MC368-BSE Vacuum tube INTEGRATED AMPLIFIER Specification :Input Voltage:200mvOutput Impedance:4Ω,8ΩDistortion Factor:≤1%Iutput Impedance:100KPower Dissipation:250WSignal-to-Noises:89dBOutputs:2 GroupsInputs:4 GroupsOutput Power:Ultralinear 75W×2 Triode 40W×2Frequency:15Hz-55KHz ±1dBVacuum Tubes:KT90×4,6SN7×2,12AX7×2Size of outer carton:55L x 48.5W x 39H(cm)gross weight:33kg Redesigned to the circuitry of MC368-B to make frequency wider, signal-to-noises rate higher and the sound is more natural. Improve the quality of the main components and use imported coupling capacitors and the electrolytic capacitors are branded as Panasonic and Philip. Powerful resistors are changed to American wire-wound resistors and make the signal amplification to noninductive resistors. The Kt90 tubes for this amplifier are manufactured on site to ensure a good fit with the rest of the amplifier and to compensate for the shortfall of high quality KT90 tubes on the market. Its power, dynamic are better than KT88, 6550. An additional bonus for the end user is a stylish remote control made from black cast aluminum.and Japanese ALPS potentiometer Customer Reviews
