The EV55SE Valve Integrated amplifier is the first vintage tube electronics product from EKCO. Designed as a Class AB Push-Pull amplifier, the EV55SE offers a choice between 28Watts RMS per channel at Triode mode and 55Watts RMS per channel at Ultra-linear mode. It comes with five (5) RCA inputs and A/B option selective loudspeaker outputs into 8 Ohms, controllable via the included remote control. Its chassis is made of protective grilles finished with high-temp black paint protect the valve tubes while the sides of the chassis are fitted with matched pairs of handcrafted solid wood panels (deep Louro Preto) in piano gloss finish adding to the classy and elegant feel of the valve amplifier.

Technology 

Element
The KT88 is a beam tetrode vacuum tube that fits a standard eight-pin ceramic octal socket; designed specifically for audiophile amplification, it is one of the most popular tubes in its class and is capable of handling very high plate voltages up to 800V. A pair of KT88 in push-pull Class AB fixed bias has a maximum output of up to 55W at low distortion.

Amplification
Working in Class AB Push-Pull Operation, the EV55SE is fitted with a switch that allows it to change from Triode mode, producing 28W RMS per channel, into Ultralinear mode producing 55W RMS per channel. In Ultralinear mode the output impedance is lowered to offer a damping factor about twice that achieved with a triode, distortion is lowered to approach the ultimate achieved with a triode tube, and the power output is increased to near the maximum available from pentodes.

   

Variety
The EV55SE comes with dual speaker output options tailored for audiophiles who prefer to use more than one pair of loudspeaker setup combination for their system, or to facilitate bi-wiring. It also includes a special remote that allows volume control anywhere inside a room.

Elegance
Protective grilles finished with high-temp black paint protect the valve tubes while the sides of the chassis are fitted with matched pairs of handcrafted solid wood panels (deep Louro Preto) in piano gloss finish adding to the classy and elegant feel of the valve amplifier
