UNISON RESEARCH PRELIUDIO AMPLIFER INTEGRATE TUBES HI FI STEREO KT88 ECC82 TUBES

UNISON RESEARCH PRELUDE TUBE INTEGRATED AMPLIFIER HI FI Unison Research Preludio has a toroidal transformer . The anode power supply for the Prelude has a much higher capacity than a normal power supply. preamp valve and drivers are current using the c. the anode of the power stage valves. The voltage is regulated by a dedicated power supply which uses a part of the energy otherwise dissipated. This also allows an improvement of the general system, optimizing space and reducing heat. Each of the Prelude channel has a preamplifier stage, a power stage and an output transformer *. And preamp stage potenzadipendono by a double triode ECC82, a valve that keeps linearity and eliminates harmonic distortions. All the amplification stages are tube and operating in pure class A . So the first stage constituted by a triode ECC82 operating as an external cathode of the ring to practically zero-feedback feedback. Equipped with a low impedance output for active subwoofer , with volume potentiometer. The outputs are designed for both channels via two large gold plated connectors suitable for any type of cable, allowing you to connect speakers with a nominal impedance of 8 ohms. stereo2000.it
