Do you know here to get constant voltage transformers that don't hum or buzz?

The only ones I've seen that don't buzz are the factory ones in Zenith Chromacolor II sets, and the secondaries on those aren't right for a tube set.
I run an air filter 24/7 that makes white noise, and hide the transformers behind a console in the far corner of the room on a dogleg of the room I can't see from viewing position to minimize it's volume...If I cared a bit more about the hum I'd build what Hollywood calls a sound blimp or put it in a different room.
Especially when I moved in but still sometimes the power grid makes one non-negotiable... when there's MANY bloom inducing grid voltage dips a minute unregulated B+ sets become unwatchable.
