I bought a 5A Tripp Lite unit that puts out 120v with 89v-149v in. The
devices are made for people with sloppy power or who suffer brown outs.
The unit also has EMI and RFI filtering. I believe the unit works by
first creating DC which kicks off an oscillator that is boosted to
created new/clean AC.

These units are very inexpensive. About the same price as high end line
conditioners that only filter. I don't understand why they aren't used
more. Seems to me they would be very beneficial and a heck of a lot
better than the filter only units that run in the thousands. They come
in sizes over 20A. (The only downside I see and it's small is that they
generate a magnetic field so they should be kept away from other
electronics and speakers)
