I bought it used, so there’s no way of knowing exactly. I haven’t used it much. I had it on my SL10 for a week or two then bought a normal body for it and put it on the SP10.
I got an original head shell for the SP10 and the OM seems to be too low for it (it was fine with the Yamamoto). I got round it by putting a felt mat on top of the rubber one but it isn’t ideal, hence moving it on
I’ll pm you a pic of the stylus taken with the usb scope
