The Wellfleet is the seventh model up in the slightly confusingly named Oyster series of cartridges from Sumiko. This takes the successful Moonstone recipe and tweaks the stylus assembly further again, with a nude Elliptical diamond mounted on the very small 0.5mm diameter aluminium cantilever with low mass magnets. The output is fairly low (by MM standards) at 3mV due to the reduced magnet size.
This cartridge can also be downgraded by fitting the Rainier, Olympia, Moonstone and Wellfleet stylus assemblies (or play 78s with the RS78 stylus).
