RE: 78 rpm stylus for 33 rpm records? Can it hurt?

The larger tip won't fit into high-frequency groove undulations. Although the groove is V-shaped, the radius of curvature of groove undulations become smaller than the radius of the stylus when the frequencies get higher. Therefore, the larger stylus simply passes over the high-frequency undulations. That's the whole point of line-contact styli and other more sophisticated stylus shapes, which allow the stylus to follow high-frequency groove undulations more accurately.
