Octave Jubilee 300 B Mono Power Amplifier (Pair)
63800,00 €
The Octave’s objective was to develop a Jubilee 300 B amplifier that provides enough power for most speakers, while not interfering with the classic 300 B circuit. It was not about power for the sake of power, but about providing the Jubilee 300 B with a perfect environment that enhances the tonal qualities of this tube. The concept of a 300 B single-ended amplifier delivering 20-30W output power with three power tubes in indirect parallel operation was thus born.
Overview
There is a fundamental problem regarding “direct” heating of the triodes: Unlike indirectly heated tubes (such as the KT88, KT120, etc.), directly heated triodes cannot operate directly in parallel because of the complex demands on the heating system needed increase output power.
The typical 50 Hz AC heater voltage would cause unacceptably high hum and power disturbances in the speaker. Although DC heating eliminates the hum, it also limits the sonic potential of the 300B.
Octave’s solution: We have developed a 7 Hz power generator that supplies each of the three 300B tubes with a separate, regulated 7 Hz pure sine wave heating voltage.
- This makes it possible to connect several 300B tubes in parallel.
- Sound-affecting ripple and RF disturbances of the line frequency are completely eliminated.
- Heating and operating voltage are electronically controlled, sound instabilities due the fluctuating mains voltage is a thing of the past.
- Only then can the tonal potential of the 300B be fully exploited. The 300B tubes will now operate in the optimized region and can fully develop their tonal qualities. Now it becomes clear why she is called the “queen” of tubes.
Thus, the Octave Jubilee 300 B is an absolutely modern and uncompromising implementation of arguably the finest amplification technology in the high-end sector. The amp offers an emotional, smooth, highresolution, dynamic and expansive triode sound, not only in the mid/high frequency range, but for the first time, completely across the full audio band.
Jubilee 300 B, a new generation of single ended amplifier technology without limitations.
