I don't understand why you're having the problem, but being in a country
with 120V, I can say that there is NO way 120V should be "too high",
every outlet I've tested at home and at work has been AT LEAST 120V,
some as high as 123V, so if your transformer is rated for 120V/50Hz
operation there is NO way the 120V is the issue.
