Oberheim DX Tuning Knobs

Hi!

Does anyone know of a suitable replacement for the Oberheim DX tuning potentiometers? The little black ones sticking out of the back.

I’ve got a couple that are broken–one has a snapped shaft and the other seems to have been pounded so the whole thing is shot.

Thanks!

Did you ever figure this one out? I have a similar problem. Thanks.
