New Audio Alto AA 4AI Integrated Amplifier.

Audio Alto writes: "The new Audio Alto AA 4AI integrated amplifier with special vacuum tubes is ready! It took quite some time to develop and prepare this special integrated amplifier that uses 1960-1970 (NOS) tubes. It provides 4 analog inputs, one (as an option) can be a MM/MC turntable input. 

All parameters of the tubes, such as voltage, current, are time-optimized to ensure a long service life (a digital display of the hours of use is also included)."
