Help... my turntable is alive!

I am hearing a heartbeat through my turntable between tracks, and also when the music is very quite in the song's track. This noise is at 33 BPM in sync to the turntable rotation. It's very quiet unless of course the volume is turned up, but can clearly be heard. I don't think its rumble as it has a distinct "heartbeat" sound.

My turntable is a Basis 2500 with a Graham 2.2 arm and a Goldring 1042 cartridge set at 1.70 grams tracking force. Any guesses here? Is the bearing on the turntable shot?

Thanks

Dear Cleeds,
Yes you're quite right. It's unlikely the OPs problems would be compounded by this but it's a possibility.
If fact you've inspired me to acquire a spare for my own turntable even though it's not too old.

Back when I had a Linn the oldest belt was about 20 years old! Regular updates meant previous ones would be only 2-5 years old but were routinely discarded by the dealer even though they were fine.
Thanks for that anyway ;)

If you think that your turntable is dangerous then disarm it!

Just a thought, but have you checked whether the records on which you hear this noise are properly centred? I believe that the cause of your noise could be the eccentric motion of the arm as it navigates an off-centre record.
More to discover
