Norman, With all due respect to the venerable AR turntable, could it be that bearing friction is causing some AS force? (I owned one myself, of course, back in the 70s when I first got interested in "hi-fi".) My Triplanar sounds obviously distorted in the R channel when I cut AS to zero. On the other hand, no less an authority than Doug Deacon used to recommend removing the entire AS device from the Triplanar and going without it. (Although I seem to recall that he did also talk about applying some minimal AS by using small rubber grommets in lieu of the Triplanar AS weight.) Why two different end-users of the same tonearm would come to different conclusions, I do not know. I do set my AS at minimum on all my tonearms; then I listen for L vs R distortions. I also check the cantilever after the first 50 hours to see whether it is biasing to one side, in which case I add or subtract a tad of AS, as appropriate. The net result is probably not far from where Almarg ends up, or if anything I use even less AS.
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
