Product Details:
The combination of electronic tube and field-effect transistor makes this H-80B III not only have the sweet and moist taste of an electronic tube amplifier, but also the speed and strength of a transistor, combining rigidity and softness, creating a natural blend The sound quality is extraordinary Elegant and dignified appearance, deeply loved by Audiophiles.
Matisse preamp circuit, filament stabilized power supply, minimizes noise floor to the greatest extent possible.
Electronic tube rectification makes the sound smoother
The transformer and rectifier board are installed separately in a section, away from the amplification part Greatly reduces interference.
The voltage amplification adopts 2SA1145 \ 2SC2705, and the driving adopts 2SA940 \ 2SC2073, combined with 4 pairs of Hitachi used power transistors.
Switching between 4 sets of input signals.
The preamp and amplifier are independently designed, with a reasonable internal layout and a neat and beautiful appearance.
Thin steel plate chassis, treated with frosted spray painting process, metal knob.
The output end adopts a high current relay delay protection horn, which has functions such as on/off static noise, midpoint potential drift, and overcurrent protection.
Gold plated RCA+anti-oxidation gold plated terminal post.
27 type sealed potentiometer.
Imported polypropylene coupling capacitors from WIMA, ERP, and other companies in Germany.
300W toroidal transformer, with sufficient power and low radiation.
Built in large aluminum alloy radiator for fast and effective heat dissipation.
Imported fast rectifier bridge, 4 10000uf filter capacitors
