This machine is the improvements made on the basis of the third generation Danji, elegant formal appearance modeling, grade skills.
● Silver 1.2mm thick brushed stainless steel craft box.
● Advanced wrinkle paint process cattle cover.
● large metal knob cellular machine feet.
● high-grade gold-plated signal RCA terminal.
● sturdy gold-plated 4 ohms, 8 ohms power output terminal.
● precious red cherry side trim panels.
● blue power indicator tube.
● preamp tubes Properties:
6N6T: high mutual conductance (S = 11mA / V), in the amplification factor (u = 20) and low internal resistance (Ri = 2KΩ) ​​tube.
12AU7: famous low transconductance dedicated communications measurement of high resistance tube.
12AT7: "burning circles the quite famous air influenza excellent wideband, low noise, u tube.

Product Features:
● power cattle output cattle imported audio dedicated high silicon silicon steel sheet, layer and section wound around technology. Power cattle silicon steel: 114mm × stacked thick 60mm output cattle silicon steel: 96mm × stack thickness of 40mm. Quality nylon skeleton, high-purity oxygen-free copper wire.
● the Taiwanese production W.L or Wizard potentiometer volume control.
● Germany WIMA red MKP polypropylene coupling, mostly WIMA capacitor disassemble parts (on the market in order to look good charge new element), so the machine using second-hand German WIMA capacitor, but hundred percent German origin , newer appearance and are hereby acknowledged. Market on a domestic square capacitance line called polyester correction capacitor, colors are red, yellow, blue, looks beautiful, practical polyester capacitors.
● Taiwan's production and domestic carbon film resistor. Although the error and thermal noise is slightly larger than the metal film resistors, carbon film resistors recognize the sound of the carbon film is relatively warm. Actual thermal noise Carbon Film and almost no difference in the gold film. From warm timbre consider this machine default carbon film resistors, printed circuit board models scaffolding welding models using the military DaHongPao gold film resistors and carbon film mix.
● the rectifier part reference Marantz 9 lines, high-voltage secondary rectification technology, 5Z3P × 2 bile rectifier, four imported large pond and two inductor filter.
● improvement of the classic lines, famous 12AT7 × 2 voltage amplification 12AU7 × 2 inverted, 6N6 × 2 cathode output promote, push-pull class AB amplifier. Wider frequency
response, phase shift is smaller, higher fidelity.
● Transformer after most manufacturers often used in potting process, play the role of the insulation, moisture-proof, shock absorption, can greatly reduce the magnetic coupling through the chassis, reducing resonance to reduce noise.
