. If not, they are gone and need replacing. The procedure tastes disgusting, but works.
Having said that I have found all sorts of odd rubbish in reproducer which have not been cleaned for years, and being a compulsive fiddler I tend to clean newly acquired reproducers and routinely replace the gaskets. They do go hard, which doesn't enhance the sound, and always sound better after I have 'fixed' them. Well, almost always...
Cheers
