Retipping a cartridge is a silly idea. There is much more stuff inside the cartridge that wears out such as the suspension and coil connection wires. The manufacturer will remanufacture the cartridge giving it an entirely new armature/cantilever/ stylus assembly. Oh, what happens to the coil wires is that years of vibration work hardens the metal and eventually they just snap. Always have your valuable cartridges remanufactured by the original company. Always keep an eye on your stylus with a microscope. Do not wait until you hear something. That’s way too late.
Re-tipped phono cartridges
I noticed a lot of ads for re-tipped phono cartridges are suggesting this is an improvement over the original. I respectfully disagree. Regardless of the new stylus the integrity of the original design has been compromised. Think of it as a fine Italian automobile with a blown engine. It can be fixed but is it ever truly the same?
