Inner groove "Rumble"

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.

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?

Hi Pops.. First of all ... Thanks a lot for your compliment on my system.
No, I do not have another cartridge. The Exact 2 and RB-301 were bought together with the table. But I will follow your suggestion and try to adjust the anti-skate a bit. I'll keep you posted as to what happens.
