Instead of a Variac, which you will constantly have to adjust manually, why not try a voltage stabilizer, or isolation transformer?
Maybe something like this would help.

high voltage's affect on amplifier performance
in much of nassau county, voltage readings have increased during the last 3 years.
at one point i was getting readings as low as 117 volts. this past summer, readings have increased to 126. currently, readings are around 122 to 124 volts.
i have a hypothesis that frequency response is affected by input voltage to a tube amplifier.
is there a scientific principle, or mathematical equation which can support my hypothesis ?
if so, i might want to purchase a variac.
thanks for your help.
