Up for sale, we have a rare vintage Shure Dynetic M3D Stereo Phono Cartridge with stylus. This is the sought after early version cartridge with the foil dynetic sticker on the top. The cartridge was mounted and tested. It's the first time we have seen this cartridge come through our shop and we were pleased with how it sounded. The left channel impedance measured 330.8 ohms on our Fluke meter, while the right channel measured 332.0 ohms. The listing has been updated with pictures of the stylus taken under a microscope.
