About the SE84UFO
The Decware SE84UFO is a minimalist, high-end Zen Triode amplifier designed by Steve Deckert and hand-built in the USA. It features a very simple audio circuit with only two resistors and one capacitor, no circuit boards, and zero negative feedback, resulting in a pure and transparent sound. The amplifier delivers 2.3 watts RMS per channel into 8 ohms and can handle speaker loads down to 1 ohm. It uses EL84 or 6P15P-EV output tubes and a 6922/6N1P input tube, with a 5U4 rectifier tube. The UFO output transformers are highly interleaved for ultra-fidelity and wide bandwidth. The SE84UFO is self-biasing and self-balancing, requiring minimal maintenance other than tube replacement every few years. It has a frequency response from 20 Hz to 80 kHz, input sensitivity of about 1.8 to 2 volts, and a power consumption of 65 watts. The amplifier weighs 17 lbs and measures 8.0" H x 6.125" W x 12.0" D. It comes with a lifetime warranty to the original owner and offers various customization options including wood bases and knob types. The SE84UFO has undergone 7 revisions over 16 years, reflecting continuous improvements based on customer feedback.
