Open box 14-days return – slight mark to ONE unit as pictured
Designed by Tim DeParavicini, the Quad II-Eighty takes inspiration from the original Quad II amplifier. It is an 80-Watt mono power amplifier following in the tradition and philiosophies of Peter Walker. The output section consists of 4 KT88 valves running as two pairs in push pull with the hallmark Quad topology of partial cathode loading in the output transformer.
A Truly Iconic Amplifier
Designed by Quad founder Peter Walker, the truly iconic Quad II helped to define the modern concept of high-fidelity sound in the 1950s. Quad has kept the legend alive with the current Quad II classic, a faithful reproduction of the original valve monoblock with build quality and aesthetics lovingly updated for the modern era. The new version takes this a step further, with the development of additional, pre, power and integrated models.
The Quad II Series circuit design is the work of Tim de Paravicini, a man widely acknowledged to be the UK’s foremost valve amp designer. His design is faithful to Peter Walker’s Philosophy of cathode loading onto the same output stage and fundamental simplicity of design, ensuring the new amp delivers the same wealth of detail and exquisite tone as its famous predecessor.
