Inner groove "Rumble"

Dear Adam18: Seems to me as a cartridge suspension or a tonearm bearing problem.

It's dificult to say for sure so all we here can only speculate about.

regards and enjoy the music,
R.

Raul, How can you rule out the most obvious (to me) possibility that the platter bearing is worn or low on lubricant? He most lately said that the rumble is audible at all points across an LP. But he has lost interest, and so therefore have I.

Dear Lewm: Well, that already posted by other persons and I think he needs all the possible " reasons "/speculations.

Regards and enjoy the music,
R.

Hey Guys........
No ..... I have not lost interest in this forum. Sometimes "life gets in the way" and Audiogon takes a back seat to other things. The bearing seems fine, and I think I've narrowed it down to a cartridge problem. I'm going to try to borrow a similar Rega cartridge and mount it to see if that improves the situation. Thanks for all your help and thoughtful advice ! I really appreciate all the interest you guys have shown, and it certainly is a pleasure being part of this fine Audiogon community ! I will keep you all posted as things progress. 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 !
