I have Two MMBU 5021 units. They both power on and get to all zone error 10, so that looks to be fine. Unable to test further, therefore listing as for part only.
Physically they have heavy scuffing and some minor cosmetic denting. May have been stored outside. No major physical physical damage as far I can tell. No accessories, selling as is.
