OTO SE 35 35th Anniversary Edition

Audio Note (UK) marks 35 years of its Oto integrated amplifier with the Oto SE 35 35th Anniversary Edition, described as the most substantial redesign in decades.

Originally launched in 1991, the single-ended pentode tube amplifier was Audio Note’s first fully in-house design, proving high musicality at a more accessible price.

The anniversary model introduces newly designed output transformers, an upgraded choke-based power supply, optimized timing constants, and revised output stage circuitry.
