Sota Cosmos restoration, or...

Another option might be to contact Steve Leung at VAS. He has done some bearing and thrust plate replacements (ceramic/sapphire) for other brands and may be able to help. He's also driving distance from you (right next to VPI in NJ).

Hi
I did write to Steve and he answered. But he said there must be a lot of wear on my table. I asked him what his charge would be to examine it. And I haven’t heard anything back.
 
Not so fast. I guess this was a temporary thing, just like before with the light oil. W/f is back to audible 0.2%. Was offered $650 for it. Thinking about it.

Did you ever soak the oilite bushings like MisterDK did? It seems like the motor is not the issue, especially since you swapped in a replacement, but rather the lubrication for the bearing as it maintained speed for a few days this time before having issues again. It would appear that could be the issue.

Soaking the bushings is very difficult in situ. MisterDK has his platter apart from what I remember. Mine is intact, so soaking the bushings will surely fill all the vacuum lines with oil. I don’t know his platter design, but on mine vacuum port is right next to the upper bushings. In any case, since there is a play in bushings, soaking them will not help. He uses heavy enough oil that it doesn’t leak out or evaporate. If I use this viscosity oil, my speed instability becomes horrendows. I heard from many people who use normal viscosity oil, and they have no problems. On the other hand, speed instability was noticed right away on the early sample of Cosmos in reviews. I can’t look at this thing anymore. I think I will take the offer. I’m not ready to pour $2400 into it, not even knowing if it will fix it. I’m in the wrong league.

Sorry to hear your purchase did not work out for you. Always a risk when buying used gear, and when buying 30 year old tables there is always the chance that repairs can become extensive. If this were not the case used gear would be priced 80 to 90% of new gear. I hope you recover the majority of your funds and the new owner enjoys the table after the restoration process.

Well I certainly gave it a good try! With your support )))
