this can't be right. P.V.C has a melt temperature of about 170 to 185 degrees, i know that the grooves are tiny and thus extra fragile but still, the cartridge can't create that much friction, besides, the stylus is constantly moving, it won't stay on it's contact point long enough for the friction to create enough heat, every cycle it has moved on to the next set of grooves.
the tiniest bits of vinyl at it's necessary melt point would just carbonise and they would have to be subjected to sustained heat.
there's only one way to find out, try it.
also, someone else remarked on here that they had a neighbour that played kylie minogues "i should be so lucky" repeatedly, and it could'nt kill it, and that was on a higher speed 45 single
