OK, I just bought a Fisher Integrated tube amp and there's some hum coming from the main transformer. You don't really notice it when you are listening to music, but when it's dead quiet, you can notice its humming. Is that normal or should the transfromer be dead silent? The hum can be heard when putting the ear close to the transformer or, even from a couple of feet away. Can the transformer be "fixed" to eliminate the hum? All input appreciated. Thanks.
