 bent and very squared off at spots?   
 I've found that mains is hardly ever a nice sine wave. All of my transformer
 outputs look a little wonky in some way. 
Are you looking at the output of the transformer while the bridge
rectifier is still connected?   You may be seeing distortion due to a
bad diode in the bridge which may then explain some of the additional
problems downstream.
