Inner groove "Rumble"


All of a sudden, I'm hearing a weird "rumbling" once the stylus reaches the last inch or so of a record. There has been no sudden "trauma" to my table or tonearm. The first 80 % of each LP side still sounds absolutely fine. Any thoughts as to what's happening here ?

Adam, Have you checked your turntable bearing? Now that your rumble is generalized, I am guessing you have either run out of lubrication in your bearing and/or your bearing is worn in some other bad way.
Dear Adam18: Seems to me as a cartridge suspension or a tonearm bearing problem.

It's dificult to say for sure so all we here can only speculate about.

regards and enjoy the music,

Raul, How can you rule out the most obvious (to me) possibility that the platter bearing is worn or low on lubricant? He most lately said that the rumble is audible at all points across an LP. But he has lost interest, and so therefore have I.
Dear Lewm: Well, that already posted by other persons and I think he needs all the possible " reasons "/speculations.

Regards and enjoy the music,
R.
