Anyone use 100v or 220v gear with a transformer?

Is there a downside to using a 100v or 220v amplifier with a step-down or step-up transformer to convert to 120v?

Depending on the windings, hot coil wire could change the resistive load, thus leading to slight voltage fluctuations. Yes? No? Opinions? You will probably have to change you main fuses, especially if going from 220v to 110v.

The USA standard is 120v +/- 5% [or 114v to 126v]. So at best, you'll be running at a 14% over-voltage; at worse, a 26% over-voltage...OUCH!
