Classic No.9.0 Tube Pre-amplifier

No.9.0 is a type of tube pre-amplifier. Its main amplifying circuit adopts improved SRPP circuit. It was designed to be ultra-thin build (45MM in height) and separated power supply. Its sound features a little distinction between traditional tub amplifiers. On one hand it keeps the sound characteristic of nature and fluency that tube amplifier features, on the other hand it can provide the sound characteristics, such as transparence and clarity, strong sensation of 3D, sharp-cut bass and less acoustic coloring, especially being suitable for playing classical music.

Functions and features:

Full remote function, separated power supply, R-shaped power transformer, choke filter, transistor voltage regulation, soft start filament, output time-lag protection, 2ounce copper foil on both sides of PCB , name brand tubs and components(WIMACAP SOLON CAP PHILIPS TUBE ALPS VOL and military grade resistors, etc).
