  • permalloy input transformer for balanced access, Philips' 12AT7 for high-gain amplification, and Russia's SOVTEK 2A3 direct heating transistor for boosting amplification.

  • Two U.S. Philips 12AT7 do the second stage high gain amplification, two Russian SOVTEK 2A3 directly heated triode do push amplification

  • Two high-performance driving transformer and push tube 2A3 do low distortion, low impedance 600 ohm output driver 805

  • Four Early Chinese 5Z4P do Tube high pressure buffer,use the heat tube's delay characteristics do power supply for precious 805,

  • All DC power supply 805 and 2A3, 2A3 filament and high-voltage also designed voltage stabilizing circuit

  • 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

  • Circuit uses four high gain amplifier promote strong

Equipment match Description:
  • Input impedance 100 ohm (unbalanced) 600 ohm (balance), the machine is suitable with sensitivity greater than 85DB bookshelf or floor speakers. For a lot of apron polypropylene cone speakers, power shelves, England speaker has excellent overall performance,

  • Use this machine driving rain early ATC20 Harbeth M40 Klipschorn have exhibit superior quality.

  • The machine output impedance of 0 ohm 4 ohm and 8 ohm, 6 ohm speakers should be connected to the output terminal 8 ohm, maximum use of the output transformer secondary windin
