Good and timely question Scott.   Every 10 years or so I rebuild these AZ
and EL rotators and replace the bears and low temperature grease I think
that the pot is always the weak link and never gets attention.  I have 3
sets of these AZ/EL rotators to maintain ( mine, club's and friend's ) so
about every 3 years I have at least one set of them on the bench.

I look forward to other's responses to replacing these pots that are
unenclosed, exposed to condensation, bugs etc, with  a looped centre wire
flexing/coiling/uncoiling with each satellite pass.

Our club has a 5400 Elevation Rotor with a bad potentiometer (wires on the
winding broken). 

The part number is Vertex Q9000408, but I contacted them and they say this
part is no longer available. 

Anyone have a source for an equivalent part or another alternative?
