It was 1979 that we produced a single ended power amplifier with 300B.   
Since then we made every effort to refine this original model. Advanced cicuit and selected 
parts result in a natural presence and dynamic  sound reproduction. 
We recommend using very efficient loudspeakers of more than 90dB and Max input lass than 50 watt.
