Hi there, I'm a cdx lover user for quite some time now. With some friends we tried to mod this player for couple of years. Trying to improve, or get rid of the platter fluctuation.. -easy mechanical fix shown here: https://www.youtube.com/watch?v=P7Aiet-T-Vs&t=5s I own 5 pairs *(I think) of cdx and are happy to help with any tests or modifications. We tried to make the cdx work as a serato dj controller, making the platter scratch encoder work for mp3 play to work with serato timecode.. It would cut off the use of display and some functions of the cdx only left witk working platter, pitch, and play stop buttons Now seen this thread - this is what we wanted to achieve but due to less and less free time.. we spent 3 years debating about it and nothing worth came out of it. So we would like to contribute. My friends also have some big electronic knowledge, and have some "laboratory" equipment to use for this project. Not to say some over the average skills in electronics. Waiting for some good news Cheers
