Tonearms with no anti-skate adjustment


I am in recent possession of a Grace 704 uni-pivot tonearm, which has no anti-skate adjustment. This is not optimal IMO, but should I really be worried?

Thanks for all the input.  It sounds perfectly fine to me...no mistracking, no imbalance in the channels, no distortion that I've noticed.  But I should do some comparison listening tests in highly-modulated tracks using one of my other turntables, and see if I notice distortion in the left channel.

The Grace 704/714 tonearms did not come with anti-skate, so no parts are missing.  They are low-mass arms (6g from what I've researched), and stock pictures of them had F9s mounted, so I really think they are meant for high-compliance cartridges. @viridian Where did you see that they were designed for low-compliance?

@cleeds I saw as well how older VPI arms did not have anti-skate, and were also uni-pivots.  But Lederman notes in his anti-skate article (on SoundSmith's website) that VPI eventually added AS adjustment, probably at the behest of users.
Anti-skate is very important. I would stay away from cheap tobearms which omit this feature. 
And what of expensive tonearms that omit anti-skate like the Schick. Are those better?

I owned a 714 and it worked best with low compliance cartridges, for me. The 704, 727 and 747 mated best with the F9e, etc. IMHO. So I did not see it anywhere; I was an owner. All of the repeated info on the effective mass of the arm seems to originate here:

The internet seems to merely echo unsubstantiated claims until they are no longer questioned.

But for a moment, let’s give that low effective mass number credence. I’m with Mr. Lederman. Your Shure V15 V , or other light tracking, high compliance cartridge, may not show signs of overt mistracking in an arm sans anti-skating, but the wear characteristic on the stylus will be uneven. I believe this also implies that groove wear will also be uneven as vinyl is softer than diamond. Audio is a thousand different religions. Pick yours.

I was very proud about myself when I got 90 microns ''pure'' from

my combo Sumiko 800 + Ortofon MC 30. But then I have read

Van den Hul's warning not to use too much anti-skate needed for

such values. Too much anti-skate was worse according to him

then no-skate at all. By all his carts one get anti-skate values for

 his sample.

The other problem is that this ''force'' also depends from record

radius. So, obviously, the same anti-skate for the whole record

is also problematic. I ever owned the only tonearm with ''variable''

anti-skate  : Sony 237 with an ingenious ''curved'' lever with

different anti-skate related to record radius. In addition there

was provision for stylus shape. I give up anti-skate not because

I don't believe the theory but because there is no way to do this

correct.
