There is another way that I have used but for lower currents than you are into. It means getting a large Toridal transformer of suitable VA.. It want to be large so that it has a big hole in the middle 
Then get some flexible wire, the silicon covered sold at swaps would be a good bet. Wind say 8 turns through the hole and measure what volts you get, again you get the turns / volt. Then you need a long length of wire and wind it through the hole bringing out taps as before. To make it easier to handle the wire you could make a long thin spool.
Terminate, supply and measure as before.
Of course you could go DC and use a series regulator: there are plenty of designs around for Battery Eliminators. With those its possible by just using different voltage setting resistors to give you the steps you need.
Supply and measure as before.
