Ah-ha, I missed this the first time I read your response:
“At least on my 301, the platter will not spin freely-the idler wheel-mine is the Audiosliente btw-is always engaged against the inside platter rim. ”
This is the culprit! I don’t know if the unit has a fault or if someone purposely disabled some of the linkages but I would say this is a sure fire way to create a flat spot on your idler wheels rubber periphery and hence noise in the form of rumble.
I can tell you with confidence that this is not the way the 301 or 401 was designed to behave.
