Today I was sitting in my office where my SEX resides. After listening much of the day, I left the room and came back to neither tubes glowing, no light from the LEDs and the amp producing no sound at the speakers. The transformer was still hot and the fuse still intact.
Thoughts on where to start troubleshooting? Is best course to simply begin running through the checks in the assembly manual?
This amp has been very reliable for the past 2+ years - I recently moved it across the country and had no issues in the months following.
