What do you do about a squealing CRT? I've got this nice terminal which is
working, but it emits a high-pitched whine which is not only unpleasant and
annoying, but quite scary, too. It feels as thoughit's going to blow in your
face any minute.
The terminal in question is a green-screen TECO VA120.

Assuming the CRT doesn't have a crack in it, in which case it wont
squeal long, it sounds like a horizontal output transformer that is
vibrating at an audible frequency.
You might try tightening any screws you find around the core of
the H.O.T. (With the power off and the circuit discharged.)
