What would it take to balance a stereo power amp ?

I am in a band and own the P.A. system that we use . In the interest of eliminating hum and noise I have decided to run it balanced . The main FOH system is tri-amped with an electronic crossover going into three seperate stereo power amps. Two of them have balanced inputs but one of them does not . The "unbalanced" amp is an older model that has given me years of trusty service and I don't want to replace it if unnecessary to do so . What would it take to balance it ?
Obviously , it would have to be an inexpensive retrofit or it wouldn't be worth the cost or aggravation . Any help would be greatly appreciated .

Both groups are right as far as they go.

1) Balanced outputs can be added to anything.
2) Having XLR outputs does not make the piece balanced. This is a design issue which obviously involves more than just outputs. Balanced circuitry is balanced throughout.

Whether or not this alteration will eliminate the 'hum and noise' is not certain, but your proposed solution is fairly inexpensive and easy to accomplish.
