Description:The Cyber100 signature delivers a taste of luscious tube sound compared with solid state gear at the same price. This tube amp is mothered by M100plus, the highly reviewed push-pull set Internationally, which has been our best selling integrated tube amp since the company was found in 1994. It now comes with 5 input prs, remoteable selector switch and volume pot. It uses low negative feedback with choke design, so no further bias regulation would be needed for optimal tube regulation and sound. At 40 watts, the Cyber100 signature also comes with a power transformer and circuitry that is over spec and built to easily accept the extra current of the KT88. The EL34 can also be used.Integrated tube amp (EL34 push-pull, 40W)Specifications:Control Functions: Remotable,Volume, Select, Power On/OffPower Output: 40 watt, RMS 1kHzTotal Harmonic Distortion: less than 1%(10watt, 1kHz)Frequency Response: (-3dB points at 10 watt) 6Hz-50kHzInput Sensitivity: 260mVInput Impedance: 50k ohmsOutput Impedance: 4 , 8 ohms.
