Isn’t it best to list services with which one has had a personal experience?
Third Party Services - Phono Cartridge - Retip - Refurbish - Rebuild Services.
A Thread to add a List and Links to show where Third Party Services are available to offer a Retip - Refurbish - Rebuild, as well as make known the Cart’s that have been returned as a successful remediation.
If there is any information known off, that is seemingly related to the subject, there seems to be no reason not to copy/paste the info to this Thread, as means to consolidate information that might prove useful to somebody showing an interest in using a Service that is not from the Cart's Manufacturer.
