The Octave Audio Jubilee 300B circuit is based on electronic power supplies for each 300V lamp, which guarantees the operation of three "tubes" in parallel mode. The voltage and heat dissipation are adjusted automatically, which significantly increases the lamp life and sound quality.
The Octave Jubilee Mono Ultimate reaches 225 watts of dynamic output power – the capabilities of large-scale power transformers and proprietary circuitry extend far beyond the traditional concepts of lamp technology. The device body is assembled from 8 mm aluminum, 2 mm steel and 50 mm X-MDF plates.
