Product Description:
◆ Chassis is made of stainless steel of 1.2mm in thickness with wire brushing.

◆ Big metal knob, comb-like feet for reducing shaking.

◆ High-grade RCA terminal with gold plating.

◆ 4Ω and 8Ω power output terminals with gold plating.
◆ Side panels made from cherry wood.
◆ Blue power indicator.

Using silver 1.0mm thick brushed stainless steel craft box.

Wrinkle paint process cattle enclosures.

● metal knob cap, the cellular machine feet.

● the use of gold-plated RCA signal input lotus seat.

● Adopt with oxidation amber gold-plated output terminal.

● red cherry wood side of the decorative sheet, elegant and dignified.

● Blue LED power indicator.

● the performance of pre-thumb tube Description:

6N6T: high mutual conductance (S = 11mA / V), the amplification factor (u = 20), low internal resistance (Ri = 2KΩ) tube.

12AU7: well-known low transconductance, the high resistance of the communication measurement tube.

12AT7: the burning world “quite famous air excellent sense of wideband, low noise, u tube.
Product characteristics:

Power cattle output cattle imported audio-specific silicon silicon steel layer and section wound around technology. Cow power silicon steel: 114mm × stacked thick 60mm output
cattle silicon steel: 96mm × stack thickness 40mm. High-quality nylon frame, high-purity oxygen-free copper wire.

● Taiwan production W.L Wizard potentiometer volume control.

● input within the machine using Teflon silver plated shielded signal lines, strong anti-interference, transmission failure decreased.

● German WIMA red MKP polypropylene coupling.

● PCB model using sets of domestic production and some carbon film resistors; scaffolding welding models feature military Dahongpao metal film resistors, carbon film mix.

● high-voltage secondary rectifier, 5Z3P × 2 gall rectifier, four imported large pond and two inductor filter.

● reference to the improvement of the classic lines, famous 12AT7 x 2 voltage amplification, 12AU7 × 2 phase inversion, 6N6 × 2 cathode output driven, push-pull class AB
amplification. A wider frequency response, phase shift to smaller, higher fidelity.

● Transformer with epoxy potting, solid and reliable, high temperature, insulation, moisture, shock absorption and play a role, can greatly reduce the magnetic coupling through

the chassis to reduce resonance, and reduce noise.
