I'm having an issue that started today where the sound of my radio is turning off for a second and then turning on again for about a second and it keeps doing this constantly (see video below). This is happening on all inputs FM, AM, Bluetooth (through BT45-TOY). Antenna was replaced about 6 months ago. I've taken out the radio and checked all the connections behind the radio. I was hoping one was loose, but they were all connected. If this is the amp going bad, is there a reputable place that repairs them?
