I have two 15V AC "wallwarts" that my meter measures at 18.23V AC with no load (I seem to remember it was 16.something when connected to the DSL box it came with) and produces a slightly bumpy sine wave at around 48V peak-to-peak on my old scope.
Question:
Is it possible and safe to connect the tips of these two identical adaptors and make something that's essentially a 15V, 0V, 15V center tapped transformer similar to the way you can connect two 9V batteries together to get -9,0,+9?
In other words connect the center pin of one connecter to the outside sleeve of the other to create a 0V point and the other two points would be 15 and 15.
