I think My monos were damaged during a recent lightning storm. There is power to the amp, but the amp is producing very little output. I turned the volume on the Candela pre-amp to 12 o'clock position and I can barely hear the music. And what music that are produced sounds a little distorted. I think there are 2 separate fuse bank in the monos (external and internal) and I will try that first, but what are the fuses I need for each fuse bank? Anyone else encountered this problem before? I've read a few posts where the fuse on the amps were blown and the amps were completely dead....producing no music. But in my case, the amps are producing music but at very low volume and sounds distorted. Thanks for any help
