Hello, I've done some research on my humming psu and its because the laminations of the iron mesh in my transformers have come loose and vibrating as the polarity changes.
If i open the PSU up could I do something to the transformers (like sort of put a bit of pressure on the iron mesh to firm them up) - as a try?
I'd get it RMA'd but I would like to skip that as I've swapped a lot of stuff with them and they're very mad with me.
Thanks
