Review on Enhancing Turntable Performance with Strobe Disc: Tests 33-1/3 RPM and 45 RPM Speeds by Leticia Ellis

High quality cartridge alignment tool! I purchased a Hudson Cartridge Alignment Transport Disc after spending a lot of time researching the alignment options available. I am very happy with my decision. The disc is of very good quality. Alignment marks are easy to read. This is a beautiful work of art. It mounts directly over the platter spindle and is held securely in place. Because of the full disc coverage, I find this to be a more stable method of carefully placing the stylus on the two main anchor points. I tracked the cartridge correctly for several minutes. Supplied in a beautiful "album" style case. Use it on my old turntable. Cool tool.
