Tonearms without anti-skate, damage to records?

@rsf507

@dover I prefer weight on a string 

Can you explain how you determine the 25 - 30% via this method?

Yes - you can use scales to measure the actual falling weight, it won't be exact because there will be some loss due to the mechanism ( usually friction ). However it is more accurate than most sprung or magnetic antiskate mechanisms.

2 examples - 

FR64S - this has markings on a pivoted rod that you slide the weight along that denote 0.5g increments in antiskate.  I actually measured using strain gauge scales the falling weight at each increment and was surprised to find the markings very accurate. Measuring the falling weight ( with the platter removed ) at various points across the record showed very little if any deviation as the rod went off horizontal.

With this arm I set the arm up such that the rod that the weight sits on is horizontal at the mid point of the record ( to minimise deviation ) - seems to work well.

Kuzma 4point - recently installed a van den hul Grand Cru with a specified antiskate force recommended by van den hul of around 0.2g - the only way I could achieve a level this low was to use a piece of bluetack carefully trimmed and measured on stylus scales instead of the metal weight - even Franc's custom small weight could not get this low. 

@dover   Please explain why you think the skating force does not change linearly as the record is played.  Surely it is just a question of geometry?

I never said that.

On a linear tracking arm there is no skating force.

On a pivoted arm it varies across the record.

Some Rega arms rely on magnetism for anti skate, therefore no adjustment. Are you certain that your arm does not have a similar anti skate configuration?

This is how the unbranded (actually Rega) arm works on the Avid Ingenium plug and play.

If a turntable/tonearm has the means to set or adjust anti skate, then I’m using it.

What’s all this about the weight swinging back and forth? Mine barely moves at all when a record is playing, no distractions, I don’t get it.

I’m in the  “I hate antiskate camp!” I mean no disrespect to any who believe in it and use it. More power to you.  For me, I’ve never heard a difference, seen a difference and have always had problems with skipping, miscuing etc. I use the bare minimum if it’s availability on a tonearm. That’s my two cents. 

No one appears to have mentioned the sound quality with regards to AS. I find that the music sounds less restrained with no AS applied to my 12" Jelco 850 tonearms.
