My ballast is so old, that it's made in the United States (NJ in fact).
Apparently there is no repair; it can only be replaced, but it can't be
found, so it has to be replaced with a different ballast, which may have to
be T8 because they may no longer even sell T12 ballasts.

I understand that due to the 110/230 voltage differences, fluorescent
tubes and their ballasts are wired differently on each side of the
Atlantic, but over here converting a fluorescent fitting to LEDs usually
involves removing the ballast and starter, is that not the case over there?
