Arcam FMJ AV8 Weird Volume Dial

Can anyone help?


I have a Arcam FMJ AV8, all in pieces except the screen (going to respray it) as got it very very cheap.


Problem is, the volume dial will just not come off. I have taken out all screws, there are none left, there is no allen key hole on the dial, yet, I can lift it up a bit, then it just gets stuck.


Has anyone had the same thing happen?
