    Hafler DH500 Channel Out Help Needed

    Hello everyone, I have a DH-500 that recently had the right channel stop putting out sound. I've read a few posts about ensuring the relay clicks when the amp it switched on (it does) and all fuses inside and the back are not blown. The light is normal on the front of the unit and the fan is...
