Micro Seiki RY-5500 motor noise repair pdf

Dear Steve: Yes you are right. The Rx 5000 has no isolation and we need to take care about.

I never hear a MS 5000 on a spring isolation system but there is no reason why does not works fine.
Till today I don't know the perfect TT isolation because this subject has many interactions overall and some isolation systems are very good in some " areas " and other systems in other areas.

Yes, I know that certainly there are better isolation ways than the AT-616 but these ones works for me and I never have the opportunity to test a different one in my system.

Regards and enjoy the music.
Raul.

Another quick note on RY-5500 noise: I recently received an e-mail that described a subtle "clicking" noise emanating from the RY-5500 when under various thread or belt tensions. I noticed this too from day one of ownership and thought it might be normal. When the major noise occurred and I fixed it as described in my article, I noticed this clicking also went away! I can only suspect that sound is abnormal, too. The good news is it is possible to have a completely silent RY-5500.

Dear Kipdent,

Great process. Quick question, does the RY-5500 motor have an air bearing for isolation?

Thanks,

Simon

Simon--

The RY-5500 is the *drive motor* for the RX-5000 turntable (as well as many other models). The famed Micro Seiki "air bearing" that you may be referring to was for the platter on the plinth, and found only on some of their very top-line models. The bearing in the motor, for which I describe a fix, is a straightforward DC motor with a traditional sintered bronze bushing.

Hello all, I am beginning to set up my RX/RY3000. Have a wall shelf (1.5m x .6m) and am debating whether to isolate the whole set up with one unit (eg a vibraplane or similar) OR isolate the motor and the platter base separately (eg by use footers etc. like Raul was suggesting). I was leaning towards the former but see in this thread and others that some people are using the latter OR are they doing both!

The feet on the motor base are solid solid brass pins and seem to me to have no isolating properties at all. Has anybodyt replaced theirs or do they resort to the above isolation measures.
