Thank you both for your thoughts. I think I will be sending them to Andy for retips only.
Chris, another cartridge that I will be sending to Andy for repair is a Vandenhul MC1 that I "nuded", mounted on my ET and used nude (on and off) for years (mounting nuded transducers is a favorite activity ;-) ) Anyway, attracted ferrous particles was never a problem; however, once during mounting the magnets attracted a mounting screw (won't touch that one) that I thought was non-ferrous and it severed one of the thin wires going to the back of one of the cartridge pins. Btw, the improvement in sound from nuding was not subtle.
