You want a linear taper, not a log taper. The wattage is very low as this is just a control signal. Your best bet would be to measure the existing one. Chinese labeling is not always trustworthy. Mine was 22k but it is an older model. Not to be too harsh, but based on your questions, are you sure you know what you are doing? If you are looking for a replacement, the shaft is not the typical 1/4", "D", or splined. It is a smooth 4mm shaft with a clamping knob. Again, YMMV as all this is subject to change, based on production run.
