    Hello,
    I'm wondering if anyone knows where I could find a center tapped pot? I need it to build a baxandall tone circuit. I've looked on mouser but didn't seem to find any. Would anyone know where I could find one or possibly a replacement ?

    Thanks a lot,
    Damien

    Hello,

    Do you have the schematic of this baxandall tone control ?
    The circuits I know do not need a centre tap potentiometer.
    Take a look at this example from ESP. (A little down the page).

    Those things are getting to be as rare as chicken lips. About 20 years ago, I had to change the loudness control on my Lafayette receiver, and it was hard to find even back then.

    You can "fake" it by building a voltage divider between the two hot legs of the pot and tapping off there. It should be about the same resistance as the full scale pot resistance.
