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

Just a thought - your belt could be sticking.  Whenever I change belts on my Thorens 'table, I "bathe" it in baby powder, then gently wipe the excess powder off with a clean paper towal.  This tends to minimize belt sticking.  It's a cheap potential remedy.

Bondmap ... A very thoughtful idea, but I have checked twice. There is no sticky feel to the belt, or the platter anywhere. I could order a new belt, but I don't want to start down the money path until I know I'm at least on the correct path.

Thanks ... John

Money path??? A turntable belt is a trivial expense compared to the cost of maintaining proper vinyl playback equipment in a Music Reproduction System and all of the gear that supports that playback including alignment tools and record cleaners and sooner or later you are going to need a new belt anyway so why not buy one now and set to rest whether that is the cause of your problems?

A replacement belt is $170. Not exactly a trivial expense.
