That type of amp usually uses about a 2.5 to 3kva for 2-channel. Rated current draw on a similar commercial amp (Crest CA18) is 26 amps for 1/3 power typical max output. I'm pretty sure the trafo is only 2.5kva but at that size it could do 3 times that for half an hour before it thermals.
Try doing that with a switchmode and see what happens.
