2x60 W Integrated Tube Amplifier, in a dual Push-Pull pentode configuration operating in Class A up to 40 W, thanks to a special automatic biasing and screen regulation circuit, original and exclusive to Ars-Sonum. Specifically designed to authoritatively handle the highly variable impedance curves of today's loudspeakers (from 3 - 12 Ohms), without compromising overall dynamics or the critical current delivery in the low frequencies. This is the most versatile and powerful integrated amplifier in our history, redesigned without limits for this MAGNUM edition with components of a superior generation.
