Left Channel LP Distortion


I have noticed that more than a few used LPs I have purchased have periods of distortion in the left channel only. This is on LPs that have been thoroughly cleaned.

Other LPs, and new LPs have no such distortion.

Is this a sign of groove damage from having been played on an improperly set up table?

What would cause this damage (if it is damage)?

How are you going to sell tonearms if you don't have anti-skate adjustment..that's why Harry at VPI has a device for his. Thedudiotweak..Did you know Joe? Did you know that he sang with the Met? Nice guy!!
Lewn...damping - to use it or not...is not an indication that your tonearm is right for the cartridge you use. Some cartridges require some, some cartridges require none, and some require lots. I have a Benz on a VPI, and indeed some damping makes the cartridge sound better...too much is harmful to the sound, too little and it can be improved. Experiment and listen. Having more VTF is usually better than too little. It sounds as though you have too little
Could be improper anti-skate ( I like NO anti-skate)or too light VTF...or trolls.
Azmoon... I have tried anti=skating. The proper adjustment of a/s is impossible. The amount of a/s depends on soooo many variables (loudness, complexity of recorded signal, vtf, sylus shape, etc.) that are constantly changing, it is virtually impossible to set it correctly. VPI suggests no anti-skate. Having a VPI arm, I tried it, and then tried it on a number of arms. I found that anti-skate always (tuff word - I haven't tried ALL arms) effectily dampens once side of the stylus (outside). Also, all arms I've tried has a mechanism for anti-skate, that interferes with the purity of the signal. I don't use any anti-skate with very satisfying results. To each his /her own.
