If you're paying for a custom rewind, get extra taps above and below your
usual "nominal" voltage.

I would suggest 100, 105, 110, 120, 130, and 135 -- plus 2x all those,
within reason by the rewinder's prices.

Line voltage here in central Texas ranges from a measured 122 to 131 before
seasonal brown-outs -- I once lived in a house that showed an 8 v drop
every time somebody made a slice of toast!
