Hi guys. I bought a used Axe Fx II XL+ and it works just fine. However after inspecting it for any potential damage I noticed something moving inside the unit. More precisely, it seems like there's something moving inside the flyback converter. I discovered it while shaking the unit, which of course is not going to happen very often but I just wanted to check for anything loose inside just for peace of mind. Fractal support suggested I opened the top panel but couldn't find anything moving around. To be more specific, the only way I can hear this thing moving is if I move the axe fx back and forth (along the axis that goes from the front panel to the outputs in the back). If I shake it side to side or even put it upside down I can't hear anything. Any idea on what could that be? I know nothing about electronics so my first thought was that there's some sort of component that's "supposed" to do that. Again, It works fine but just wanted to check with you guys just in case someone had this happen to them or if I'm probably worrying too much!
