Purchased New Old Stock with less than 30 hours on the tubes and the unit. These tubes alone are a $200 upgrade from Schiit. The unit and tubes aren’t even broken in. - Going in a different direction with my system. I will ship double boxed with Original Box and very well packaged. Like new condition owned for about a week. New versions of this preamp with these tubes $1100 + tax. NOTE: one of the tubes had a missing keyed base. I replaced it with a new base, see photo. Zero effect in performance. Includes oem power cord and remote
