The noise from a traditional 220v-to-110v 50hz step-down transformer is due to the fact that the frequency is not converted up to the required 60hz needed to power American 110v 60hz clippers correctly.

However, because of the slower cycle at 50hz, these two arms cannot return back to their original positions quick enough.
