They help reduce/soften the snap off noise produced by bridge diodes when conducting in the forward direction and then turning off when going into reverse bias.

Its funny how big that cap used to be. I've got some mylar caps from about 1961 in service yet, and they are easily 5x that size for the same kind of value and voltage. On the other hand, they are still fine. Tough dielectric mylar is.
