Is it possible to obtain a 78 rpm styli for an M7D cartridge? Are there any 78 rpm styli still available for any of your cartrdiges?
The M7D is a very old cartridge and Shure no longer offers a stylus for it. There may be third party suppliers that still have M7D styli. In the U.S., try The Needle Doctor at 800-229-0644.
The record grooves of 78RPM records are significantly wider than 33RPM and 45RPM grooves. For this reason, 78RPM phono cartridges use a wider diamond stylus. Note the difference in these Shure styli: 2.5mm spherical tip for the N78S; 0.2mm x 0.7mm elliptical tip for the N97xE.
