Rogue magnum 66 with built in MM/High output MC phono stage. Uses 2 12au7 and 4 6922 tubes which are included. Separate power supply, original packing and manual also included. This is a great sounding unit and was only replaced and bested by a unit costing over 5 times the original list price. Amazing how close this preamp held its own compared to the more expensive unit. Well cared for and with the exception of a few tiny nicks is in excellent shape. Used in a non-smoking household devoid of pets and children. Was checked out and given some minor tweaks and a workup around two years ago by Mark O'Brian at Rogue audio.
