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

Since you haven't offered an alternative convention ...
Because there's no such thing a negative VTA, you could say "lower the pickup arm" or "reduce VTA." Either of those would accurately state what you were thinking.

One of the reasons it's important to understand that there's no such thing as "negative VTA" is that, had the OP initially properly set his VTA, he wouldn't have had his phono cartridge bottom out in the first place. VTA can be set pretty reliably, btw, if you have patience and good tools. There are a few devices that can help set VTA, but this one is my favorite. When you consider the cost many of us have committed to LP playback, the price isn't unreasonable. It's much better than relying on guesswork or estimation.

I must be honest. When you first questioned the usage I thought you might be “winding me up”.

Based on your last 2(4?) posts I now recognise that your confusion is genuine.

I'm not confused at all. There's simply no such thing as "negative VTA." I realize that you are embarrassed for having been exposed for your ignorance, but that's not my problem, kind sir.
