John -
 
Try a 5K 1/8 Watt resistor across the two outer lugs on the pot 
itself.  This should stretch the range of the knob.

Another and better way is to just use a 10-turn 10K pot. Just 
substitute it for the original. It won't disturb the resistor value 
with an added parallel resistor across the outer lugs will. 

I have a Bourns 10-turn and from the wiring indication on it, you 
should be able to rewire it the same as the original panel pot.  

Hope this helps you.
