Elizabeth,

The problem might be that you are playing a new vinyl recording on an older turntable. Just like CD's the older ones have some differences. Try one of the newer turntable
consoles, even if you have to take the vinyl to the store for a try out before you buy the machine. PS. If the turntable only has two speeds 33 and 45 it is "newer". LOL
All of mine still have 33/45/and 78!!!!
