Yamaha GT-2000 from Japan or local TD-125?

I don't cite one case, I have had experience of more than one Platter Spindle Bearing with a very noticeable sideways movement.

In conjunction with my own experiences I personally know others who have encountered it as well.

My own interest has prompted me to look further and there are plenty of cases discussed on the internet.

What is not so common is the most recent methodology I have adopted to be the corrective measure.

The interest has lead onto other corrective measures to be developed and on the table to be put in place.

Can you be more specific?

Dear @brecchi  : I gave you as an GT 2000 owner a gentleman that is not, my mistake.

You need to contact with @theophile  that's a way experienced owner of the Yamaha GT 2000 and he is an Agoner.

Do it you a favor and wait to see if he chime here on what you need to know.

It is not always the sideways movement that is discovered, as stated on previous occasions. When taking the Bearing Assembly apart, the Ball at the Thrust Interface, usually discovered to be a loose fit, or interference fit in the base of the Platter Spindle are on occasion found to be damaged with a Spalling and even worse a Scribing on the Ball Surface.

Either one of these being present is an indicator for Metal Particulate being free to migrate and is now included in the surfaces where there are interfaces between Sacrificial and Non-Sacrificial Materials.

Such an environment has the capability to cause unwanted damage to the non-sacrificial material.

It is an even worse condition when the housing is arid dry in relation to lubricant, loose and migrating metal particulate damage in this type of environment will need substantial skills to correct the damages being witnessed.

Again, it is each to their own, if the want of an individual is to use a $2K to $5K Cart' on TT, knowing it has such a condition, or potentially has such a condition, then that for me is just fine.     

Suffice to say that sideways movement, manifesting as platter wobble or run-out would be unusual in a high quality vintage DD turntable. No one doubts that the bearing of such a TT should be evaluated for excessive wear and serviced after purchase. I have had six higher end DD TTs, four of which are up and running in my systems (two Technics SP10 Mk2, one Mk3, one Denon DP80, one Victor TT101, and one Kenwood L07D). I’ve not seen a problem with bearings that required machining or replacing the entire structure. In nearly all cases, I have had to clean the bearing well and replace the lubricant, but no bearing assembly was bone dry upon receipt. Guess I am lucky. For me, the most common problem with a vintage DD TT is electronic in nature. Both my DP80 and my TT101 were acting funky when I bought them, but the late great Bill Thalmann fixed the DP80, once I found the necessary integrated circuit on line, and JP Jones fixed my TT101. I think my DP80 was run on 120V by its previous owner, when it wants 100V. That was not good for it.
