Albert's and Jockey's advice will probably do it for you, but I'd like to add a couple of refinements(?) which, like chicken soup, "couldn't hurt" ;--)
Plug the amps right into the wall. I won't go into my diatribe about conditioners/filters here, but I think they are more a liability than an asset, if you have ded. circuits anyway.
Second, if you are using single ended ic's between your amp and preamp, and if they are the "shotgun type" -- two signal conductors plus a floating shield -- (most brands are these days), point the arrows toward the preamp, not toward the amp. This insures that the shield is connected to the preamp (where it should be.) Make sure the preamp is grounded -- you can lift the other grounds safely AS LONG AS ALL IC's ARE CONNECTED; TURN STUFF OFF IF YOU ARE GOING TO SWAP/DISCONNECT THE IC's.
My $0.02.
