Question about NAD C350 2-Channel Amplifier
When I try to power it up it makes a loud humming noise and repeatedly blows the fuse. appreciate any help. I use this speaker for small gigs. do you know where I can find replacement parts for gemsound speakers?
Disconnect any input cables from the amp. Turn down the volume controls and disconnect the speakers. Power back on. If you still blow fuses with nothing hooked up, have the amp fixed.
If the fuse holds, shut down and connect the speakers, leaving the volume controls down. Power up and see if your fuse holds. If you have hum, an output transistor is most likely shorted. If you have no noise, SLOWLY turn up the volume controls and listen for the hum. If all is quiet, turn down the volume controls and connect your input cables and turn the volume back up. Noise? check your cables!
