I bought a Monolith M5100 5 channel amp, powers up no sound need help. I opened the cover and the fuse is soldered a clip on/off cable was disconnected to the toroidal power supply. I reconnected the cable and no success. There is no warranty from seller but will reimburse for repairs. Any suggestions of service centers or anyone wants to look at this amp Gene talked so highly about? I am in central Florida. Al 480-430-2704.
