I have a VT220, and it's pretty cool apart from the high pitched whining sound it makes. I think I might have to recap it at some point

  That might be normal. All cathode displays made a high pitched noise, TVs included.

  That's the flyback transformer. It also means you're still young.

  My cochlear implant interferes with it actually. I'm intrigued to figure out why.
