The Mira Ceti 300B is one of the few Single Ended (SE) tube amplifiers in the world made with toroidal speaker transformers, now in a renewed take.
Mira Ceti MK2 is a renewed take on Fezz's classic single ended amplifier built around the legendary 300B triodes and custom toroidal output transformers. The redesigned circuit, upgraded signal path and refined component selection elevate the amplifier’s clarity, coherence and emotional impact. Despite its modest output power, the Mira Ceti MK2 delivers a remarkably vivid and intimate presentation. Its sound blooms with a rich, textured midrange, a smooth and delicate top end and a surprisingly confident bass foundation for a SE design. It shines with vocal, acoustic, classical and jazz recordings — music that rewards tonal beauty and natural expression. The new model features a delayed anode voltage activation system, protecting the tubes during startup and extending their lifespan. Automatic bias control continually maintains optimal tube parameters, eliminating the need for manual adjustments. Mira Ceti MK2 blends the timeless charm of directly heated triodes with contemporary engineering. Purity, colour, nuance and the kind of musical honesty only a true 300B design can offer.
