Micro Seiki RY-5500 motor noise repair pdf

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.

I did a few experiments with the RY-5500 motor
I used Sorbothane feet below it, but the Bass Performance was gone. Same with springs.
It is the result, that the Motor is nor REALLY stable, a touch of movement which was reflected via Belt to the Platter.There was a change in the Performance, but not to the better. I always went back to stock feet.
I use a Vibraplane below both units. The result is stunning.

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--

Are there more? :)

Syntax,
Am HS-80 just showed up on the auctions in Japan this week and went for about $1800. That's more than I have seen it go for, and I am sure one could build a new one (get a new one built) at a metalshop for a fair bit less.
