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 .

Dice,

Actually Ghostrider is correct. A component must be designed to be balanced or it just won't be balanced.

What Bob is refering to is running a balanced connection between components. And Bob and TWL are correct that this is possible and only requires a set of balanced to single ended transformers. If the noise is caused by pickup in the interconnects then the balanced cables will produce a benifit. If the noise pickup comes from other sources, then the advice from Driver should be helpful.

I think you should use both suggestions for best results.

Regards,

John
