140W x 2ch high current single-ended tube hybrid power amplifier

This is one of our new state-of-the-art 2014 design 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 tubes amplification (warm and sweet sound with good depth, sound stage, and air). The conventional output transformer of single-ended tube amplifier is replaced with a super high current, high damping factor solid-state transformer, which can output max. peak music power of 140W/ch at 4 ohm loading , this amplifier can even drive down to 2 ohm without problem. Built-in over-temperature and over-current protection for safety operation even under extreme condition. The tube section is working in an optomized pure class A single-ended operation mode to achieve the purest and most natural tonal quality.

This amplifier has a very special feature of "Solid-state only" or "Tube and Solid-state" mode selector, you can choose it to use as pure solid-state high power high current amplifier, or you can convert it into a single-ended tube hybrid power amplifier. The tube section can even use tons of different power tubes like 6550, EL34, 6L6, 6V6, 6F6, 6K6, 5881, 6CA7, KT66,KT77,KT88...etc. The new 2105 UX version can even take the KT120 and KT150 power tubes , as well as EL32 NOS Mullard tubes.

Also come with input level / gain control, this feature can make this amp use as a single input integrated amplifier, or use in multiple amplifier (bi-amp / tri-amp ) mode , and can easily balance the gain between different power amplifiers..

If you were unaware of this amplifier's construction, and you judged the sound quality by listening only, you would believe it was a pure tube power amplifier and not a hybrid.You can then have both the smooth and silkiness of single-ended sound with very good punch, rich and controlled bass.
