Plenty to be seen in relation to how a Cart' can deteriorate and be rejuvenated in the Link. There are also plenty of Lyra's seen, which some will be from a era close to your Akiva's period of production.
Asking for a FGS Stylus on a Boron Cantilever with a very modern rubber as a Damper will get my deepest of interest.
This has been very successful when used on certain Ortofon Cart's that do not get the Ortofon Replicant Stylus, as the base Stylus.
