180Wrms x 2 channel stereo single-ended tube  hybrid power amplifier

This is one of our state-of-the-art hybrid power amplifiers that combines both the advantage of a transistor amps high current drive (tight bass and good speaker control) and single-ended vacuum tube amplification (warm and sweet sound with good depth, sound stage, and air). The transistor output stage is a voltage to current converter circuit without any NFB or voltage gain, so the non-linear sound of transistors can be greatly eliminated. Left behind is the high damping factor that controls the speaker more efficiently. The tube section is working in an optomized single-ended operation mode to achieve the purest and most natural tonal quality.

If you were unaware of this amplifier construction, and you judged the sound quality by listening only, you would believe it was a pure tube power amplifier and not a hybrid.

The 5U4G tube rectifier can further upgrade by our super rectifier STR-104 or higher models , direct plug and play without any mod required.

With this super rectifier adaptor, you can use 300B, 2A3 , 45 , 50 , 80, 83, 1616 , 3B28 or 866A as rectifier tubes option.
