Noisiest. O-scope. EVER!

I have the world's noisiest o-scope! It's an old ADC-200 computer based parallel interface box. harmless enough.
However, once it's plugged in it emits the most infuriating squeak I've ever heard. It's like it's full of really tiny rape alarms or something.
While it may be a bit low spec compared to a modern scope (20MHz, 10 in dual channel mode), it's a whole 5MHz faster than my vintage farnell DTC12 (wooo...) and it's PC based therefore a storage scope (YAY!!!!)

I'm going to do a bit of poking around and see if this is normal or fixable. Or I might just wrap it in foam and operate it from a draw...
