In Reply to: Correct Loose Laminations? posted by Soundripples on April 3, 2007 at 06:45:09:
Depends on the construction and how easy it is to take apart.If there is no obvious way to tighten up the clamp, varnish impregnation might help. This is best done in a vacuum so that the varnish gets into all the nooks and crannies.
Years ago when I was young(er) and stupid(er) I varnished a noisy but otherwise excellent 300VA power transformer by immersing it in a pot of marine varnish which was heated up to near boiling point to expel the air and make it thinner. I had already made a jig so that I could suspend the XFO by its wires above the pot to drain. It took AGES to harden, didn't look very attractive and I could not get it back into its half screening can.
But it stopped humming!
