I'm looking for the sound that an IBM Selectric makes, specifically the loud hum when it's on but no one's typing.

I'd love to use it as white sound since it was a common noise in my home when I was a child. (My grandmother took in typing.)

I've found secretmojo's great sample of typing on a Selectric but the he stripped the hum out. It is pretty loud, but what I'm hoping to find.
