QUAD QII-Eighty
Power Amplifier 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.
