  If the power LED on your Line Magnetic Amplifier is off, here's what you can check: * First, make sure the power cord is securely connected to both the amplifier and the power outlet. If it's loose, plug it in firmly. * Second, the main fuse might be out. Replace it with a fuse of the same type and value. * If these steps don't solve the problem, there may be internal issues. In this case, it’s best to contact your local dealer for assistance.
