Is my anti-skating too strong.


I’m trying to adjust the alignment of the Ortofon Black Quintet cartridge on my Music Hall mmf 9.3 turntable.  When I put the stylus down on the alignment protractor, the tone arm pulls to the outer edge of the turntable.   Should I disable anti skating when doing alignment or is it set too strong?  Obviously haven’t done this too often.
Also, when listening to the anti skating track on The Ultimate Analogue Test LP, there is noticeable distortion at the end of the track which indicates too much or too little anti skating.  Any guidance here?

Yes - I triangulate the three methods.

Step 1 - I use Soundsmith's technique of setting by dropping the stylus between the inner grooves in the run off and doing an initial set.
Step 2 - I then use the Allen Wright method, running up from low to high antiskate. There is a sweet spot where the sound is most natural.
Step 3 - I check the cantilever to make sure it is straight. You can also use an eccentric record to check if the cantilever shifts more to one side than the other.

Allen Wrights methodology is much easier to perform if the VTA is dialled in accurately, because that with the correct antiskate gives you maximum ease and naturalness of sound, the most harmonically complete.

Using rules like x% of tracking force is wrong because you dont know the compliance in the horizontal plain, it can be quite different to the vertical compliance specified.


Clearthinker, will an airplane fly without wings? No, I do not have to hear one. All I have to do is look at it. Every tonearm must deal with the laws of physics even if you do not understand them. Bow Wow. (dog barking). I think you might want to consider changing your user name. I'll change mine to "dogmatic" 

@justmetoo, friction is much lower in the record groove than it is on a blank record. This is counter intuitive but lets see if I can explain it so it makes sense. The major determinant of friction in a record groove is VTF. Next is the surface area contact. The greater the surface contact the lower the friction. What will have greater friction, the point of a knife or a marble. 
In the groove the stylus has two contact points and distributes the VTF between the two. On the surface of a blank disc there is only one contact point and the full VTF bears on it, the point of a knife. At the same VTF line contact styli will have less friction than elliptical styli. This is why line contact styli can get away with higher VTFs without increasing record wear. Yes, modulation plays a role but minor in comparison to contact pressure. In the groove the contact pressure is 1/2 that on a blank disc.
Dear Mijo, The friction force is independent of surface area.  The formula is f = uN, where f is the friction force, u (Greek letter "mu") is the coefficient of friction between the two bodies in contact and varies according to the materials of which they are made, and N is the "normal force", which is the force by which the two bodies are pushed against each other, in this case gravity.  However, I do agree with you that a groove-less LP does not mimic the actual skating force generated when one plays a record.
MC, In your efforts to be flippant, to pretend everything in the world is simple and that you uniquely understand the simplicity, and to belittle others, you are truly annoying even me, who doesn't give a rat's patootie.  I could refute your refutations of stuff I wrote, but I won't bother.  Suffice to say, it is not that you are wrong but that you are always half right, yet you claim to be completely right.

This is not at all accurate, correct, or true you have a profound, distinct, extreme lack of knowledge and understanding of very basic, elementary, introductory physics.
I don't want to get into whether friction is higher or lower on a blank record vs. in the groove--there are too many variable to consider.  For one thing, I have not seen mention of the fact that, when playing a modulated groove, the stylus is being dragged at a MUCH greater velocity (the path of a modulated groove is much longer per inch of record circumference) and there is inertia of the stylus moving side to side to consider as well.  

None of this matters as to whether Ledermann's approach of using the blank side of a record is valid.  He acknowledges that this does NOT duplicate actual playing conditions, but, his experience has shown that it results in a decent proxy for a correct setting.  He has a lot of experience with examining stylus wear so he knows a thing or two about what achieves even wear.
