Alps Blue Velvet dual/stereo 250K audio taper volume control pot for high quality audio. Solid aluminum 6mm diameter shaft fits vintage and new USA knobs designed for 1/4" shaft USA pots: I tried a bunch of old DAKA-WARE, Fender and other set screw fixing knobs and found that they fit. Six connection lugs, special ALPS audio/log taper. Approx. 29/32" long solid shaft can be custom cut to length desired with a simple Exacto hobby saw. 25mm wide, 25mm high, approx. 25mm deep (measured from the round mounting extension of the diecast face near the metric M8 .75 threads to the back of the blue plastic case...). Designed for PC or 'point to point' installations; it's a bit tight but you can wrap and solder your wires to the silver plated lugs for 'point to point' circuits. These Alps pots track about as good as the discontinued Black Beauty version, much better than 'generic' volume pots. Made in Japan.
Metric M8 .75 thread mounting nut and flat washer are included.
