Looking for some recommendation for purchase of permanent platter for Old Technis SL-D3. I have purchased a AT platter which is a soft material and stay's uneven when placed. Please help me with some recommedations.
if it is soft, it should fit the contours of the platter below.
if there is some underlying uneveness, even a solid mat will not help
if the platter mat is itself warped, return it for a new one
