Can the cheap Williams true blast potentiometers be replaced with one of the volume potentiometers that are used in the mthps3?

I am having lots of problems keeping this potentiometer in contact, and clean, which is causing the speaker to not work properly.16206115643523832484831396936997

Note that Mike's Amazon recommended part is so-called horizontal mount where you adjust the trimmer from the "top."  The trimmer in your picture is so-called vertical mount where you adjust the trimmer from the "side."  Check dimensions to confirm you have clearance if mounting right on the board itself.  Most trimmers come in your choice of orientation.  OTOH, since you're talking about MTH-style volume adjustment, their trimmers generally reside on a tiny board of their own on a harness to the electronics.
