MM/MC phono preamp with factory packaging and tubes. Small footprint perfect for limited space. ALSO comes with heavy duty Swagman Labs fully linear 18v toroidal dedicated power supply, specifically made for this preamp. Brings it to another level, compared to factory wall wart. I am original owner. Kid and smoke free in acoustically treated environment. NOTE: grounding point was modded by me for truly locked and tight ground attachment. A HUGE improvement over factory design, which allowed noise.
