An incredible soundingvacuum tube stereo amplifier--professionally assembled and tested--for aboutthe same price as many kit amplifiers. Full, deep, rich bass. Extended highs. Ultralinear circuit uses an extra set ofwindings in the output transformers. This gives the smoothness ofSET amps with the power and dynamics of pushpull design. And lowerdistortion than both. The Audio Nirvana EL84 uses the two most popularvacuum tubes of all time. The EL84 (6BQ5 or 7189) power tube. The 12AX7 small signa...l tube. 10 watts per channel--all youneed with the highest quality high efficiency speakers. If you needmore power than this, you don't have great speakers. Can be operated withor without the included 'cage'. Includes two sets of knobs--silver orblack. 4 ohm and 8 ohm gold plated metal terminals. Twoinputs with selector. Dual voltage: 115 volts or 230volts. Parts are chosen for the best possible sound quality--notbecause we want to impress you with 'boutique' names. Each amplifier isbeautifully hand assembled and tested. To maintain the superb sound, there are no adjustments to be made--ever. Self biasing, no AC or DCbalance to adjust. And made with the fewest parts possible and bestsounding tubes. This is a 'straight power amplifier with a volumecontrol'. There is NO preamplifier inside, just a passive linestage. A 10, 000 preamplifier can't sound better than no preamplifier atall. No separate preamp is needed. Just connect any 'line level'source, like CD, DAC, Tuner, Tape directly to the A or B input. If you dowant to use phono, you will need an 'outboard' phono stage. We can tellyou where to get a great one for under 200.FeaturesEL84 (6BQ5 or 7189) Ultralinear vacuum tube stereo amplifier with four EL84 and two 12AX7 vacuum tubes.Conservatively rated at 10 watts per channel (average listening level for our Audio Nirvana full-range speakers is 110 of a watt).Each amplifier is individually hand wired.No integrated circuit chips.Transformers wound in our own factory.Polished stainless steel chassis.Brushed aluminum face and back plates.Two pairs of silver and black knobs included.4 and 8 ohm gold plated speaker terminals.Accepts two line level inputs.Voltage selector for 115 or 230 volts.Excellent build quality will ensure years of reliable service.SpecificationsINPUT IMPEDANCE: 100K ohm (RCA)OUTPUT IMPEDANCE: 4 ohm - 8 ohmOUTPUT POWER: 10W into 8 ohms, CLASS ABDAMPING FACTOR: gt3FREQUENCY RESPONSE: 20Hz-20KHz -1dBT.H.D.: lt1 20Hz-20KHz (REF.
