Up for sale here is this new stereo (dual) 250k ohm audio taper potentiometer. This has a loudness tap on each channel and is perfect for replacing vintage loudness-tapped volume controls. The shaft is a 1/4" ribbed split shaft, and it rotates in little stepped increments.  It's a little stiff but will work great. This will work great to replace the volume control in the Pioneer SX-535, SX-636, and more.  The shaft is 25mm from chassis mount to tip.

Wiring this up is fairly simple.  The old potentiometer has six terminals on the bottom and two on top.  The new potentiometer has 8 terminals on the bottom.  On the new potentiometer, when you're looking at it from the shaft end, the six terminals on the LEFT side are wired up just like the six on the bottom of the old potentiometer.  The two terminals on the far right side (one in front, one in back) are wired up just like the two terminals on the top or side of the old potentiometer--they're the loudness tap.
