IWISTAO Tube Amplifier Mono-block Integrated West Electric Master 2x8W Vacuum Tube 6F3 Drive 300B 5Z2P Rectifier
It is a dream vacuum tube 300B power amplifier with mature circuit design and handmade. Adopting a special high-performance output transformers, will give you a true 300B tone, slender high frequencies (rich triangle iron harmonics), full mid-range maturity, deep dive at low frequencies, and full tension (the tightness of the drum leather can be felt, and low-frequency dark surge) The ranking of the musicians, expression of the singer, and gesture of playing are fully displayed in front of our eyes. This unit also has a secret weapon, put on the tube cover, the sound is arrogant and dynamic, low-frequency control is excellent, bare tube sound is like lingering and soft, the drizzle in the autumn wind.
This unit is driven by an antique famous tube 6F3 (6BM8) composite tube, and its sound is delicate (0.8MA, U: 55 small signal amplifier triode; if 6SN7, requires 3-4ma,U: 13-15), and its dynamic range is large (-11v, u: 10 driver level; if 6sn7, -6v, u: 13), strong driving force (110vpp) is enough to drive the tube 300B (-70v), reduce distortion, and noble sound naturally comes to life!
At the same time, the high-performance packaged output transformer, adopts a complex process and a high-tech design with imports Red Bull Iron Core 86 * 45 from United Kingdom. Selected high-quality enameled wires, CNC drying, vacuum dipping, moisture-proof packaging, and refining Made.
Also it adopts reasonable wiring layout, purely build a shed, reduce the distributed capacitance, and make the high-frequency expansion wider. Reasonable foreign old-fashioned supplementary accessories, and after one year adjusting sound, it is recommended not to modify or upgrade other vacuum tubes. We pursue perfect sound, this 300B tube amplifier is already tuned to a sound limit level after assembled above accessories , and it conveys the spirit of music and culture.
