    I have 3 resistors for RGB signals which need to be regulated to the same degree. I've used potentiometers to regulate a single resistor before, but how so I go about regulating 3 different ones and having a single knob to do so...

    Any help is much appreciated:D

    What you'll be wanting is a triple-ganged potentiometer. It's quite simple, really - three pots sharing a common knob. Good luck finding one in the resistance and taper you need, they're not the most common of beasts. Here's one in 50 kΩ, if that helps.

    Thanks - I actually need a 250 ohm pot, although finding any 3 gang ones is proving to be pretty hard, let alone any of the correct resistance:(
