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. The ECC83 Retro retains the classic Mullard crunch and provides a harmonically rich and detailed sound with an excellent 3 dimensional midrange response.

The Harma ECC83 Retros outstanding feature is its smooth linear midrange response and extended frequency response so you get smooth warm overdrive with tight fat punchy lows.

The Harma EL34-Retro is based on the famous Mullard EL34 XF2 design and has a number of important features over standard EL34 types.

The grids of the tube use a block construction this enables the valve to provide smoother output and eliminating odd order harmonics.

The valve has a slight midrange forwardness giving the sound a full rounded tone when distorted or overdriven.
