Review on 🎶 Hudson Hi-Fi Turntable Cartridge Stylus Alignment Protractor Kit - Enhanced Vinyl Player VTA Azimuth Ruler - Turntable Stylus VTF Force Gauge - Phono Cartridge Stylus Alignment Protractor for Optimum Performance by Rodney Mendoza

Before purchasing this protractor kit, like everyone else, I adjusted the arm height of the platter by observing it from the side and using my best judgment as to where true horizontal is. The acrylic protractor eliminated the uncertainty at this stage as it is now clear where the plane is using the block as a reference. I've used an azimuth sensor that was downloaded and printed and I've always been skeptical that the spindle bore is really dead. . Preventing paper from curling up when not in use was also an issue, but this has now been mitigated with the hard plastic version that came as part of this kit. Such tools are easy to buy from Revain, which greatly simplifies the work. These tools come in handy when you're looking to replace cartridges for testing or listening, and the only extra you'll need is a little digital dial for measuring and setting downforce - they're also available from Revain.
