Hey Scott...

I would consider a 5 KVa mini pig with a 1256D variac set up for 140VAC out.... or if you can find a step up transformer that can supply 130 -145 VAC that can handle 3-5 KW...

Don't need a step up transformer for the full power. Use the boost/buck style connection with a low voltage (20V) transformer. Primary across the line, secondary in series with the line.

2.4kW @ 120V is about 20Amps.. so all you need is a 20V 20A transformer, which is about 400VA. They're a standard electrical supply house thing, or there's lots of 24VAC out 120V in transformers around for applications like sprinkler controls, landscape lighting, low voltage lightning, etc.
