I have just bought an electrical keyboard synthersiser online, but the AC Adapter takes a 120Volt input. I am just wondering whether the following arrangement would be safe or not?
Mains Socket Supply-> 240V-to-120V transformer->120V-to-12V Adapter for the keyboard->Electrical Keyboard synthersiser
Also, is it safe to plug the 120V input AC Adapter directly into the 120V socket of the "Shavers Transformer" which was marked "Shavers Only"? Why is it that "Shavers point" are for shavers only?
