The heart and the soul of the amplifier is the unique use of classic EF86 pentode with a gain thats 50% higher than the hottest 12AX7 this delivers its own distinct voice.
The EF86 Mazda excels in guitar amplifier applications due to the design of the Russian Mazda EF86 having a lower output impedance; the result is 10 % more gain when compared to other modern and new old stock EF86s.
The Harma ECC83 STR has exceptional note clarify with improved definition on the clean tone and extra bite and rich harmonics when overdriven. The valves overdriven characteristics by providing a warm sustaining sound with plenty of upper harmonics.
The REC KT66 Relic is a meticulous recreation of the famous GEC Osram KT66 and follows the original military specification KT66/CV1075.
The REC KT66 Relic 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 CV1075.
The REC KT66 Relic 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 will supply the famous blues breaker tone of tight punchy lows and clear dynamic highs. The valve has more clarity and bite at the top end with a supreme warm midrange tone resulting in rich harmonics when overdriven.
These are simply the right valves to power this remarkable amplifier and takes sound back to it's sonic roots.
We use an original American Philips 5U4GB as these provide the correct rectification with no reduction in B+ voltage unlike many of the modern 5U4GB on the market today.

1 Selected and balanced Harma ECC83 STR in V2
2 Selected and matched REC KT66 Relic
