An older Uninterruptable Power Supply makes a very convenient way to
reduce line voltage. Find one of the old "loaf of bread" sized units
that uses the large 60 cycle transformer, rather than the newer ones
that use a switching inverter. Remove everything except the transformer,
fuse holder, outlets and switch. Use one half of the? primary winding
along with the 120 volt secondary to make an autotranformer. It will
drop 120 volts to about 109, which is much easier on older gear designed
for 110 or 115 volts.
