I checked with my (German) electronic supplier (www.reichelt.de) and found these two pots: for $8: 20K, 10 turn, at temperature coefficient the specs say: "20ppm/ degC (standard values, wire only)" http://www.reichelt.de/?ACTION=3;ARTICLE=2544;PROVID=2402 for $0.50: 20K, 25 turn, but cermet with 100ppm/degC http://www.reichelt.de/?ACTION=3;ARTICLE=2722;PROVID=2402 So probably the first one, right? But does it really have such a small temperature coeffient? The "standard values, wire only" confuses me.
