  • surfmaster pi repair

    Does anybody know the dc resistance of the headphones? Been asked to repair a unit and found the headphone o/c, they are yellow Bilsom ones. Expect that by the time I break through all the sealing they will be broken anyway Thanks

    They use piezo elements, not speakers, so they will look like open-circuits.
