I have a Shure V15 type IV phono cartridge which I purchased new many years ago. The cartridge has always performed flawlessly and has very low hours of use. It has been in storage for several years.
Is there some component in the cartridge that degrades with time?
I tried to use it recently and found that the sound was "thin", lacking
bass and tracking extremely poorly. It sounded like it was overloaded and skipped all over the record.
The cartridge is mounted in a removable headshell. I swapped the cartridge/headshell with another cartridge/headshell combination that I have. The second unit worked, so it seems that the turntable (rega planar 2) and tonearm are still set up correctly (tracking force, anti-skate, VTA, alignment, etc.).
Is there some component in the cartridge that degrades with time? Is there anything I can do to correct the situation? Any help/information would be greatly appreciated.
* Yes. The elastic bearing that supports the stylus shank. Atmospheric ozone hardens it; like tire rot on bike tires.
Is there anything I can do to correct the situation?
* Sorry, there is not.
Beware of any replacement stylus that you may find for sale. Shure have not made the replacement stylus since the late 1980's, therefore even a new stylus may have a hardened bearing.
