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 ?

if it's not time for stylus replacement, than it's probably your phonostage needs service.
Did you try cleaning your stylus? It could be the result of vinyl residue built up on the stylus.
