-Quad II Eighty Monoblock Power Amplifier Pair - Product Description
A modern classic and designed by valve supremo, Tim DeParavicini, the Quad II-eighty is much more than a homage to the Peter Walker classic - it's a complete reinterpretation of the philosophy. Using 4 x KT-88s and a similar cathode coupled output, the lineage is clear to hear and see, but with such huge dynamic headroom, this amp is faster and with more control than any previous model.
The latest addition to the Quad Valve power amplifier series is the long awaited Quad II-eighty amplifier. The Quad II eight is the perfect partner for the Quad ESL speakers, the Quad II-eighty is not merely a nod in the direction of retro styling, it's a modern high performance amplifier designed by one of the most famous tube-amplifier designers in the world (Tim De Paravicini) using more than a little inspiration from the original Quad II amplifier.
The Quad II-eighty Valve Power amplifier is an 80 watt mono amplifier following in the tradition and philosophies of Peter Walker. The Quad II-eighty 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. This method reduces distortion when compared to the usual Ultra Linear or triode methods, however, it does require a greater grid driving voltage. This is achieved, again in true Quad fashion, using a balanced pair input stage.
The Quad II-80 output transformer has been designed to improve high frequency performance and accurately balance to two push pull halves. Also the transformer has been designed to make sure that full output is realised at the bass frequencies down to 20Hz. Each output valve has its own cathode resistors to provide reliability and self matching. The screen grids of the KT88 valves are run from a lower voltage, again for good reliability. Overall the Quall II eighty valve power amplifier has a total of only 16dB of feedback providing good stability into virtually any known loudspeaker and especially the famed quad electrostatic loudspeakers.
