Features:
Permalloy input transformer enables balanced access, utilizing Philips' 12AT7 for high-gain amplification, and Russia's SOVTEK 2A3 direct heating transistor for boosting amplification.
The second stage high-gain amplification is achieved with two U.S. Philips 12AT7 tubes, and two Russian SOVTEK 2A3 directly heated triodes are employed for push amplification.
Two high-performance driving transformers, along with push tubes 2A3, ensure low distortion and low impedance (600 ohms) output drive for the 805.
Four Early Chinese 5Z4P tubes serve as a tube high-pressure buffer, utilizing the heat tube's delay characteristics for power supply to the precious 805.
All DC power supplies for 805 and 2A3 are designed with voltage stabilizing circuits. Additionally, the 2A3 filament and high-voltage circuits feature voltage stabilizing designs.
Two 400W power transformers provide a substantial power margin. The output transformer adopts a large open structure with vertical installation, delivering 50W of power. This transformer is specially designed for A2 class 805 straight tube applications.
Equipment match Description:
Input impedance: 100 ohms (unbalanced), 600 ohms (balanced). The machine is compatible with speakers having a sensitivity greater than 85dB, whether bookshelf or floor-standing. It excels with a variety of cone speakers, including apron polypropylene cone speakers and power shelves. It particularly showcases outstanding performance with English speakers.
This machine has proven its superior quality when driving various speakers, including but not limited to Rain, Early ATC20, Harbeth, M40, and Klipschorn.
The machine's output impedance is selectable at 0 ohms, 4 ohms, and 8 ohms. When using 6-ohm speakers, connect them to the 8-ohm output terminal for optimal performance. Make sure to maximize the use of the output transformer secondary winding for the best results.
