Need some opinions over JA Michell


I'm curious if adding more weight to the platter on my Orb would cause a deleterious result to the bearing. The springs are gone in favour of the True Point Audio suspension so the harm would not happen here but, the bearing I'm not so sure.

For example, I'm looking at two of three products from Amtrans in Japan: their turntable Sheet AMTS-03 1 kg  or their turntable Sheet AMTS-02 1.2 kg and the AMDS-01 Record Stabilizer 1 kg. The total added weight would be around two kg. 

Your thoughts on the matter will be appreciated. I have found no information over this very question.

Thrust Pads are typically the cheaper range of Thermoplastics materials where POM is the common selected material, but PEEK is the Thermoplastic material that most resists indentations from the Ball when additional weight is being added. 

I have seen an investigation on a TT many years passed, where such concerns are being addressed. The TT was used excessively used throughout one year, using POM. The Bearing Tear Down showed noticeable to the eye indentation when a Platter Weight has been more than doubled. In normal usage rotations it was suggested that the indentation would have taken much longer to manifiest.

OP

not ask due to warranty concerns? I could ask them to get their response for you.

The JA Michell Gyro is way over built , Im sure you could place a Abrams tank on top of the platter and it would spin fine. So I think the answer is no problem :-)  I would'nt hesitate.

Thanks to all who've offered their opinions so far. Yes, it is a tank and years ago, I began an undertaking to improve the performance of the table - changing out the trust bearing from steel to ceramic, from removing the springs, new arm boards, improving foot isolation and additional damping the motor housing to point out some mods. I've been using the Stack Audio Serene platter mat and stabilizer which in themselves are excellent but obviously from my question, I'm playing with further changes. Possibly my last.

Already have Ceramic Bearing,

You could find and order a few thrust plates, inspect every ____ months ...... that seems to be the only real concern.

Is it easy to change it? I changed my Thorens TD124 thrust plate once, it was old and that cast iron platter was over 9 lbs.
