I recently got a 2010 Orange AD200B head and it has worked absolutely perfect for about the month I've owned it but I experienced a problem earlier. I was playing through it and the light started to cut out but the sound or power didn't change at all. I stopped for a few minutes and tried it again. The light came on, it powered on correctly, and the sound was the same as always. I played for a few more minutes figuring since the sound didn't change, chances are it was just the lightbulb, I had turned my volume knob on my bass down for a moment, and then i turned back around to look at my amp and the light was off again. I turned my bass volume up again and no sound came out and I then immediately shut the switches off and unplugged the amp. I checked the fuses and they were all still totally intact. Does anyone know what this might be?
