Product Description

Quad II Forty mono monoblock power amplifiers shares the sophisticated elegance of the original Quad II from the 1950's, but its been updated, to be more refined, with an excellent build quality and finish.

The first significant improvement is with the chassis, it is larger to accommodate the new larger components, which are wired by hand, following a similar topology to the original.

Input Valves

The modern listener demands more power than the fifteen watts output of the original Quad II. The new Quad II-forty has used larger output valves, KT88s replace the KT66s and the power supply is more sturdy, utilising a 5U4G rectifier valve. The input valves on the new Quad II forty are so good that they are military grade 6SH7s instead of the previous EF86s.

Lifetime Use

All Quad products are expected to last a lifetime, or even longer. Many Quad buyers are still using their original amplifiers, that were built over half a century ago, and they still derive immense pleasure listening with them. This new amplifier from Quad, is no exception, it has the ability and quality to last 50+ years. With Quad products, if you undertake regular servicing and you give it the care it deserves, you can expect these amplifiers to perform for many decades to come.

Elegant Finish

Supplied in the Lancaster Grey finish pictured. A perfect match paired with the Quad QC24 valve pre amplifier and/or Quad ESL 2812 or ESL 2912 speakers.
