Not normal, sound like excessive current somewhere?Is it normal for small 6VA 15v transformer to vibrate like this?
Either a winding, or something on the load, it is possible the bridge has shorted?
Disconnect every thing from the secondary and see if it persists.
If earthing the secondary, make sure the DC side is not grounded also.
