I now need your help and no better place than this and you: it's time to change the stylus of my VM540ML and I have never changed a stylus' cart before as I used Denon's High Output MC DL-160 and DL-110 and as you know these are use and discard. How do I remove the old stylus without damaging the cart? Do I have to dissasemble the cart from my Goldring GR-1 TT tonearm or can I do it with it mounted? And now the opposite, how do I put the new stylus and can I do it with the cart assembled to the tonearm? Keep in mind that in addition of not having done this before I have a disability on my shoulders which are almost destroyed. I can do everything I did before the accident that messed my shoulders up but on a different way as I've lost some mobility on my arms and also lost force,but not being able to lift a heavy weight shoudln't be an issue at changing a cart's needle. I'd appreciate your help.
