Default MBOX Pro (3) Power Supply

Hi all, I need some help please. I need a replacement power supply for my mbox pro.

After hitting forums, looking up the mbox3 tech spec, finding as much as I could I understood that I needed a
"9V, 4A, 36W, Plug-In Power Supply (Center Positive 2.1mm x 5.5mm plug)"

They are not easy to find.
But I found one!!
After ordering it, I received it this morning.

But it doesn't even fit!

So which part did I get wrong?
The plug is definitely the correct spec based on the above.

Thanks

In UK and they come with a barrel to accept a 2.5mm pin, which is wrong. (too tight)
The Mbox 3 pro has a 2.8mm pin on its housing
INPUT: 100-240V, 50/60Hz, 1.5A OUTPUT: 9V, 4000mA, 36VA
Note its also a 4amp (4000ma) output
So i had to get a barrel with an inner 2.8mm hole, to replace/solder the 2.5mm one. Cant recall the outer barrel size but I think 5.5mm is correct.
