[TowerTalk] [Bulk] Need a G2800DXA pot

[Grant Saviers]

IIRC it is a "standard" 1/4" shaft pot.  The tricky part is to get one 
with the necessary angular rotation.  I learned this recently in 
replacing a joy stick speed control pot in a boom lift.  Measure the 
mechanical angular range of the bad one and also the resistance angular 
range (you might get a reading if opened and cleaned with contact 
cleaner).  Then check catalog specs carefully to get a match in 
rotation.  Also check the shaft and thread protrusions, although some 
washers and a hacksaw might be needed to get a fit.  In the end, after 
installing one that had insufficient mechanical range, I needed a $10 
pot, not a Chinese $2.  Digikey and Mouser have links to the detailed 
data sheets.  The Honeywell industrial controls pots might set you back 
$30 if one is required.
