Buying Guidance

Confirm compatibility against your specific vintage model's original specification where possible — vintage parts inventories vary in availability, so an exact period-correct match isn't always guaranteed.

Maintenance

Vintage components, particularly magnets and adhesives, may need re-conditioning (such as re-magnetizing or re-foaming) before reinstallation rather than being used as-is from long-term storage.
