I have a spider III 75 watt amp that I hadn't used for a while. When I now turn it on all lilights turn on and work as they should but no sound comes out. If I plug headphones in it works fine though. I have tried a factory reset but the problem still persists. I have also tried reseating the wires that are connected to the speaker but this does not have any effect.
Not sure what these symptoms signify, could it be that the amp think headphones are plugged in when they are not?
Thanks in advance for any help.
