Go and grab THIS..
It WILL keep your line voltage to about 117 or so..EVEN IF the input reaches about 130 or MORE.
it is rated at 350W...BUT a few members hav ethem and have used them on 5'S and 7's..with NO ill effects..
Know ONE thing...it is NOT isolated though...if that matters. but for line cotrol...it will NOT.
