Mine is normal until after the scope has been turned on fortoggle quoted messageShow quoted text
about 30 minutes, and then it starts going "Brummm..... Brummm..."
I suspect a capacitor failure, as it is annoying, and would have
caused notice if it were a "normal" condition.
Annoying, though it may be, I can't see how it would cause any
harm... unless it presages a total failure.
What it isn't is a bearing failure, or lack of lubrication. My
fan spins for what seems like half a minute after power is turned

I don't recall mine ever doing that. I'm very sensitive to noise as I investigate anything I can't identify, so I think I would have noticed it.
