Since Peter Walker founded Quad in 1936, all Quad products have displayed originality in design and outstanding audio excellence. A world leader in audio amplifier and electrostatic speaker design, Quad has been recognised by awards from around the world including the Queen's Award for Technological Achievement in 1978 the only one ever presented to an audio hi-fi equipment manufacturer. It is hard to believe that the legendary Quad 11 was discontinued in 1970, yet my own Quad 11 still outperforms many high end amplifies some 45 years on. Our kits use the best current production and NOS valves to help you get the best sound out of these legendary amplifiers.
A modern integrated amplifier which incorporated the legendary Quad 11 output section.

The Harma ECC83 Retro is a true sounding recreation of the famous Mullard ECC83. This valve replicates the warm detail and harmonically rich midrange that made the Mullard sound so famous.

This captures that classic vintage Quad sound better than all the other ECC83/12AX7 that I have tried.

The Harma KT66-Retro is a meticulous recreation of the famous G.E.C Osram KT66 and follows the original military specification KT66/CV1075. The Harma KT66 Retro has a number of special features such as a gold plated grid wire with carbonized screen grids. The anode plates use a tri-alloy plate structure with gives exceptional performance and sound quality. The Harma KT66 Retro shares the same anode design and bottle shape as the original it has the top mica supported with spacers on the 4 corners to prevent rattle and is made with a brown replica base just like the G.E.C.

These will supply the famous Quad sound of tight punchy lows and clear dynamic highs. This valve has a richer clear treble response which has more clarity and detail at the top end. The bass end has more weight and slam and is well focused and crunches with more dynamics than the standard valve.

The Harma KT66 Retro is as close as you can get to the original British made GEC KT66 in terms of look and tone.

To replace the 6922 we use an original Philips ECC88 as Sound wise; this valve has it all, speed & dynamics with plenty of deep musical bass definition. Its transparent and warm midband excels on vocals and strings. The Philips ECC88 is an Audio bargain as you get all the Mullard sound at super low price
