[TowerTalk] [Bulk] Need a G2800DXA pot

[Al Kozakiewicz]

Beyond the mechanical specs, I'd assume you need to make sure it is a linear taper electrically.

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.
