Hi. Don't know if this is the right place, but I have Apogee AD16x that suddenly started to make a very high pitched noise, which I could clearly hear coming from the PSU, I think from inside the circle. The name of the PSU seems to be "Umec UP0651S-02 Power Supply T104618". Instead of trying to find the component that is faulty, (if it isn't obvious) I'd rather by the a new power supply. I have enclosed two pics, the circled one is mine, the other is one I found on the net, but the net version has a electrolytic cap more, so I wondered if they were interchangeable?
