Virtues of the 300 B valve amplifier

We started with vocals and strings, where the strength of the 300B lies. If not reproduced properly, the advantage of the
300B would be rendered vain, even with good driving power!

In addition, the Jubilee 300B also provides high or low gain setting, low frequency cutoff filter (under 100Hz), level
adjustment and attenuation ratio settings, which are not of routine operation and require the aid of an authorized
service technician..... The main boards use double-sided printed circuit boards with 70 micron copper tracks, ceramic
tube sockets with pure silver contacts, and professional low inductance electrolytic capacitors.

A rigorous challenge indeed

..... According to the manufacturer, in principle, the Jubilee 300B can perfectly drive a speaker with a sensitivity as low as
82dB to higher than 106dB. For the loyal 300B aficionados, using speakers that they want to play but don't dare to think
about will now become a reality.

We specially borrowed the Focal Scala Utopia EVO that partnered the Jubilee 300B at the Munich High End Show 2019
for auditioning in our 450-square- foot Hi-Fi room. The sensitivity of the Scala Utopia EVO is not particularly high at 92
dB. Considering the recommended amplifier power of 40-500 watts, the three-way speaker with a 11-inch bass driver
and a 6-inch midrange unit and the space of 450 square feet, this was a vigorous challenge to the 300B power tubes.
Nevertheless, the Jubilee 300B proves that the inherent limitations of the past 300B are over.
