50Wrms x 2ch high current single-ended tube hybrid integrated amplifier

This is one of our new state-of-the-art design hybrid integrated amplifiers that combines both the advantage of a transistor amp's high current drive (tight bass and good speaker control) and single-ended vacuum tubes pure class A amplification (warm and sweet sound with excellent depth, wide open and airy sound stage).

The conventional output transformer of single-ended tube amplifier wss replaced with a super high current, high damping factor solid-state transformer, which can output 50W continuous power per channel at 8 ohm loading , this amplifier can drive down to 4 ohm without problem, even 2 ohm possible with reasonable loudness level. Built-in over-temperature and over-current protection for safety operation even under extreme condition. The tube section is working in pure class A single-ended operation in order to achieve the purest and most natural ORGANIC tonal quality. .

This amplifier has a very flexible tube rolling capabilities, default tube is 6SL7 or 6SN7 of your choice, it can replaced with 6SU7, ECC32, ECC33 and ECC35 or equivalent models to change the tonal character. With optional "Big tube converter" , it can even use tons of different power tubes like 6550, EL34, 6L6, 6V6, 6F6, 6K6, 5881, 6CA7, KT66,KT77,KT88...etc.With the use of big size tubes, the tonal character will be more natural, open and airy.

This integrated amplifier comes with 3 sets of inputs for flexible connectivity.

If you judged the sound quality by ear, you would believe it is a pure tube single-end high power amplifier which worth over $10K in the industry.

Option : Big tube converter $100 per pair ( can replace the default tube and use above mentioned big power tubes)
