Features： 1.Two permalloy transformer do first-class pre-amplification, the input transformer amplifier gain can control,small distortion, without feedback circuit and Complete True balanced input 2.TWO U.S. GE's 12AT7 do the second stage high gain amplification, two Russian SOVTEK 2A3 directly heated triode do push amplification, using Danish JENSEN Copper foil oil-immersed capacitance do resistance capacity coupling 3.Two high-performance driving transformer and push tube 2A3 do low distortion, low impedance 600 ohm output driver 805 4.Two latest version of Shuguang PSVANE 805T doing power amplifier stage, can easily answer 120W anode power 5.Four Early Chinese 5Z4P do Tube high pressure buffer，use the heat tube's delay characteristics do power supply for precious 805, 6.All DC power supply 805 and 2A3, 2A3 filament and high-voltage also designed voltage stabilizing circuit 7.Two 400W power transformers, power margin big. Output transformer for large open structure vertical installation, power 50W. This is a specially designed for A2 class 805 straight tube of special transformer 8.Circuit uses four high gain amplifier promote strong Equipment match Description: Input impedance 600 ohm (unbalanced) 150 ohm (balance), the machine is suitable with sensitivity greater than 85DB, bookshelf or floor speakers, push hard for a lot of apron polypropylene cone speakers, power shelves, England speaker has excellent overall performance, I use this machine driving rain early ATC20 Harbeth M40 Klipschorn have exhibit superior quality and world famous machine can do comparison. The machine output impedance of 4 ohm and 8 ohm, 6 ohm speakers should be connected to the output terminal 8 ohm, maximum use of the output transformer secondary winding.
