Quad II Forty Mono Valve Power Amp (Pair)

Quad II-Forty Mono Valve Power Amp (Pair)

Quad's QII (or 'Quad 2') series is based on the original Quad II amplifier, built by the company's founder Peter Walker in 1953, but now seeing the integration of finer components and materials, more intricate yet effective circuit integrations and a more precise manufacturing process. The QII series features some of the most refined sounding valve pre/power combinations on the market today, retaining the genuine heritage and craftsmanship that Quad has preserved over 80 years of designing and engineering quality hifi. 

The Quad II-Forty features much of the same elegance and commitment to sound quality that was found with the original Quad II, launched in the 1950s, but sees the implementation of a larger chassis capable of housing the larger hand-wired audiophile components within. Now capable of a higher output, the Quad II-Forty is the ideal solution for the discerning analogue music listener. 

The Quad II-Forty uses larger output valves and comprises of upgraded tubes from the KT66 to KT88. These quality valves, combined with the robust power supply utilising a 5U4G rectifier valve. The input valves are to military specification 6SH7s, an improvement over the EF86s.
