Basic 2 box, tube ( 2- 12ax7 ) phono preamp. Comes with 2 Gold Aero 12ax7s. Good basic tube phono preamp. I don't know what the gain is but only works with moving magnet cartridges or high output mc. It is very responsive to upgrades in tubes and power cords. I found it worked well with the Brimar and Telefunken 12ax7s and Shunyata Platinum Plus pc I used with it. In excellent working condition. Good cosmetic condition. It's no looker, just 2 black boxes connected by umbilical cord. IEC jack for power cord. Stock power cord included. I have perfect feedback on Audiogon and E-Bay under BillyBenBilly.
