Model: 300B SET

Class A Single Ended Triode vacuum tube stereo amplifier with deep, powerful, extended bass and highs that extend to the limits of human hearing.  Together with the traditional smooth and detailed SET midrange, this is the best sounding amplifier we have heard to date. 

The Audio Nirvana 300B SET uses an enormously powerful toroidal power supply, protected in a real potted case (not a dummy one, as many companies use).  Transformers are massive and are hand wound in our own factory.  The amplifier weighs approximately 56 lbs (25 kg).  4 ohm and 8 ohm terminals. Three inputs with selector.  Dual voltage:  115 volts or 230 volts. Parts are chosen for the best possible sound quality--not because we want to impress you with 'boutique' names.  Each amplifier is beautifully hand assembled and tested.  To maintain the superb sound, there are no adjustments to be made--ever.  Self biasing, no AC or DC balance to adjust.  And made with the fewest parts possible and best sounding tubes currently available.
