I take it off while playing. Simply because the hinges broke a couple of decades ago so it is either on/covered or completely removed. I do not put it back on while playing not to accidentally make some damage while positioning. It comes close to the weight, etc.
Ok guys
My question is this, nothing major, more of a curiosity. When playing an album does it make a difference if you leave the dust cover up or down? Probably stupid question but hey there are lots of opinions out there
