Inner groove "Rumble"

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.

Might help if you say what turntable, what tonearm, what cartridge.

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.

Lewm ..... all there... please click on my system.
Nick ..... I cleaned the stylus, but no improvement. For years, I've been cleaning the stylus after every listening session.
Marakanetz ..... as Pops says, why would the phono stage only cause a problem with the inner grooves ?
Pops ..... I just don't understand why a "stylus or tonearm problem" would happen all of a sudden like this.
