Thanks for the (as I respond) 3 replies. Keep them coming PLEASE.
I really dont believe contact pressure is too great. I have tested incrementally and minutely by reducing it until platter speed is uneven AND platter continues to rotate long after motor stops (ie too light). All is level too. The whole thing is stood on one substantial and level Symposium Ultra base. Motor parallel to and symmetrical with the platter.
This squeak is in fact the tip of an unfortunate iceberg. Problems started before the rimdrive conversion. I see from other threads I was not alone in experiencing a loud Hummm. Even my unprompted wife commentated on it from 8 feet away ! when at 45rpm ( the deck, not her) 5 feet at 33rpm. After a long long story and lots of contact with VPI the Hummm disappeared (see later, it may help a fellow Hummer or two) but now Im still left with the squeak.
When belt drive was first converted to rimdrive I was still failing to solve the Hummm and hoped rimdrive would fix it. It didnt. I then had a Hummm and a squeak.
VPI shipped me a whole new (native, unconverted) rimdrive and motor assembly. You cant ask for more than that from a manufacturer. Unfortunately I soon found out that, indeed, I couldnt ask for more than that. Well, I could ask but I couldnt get.
Mysteriously, the replacement, unconverted rimdrive assembly made exactly the same squeak and was returned. Odds-wise, the finger of suspicion shifted elsewhere ( to ME for instance, if you are VPI).
Superplatter edge seems to be vertical, even and consistent as I watch the rotating edge through a magnifying glass with a lined background as reference. There is no apparent lateral or other movement. And anyway, the squeak is in sync with the rimdrive, not the platter.
Hence, Im still at a loss and will gratefully consider all suggestions other than advice to only play records by the Chipmunks.
As promised, I will return to the Hummm but think this response is long enough. Ill do the Hummm in another (I hope required) Response.
