ROGUE AUDIO Stereo 90 With Super Magnum Upgrade Plus Extra Set Of Tubes "Very Nice Tube Amplifier" Like New" Low Hours"

Up for Sale is a ROGUE AUDIO Stereo 90 Tube Amplifier with the "Super Magnum" Upgrade done by Rogue Audio back in late January of 2018. Since getting the amplifier back from Rogue it has been used very little. Low hours of use and is in like new condition with all the factory accessories included: owners manual, biasing tool, power cord, factory boxes with packing material and a complete extra set of tubes: (4) Electro-Harmonics KT-88, (2) EH 6SN7 and (2) SOVTEK 12AX7 that were used before the (4) new KT-90's and the other (4) new tubes were installed as part of the "Super Magnum" upgrade. This is a great all around sounding amplifier from top to bottom, with plenty of bottom end power to boot and was awarded the TAS Editors Choice award in 2013. You can either run this tube amplifier in triode or ultra-linear mode with the flick of a switch located on the back of this amplifier depending on your sound preference and power output that's desired. Total investment including the super magnum upgrade was close to $3300. *** Note:> I will only ship in the USA. *** Please buy with confidence from a trusted long time Audiogon member with perfect feedback. *** No Trades. ***  Thanks!
