Repair trim potentiometer on one channel for myself?

[lemon]

Hi guys,

this is not a Windows but a Motu problem, but unfortunately there is no "hardware only" board, so I'll try here.
I have a problem with my 896HD, and after explaining it to our Motu distributor they told me that the trim potentiometer has to be changed.
No I wonder if I could do that for myself, as the 896HD is already 5 years old I have no warranty at all.
Somebody knows if which type of trim potentiometers are used in the 896HD?

Thank you very much
