Not that I know if. They’ve been doing it the same way for ever. I don’t have a Rega deck, but mine uses the same system but with two motors. These are Rega belts, the $15 upgrade versions. They developed new belt material for the P10, but you can’t buy them as replacements (yet). Given the choice now, money no object, I’d get a P10, or two P10’s as my deck has two arms.
This is the P10 bearing. It’s a work of art and incredibly good for the cost of the unit.
The P10 has this bearing in a brass housing sitting in an aluminium plinth. All manufactured to extreme tolerances. My turntable is made the same way, to tolerances of about 10 microns.
I know how expensive my turntable costs to make as I know the designer and they have their own CNC equipment that cost $millions. Given their quality, the P8 and particularly the P10 seem incredible value for money. I think the reason is that they are made in such large quantities.
This is the bearing from my deck, and the housing. Same idea but slightly different design, but my deck has a 10kg platter whereas the Rega is probably only 1-2kg.
