Humming on new Conrad Johnson MF2200


I just received a "new" CJ ML2200. I hooked it up to my Luxman R117 receiver (for now) and it hums like mad. Is this normal (I hope not), do I need to change something, or is the amp defective?
Thanks

Did you get it from Northampton Audio/Spearit Sound ?? To answer Jack, they made a special purchase of CJ's left over stock of the older MF amplifiers. So they have new ones including the 2300, 2200 and 2100. If you got it there, call Dick Moulding, he will surely help.
