hello another new guy here. i just joined this forum as i have just picked up my first edison mach. a c-150 for $40 bucks unfortunately it has issues. motor and reproducer issues. first i need some help on what to do about the reproducer. i started collecting phonographs about a year ago and this being my first edison i don't know much about them. putting aside the condition of the stylus which i think needs replacing as when you look at it with a mag. glass the tip looks like a ball point pen. can anyone tell from the picture if the diaphram is still usable i know i will have to replace the gaskets. can the link be replaced or do i need a new diaphram. i also know the limit pin is missing as well as the steel piece that pivots is broken. is this something that MR. HANDY can fix or send it away. any help on this matter would be greatly appreciated. i know my other option is to try and find a good usable one and that is something i'm looking into but in the meanwhile i would like to get this one working. by the way awesome forum. thank you dan Attachments:

Hi Dan,
Your Reproducer is the earlier type that had the separate stylus bar plate screwed to the weight. This was phased out by about 1916 for cost measures no doubt and the stanchions that held the stylus were cast into the weight. The limit pin was actually threaded and screwed into the weight on these early Reproducers and are quite easily sheared off, in my experience. The later pins were much simpler and press fit into a drilled hole at the end of the weight. As I am a machinist, I made up a bunch of these years ago to use as replacements for repairs but I no longer have any more and don't have any immediate plans of making any more. I now just drill out the remains of the old threaded limit pin and replace it with one that is similar to the later style pins. You can get different types of replacement diaphragms, ranging from treated cardboard with a dental floss type of linkage to ones that are more like the original rice paper type. One of our members here, LarryH also makes a very acceptable diaphragm. Your will definitely need new gaskets as well. If you wish for me to repair your Reproducer, you may contact me off list.

Bill, I have a question, I have a C-19 DD Player, and I need to know what a "good" condition stylus should look like versus a stylus that should not be played and will ruin records. I am really confused on this one. A pic of a mint stylus would be great. Should the tip come to a "V" point, or is any flatness of the tip allowed like in the early wax cylinder players that have like a "ball" tip.. I would appreciate all of your insight. Thanks, Tony Kovar, Melbourne, FL.

Hi Tony,
If you have a 10x loupe, you can usually see if the diamond stylus is badly chipped, but it is difficult to see a bad stylus with the naked eye. One of the typical ways to test a stylus is to let it down in the runoff area between the last of the groove and the label. If it is chipped, it will usually penetrate the condensite layer on top and expose the china clay core below presenting a brownish groove. Worn but non chipped diamond styli can cause an echo effect, especially in spoken records and under extreme magnification will have a flat spot worn into the diamond. The diamond tip on an Edison DD Reproducer is polished to a point, approx. .002, and much finer than the sapphire stylus found on a 2M Reproducer. If you are concerned about the condition of you stylus, you can try the method I explained above and look at the results. I have had many DD machines pass through my hands over the years and have found that the styli are usually sound enough to play your Records w/o any damage, but is always a good idea to test the tip prior to playing any expensive DDs you may own.
Bill
