granger.frederic said:...no difference if the amount of voltage polarization is the same.
the only difference is that if you put the 60V on the diaphragm, it will be more prone to collect dirt with time.And you have to use a coupling capacitor between the diaphragm and the tube grid.

This effect on the level of a percent , but it matters . Therefore, more correctly supplying power to the diaphragms and not the central electrode. Then the work of the capsule is more precise and correct .
