Ancient AR Turntable with NO anti skate


A friend had me over to listen to his restored late 60's Acoustic Research turntable.  While listening, I noticed that the somewhat awkward looking tonearm had no anti skate.  Looking closely at the stylus assembly, it wasn't drifting or pulling toward the center spindle.  It seemed to track clean and true through the entire LP.  The arm is the original stock AR arm and couldn't be more that 8.5" or 9" in length.  I am just curious how AR pulls that off with such a short arm?  I have seen several 12" arms (Audio Technica for example) that dispense with anti skate completely but never a smaller one.  By the way, the table sounded wonderful and the cartridge was a Denon 103R.

Thanks,

Norman

My first 'real' TT was an AR....simple, straightforward, the only thing it lacked was a 'lift' mechanism, since nimble fingers sometimes aren't...*G*

Anti-skate is a very subjective issue...some notice it, others don't.  I addressed it by going into tangential arms of various stripes.  But that was my response.

If you like it, keep it.  Don't let the means spoil the enjoyment of the music.... ;) 
bdp24,

I did the same thing with my Dual 1229 when I replaced the original tonearm with the Grace 747, only I did the machine work. 

The AR tonearm is crude, but I have to admit it sounds good.  Obviously many others felt the same way.  I was reading that it out-sold every other turntable for a decade by a 3-1 margin.

Well said.  I don't remember many quality tangential tonearms in the 70's.  Rabco?  Phase Linear had a sweet arm on it's 8000 turntable which I believe was built by Pioneer or Series ONE for the Japan market. In any event, it was a superb arm.

Norman,

I believe you are correct the Rabco was the first accessory (separate component) tangental arm.  But by the late '70s several Japanese companies offered tables with tangental arms.  I had one of the Pioneer units (picked up in Japan by a Navy buddy) which was nearly the same as the Phase Linear version sold in the US.

Bruce Thigpen worked for Maplenoll, designing their air-bearing tangental arm prior to starting his own company, Eminent Technology, in 1982.  The first ET product was an improved version of that arm.  During the '80s Souther and other companies also introduced tangental tracking arms.

Back to the AR, VTF was not the only adjustment with that arm.  There is a set-screw on the underside to adjust arm length for stylus overhang.  However offset is fixed because headshell slots are not provided.

Doing a little more reading on the first SME arms that had no anti-skate an early reviewer 1960 commented that he loved the arm but not the fact it came with no skating compensation.

It was suggested to "tilt" the table slightly with the resulting compensation added. A simple fix from a time when you were left
to deal with concerns however one could..
