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.

i have a power traffo designed for this, it will use a 2inch CL stacked to 5 inches, i am going to use a mandrel made from acrylic to wind thecoils...
the secondaries will be 4 separate coils of 50 volts each, and will use 4 bridge rectifiers and 8 10000ufd/100vdc caps...
