Achieving the Perfect Tracking Geometry
If your turntable tonearm and cartridge aren't correctly aligned, not only do you compromise the performance of your turntable, but you may also actually damage your cartridge and LPs.
"It is extraordinary how often arms arrive set up at the wrong pivot-to-spindle distance or with no ability to move the arm to the required overhang," reports Edward Barker on the audiophile website 6moons.com for December 2005. "In any case, it is vital to check that the correct distance has been achieved; otherwise the levels of distortion produced by tangential arms will cause serious deterioration of performance."
The Feickert Universal Protractor is the best we've found for aligning your cartridge with ultimate accuracy. Use it with tonearms that have an effective length from 8.6 up to 17.7 inches.
Simple Operation, Rewarding Results
The goal of the Feickert is to help you achieve a tracking geometry that suits LPs in a perfect way. Operation is simple, and the results are very rewarding.
"The Feickert protractor has precise markings for all tonearms from 9-inch Rega equivalents right up to 16-inch monsters," says 6moons.com. "The markings are every millimeter. Using the aluminum caliper, it is a simple matter to check the correct pivot-to-spindle distance with great precision… "
The calculation of parameters were carefully carried out according to Lofgren's equations aiming for reduction of the overall RMS distortion level caused by deviations from the ideal tangential position of your cartridge while tracking your records.
"All in all, this is an invaluable tool," concludes Edward Barker for 6moons.com. "Highly recommended."
