I really prefer to avoid using any weight at all if possible, it can only add stress and possible wear to a bearing assembly that was maybe not designed for much extra weight than the platter.
Record weight for Garrard 301
I've long thought a record weight would be beneficial on my 301 but worried about a record weight deforming the flatness of an LP by pressing the record's center into the underlying dish of my 301's original platter. Should I be concerned? Perhaps this is an insignificant worry?
