Micro Seiki RY-5500 motor noise repair pdf

Hey everyone--the Vinyl Engine kindly posted my repair instructions on their web site and it is easier to download it from there. I'm appreciative!

I am happy to hear this information is useful! I'll be posting some more experiences about things I've learned soon, including some stuff on the HS-80 High Speed Inertia unit flywheel. I feel a calling to get as much information as possible about these 'tables out into the ether. :-)

Yes, T-bone, I am xy.

Steve--

Thanks for your reply. I am beginning to learn that proper isolation is something I really need to explore for the Micro 'table, so any help you can provide would be very welcome!

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.

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.

Just a note to let everyone know I am extremely gratified the repair instructions were helpful, and I'm even happier it stimulated some discussion about the Micro Seiki turntables--something I'm quite hungry for!

I was lucky enough to find a Micro Seiki HS-80 High Inertia Unit flywheel (now shown on my Virtual System page) and it is an impressive upgrade, improving the bass and apparent size and stability of the soundstage (which was already pretty amazing). The discussion of what to use under the RY-5500 makes me think what I should use for the HS-80, too. This unit had no feet when it arrived, so I had custom ones made and they are beautiful! They work very well, but I do want to research isolation platforms more.

Thanks again to everyone--

Kip

Thanks, Trptplayer! Very kind of you.

Just a heads up--I am having the NOS aramid thread knot and installation instructions in Japanese translated and will post those soon. Fun stuff!
