Up for sale here is this new stereo (dual) 50k ohm audio taper potentiometer. This has a loudness tap on each channel and is perfect for replacing vintage loudness-tapped volume controls. It is a 50k ohm pot, and the sections will test around 50k-60k ohms.  The loudness tap is at around 9.5k ohms.  The channels are not perfectly balanced but should be fairly close.  I tested one of these and the two sections tested at 53.11k and 62.15k ohms, and the loudness taps tested at 9470 ohms and 9625 ohms.  The shaft is a 6mm ribbed split shaft. The shaft itself is about 10mm long.  Please see my pictures for details and measurements.
