100Wrms / channel single-ended tube  hybrid power amplifier

This is one of our state-of-the-art hybrid power amplifiers that combines the advantage of transistors high current drive (tight bass and good speaker control) with 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 Negative Feedback or voltage gain so the non-linear sound of transistors can be eliminated while preserving the high damping factor and high output current that controls the speaker more efficiently. The tube section is working in an optimized single-ended operation mode and we have designed a sophisticated tube auto biasing circuit that allows you to listen to your music without worrying about adjusting tube bias. The new Mk2 design has an over current protection circuit (optional) as well as enhanced dynamics.
If you were unaware that this was a hybrid amplifier while you listened to music we are confident that you would judge it to be the sound quality of a pure tube power amplifier. This version can be considered as a super enhanced version of the lower model HP-100 with a 5U4G tube rectifier stage added.
We have included both RCA and XLR inputs along with high quality 5 way binding posts.
Middle photo sets shows super up-grade version with multiples of big filter capacitors, a tube rectifier, and an upgraded power Tx.
Free Demi-tube upgrade with new orders
For an upgrade you can add any of our super rectifiers including the STR-104, STR-1001, and STR-1002 without any modification required.

With this super rectifier adaptor, you can use modify for the sound that you like using 300B, 2A3 , 45 , 50 , 80, 83, 1616 , 3B28 or 866A tubes.
