PDX-2000: Grinding sound when stopping a record by hand?

**HStanford1** · 02-16-2012, 08:34 AM

Every time I stop a record with my hand on one of my PDX-2000s it starts vibrating a bit, and makes an audible grating sound.
The platter is still spinning (as it should be) and there's no issue with playback, it only does this when I manipulate the vinyl.
What should I do?

Hmmm, and now it's not doing it. Do I just need to lubricate the motor and if so what should I use?

I believe the PDXs have quite a rough platter, that might be the problem

The weird thing is one of them does it and the other doesn't. I don't remember it rumbling before either :\
Any suggestions on lube?

That's weird. I'm having the same issue, except it's with my STR8.150s.

Did you get yours sorted at all? I called Vestax CS today but due to my poor sleep schedule I wasn't conscious when they called back

Also bumping for suggestions from any previous PDX-2000 owners.

Also is this a good lubricant for the spindle?
It's called "Liquid Bearings" http://www.ebay.com/itm/BEST-synthet...ht_1657wt_1396
Or something like this? Technics Lubricant Part No. SFW0010 http://www.ebay.com/itm/Lube-oil-Tec...2#ht_500wt_922

I had this same problem with my Stanton St-150's. I found out it was just from using warped records on the non-slippery sides.

Usually, a warped record will have a side that is slippery while the other side tends to have a lot of grip. Spinning the record back or just stopping the record with your hand can cause the record to vibrate/make noise because its trying to gain traction on the platter. Also, not all warped records do this. It seems like it has to be warped just right to get this effect.

Try flipping your vinyl over or using different records and see what happens.

Wow HedBangerBoogie you were totally right, I think. Oddly enough I'm not getting issues even with the TC record that was causing the issue however...
Also the table that I thought was screwed up seems to have more resistance/torque. During Timecode playback on a track at 140pm it plays at a constant 139.80 +/- 4
There is also a drastic difference in torque between the tables. Where as one table I can backspin/cue with relative ease the other I have to fight against to stop my record. It also seems to take a bit longer for it to get up to playing speed, but not an absurd amount, even with the Start control set to immediate start.

Would this mean it just needs some lubricant so the spindle can spin easier? I know I keep going back to this but I bought the tables secondhand and I don't think they've ever been maintained in their lifespan. I had to buy a DeoxIt pen to clean out all the contacts, there was quit a bit of funk in the tonearm/headshell connection as well as the RCAs.

I would just buy new time code records if it really bothered me that much. No need to put any kind of lube on the spindle.

You can always try fixing them yourself using the guides from youtube. Just search for "how to fix warped records". People tend to have mixed results when using those youtube guides. I've always just dealt with using warped records or bought new ones.
