Good question. I think you're listening to vinyl records.
I have not forgotten about it. I test solutions individually. I will solve the problem anti skating in the future. I have not designed it yet. Currently, I made a unipivot . I'm testing a technical solution now. It is a combination of a unipivot with a classic arm suspension. I do not know if this system was used somewhere before.
