Audio Experience YSA-300B  6W x2 Stereo Valve Tube Power Amplifier Audio Experience YSA-300B  is a 6W x 2 Stereo Valve Tube Power Amplifier. I   The power amplifier use one 300B power tubes work at SET Single Ended Triode configuration status to provide 6W adequate output . Moreover, It use the high quality output transformer ( TANGO . made in Japan).    The input stage use Lundahl (SWEDEN) high Mu cores (Mu metal) input transformer to Western Electric 328A Driver tubes . WE320A driver tube use Teflon Film coupling capacitor to 300B power tube . The 300B tube work at SET Single Ended Triode mode to driver TANGO U-808 high quality output transformer , The TANGO U808 output transformer has very low Insertion Loss 0.5dB only.  ( Many SET tube power amplifier in Hi-End audio market , Their have the output transformers is over 2dB 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.      This power amplifier case structure and parts arrangement are perfect, the signal path is directly and shortly connected. Great heat dissipation, an anti-shock and anti-RF function to guarantee it works at a very stable status. For sure, this machine is produced by point-to-point ( use FURUTECH  α(Alpha)-Conductor---The fine PCOCC Conductor wire) methodology.  Features Lundahl (SWEDEN) High Mu cores Input Transformer Western Electric 328A drive tubes Teflon Film coupling capacitor TANGO U808 Output Transformer TANGO EC-5-250S Choke  R-Cores Power Transformer F&T ( made in Germany ) electrolytic capacitors for power supply RCA and Balanced (XLR) input  BEST OF THE BEST 300B SET SOUND            Specifications Output :  6W +  6W (8 ohm) Input :  RCA , Balanced (XLR) Input Impedance :  25K ohm Frequency Response at 6W :  20Hz ~ 25K Hz ( +0/-0.5dB )    Input Sensitivity :  1.4V / 6W Output impedance : 8 ohm / 16 ohm                                           S/N Ratio: > 103dB (IHF-A Average rate),   >86dB (Flat Average rate) Phase Mode : Normal Construction: Copper Plated Chrome and High quality aluminum Tubes Required: WE328A x2 , 300B x 2, 5U4G x 1 Dimension: 430mm x 340mm x 230mm (W x D x H) Total Weight: 15kg Power Source: 110-117/220-240V,50/60Hz 3 year warranty ( not include tubes and ship cost ) The Amplifier Include : Box , Power Cable , Manual , All Tubes.
