A note from the designer/builder:
"This particular amplifier is an excellent performer and would make a great fit for anyone with a line stage (or source that has level control) and higher sensitivity loud speakers (90dB 1W at 1 meter, and above). The bass extension is remarkable with the -3dB corner at 18Hz so this amp will provide all the bass you will need (making it a great fit for acoustic jazz among other genres). The high frequency performance is excellent as well which means the in-band audio is essentially flat in its frequency response. The noise floor is extremely low and the channel seperation (which provides the "in the room" type imaging) is on another level. The narrower enclosure makes for a really cool look and the hand picked, cut, sanded, and oiled aged White Oak from Ed's wood collection is the aesthetic icing on the cake of a sweet amplifier."

Jazz 6DJ8 - EL34 6W Single-Ended Class A Stereo Power Amplifier
Jazz is a hand‑built single‑ended amplifier created for listeners who value tone, nuance, and musicality above all else. A 6DJ8/E88CC front end drives an EL34 output stage, producing the classic SET character: rich harmonic texture, holographic imaging, and an intimate, lifelike midrange.
Output is 6 watts RMS per channel into 8 Ω, making Jazz an ideal partner for high‑efficiency loudspeakers. A carefully tuned circuit provides wide, even bandwidth with solid bass extension and smooth, extended highs. The noise floor is exceptionally low, allowing the amplifier to present music against a quiet, transparent background.
This amplifier is point‑to‑point wired and voiced by ear, using quality components throughout: metal‑film resistors, film capacitors, robust transformers, and a carefully engineered grounding scheme that ensures ultra‑low hum and stable operation.
If you’re looking for a pure, expressive, and musical single‑ended amplifier with modern clarity and classic warmth, Jazz brings the performance to life.
