Quad II Eighty Valve / Tube Amplifier, KT88, 80W - Stereo Pair
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 philosophies 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.
Phonostage's thoughts on the QII Range...
I am a definite fan of this Quad valve amplifier range. I sometimes think back to dashing out at short notice, trying to grab a set of Quad IIs with the preamp (before someone else did) after we spotted them cheap in the classifieds!! I bet we paid no more than a couple of hundred quid for a full set!! Those were the days eh... Well am pleased to say they are not over - not completely anyway. Tony, Phonostage Audio
This range of Quad amplifiers are superb. Better in fact than the originals in most respects with some faithful to the original, some with more power, larger power valves, more robust power supply, more refinements and reliability, improved components (such as military grade preamp valves) - and safer!! These amps are designed to last a lifetime.
