The four rods strengthen the support of the tube core, as stable as Mount Tai. The voice is exquisite, the details are more abundant, more transparent, delicate, mellow, the air sense, the sense of hierarchy, the analytic power is stronger, and the gall flavor has more advantages. This product is designed and produced by Changsha Qiangsheng Electronic Tube Factory, a high-end designer and craftsman. This is the most successful product for copying WE300B electronic tubes in China at present, completely 1:1 copying WE300B. The appearance is long and elegant, which is completely comparable to the original Xidian tube. The cathode activity is superior to that of the ordinary 300B tube. The platinum grid removes the return grid current, and the sound quality is pure and sweet. The superconducting anode material is covered with a radiation and heat dissipation coating, which greatly improves the board consumption. The whole tube works easily and freely. The one-to-one process ensures that each tube is accurately paired with high-quality products, ensuring that customers can use it with confidence.</span></p><p><br/></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">WE300B Voice:</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">It is soft and delicate, with high sound density, richer details, stronger analytical power, pure, sweet and mellow, and outstanding sense of hierarchy,.</span></p><p><br/></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">WE300B directly heated cathode medium power triode, used for Class A1 amplification.</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">It is suitable for 10W output power in audio amplifier.</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Filament heating</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Uf (DC).…5V</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">lf(DC)-………1.2A</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Static parameters</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Ua……………300V</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">-Ug·………… 60V</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">la……60mA</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Gm---5.5mA/V</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">ri-.………0.7 KΩ</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">u……3.85</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Pout……… 6.6W</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Limit rating</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Anode voltage...... 480V</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Anode dissipation power...... 40W</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Cathode current</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Self bias voltage........ 100 mA</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Fixed bias voltage...... 70 mA</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Interelectrode capacitance</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Input capacitance... 9PF</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Output capacitance......... 4.3PF</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">Cross circuit capacitance............. 15PF</span></p><p><br/></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">The shop promises:</span></p><p><span style="font-size:20px;font-family:&quot;times new roman&quot;, times, serif">The electronic tubes operated by our store are guaranteed to be brand new and high-quality genuine products from the original factory, and we will provide free replacements for any quality problems within one year.
