A reversible transformer comprises a high voltage coil. The coil is provided with a focal assembly connection terminal and electronic component mounting terminals. The focal assembly connection terminal is connected to one of said electronic component mounting terminals, which provides for the desired high voltage. When the high voltage is changed, the focal assembly connection terminal is connected in a simple fashion to a second one of the electronic component mounting terminals which is in correspondence with the changed voltage, thereby easily changing the focal assembly supply voltage.
