This Classic Marshall kits is designed to give you as close as possible to the vintage Mullard GEC KT66 legendary guitar tone.

This is done by using modern day production valves that are traditionally voiced and then getting the sonic improvement that Cryogenic treatment brings to the valve. The Cryo treated valves have a smoother distortion with more detail and clarity. The valve has more bite and better focus and they produce a sound that is only attainable by using very expensive new old stock valves.

The Harma ECC83 Retro Cryo retains the classic Marshall crunch and provides a harmonically rich and detailed sound with excellent 3 dimension midrange response. This valve has a traditional British voiced sound and the Cryo treatment improves this valves sonic signature and gives exceptional depth in the midrange. The Cryo treatment enhances the smooth linear midrange response and gives a smooth warm and punchy midrange with excellent clarity and tight fat punchy lows.

The Cryo treatment also improves the valves overdriven characteristics providing a warm sustaining sound with plenty of upper harmonics. This captures that classic vintage Marshall sound better than all the other ECC83/12AX7 that I have tried.

The REC KT66 Relic Cryo is a meticulous recreation of the famous GEC Osram KT66 and follows the original military specification KT66/CV1075.

The REC KT66 Relic Cryo has a number of special features such as a gold plated grid wire with carbonized screen grids. The valve has 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 Style Dual ring getter which are located at the bottom following the original design. GEC Style Grey welded anode plate, GEC Style Dual Horizontal anode slots. These valves are all specially burnt in and selected to the same current specifications and current range of the Original GEC KT66 CV 1075. The valves then go through our burst testing process.

The REC KT66 Relic Cryo is as close as you can get to the original British made GEC KT66 in terms of look and performance. No other KT66 on the market today gets this close

These are simply the right valves to power this Marshall especially if you want to recreate Clapton's Famous Bluesbreaker sound and take the governors amps back to its sonic roots.
