551, 51, 51A clock radio
#9

If you don't have a 5000 ohm control, a 10,000 (10K) or 20,000 (20K) ohm control will probably work just as well. All this control does is to shunt a selected portion of the incoming signal to ground, depending upon the setting of the control.

Just be sure any replacement is linear taper. An audio taper control will work, but will have a very large change in value over the first third or so of its travel. Linear taper pots change gradually, in a linear fashion, from "low" to "high". For audio circuits, an audio taper pot is ideally suited. However, in this application, a linear taper pot is better.
