This Panel Mount 10K Dual Linear Potentiometer is a dual-ganged potentiometer that will satisfy all your stereo-signal needs. Instead of just one potentiometer, you actually get two separate pots, 'ganged' together. Turning the grippy shaft twists both standard linear-taper 10Kohm potentiometers. It's smooth and easy to turn, but not so loose that it will shift on its own. We also offer this potentiometer in a singular configuration.
Unlike many of our other potentiometers, this one is not breadboard-friendly. The pins are about 0.2" apart so it will fit into a breadboard, but the two rows are close together so you'd short the two halves. Thus, we suggest soldering wires to the pins as necessary, using these in a perf-board that doesn't have the rows connected, or designing a custom PCB.
Once you're done prototyping, you can drill a hole into your project box and mount the potentiometer using the included washer and hex nut. We've got plenty of matching T18-splined knobs that you can pair up.
