I made a power supply that uses a small audio transformer and a regulator, in addition to a few discretes. I'm getting what I want out of it but, the transformer gives out a high pitch noise. From what I've read this is due to the construction of the core, constructed of plates that vibrate at certain frequencies. The problem for me is I think the core is solid ferrite. I don't want to destroy it to find out for sure. And I'm not positive that I'm right about the plate vibrations anyway.
Is there anything I can do to silence the hum?
