@wbass , thats an Ortofon Cadenza Bronze which is still freakishly expensive to repair unfortunately. Thats the major drawback to MC carts, you cant just insert a new cantilever and stylus. My own fault though so I cant complain about it. Gives me an excuse to slot in some different carts for a while, prob good for me. @Biodegraded, there's definitely a darkened area on the tip of the stylus but I always took it as unpolished metal. The scope doesn't have enough resolution to exactly indicate if its metal or some thing on the cart but scrubbing with enzyme cleaner never took it off. So practically what am I supposed to do then? Scrub hard enough to break something ? One thing with the Zerodust, it builds up dirt and oil on it fast if you dont keep the lid closed and clean it often. So that dirt and oil could get on the cart, or if you used soap to clean it & that could transfer as well.
