Linear Tube Audio ZOTL Ultralinear Amp PRICE DROP!

Purchased new in 10/18 this amp is in perfect condition with about 14 months usage (the rest in storage during move) in a non smoking environment.  Rarely seen in the secondary market, these David Berning designed amps are considered among the finest, most musical amps being made today.  Selling because new listening room required a downsizing of system and budget.  I have outfitted the amp with expensive NOS Telefunken 12AX7 and 12AU7 tubes, but I'll also include two Brimar Cryo treated 12AU7 tubes ($88 ea new), two Amperex Bugle Boy 12AX7, and a full set of replacement RCA driver tubes that came with the amp.  Please see Linear Tube Audio's website for more info and links to the great reviews this amp has received.
