Quadra 630 Whining PSU
Posted by: marmanold on 2018-06-28 21:35:49
My beloved 630 has been unplugged for about a year until today.  When I plugged it in there was a faint whining noise coming from the capacitor.

Is this whine cause for concern or normal?  I honestly don't remember this whine before, but the wife and kids were out and the house was abnormally quite.

I unplugged it just in case.
