    Getting a bit flakey on a Behringer SL2442 mixing desk.
    Just 3 control lines out , ground and 2 lines taken high via 4K7 to 5V. What
    would be inside , 2 sets of 10 resistors? All wrapped up again , different
    problem repaired and only noticed at final checks so cannot investigate.
    Owner only uses one effect so fingers-crossed will not need replacement or
    its fellow

    And then non-volatile memory storage of the last stored position . So
    presumably you can turn the control when powered off and it will display the
    stored setting when powered on again.
    So there is a good chance of getting inside one to clean etc and return it
    to productive use .
     
  3. I found a couple very common types available very cheap from Onkyo in the
    U.S.
    About $1.00 each.

    I've had good success cleaning them for the most part, but I did have a very
    nasty re-do on a JVC stereo which had a slightly different encoder, seemed
    to work after cleaning, then wound up having to order the original part from
    JVC when the unit came back.

    It was buried on a sub-board in the front panel of a tabletop stereo, so the
    double extra-special labor to get in there a second time probably cost me
    As cheap as they are, I generally replace them with the Onkyo parts, since
    most models use one of the two Onk parts I stock.

    I did have a Marantz SR-18U recently which had a "special" one, and no
    longer available from Marantz. I cleaned it, and it worked OK, but I was
    kind of sweating bullets on that one...

    This one has a co-axial switch for the memory change function and as far as
    I remember no where in that 2x3 foot panel , any space to squeeze a switch ,
    apart from having to cut a new hole in the top pannel.
    So recondition of the existing or constrained to the main-dealer for supply
    of a direct replacement
