Weiliang Breeze WBAHPA Wada Shigeho 12ax7 12au7 Tube Preamplifier

• The line reference to Wada  Shigeho's style circuit to  improve lines and adjust according to the different uses of the bile duct peripheral component parameters to maximize the strengths of the bile duct , so that the machine can no matter what the outstanding performance of the bile duct .

• Japanese Wada  Shigeho's launched in the early 1960s, the performance is excellent.

• It maintained a Marantz7 mellow and full of musical taste characteristics, and in the sound field , transparent flu and Marantz7 enough to keep pace .

• But regardless dynamic , transient, high frequency response , power analysis , signal to noise ratio than Marantz7 good ,

• Military grade metal film resistor from Bejing 718 nationa-owned factory

• Fully rectified&filtered DC power for filament and plate/anode,Very lowe noise

• Dual sides FR4 PCB board with gold cated

• Rectifieredregulated power for plate and filaments for low noise
