Nude Turntable Project

Henry,
I suspect the coupling - 3 rubber grommets are the root of this evil. It won't matter how much mass or how stable the base is, if the coupling is inadequate.

Can't say I have a solution, but I'd try something like a thin bead of silicon caulk, or possibly the sealer they use to couple a speaker driver to a cabinet. I wonder what Mosin uses to couple Saskia to the slate plinth.

Regards,

Now that I see your last post, what you're describing is a low frequency oscillation (gets louder). If the stylus is stationary, does this originate in the table or preamp?

I went back to my original set-up from 2 years ago and guess what........
No feedback.....🎉😍
Then it dawned on me......
Has it dawned on you.....😜❓

Fascinating. A simple scientific inquiry. Well done `Ö´

Regards, Halcro: Intriguing. Echo chamber? If so, Dynamat or loose insulation might address the issue.

Peace,
