Size: Outer diameter approx. 37.6mm, height approx. 14.0mm. Shaft size approx. 6.2mm, the type that fixes the shaft with a flathead screwdriver, so it can be used with both USA and Japanese pots. *There are some scratches on the silver part. For repair and customization of vacuum tube amplifiers, stereo amplifiers, antique radios, audio equipment, guitar amplifiers, and effectors, as well as for dressing up guitars like Teisco and Guyatone. Images 5 & 6 are reference images for size comparison. Image 7 is a reference image for installation (only the knobs are for sale).
