SONATAS-T (Full Tango version) 40W+40W Stereo Valve Tube Power Amplifier

Audio Experience SONATAS-T  is a 40W + 40W Stereo Valve Tube Power Amplifier.
It uses one matched pair of EL34 power tubes and UL working status to provide RMS 40W adequate output for most of the Hi-End Speakers to ideal performance. Moreover, It use the high quality output transformer ( TANGO . made in Japan).
Huge dynamic range, both the beautiful tone color and wonderful rhythm , ultra linear circuit of the valve tubs power amplifier designed for the DVD - Audio and SACD source in the New Century. uncanny natural flowing heart-stirring sound that matches any other ultra-Fi products on the market .


   The input stage is 12AT7 SRPP direct coupling to 12AU7 driver stage , The driver stage use high quality capacitors to EL34 power tube , The EL34 work at P-P UL mode to driver TANGO U-405 high quality output transformer , The U405 output transformer has very low Insertion Loss 0.29dB only.  ( Many tube power amplifier in Hi-End audio market , Their have the output transformers is over 1dB Insertion Loss . only about 10% very high price tube amplifier use under 1dB Insertion Loss of output transformer ) . The output transformer has low insertion loss is very important , the best of the best is 0 dB Insertion Loss , The output transformers for High End tube amplifier need under 1dB  Insertion Loss . The Insertion Loss over 1.5dB output transformer will lost many low level music.

   The bias adjust of power tube is very easy , all bias test point and bias adjust at top of amplifier , you not need open the amplifier for adjust the power tube bias.

   The components ,  NFB value , tube type , circuit all select by listen test.
