Ringing (which you see in the photo) can appear to be very different from one measurement to the next, depending on the test equipment (mainly probes and probing technique.) The digital supply output could be exciting a resonance in the test setup. I'm assuming that the damping ringing pulses are occurring at the switching rate. (Need some scales.) You might also check to see if this appears on more than one squeezebox. Maybe you got a bad one. - Dave -- Dave D _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
