30 amp variac instead of an autoformer?
Hi, I've been looking for a 30 amp autoformer for some time. I wonder if this item would "fill the bill". 30 amp variac $169 Here is the company listing: variable ac transformer

Heck, you want expensive, look at the Furman AR Pro- will take anything between 80 and 267 volts and put out 120 vac +-4%. 97% efficiency...
$4,000. 50 lbs, rack mount. I've used the 2400 watt model a bunch for pro audio, never used the 3600 watt model though.
The AR-PRO uses a design based on a 25-tap toroidal autoformer. The toroidal design assures minimal leakage of stray magnetic fields and a highly efficient, compact package. The AR-PRO's circuitry monitors the incoming line voltage with each cycle. If a voltage change requires that a different tap be selected, the new tap is electronically switched in precisely at the zero-crossing, to avoid distorting the AC waveform. If necessary, the AR-PRO can switch taps as often as once each cycle.
