Need a replacement knob for T1 Tonematch

Hi, I’ve owned an L1 system for about n15 years, and I am a huge fan to this day. Somehow I have lost the Big control knob. Where can I buy one? Thanks for any help.

This is most likely a standard knob, not manufactured by Bose. Take a look at some big electronic components supplier; Digi-Key comes to mind. They have 11275 types in their catalog ranging from 18 cents to 639$ for a bag.

Thanks for that…I’ll give it a try.

Did you find a fitting knob? Asking because perhaps others can benefit from the experience.

Otherwise, perhaps post a photo and measurements. Of special relevance is the diameter of the axis and whether it is knurled or not.

Cheers!
