                    Key Features

                    • The Bias Select switch is engineered with 3 bias settings for 4 different output tube
                    • Compatible with KT88, KT120, KT150 and KT170 output tubes
                    • Bias Select switch is easy to use, change on the “Fly” so you can hear the difference
                    • Auto Bias is safe, consistent and settings are always perfect
                    • Class A power is fast for a more lively, immediate response to your music
                    • 4, 8 & 16 Ohm taps gives you options for your speaker preference
                    • Dual Mono gives you less cross talk and better stereo imaging
                    • Choice of high quality gold plated Single Ended RCA or Balanced XLR connectors to suit your needs or cable preferences
                    • True transformer differential balanced XLR inputs for the best noise rejection
                    • Independent Left and Right ground switches on the XLR balanced inputs to eliminate ground loops and hums
                    • No Negative Feedback design does not modify or compress the musical signal
                    • Large custom Toroid is higher voltage for increased performance and lower noise
                    • Global mains power supply can work all over the world
                    • Provides plenty of gain for your system
                    • Push-Pull/Ultra Linear circuit design provides lower distortion, more power, and a better performance out of your tubes
                    • Low noise levels allow really dark black quiet musical passages
                    • Non-inverting polarity retains the same phase as the input (so your trumpets blow and don’t suck)
                    • Gold pin sockets are more reliable because gold doesn’t oxidize when it heat cycles
                    • Matched quad KT150 output tubes retain the stereo balance and lower noise
                    • Elegantly designed, heavy duty 14 &16 gauge zinc plated steel enclosure to accommodate the extensive grounding scheme
                    • The optimized frequency response provides the best musical range to benefit the natural harmonic structure of the instruments
                    • All fuses are easily accessible
                    • Each unit is hand built “Made in the USA”
