Multiple transformers buzzing

Dump the CFLs and install regular light bulbs and see if that does it.

are you sure this isn't whining capacitors? i find that more likely that power supply noise, especially since you describe it as high-pitched. i have dog ears and whining caps kill me. i've replaced multiple ones in my LCD monitor.

to me, all CRT's whine annoyingly. not sure if it's caps or something else, but i don't know if you can fix it...same thing often happens with PSU bricks.

I've heard whining caps before on video card VRMs. This noise is different. Am I sure? No.

I removed the CFL from dimmer switch and no more buzzing. Still weird, a dimmer switch with a CFL on a different circuit was causing harmonic distortion throughout the entire house.

It all comes from the same source.
