@thom_mackris Thank you for that hint. I have 3 styli that are 2nd hand ("lightly used") and I have checked their condition under a microscope. apart from a lot of fibre at the neck of the cartridge the needle and rod seem to be in good shape. But as it will be a small while until I use them, I can spend some constructive time to delicately clean them, which on close inspection, the needles and rods are dull; in good shape but with vinyl build-up. The previous owners have tried to keep them clean with dunk gel pads, and the occasional brush, but not the recuperative effect of ME. Thanks again! A.
