OK, here's a seemingly strange replacement for the felt mat. I was doing an e-bay search on turntable mats for my P3/24 and I came across a guy who was selling an interesting looking mat, a sort of soft plastic mat that had an interesting pattern to it, like little interconnected squares. He was selling these for something like $20 each.As I studied the pictures I realized that I had seen this material before- in a dollar store! It was the same material that's used for table place mats.So I went to the dollar store, bought a place mat(for $2), used the platter from my TT as a pattern, and cut out a mat.And it worked really well, more and tighter bass and better overall definition. It made a noticeable improvement and you have a choice of colours. I continued to use this mat on my RP3 and only stopped when I upgraded to the GT acrylic platter which doesn't need a mat.
