Sorry, I've just remembered that there is one component of my Garrard that has deteriorated - the original rubber mat! It is a bit frayed round the spindle hole. A mat is needed to control resonances in the heavy aluminium platter in my opinion.
I replaced it with The Funk Firm's Achromat platter mat.
Since buying what is left of Garrard's turntable business, SME has spent a lot of effort replicating the original rubber mat. Frustratingly, they will only sell it in conjunction with their NOS units, which list for 10s of thousands. I don't think they plan to sell more than 2 of these a month.
