It is laquered copper !

Beyond that , Richard was very reluctant to tell me ! Top secret lol.

Hi Marco

There is no label recess , but the top is tapered down towards the centre , like the Oyaide mat ! And Richard recommends using a weight or clamp , again like the Oyaide , i can tell you my LP's sit very flat on this platter !

Just a little bit frustrated by the cartridge , you see it now has the top 550ML stylus and it won't come to life for some reason.
