A:  Hello Bobbi, Thank you for the inquiry about the 126-Watt Impedance-Matching Volume Control. We do not sell replacement knobs on our website. We believe it would be best to reach out to the manufacturer for assistance. The manufacturer is Petra Industries, their customer service department can be reached at 800-443-6975.

Fabulous! My surround sound controllers were 25 years old. The old ones had yellowed and were dingy! These made a marked improvement ! I love them! A perfect refresh. And the sound is even better!!! A perfect fit!

They arrived in highly damaged bag with tire marks on it and minimal padding. The 12ga connects would not keep my 16ga wires connected during the installation process.
