Can I just swap out a 9 volt battery with a DC power supply?

However, in general you can simply replace a 9V battery with a regulated 9V DC (!) supply. DC is important. The power supply should have an "equals"-sign printed on it after the 9V, where one of the two straight lines is dashed. If it is labeled "9V~", then it will put out AC (alternating voltage), which is surely not a replacement to a battery.
