Thank you for that insight around speed fluctuations, phoenixengr!
In the later 90's, I had a full blown SOTA Star Sapphire with vacuum hold-down / electronic flywheel (line conditioner) - paired with a Fidelity Research fx64 arm with mid-priced Grados. The speed would hold only through a 3-4 hour listening session no matter what I tried, including swapping out for a new motor with an engineer friend. In the end, I simply lived with the issue. Two decades later, it's still comforting to know that something can be done.
During that experience, my rig was situated on a jouncy upstairs room, presenting a real challenge in isolating the turntable from footfalls, etc. I tried bladders, masonry (never have had any luck with that,) tiptoes, sorbothane, etc...but, the "cure" in that application was a sandbox with super dry play-sand from hardware store and a carefully leveled maple plinth atop the sand under the SOTA. Maybe this may help others.
Happy listening and More Peace, Pinthrift
