Tonearm pivot lube


Does anyone know if it is a good idea to lubricate tonearm pivot points? If so then what should a person use?

Only if the manufacturer recommends it. You can build up a lot of gunk by improperly lubricating a bearing. It sounds like you are talking about a unipivot. If this is the case you would be trying to lubricate an upside down bearing, the lube is going to wind up all over the place.
As Viridian and Dan_Ed suggested, there's no generic answer to your question. It depends on the tonearm. Many unipivots are designed to be lubricated/damped around the bearing but some are not. If lubrication/damping is called for, the optimum fluid varies from arm-to-arm as well.

If you're asking about a particular arm, please identify it. There's a good chance someone on this board will have experience with it.

Of course you could always ask your dealer (if any) or the arm's manufacturer (assuming they're still around) or even read the owner's manual! Many manuals are available at www.vinylengine.com
Thanks for the info. The arm is a Bio-Tracer on a Sony linear tracker. I was a little hesitant to mention this as either Sony, or it seems linear tracking, get very little respect from the audiophile community. There does not appear to be lube on the pivots but I think I might try a very small amount of teflon grease. My thinking is that I may be able to run the pivots with a slight amount of pre-load if they have some lubrication. The service manual says nothing about the tonearm pivots. Any opinions on this would be greatly appreciated.
Thanks again

Hey 80stech, we do everything from Lencos to Walkers around here so don't be shy about asking for help with any table. There may not be someone with an answer but I've never seen anyone turned away for having "approved" equipment. Linear tracking is highly regarded around here, although it is usually expensive and complicated with the systems we crazies tend to gravitate to. It would probably be a good idea to post on Audio Asylum as well. There are probably more users of that particular table there, and on a few other sites as well.
