Amplifiers can come with or without power supply, the type without can give the option of one large power supply for all three, but with the kind of sizing you have it might be prudent to go with a power supply for each, as per the originals.
The thing is that large amplifiers with built in power supplies puts the cost up quite a bit, So by using the power supply part of the existing amps, gives you a bit more flexibility in chosing amplifiers, saves money and provides voltage compatibility with the motors. If you post the part number of the present amps I may be able to tell you what type they are.
