Grado - Red3 Phono Cartridge
Standard half-inch Mount
The Blue1 and Red1 models use a four-piece OTL cantilever technology, standard oxygen free wire in the coils and Grado's specially designed elliptical diamond mounting on a brass bushing. The Red1 model is selected from the Blue1 production run and meet higher test specifications. Approximately 10 percent of the production run will meet these standards and become Red1 models.
