Was the bearing replaced with the Sub-platter? Or, are you using the original?
There is quite a choice of bearings out there too that will make a difference.
Relatively cheap! Isokenik sells a ruby.
I see Michael is offering a "Silicone" Belt now ($20).
My Double Pulley was shipped on 6/2 still waiting.
After this is done, I'm done ! Famous last words.
This P5 will basically be a P7 without the special platter, maybe better?
Man, I like these Arms>
