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 ?

"But, as summer approaches.... a lot more time with golf, bike riding, hiking with my dog, and all kinds of outdoors stuff ..... and a lot less time sitting in my basement music room !"

Are you crazy??? LOL!
Adam, Your dog will probably like it more if you sit with him inside in an air conditioned room and listen to music, rather than taking him on a hike. Just take him out once a day for a romp and a poop. Dogs don't need the exercise
