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.

The KT66 Relic is a premium high quality audio grade KT66 that is based on the famous GEC design. Now owners of the Original and legendary Quad 11 power can obtain an authentic looking and specially selected KT66 for Quads.

The KT66 Relic is a premium high quality audio grade KT66 that has a number of high grade features which set this valve apart from other KT66 on the market.

The valve features a thick glass envelope with a welded anode plate to prevent microphonics and rattle. The anode plate uses a laminated alloy which helps heat transfer under overload conditions. The grids of the valves use gold grid wire and the grid rods are made from copper which is the best materials to use. The valve uses GEC ring getter which is located at the bottom following the original design.

These valves are all specially burnt in and selected to the same current specifications and current range of the Original GEC KT66 CV1075. The valves then go through our burst testing process which involves a series of varying timed electrical signal bursts. This runs the valves under the same stress conditions that they will meet in your amplifier. All out put valves are then dual matched by us on current and gain. This will ensure that you get the best selected KT66 available anywhere in the world. TheKT66 Relic comes with a 6 month warranty form the date of purchase.

The KT66 Relic displays very smooth open and dynamic sound with excellent balance. The bass response had rock solid bass note definition with superb speed and clarity. The midrange is very vocal and smooth with plenty of extended range. The top end response is easy to listen to with a very musical sound which is very smooth and detailed.

The sound of this valve outperforms many other KT66 on the market today. When you factor in the Special low price of these then the KT66 Relic from REC has no competition.

We use a Siemens EF86 RU with the solid pimple screen anode which date from the mid-1980s. Superbly constructed the Siemens EF86 valve is very well balanced with superb image and detail and drives the Quad really well. To complete the package we us a Harma GZ32 that has been designed around the Original Mullard GZ32 with a more compact size but still retains that beautiful shouldered bottle thus retaining the Classic Quad look
