    Mackie SRM450v1 - Loud pop at turn on, followed by loud 120Hz Hum and no sound.

    The speaker worked before working on it. Initial problem was that the volume was cutting in and out when fiddling with the volume knob. okay, I started by also changing the filter caps as the old ones were bulging outwards and were ready to leak anytime soon. Nothing too complicated, for now...
