RE: Thanks a lot, but still one question

You really need to know the effective length of your tonearm to make a valid decision on mounting distance. If you believe its effective length is different than 229-mm, you should measure it. One way to do this is to measure from the tonearm pivot to the center of the headshell between the two cartridge mounting slots and add 9.5-mm. If you get 229-mm, then 211-mm is the correct mounting distance. If you get a different effective length, you can calculate the correct mounting distance from the following equation.



You need to select two alignment null-point radii and I recommend 66-mm and 121-mm. These alignment null-points will give you the best performance for modern LPs with a modulated groove envelope in-between groove radii of 60.325-mm and 146.05-mm. For example, if your tonearm's effective length is 229-mm, the optimum mounting distance would be the square root of (2292 - 66 x 121) = 210.84-mm. This is approximately 211-mm.

On the other hand, if you believe the mounting distance should be 214-mm, then your tonearm's effective length would need to the square root of (2142 + 66 x 121) = 231.91-mm or approximately 232-mm. Consequently, you need to measure your tonearm's effective length before you can determine the optimum mounting distance.

Good luck,
