Antiskating too strong? Help please

Hello to everybody,

I was playing vinyl this morning with my Clearaudio Performance and I noticed that when I lift the tonearm at the end of the disc, the arm itself slides quite a lot towards the external part of the disc....does this mean that anti skating is set too strong?

When I need to put the needle down to start playing the disc I haev some problems as the tonearm slides really little towards the external part as well...

Certainly sounds like it.  What's it set to?  On most arms it should be set to about the same as the downforce (ie about 2g).  Rega arms behave differently, I've found.

That's not normal, no Smile

I don't know if there are any gotchas with the Clearaudio arm - probably need Ms Newsome around since I think she had that before she moved to some mental parallel tracker Biggrin

I would suggest you start from scratch as per the manual

http://www.clearaudio.de/download/laufwerke/new-generation/performance_en.pdf

and have the antiskating set to about half way, which should be OK for most cartridges, and see if that improves things.  The only truly accurate way to do it however is to get a test record or a blank (no grooves) disk.

Now I re-set the tracking force to 2,0g (20mN) as indicated in the manual. I reduced a little bit the antiskating and now is much better (it still slides right when the tonearm is colse to the center but by a very small amount). When it is at the beginnning of the disc and I lifit it, it stays straight

I noticed that the screw bolt of the anti-skating was a bit loose, so probably it moved a little bit yesterday when I carried back the TT from the dealer's shop

Many years since ... but i found thesignal wires as they passed thru the pivot, were slightly 'wound'. Little tweak/twist and all was well.

Don't understand, even with the antiskating set to minimum the arm still slides right when I am in the process of lowering the needle on the disc to play...

Crikey, is your TT set up at 45 degrees !!. Take the anti-skate off totaly and add it little by little. Try it with none at all first of all. Visualy, from the front, if the cantilever looks as if it is pulling to the right of the carts centre line add a little anti-skate then look again. This is interesting to say the least.

Have brought this thread to the attention of the Clearaudio sages Ms (and Mr) Newsome.

Thanks a lot JD.

This a new video with antiskating at the minimum level

The arms is still...but when I lift up and down it slides towards the beginning of the disc...so if I keep lifting/lowring I can slowly come back to the beginning of the disc (the external part). 

Here the video

RE: Antiskating too strong? Help please

Couple of questions before we make some suggestions:

1 - what cartridge are you using?

2- how are you measuring the tracking weight?

Thanks!

Clare, thanks for responding! I am using the Clearaudio Maestro MM cartridge and tracking weight of 20nM.
I am measuring the weight using the gauge provided by lowering the needle on the gauge and tighting/untighting the counterweight at the back of the tonearm till the gauge is parallel to the platter. 

Of course the needle is sitting on the 2,0g line

I know nuffin. I would ignore the action of the lift off mechanism since it is like a bulldozer lifting a pea. Suggest remove all weight so that arm swings above platter without any mechanical lift and determine how easily the arm moves laterally and virtically. You should be able to blow it easily with vitually no resistance. Use no bias ofcourse. ........

Lol. 

Binding cables is quite common tbh. But peeps tend not think about that.
