100Wrms / channel single-ended tube  hybrid power amplifier

This is one of our state-of-the-art hybrid power amplifiers that combines both the advantage of transistors 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 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 and high output current that controls the speaker more efficiently. The tube section is working in an optomized single-ended operation mode.

If you were  unaware this was a hybrid amplifier and you judged the sound quality by listening only, you would believe it was a pure tube power amplifier. This version can be considered as a super enhanced version of the lower model HP-100.

Middle photo sets shows super up-grade version with multiples of big filter capacitors, a tube rectifier, and an upgraded power Tx.

New Mk2 design with over current protection circuit as well as enhanced dynamics design

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 and more as rectifier tubes option.
