Hi Moose - looks like you answered your own question. One of the (however many) components you disconnected/connected is either not connected properly, is using a cable that has issues, or is plugged into a different AC circuit than it was in previously. Start with the basics- amplifier and speakers with nothing else connected. If no hum, then connect the pre/pro. - If humming- there is your problem. If not, then connect first source and keep repeating until you find the culprit. Good Luck!
