I experienced a FAILURE of azimuth position.  Ordered a new pot, and it 
turned out that the failure was that the lead going to the wiper had 
broken.  It is very fine wire and broke due to flexing.  Poor design, in 
my opinion.  I reinforced it with some tape backed by a tiewrap in the 
appropriate place to take the stress off that connection.

Good luck!
