This unit was purchased new and has very little use. This unit has the volume pot and looks great with the only signs of use is where the connections where made. Item doesn't include original packaging but will be double boxed for shipping. This unit was owned by my father in law since new. He has passed and I'm selling for that reason. I'm really enjoyed listening with him but this is above my level and I don't want it to sit in a closet unused. I believe i remember him replaceing/upgrading the 3 tubes right after purchasing it but not positive. I'll answer all questions you have.
