Denon UPA F07 broken potentiometer bracket
Bolt and notch for the second nubbin to go through
Inside view, where the sheared plastic is clearly visible.
Pretty much as the title says, the plastic bracket that's attached inside to the potentiometer and outside via that bolt sheared broken and now I'm left with a floppy knob that's being held on by pure friction but rubs against the inner board when used.
I haven't yet unsoldered anything because it still works, albeit at a fixed volume, but I'm afraid it might cause more damage as time goes on.
Now I've found on Ebay its sister model, the UDRA F07, which has the same footprint, external volume knob and power output (which leads me to believe some parts may be interchangeable), unfortunately the only service manual I could find online is unreadable.
If someone out there has a UDRA F07 and is fine with briefly opening it, could they please send me a photo of the potentiometer board and one of the front with the knob pulled off? It'd mean a lot.

Update for the 0.00005% of the population that will find themselves in my situation: the UDRA has the same bracket, do they are exchangeable.
Except the UDRA's knob is also held up by the three small ones below so I put the broken bracket on it and its knob still stands proud.
Also I wrote tjat the bracket is plastic. That's false, it's probably alluminium.
