Don’t have, and don’t use a dust cover.
Will likely get one made for my TT to keep the dust off when not in use, but seeing as how it is used daily, it will be spending the bulk of its time stored near by.
Suspect if I get one made, it will be used if I go away for an extended time.
A friend of mine leaves his on all the time, which is easy as it is hinged. Opens it, puts a record on, closes it.
Seems to me, as the price of a TT goes up, the presence of a cover becomes a rare thing indeed. Especially one that is hinged. Can’t think of a single ultra high end TT that has a hinged cover? Would love to know if there are any?
