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
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
