Auralic Taurus Mk II scratchy pot

Hi all,

I have been enjoying the taurus mk II for years but sadly recently the pot becomes scratchy and sounded distorted if turned, myself have no diy and repair ability and here in Hong Kong we have been locking down and shops closed so I cannot find a repair shop to ask.

May I ask here anybody have idea could the ALPS blue be replaced with a DACT stepped atteunator or sort without modding the case? if possible then it would be better for me to fix and upgrade it than buying another expensive amp.
