Hi all-
 
    Perhaps it is a linear taper.  During repair I measured the resistance change as I turned the control, and seem to remember it as acting like a log-taper pot.  Memories are a funny thing, though, and I'm probably wrong.  But, a linear-taper pot might be easier to find in an electronics shop parts bin.
 
     Thanks-
 
     Bruce D.

log would be the same as audio taper.
pots are either linear or log/audio.
