I've got a number of audio projects on the workbench, and of course, each of them requires different potentiometers. Instead of waiting for another box o' parts to arrive, can I substitute? What are the rules of thumb for that? While my first inkling is that it'd be the same as a regular resistor (e.g, 5-10% is generally close enough), I've been second guessing and, well, have confused myself in that thought experiment. I've never ~noticed~ tolerance ratings on pots, but that doesn't mean they're not there.
So within what ranges can I safely substitute? 10k for 20k or vice versa? What'd happen if I subbed a 500ohm for a 100k? Looking forward to some guidance!
