[comp.sys.mac.misc] My Mac Plus whines and Screams when left alone!

My old Mac Plus has a habit of making a very loud, very annoying high pitched
tone when it has been on for a while. I remember reading something about it
in a MacUser or MacWorld a long time ago and I was wondering if anyone had
any clues. The tech people I know would fix it for me, if they had a better
clue what they were looking for. Someone had the idea that it could originate
from a metal band around the flybox (???) that could have worked itself loose
and started vibrating. Please, any clues as to what it could be or where I
could find out would be greatly appreciated. Thank you.

Hey, my MacPlus is doing something similar, but rather than issuing an
annoying high pitched tone I get an annoying low pitch knock. I left it for
the repairs and the techo took $50 and said he could find nothing wrong with
it. I have the suspicion the noise must be coming from the speaker, but the
source could be just about anywhere, probably a nasty spike of electric
charge is going through my Mac's guts, one day it will probably fry to death
(as my Mac 128 did once, remember the old beast?).
