So I have need of a 25k-B pot. I have quite a few 50k-Bs laying around so I figured...Is it possible to just put a 25k resistor on the 50k pot legs and have a virtual 25k-B? And if so, what legs do I use, 1 & 3? I assume this wouldn't work with an "A" to "B" designation. I know this has been discussed probably before but I didn't see anything.
