"Mechanical" azimuth alignment is the only way to go if your arm has the capability!
The diamond needs to be "visually" aligned.
Set the diamond on a CD and look "head on" at the reflection of the tip, for correct azimuth alignment.
The electrical "balance" (output in each channel) of a cartridge is almost never exact. You need to adjust the balance control for the proper centering of the image after azimuth is set.
The "fozgometer" is BS!
