Oh,
I've also seen statements "checked by my tech(or dealer) for excellent operational condition few weeks ago"
After unpacking and connecting the unit, you find that the balance knob is off middle position almost to 2 o'clock and indeed you need to keep it there otherwise channels are out of balance. After slight tech-check with DMM immediately found that one of the output transistors gone short. Obviously there was some "cut the cwap" conversation involved about how-to-be-honest-101.
