    Around the Switchcraft speaker outlets for "auto" impedance switching. Just
    an affectation? If there to keep out grime , it does not work, and
    intermittent contacts with almost every one I see.
    So each time I see one I clean the contacts and fit a small nylon cable tie
    the tip contacts bunch and
    around / through the wiring to the other pins and draw tight enough to
    retain a circular form
    and add pressure to the closing contact but not so tight its not possible to
    plug into or extract a plug.
