I've noticed that when I play a cylinder, it starts out sounding great. However, the sound begins to degrade as it progresses, until it sounds little better than noise by the end. I have played a good number of records once I noticed this, and it is doing it with all of them. Once the record is 3/4 through, it is virtually unintelligible. Any ideas on what could be causing this and how to correct this? Thanks!
It sounds to me like the stylus might be worn. In a similar way that a modern stylus can start sounding aweful when it picks up too much dust, a worn stylus can be cutting the wax & building up on the stylus too. After playing a record, gently wipe the stylus with your finger & check for any black dust. If there is, you may have to turn the stylus or get a new one. Also, if the stylus & weight aren't moving freely, it could cause sound problems too.
