Single-Ended Triode amplifiers excel in clarity and dimensionality compared to solid state and push-pull amplifiers. SET amplifiers capture the presence and fine detail of a live musical performance similar to the sound of great analog vinyl records. A well designed tube-based SET amplifier is the audiophile's choice for true high fidelity sound reproduction.​ Our TriodeCraft 300B monoblock power amplifier achieves this goal. ​
Single-ended circuits are simple: As close to “straight wire with gain” with a minimum number of discrete component parts. “Brick wall” Class-A constant current source power supply. Electrons flowing through a vacuum instead of a piece of silicon. TriodeCraft's proprietary circuit design and quality component parts advances 'classic old school' SET circuits to the highest performance level. Listening impression: The TriodeCraft 300B power amplifier presents music very dynamically; Tight powerful bass and midbass, uncanny midrange dimensionality, and extended open highs thanks to a large capacity power reservoir and superlative transformer design. Reference level performance for the avid music lover.
​​​​
Dual chassis monoblock construction dedicates an amplifier for each speaker system for the lowest distortion and highest musical clarity. Advanced circuit design and quality component parts ensure long term reliability.​​ The TriodeCraft 300B power amplifier is a serious no compromise design.

Our 300B power amplifier includes a separate Power Supply and Audio Unit for each channel. This design offers optimal parts layout, complete isolation of magnetic fields, and less unit weight for ease in handling and placement.

    Customer Comments

    Sonic Impression:  A very three dimensional presentation, one is transported to the venue. Layers and layers of depth and sense of space including room echo. Keyboards and guitars are 'in the room.' Bell like sound of cymbals, snare drum rasp, and drum head ring. Double bass is dark and sonorous. Vocals are natural without strain. No solid state or pentode tube amp I have auditioned comes close. JS, Sedona AZ​

    It is important to me to know the parts quality in an audio product since this is what determines the best from the rest. I have learned that the key to a really great 300B amp is the quality of the "iron." Many companies use low grade generic transformers, chokes, electrolytic capacitors, and silicon parts that color the sound. These are the amps that are known for their syrupy mids, rolled-off highs, and woolly bass. The Triodecraft 300B avoids these pitfalls and guarantees the audio devotee the best sonic experience. AK, Tokyo Japan

    I auditioned the Triodecraft monoblock amplifiers at a friend's studio. In a word it was scary real! The left channel keyboards were right in front of me. The drummer on the right channel cracking the rims and I could tell they were Vic Firth sticks. The electric bass buzzed my chest and it was a Percy Jones' custom Ibanez. No amplifier in my experience has presented such a vivid and precise soundstage. Just add a good set of high efficiency speakers and you will be at the "club." RB, Los Angeles CA
