BAE Audio 1272 PSU problem


I just bought a BAE 1272 (rack version with external PSU) secondhand. I first found it to be a bit noisy and non-precise.

Now then I found that there is a very low volume buzz. And then I actually observed that the PSU is actually making a buzzing noise that you can hear directly. And the inner part of the PSU seems actually to be loose.

What would be your recommendations? Am I right to assume that this PSU noise is not normal?

Thanks in advance!

Here is the answer:

I found that to screws on the outside of the PSU where loose, I fixed that and the inner content wasn't t loose anymore. Didn't change anything to the problem.

I called BAE Audio:

David: I have one of your BAE 1272, is the PSU supposed to be dead silent or can it actually be making some slight noise?
BAE: It shouldn't make any noise
David: mine is actually making some noise
BAE: ... ah, you must have one of the older ones!
David: Yes, indeed (...). Is it normal or could it be a default?
BAE: I can not tell, but the design wasn't perfect then, and we know have corrected the design in our actual units.
David:: What should I do now, can it be repaired?
BAE: You could buy one of our new PSU? The price is 250$

David: can you upgrade my 1272, to your newer 1272 design?
BAE: no they can't
David: can you give me some information on how to improve my 1272 and correct the PSU issue myself then?
BAE: no

Did the seller you bought it from tell you the PSU was noisy? If not, why not?

He told me he didn't hear it. But he had the PSU in one room, and did his recordings in another room. I m seeing with him if he would take it back, but I m not sure yet if he agrees
