I've never had this problem on any other cart ... the old original stylus doesnt do this .... am I missing something ?
Is it a Shure stylus? I have 2 V15-III's.... I have never had to have it track as heavy as 1.2 grams, they have always given me best results between .75 and 1 gram...less and the low end won't track correctly and going much over a gram made it look like the lever was really taking a beating.
Both mine have original Shure styli....if you are using an aftermarket stylus, it might not be that good...and since you say the old stylus doesn't do it...well....
