Hi, I have been running my Beepre for over a year now with no problems and have been really satisfied with the sound quality. This morning when I turned the system on there was/is a loud mains frequency hum from both channels independant of source or volume level. I can still hear music behind the hum and I am wondering if there is a blown capacitor somwhere or if a ground has become disconnected somewhere. Any advice on troubleshooting very welcome. Thanks Tony.

I would start with a voltage check and report any oddities here.  Also let us know what your AC line voltage is.

And, not to state the obvious, but let us know if a visual inspection has turned up anything that looks disconnected or damaged.
