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 ?

Marakanetz what would the phono preamp have to do with noise only on a consistent part of the record?

It sounds more like a stylus or tonearm problem, I had a similar problem with a rega 300/blackbird towards the end of the record. It would start mistracking about the same place you mentioned, my guess is it was the cartridge but I replaced the cartridge and the tonearm so I never really solved the problem.

Tracking at the end of the record is very difficult for a cartridge/tonearm...my best guess is a stylus problem.
Adam what tonearm do you have, the rega I had used a magnet to control the anti skate. For me it happened like you say...all of the sudden. The further into the outer grooves the arm/cartridge rode it started making a distorted sound and then would actually jump backwards a bit. I thought it was an A/S problem and could never solve, it also did not do it on every album but did on most.

I made several adjustments to the arm and could never solve the issue. I moved on to a new tonearm and cartridge so I do not know positivly what the problem was...even though I suggested it is a cart problem above for you, I am fairly certain my problem was with the tonearm and most likely A/S...
Adam just jumped to your system page...nice! But I do see you are using a reba 301....do you have another cartridge you could try out?
