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,
I think you are are confusing angular quantification of VTA with *someone's* attempt to indicate the direction of a VTA adjuster on a tone arm. This "positive" or "negative" attitude does not attempt to account for angular displacement just the general attitude of the tone arm post-adjustment.

If you can offer a better "convention" that describes it by all means do so and we'll use that instead. ;)
We await your deliberations with interest.

Bill

 Sorry, but I'm not confused at all. There's a singular accepted definition for VTA, and a "negative VTA" simply isn't physically possible.

Dear Cleeds,
Since you haven't offered an alternative convention but merely stand by your original position there's little more to be said. I'll keep using that convention because it does describe the tonearm's attitude with respect to a neutral reference point. ;^)

@moonglum the alternative convention that I always use is simply "tail up" to indicate the cartridge sloping down towards the front, and "tail down" to indicate the reverse. No chance of confusion with this one.

Good suggestion Folkfreak. Indeed, I've often used those terms myself. ;)

Of course, since they are synonymous, if we substituted one of these into Cleeds "objection" it would have emerged as, "There's no such thing as a tail-down VTA! That's physically impossible!"
(Just to show I can also quote out of context when required ;)

Have a good day :)
