Ideal SRA Calculator
Once you have determined your "Native" Stylus Rake Angle (SRA) using the WallySRA *, install the front/back (SRA) Type I or II WallyReference blade (Type must be appropriate for your tonearm) and enter the information in the calculator below. The result is a figure that you should raise or lower your tonearm by - using the WallyReference as the measuring tool - in order to achieve a perfect 92 degree SRA under dynamic (record playing) conditions.
* Or other method in which you can confirm:
1. Top surface of the cartridge is perfectly level
2. Nominal VTF is applied
3. Photograph is taken exactly from the proper angle
WallySRA available in late 2020.
