AA SE 18

“I have to admit – I do not really understand the “negative feedback” philosophy completely, but as long as it sounds like Audio Alto tube amplifiers – that is my hi-fi way too.” C. M.

A single ended amplifier with an output power of 2 x 18W the SE18 is aimed at lovers of music that is reproduced without negative feedback. Audio Alto’s signature circuit design and layout helps keep distortion to a minimum while increasing damping factor. The single ended output stage configuration allied to specially designed toroidal transformers lets the listener enjoy the music in the most natural way.

Source selection and other functions are controlled with push buttons or via remote control, with switching of inputs and outputs through high quality relays. Power supply management and turn-on delay is performed by microcontroller and there are separate FET-stabilized supplies for the input and output stages. Valve filaments in the input and driver stages are also DC regulated and stabilized. A stereo jack on the front panel allows for headphone listening.
