Classic Platter Bearing stainless steel retaining "donut".

How does one go about purchasing a stainless steel Classic platter bearing threaded retaining donut? I enquired with my dealer, but he does not know what I am talking about. I have attached a picture for reference.

Me too! I have the original Classic that had the steel nut to secure the bearing. I have since replaced it with the delrin nut a few years ago but never knew about this latest one. If Harry or Mat can also describe the sonic difference this would bring would be greatly appreciated.

We tried supplying that on the Classic 3 but that "nut" is really expensive to make and would have caused a price increase. We can make some if you want them, they look really great, let me know how many we need and if you have a screw in the middle or the entire thing is threaded and spins on.

I'm in for sure. My bearing is threaded all the way and has a centre tapped screw bolt in the bearing housing bottom.

Hi Harry ,

Thanks for the reply. I will take a picture of my bearing . Mine uses the Delrin Nut and has a threaded hole in the tip were I attached a lug in order to secure a ground wire to prevent static build up in the platter. By the way Harry in this stainless donut is there a part in the nut were one can attach a ground wire?

Yes, if you can tap a ground screw on the bottom (just like the old TNT Mk5 donut) that would be awesome.

I have attached a picture of the ground screw donut and a picture of my Classic bearing retaining nut

Hi Harry,

I attached a pic of my bearing with the original steel nut and the replacement delrin one. This thread is bringing up more questions. Is that hole at the bottom of the bearing meant for a screw to ground the platter? The hole does not seem to be threaded. I purchased my table mid 2009 and I believe is one of the first production versions. Let me know if my table would benefit from this 'donut' upgrade.

fyi The large washer under the bearing flange came from the bottom of the table. When I replaced the motor cover from the ring to the black full cover it was not clearing the bottom of the platter. I moved the washer from the bottom to the top and all was well.

Once this Christmas rush is over I will make a bunch of large polished aluminum bell washers, the really nice looking ones, with a grounding screw in the bottom and you can change yours for it at mfg. cost, no profit involved.

Keep pressing for it and it will get made in January.
