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)?

Poorly set or calibrated anti-skate would be a reasonable cause resulting in the audible effect you describe. Tom

Joe Grado said to me not to use anti-skate that is was an unnessary evil. Funny thing though when I bought one of his wonderful tonearms a couple years later it had an anti-skate adjustment. Tom

Stringreen, I spoke to Mr. Grado several times about his cartridges, headphones and tonearm. He always took my calls and was there on the job. He was very outspoken and dynamic in his beliefs in his work and his designs. Certainly nothing wrong in that. The midrange quality of his designs were a direct reflection of his vocal skills. Tom
